Before launching into the news, I have a few explanatory bits, which can be easily skipped.
Fusion energy
There’s a lot of interest in fusion energy, a form of nuclear energy, that promises to be sustainable and ‘clean’. Adam Stein’s May 29, 2024 article “Nuclear fusion: the true, the false and the uncertain” for Polytechique insights (Institut polytechnique de Paris) tempers some of the enthusiasm/hype about fusion energy. In this excerpt, he examines claims about ‘clean’ energy, Note: A link has been removed,

#2 Fusion will become a source of clean, limitless energy
TRUE — Fusion is generally seen as “clean” energy.
It produces substantially less radioactive “waste” than fission – though it is possible that with emerging technologies, waste from fusion and fission could be reused. Still, like other nuclear fission, fusion will require appropriate and comprehensive oversight. One concern is that the reaction could be used to generate fissile materials usable in weapons. Fusion machines and related reactions do not directly produce material useful for weapons. The reaction does, however, create an enormous amount of neutrons.
On the bright side, these neutrons could help generate more fuel for the fusion reaction — many designs plan to incorporate a “breeding blanket,” a layer of materials that acts as heat insulation, but is also lined with materials that can capture the neutrons to create more tritium. Uranium or thorium could also be placed in some breeding blanket designs. The concern is that these materials, once irradiated, could generate uranium-235 that can be used in nuclear weapons. Physical ways to deter this process exist, such as requiring the use of lithium‑6 in the blanket modules. The IAEA [International Atomic Energy Agency] will be important in ensuring non-proliferation safeguards and oversight.

ITER
The International Thermonuclear Experimental Reactor (ITER) is (from its Wikipedia entry), Note: Links have been removed,
ITER (initially the International Thermonuclear Experimental Reactor, iter meaning “the way” or “the path” in Latin)[4][5][6] is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun. It is being built next to the Cadarache facility in southern France.[7][8] Upon completion of the main reactor and first plasma, planned for 2033–2034,[9][10] ITER will be the largest of more than 100 fusion reactors built since the 1950s, with six times the plasma volume of JT-60SA in Japan, the largest tokamak operating today.[11][12][13]
The long-term goal of fusion research is to generate electricity; ITER’s stated purpose is scientific research, and technological demonstration of a large fusion reactor, without electricity generation.[14][11] ITER’s goals are to achieve enough fusion to produce 10 times as much thermal output power as thermal power absorbed by the plasma for short time periods; to demonstrate and test technologies that would be needed to operate a fusion power plant including cryogenics, heating, control and diagnostics systems, and remote maintenance; to achieve and learn from a burning plasma; to test tritium breeding; and to demonstrate the safety of a fusion plant.[12][8]
ITER is funded and operated by seven member parties: China, the European Union, India, Japan, Russia, South Korea and the United States. In the immediate aftermath of Brexit, the United Kingdom continued to participate in ITER through the EU’s Fusion for Energy (F4E) program until September 2023.[15][1][2] Switzerland participated through Euratom and F4E until 2021,[16] though it is poised to rejoin in 2026 following subsequent negotiations with the EU.[17][18] ITER also has cooperation agreements with Australia, Canada, Kazakhstan and Thailand.[19]
Construction of the ITER complex in France started in 2013,[20] and assembly of the tokamak began in 2020.[21] The initial budget was close to €6 billion, but the total price of construction and operations is projected to be from €18 to €22 billion;[22][23] other estimates place the total cost between $45 billion and $65 billion, though these figures are disputed by ITER.[24][25] Regardless of the final cost, ITER has already been described as the most expensive science experiment of all time,[26] the most complicated engineering project in human history,[27] and one of the most ambitious human collaborations since the development of the International Space Station (€100 billion or $150 billion budget) and the Large Hadron Collider (€7.5 billion budget).[note 1][28][29]
ITER’s planned successor, the EUROfusion-led DEMO, is expected to be one of the first fusion reactors to produce electricity in an experimental environment.[30]
…
Tokamak
As this comes up again in the next section, here’s more about the tokamak from its Wikipedia entry, Note: Links have been removed,
A tokamak (/ˈtoʊkəmæk/; Russian: токамáк) is a device which uses a powerful magnetic field generated by external magnets to confine plasma in the shape of an axially symmetrical torus.[1] The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power. The tokamak concept is currently one of the leading candidates for a practical fusion reactor for providing minimally polluting electrical power.[2]
In a landmark achievement for fusion energy, ITER has completed all components for the world’s largest, most powerful pulsed superconducting electromagnet system.
ITER is an international collaboration of more than 30 countries to demonstrate the viability of fusion—the power of the sun and stars—as an abundant, safe, carbon-free energy source for the planet.
The final component was the sixth module of the Central Solenoid, built and tested in the United States. When it is assembled at the ITER site in Southern France, the Central Solenoid will be the system’s most powerful magnet, strong enough to lift an aircraft carrier.
The Central Solenoid will work in tandem with six ring-shaped Poloidal Field (PF) magnets, built and delivered by Russia, Europe, and China.
The fully assembled pulsed magnet system will weigh nearly 3,000 tons. It will function as the electromagnetic heart of ITER’s donut-shaped reactor, called a Tokamak.
How does this pulsed superconducting electromagnet system work?
Step 1. A few grams of hydrogen fuel—deuterium and tritium gas—are injected into ITER’s gigantic Tokamak chamber.
Step 2. The pulsed magnet system sends an electrical current to ionize the hydrogen gas, creating a plasma, a cloud of charged particles.
Step 3. The magnets create an “invisible cage” that confines and shapes the ionized plasma.
Step 4. External heating systems raise the plasma temperature to 150 million degrees Celsius, ten times hotter than the core of the sun.
Step 5. At this temperature, the atomic nuclei of plasma particles combine and fuse, releasing massive heat energy.
A tenfold energy gain
At full operation, ITER is expected to produce 500 megawatts of fusion power from only 50 megawatts of input heating power, a tenfold gain. At this level of efficiency, the fusion reaction largely self-heats, becoming a “burning plasma.”
By integrating all the systems needed for fusion at industrial scale, ITER is serving as a massive, complex research laboratory for its 30-plus member countries, providing the knowledge and data needed to optimize commercial fusion power.
A global model
ITER’s geopolitical achievement is also remarkable: the sustained collaboration of ITER’s seven members—China, Europe, India, Japan, Korea, Russia, and the United States. Thousands of scientists and engineers have contributed components from hundreds of factories on three continents to build a single machine.
Pietro Barabaschi, ITER Director-General, says, “What makes ITER unique is not only its technical complexity but the framework of international cooperation that has sustained it through changing political landscapes.”
“This achievement proves that when humanity faces existential challenges like climate change and energy security, we can overcome national differences to advance solutions.”
“The ITER Project is the embodiment of hope. With ITER, we show that a sustainable energy future and a peaceful path forward are possible.”
Major progress
In 2024, ITER reached 100 percent of its construction targets. With most of the major components delivered, the ITER Tokamak is now in assembly phase. In April 2025, the first vacuum vessel sector module was inserted into the Tokamak Pit, about 3 weeks ahead of schedule.
Extending collaboration to the private sector
The past five years have witnessed a surge in private sector investment in fusion energy R&D. In November 2023, the ITER Council recognized the value and opportunity represented by this trend.
They encouraged the ITER Organization and its Domestic Agencies to actively engage with the private sector, to transfer ITER’s accumulated knowledge to accelerate progress toward making fusion a reality.
In 2024, ITER launched a private sector fusion engagement project, with multiple channels for sharing knowledge, documentation, data, and expertise, as well as collaboration on R&D. This tech transfer initiative includes sharing information on ITER’s global fusion supply chain, another way to return value to Member governments and their companies.
In April 2025, ITER hosted a public-private workshop to collaborate on the best technological innovation to solve fusion’s remaining challenges.

How have ITER’s Members contributed to this achievement?
Under the ITER Agreement, Members contribute most of the cost of building ITER in the form of building and supplying components. This arrangement means that financing from each Member goes primarily to their own companies, to manufacture ITER’s challenging technology. In doing so, these companies also drive innovation and gain expertise, creating a global fusion supply chain.
Europe, as the Host Member, contributes 45 percent of the cost of the ITER Tokamak and its support systems. China, India, Japan, Korea, Russia, and the United States each contribute 9 percent, but all Members get access to 100 percent of the intellectual property.
United States
The United States has built the Central Solenoid, made of six modules, plus a spare.
The U.S. has also delivered to ITER the “exoskeleton” support structure that will enable the Central Solenoid to withstand the extreme forces it will generate. The exoskeleton is comprised of more than 9,000 individual parts, manufactured by eight U.S. suppliers. Additionally, the U.S. has fabricated about 8 percent of the Niobium-Tin (Nb3Sn) superconductors used in ITER’s Toroidal Field magnets.
Russia
Russia has delivered the 9-meter-diameter ring-shaped Poloidal Field magnet that will crown the top of the ITER Tokamak.
Working closely with Europe, Russia has also produced approximately 120 tonnes of Niobium-Titanium (NbTi) superconductors, comprising about 40 percent of the total required for ITER’s Poloidal Field magnets.
Additionally, Russia has produced about 20 percent of the Niobium-Tin (Nb3Sn) superconductors for ITER’s Toroidal Field magnets.
And Russia has manufactured the giant busbars that will deliver power to the magnets at the required voltage and amperage, as well as the upper port plugs for ITER’s vacuum vessel sectors.
Europe
Europe has manufactured four of the ring-shaped Poloidal Field magnets onsite in France, ranging from 17 to 24 meters in diameter.
Europe has worked closely with Russia to manufacture the Niobium-Titanium (NbTi) superconductors used in PF magnets 1 and 6.
Europe has also delivered 10 of ITER’s Toroidal Field magnets and has produced a substantial portion of the Niobium-Tin (Nb3Sn) superconductors used in these TF magnets.
And Europe is creating five of the nine sectors of the Tokamak vacuum vessel, the donut-shaped chamber where fusion will take place.
China
China, under an arrangement with Europe, has manufactured a 10-metre Poloidal Field magnet. It has already been installed at the bottom of the partially assembled ITER Tokamak.
China has also contributed the Niobium-Titanium (NbTi) superconductors for PF magnets 2, 3, 4, and 5, about 65 percent of the PF magnet total—plus about 8 percent of the Toroidal Field magnet superconductors.
Additionally, China is contributing 18 superconducting Correction Coil magnets, positioned around the Tokamak to fine-tune the plasma reactions.
China has delivered the 31 magnet feeders, the multi-lane thruways that will deliver the electricity to power ITER’s electromagnets as well as the liquid helium to cool the magnets to -269 degrees Celsius, the temperature needed for superconductivity.
Japan
Japan has produced and sent to the United States the 43 kilometers of Niobium-Tin (Nb3Sn) superconductor strand that was used to create the Central Solenoid modules.
Japan has also produced 8 of the 18 Toroidal Field (TF) magnets, plus a spare—as well as all the casing structures for the TF magnets.
Japan also produced 25 percent of the Niobium-Tin (Nb3Sn) superconductors that went into the Toroidal Field magnets.
Korea
Korea has produced the tooling used to pre-assemble ITER’s largest components, enabling ITER to fit the Toroidal Field coils and thermal shields to the vacuum vessel sectors with millimetric precision.
Korea has also manufactured 20 percent of the Niobium-Tin (Nb3Sn) superconductors for the Toroidal Field magnets.
Additionally, Korea has manufactured the thermal shields that provide a physical barrier between the ultra-hot fusion plasma and the ultra-cold magnets.
And Korea has delivered four of the nine sectors of the Tokamak vacuum vessel.
India
India has fabricated the ITER Cryostat, the 30-metre high, 30-metre diameter thermos that houses the entire ITER Tokamak.
India has also provided the cryolines that distribute the liquid helium to cool ITER’s magnets.
Additionally, India has been responsible for delivering ITER’s cooling water system, the in-wall shielding of the Tokamak, and multiple parts of the external plasma heating systems.
In total, ITER’s magnet systems will comprise 10,000 tons of superconducting magnets, with a combined stored magnetic energy of 51 Gigajoules. The raw material to fabricate these magnets consisted of more than 100,000 kilometers of superconducting strand, fabricated in 9 factories in six countries.

Vancouver’s (Canada) General Fusion news
Recently, there have been some big ups and downs for General Fusion as this May 5, 2025 General Fusion news release written as an open letter from the company’s Chief Executive Office (CEO), Greg Twinney
General Fusion has been at the forefront of fusion technology development for more than 20 years. Today, we stand as a world leader on the cusp of our most exciting technical milestone yet—and one of the most challenging financial moments in our history. We are closer than ever to delivering practical fusion, but success depends on securing the right financing partners to carry this breakthrough forward.
On April 29th [2025], we achieved a transformative milestone at our Vancouver, B.C., headquarters in Canada—we successfully compressed a large-scale magnetized plasma with lithium using our world-first LM26 fusion demonstration machine. The full, integrated system and diagnostics operated safely and as designed, and an early review of the data indicates we saw ion temperature and density increase, and our lithium liner successfully trapped the magnetic field. This was an incredible success for our first shot! What does this mean? From a technology perspective, we’re one step closer to bringing zero-carbon fusion energy to the electricity grid using our unique, home-grown Canadian technology that global industry leaders recognize as one of the most practical for commercialization.
Our incredible, innovative, and nimble team achieved these results about a year and a half after we launched the LM26 fusion demonstration program—designing, building, commissioning, optimizing, and operating on a rapid timeline with constrained capital. LM26 is the only machine of its kind in the world, designed and built to achieve the technical results required to scale a fusion technology to a practical power plant. It is backed by peer-reviewed scientific results published in 2024 and 2025 issues of Nuclear Fusion, making us one of only four private fusion companies in the world to have achieved and published meaningful fusion results on the path to scientific breakeven. We are also the only one with the machine already built to get there. Truly, there has never been a more promising time to be at—or invest in—General Fusion.
General Fusion has been around the block. We’ve proven a lot with a lean budget. We’re not a shiny new start-up with a drawing and a dream; we are experienced fusioneers with a clear view of the path to success and the machine to prove it. We’ve built a global network of partners and early adopters focused on a fusion technology—Magnetized Target Fusion—that is durable, cost-effective, fuel-sustainable, and practical. We are ready to execute our plan but are caught in an economic and geopolitical environment that is forcing us to wait.
Keeping a fusion company funded in today’s world requires more than just meaningful capital. It takes ambition, steadfast patience, a bold national vision aligned with the opportunity, and constant refreshing of the investor base as timelines stretch beyond typical fund horizons. Our mission has historically been supported financially by a mix of strong private investors and the Canadian federal government. We have been competing against aggressive nationally funded fusion programs around the world. We have risen to global leadership by charting a distinct course—founded on entrepreneurship and commercial focus—while others follow government-led or academic pathways. However, today’s funding landscape is more challenging than ever as investors and governments navigate a rapidly shifting and uncertain political and market climate.
This rapidly shifting environment has directly and immediately impacted our funding. Therefore, as a result of unexpected and urgent financing constraints, we are taking action now to protect our future with our game-changing technology and IP—including reducing both the size of our team and LM26 operations—while we navigate this difficult environment. We’re doing what resilient teams do and what we have done before: refocus, protect what matters, and keep building.
While this is a challenging time for General Fusion, it is also an attractive opportunity for those with the financial means to transform the world. Everything is in place—the technology, science, LM26, and the know-how and passion. All we need now is the capital to finish the job. We are opening our doors and actively seeking strategic options with investors, buyers, governments, and others who share our vision. Reach out now and become part of the future of energy.
Greg Twinney
Chief Executive Officer General Fusion, Inc.
Twinney also gave a May 8, 2025 radio interview(approximately 7 mins.) to Stephen Quinn of the Canadian Broadcasting Corporation’s (CBC) Early Edition.
May 8, 2025
General Fusion CEO, Greg Twinney tells Stephen Quinn how his company has made big breakthroughs in fusion energy – and how market chaos caused by President Trump has made it hard to find investors.
The interview provides an introduction to fusion energy and the company while this May 5, 2025 article by John Fingas for Betakit fills in some details, Note: Links have been removed,
…
In a statement, General Fusion told BetaKit it was looking for $125 million USD (about $172.7 million CAD) to fulfill its goals. While the company didn’t share the scope of the layoffs, The Globe and Mail reported that the company let go of a quarter of staff.
General Fusion created its first magnetized plasma, which is needed for its fusion reactions, at its LM26 demonstration facility in March [2025], and conducted a large-scale test on April 29. It still plans to create plasma at a hotter 10 million C within months, and eventually to reach the 100-million-degree mark needed to achieve a “scientific breakeven equivalent” where LM26 could generate more energy than required for the reaction.
…
The company ultimately hopes to deploy reactors based on its Magnetized Target Fusion technology, which creates fusion conditions in short pulses, by the mid-2030s. The technique theoretically costs less than the lasers or superconducting magnets used in designs like Tokamak reactors, and could be used in facilities close to the cities they serve. One 300-megawatt electrical plant powered by fusion could provide enough continuous power for 150,000 Canadian homes, the company claims.
The company has raised about $440 million CAD so far, including $69 million from the Government of Canada. Some of its private investors include Amazon founder Jeff Bezos, Shopify founder Tobi Lütke, and engineering consultancy Hatch. Bob Smith, the former CEO of Bezos’s spaceflight company Blue Origin, became a strategic advisor for General Fusion in early April [2025].

“We’re not a shiny new startup with a drawing and a dream; we are experienced fusioneers with a clear view of the path to success and the machine to prove it,” he [Greg Twinney, General Fusion CEO] said.
It seems logical to follow with this:
Business investments and fusion energy
First, here’s more about the agency, which released a 2025 report on investments in fusion energy. The European Union (EU) has created an organization known as Fusion for Energy (F4E), from its Wikipedia entry, Note: Links have been removed,
Fusion for Energy(F4E) is a joint undertaking of the European Atomic Energy Community (Euratom) that is responsible for the EU’s contribution to the International Thermonuclear Experimental Reactor (ITER), the world’s largest scientific partnership aiming to demonstrate fusion as a viable and sustainable source of energy. The organisation is officially named European Joint Undertaking for ITER and the Development of Fusion Energy and was created under article 45 of the Treaty establishing the European Atomic Energy Community by the decision of the Council of the European Union on 27 March 2007 for a period of 35 years.[1]
…
F4E recently released a report “Global investment in fusion private sector, 1st edition, Cutoff: 10 June 2025,” from the June 12, 2025 F4E press release,
The F4E Fusion Observatory has published its first-ever report, an analysis of global investment in the fusion private sector. Based on a collection of all available data, the analysis provides a picture of who is investing and where, showing rapid growth and significant geographical differences.
The figures reveal a sharp increase in investments in fusion start-ups in recent years. The total amount has grown from just over 1.5 billion EUR in 2020 to an estimated 9.9 billion EUR at present (June 2025), doubling in the last two years alone [emphasis mine]. The investment remains concentrated in the US, host of most private companies (38 out of 67), absorbing 60% of global funding. China comes second at 25%, with fewer projects (6) backed by large public funds [emphasis mine].
Meanwhile, Europe takes a smaller share of investment (5%) [emphasis mine], with Germany leading the continent at 460 M EUR million, just above the UK, at 416 M EUR. Among the EU’s seven private companies, the largest sums are received by Marvel Fusion and Focused Energy. F4E can support these emerging players by leveraging on its experience in large projects and knowledge of the market. For this purpose, F4E has an ongoing call inviting EU-based private fusion initiatives to collaborate.
The analysis goes on to present the origin and profile of the investors. While US funding is largely led by venture capital firms or big tech, those in the EU show a more even distribution between public and private investors.
As for the kinds of fusion concepts, magnetic confinement takes the lion’s share of global investment, at €6,1 billion, predominantly for Tokamaks (doughnut-shaped devices, similar to ITER). However, in Europe, inertial confinement technologies are the most funded in the private sector.
By contrast, when considering the public funding used for the in-kind contributions to ITER, the geographic distribution is rebalanced. The €6.8 billion invested by F4E in the EU supply chain is larger than other regions due to the EU’s larger share of the ITER project. This contribution has shaped a strong European industry, capable of delivering complex technologies for fusion. That said, investment in the supply chain, while substantial, has a different impact than equity in a fast-scaling fusion company.
The findings of the report will be discussed at the F4E Roundtable, a key stakeholder forum hosted this week by F4E in Barcelona. With these data-based insights, the F4E Observatory aims to support the policy conversation and help steer it towards the future EU fusion strategy.
It seems that Canadian fusion efforts are not on the EU’s radar.
Wrapping up
To state the obvious, it’s an exciting and volatile time. In addition to this latest breakthrough at ITER, my April 11, 2025 posting “The nuclear fusion energy race” covers some of what were then the latest international technical breakthroughs along with some coverage of how President Donald Trump’s tariffs were creating uncertainty for investors and, also, Bob Smith’s, former CEO of Jeff Bezos’ spaceflight company Blue Origin, recent appointment as a strategic advisor for General Fusion.
I wish General Fusion good luck in finding new investors and, while it’s not a perfect energy solution, I wish all the researchers the best as they race to find ways to produce energy more sustainably.
One last comment, it’s easy to forget in a time when Russia is conducting a war with Ukraine and Israel is conducting an ever evolving action against Palestine, Iran, and more that cooperation amongst ‘enemies’ is possible. The list of ITER full members (United States, Russia, Europe, China, Japan, Korea, India, Note: There are other member categories) is a reminder that even countries that often work at cross purposes can work together.
In addition to the competition to develop commercial quantum computing, there’s the competition to develop commercial nuclear fusion energy. I have four stories about nuclear fusion, one from Spain, one from Chine, one from the US, and one from Vancouver. There are also a couple of segues into history and the recently (April 2, 2025) announced US tariffs (chaos has since ensued as these have become ‘on again/off again’ tariffs) but the bulk of this posting is focused on the latest (January – early April 2025) in fusion energy.
Fission nuclear energy, where atoms are split, is better known; fusion nuclear energy is released when a star is formed. For anyone unfamiliar with the word tokamak as applied to nuclear fusion (which is mentioned in all the stories), you can find out more in the Tokamak Wikipedia entry.
In a pioneering approach to achieve fusion energy, the SMART device has successfully generated its first tokamak plasma. This step brings the international fusion community closer to achieving sustainable, clean, and virtually limitless energy through controlled fusion reactions.
The SMART tokamak, a state-of-the-art experimental fusion device designed, constructed and operated by the Plasma Science and Fusion Technology Laboratory of the University of Seville, is a worldwide unique spherical tokamak due to its flexible shaping capabilities. SMART has been designed to demonstrate the unique physics and engineering properties of Negative Triangularity shaped plasmas towards compact fusion power plants based on Spherical Tokamaks.
Prof. Manuel García Muñoz, Principal Investigator of the SMART tokamak, stated: “This is an important achievement for the entire team as we are now entering the operational phase of SMART. The SMART approach is a potential game changer with attractive fusion performance and power handling for future compact fusion reactors. We have exciting times ahead! Prof. Eleonora Viezzer, co-PI of the SMART project, adds: “We were all very excited to see the first magnetically confined plasma and are looking forward to exploiting the capabilities of the SMART device together with the international scientific community. SMART has awoken great interest worldwide.
When negative becomes positive and compact
The triangularity describes the shape of the plasma. Most tokamaks operate with positive triangularity, meaning that the plasma shape looks like a D. When the D is mirrored (as shown in the figure on the right), the plasma has negative triangularity.
Negative triangularity plasma shapes feature enhanced performance as it suppresses instabilities that expel particles and energy from the plasma, preventing severe damage to the tokamak wall. Besides offering high fusion performance, negative triangularity also feature attractive power handling solutions, given that it covers a larger divertor area for distributing the heat exhaust. This also facilitates the engineering design for future compact fusion power plants.
Fusion2Grid aimed at developing the foundation for the most compact fusion power plant
SMART is the first step in the Fusion2Grid strategy led by the PSFT team and, in collaboration with the international fusion community, is aimed at the most compact and most efficient magnetically confined fusion power plant based on Negative Triangularity shaped Spherical Tokamaks.
SMART will be the first compact spherical tokamak operating at fusion temperatures with negative triangularity shaped plasmas.
The objective of SMART is to provide the physics and engineering basis for the most compact design of a fusion power plant based on high-field Spherical Tokamaks combined with Negative Triangularity. The solenoid-driven plasma represents a major achievement in the timeline of getting SMART online and advancing towards the most compact fusion device.
The Plasma Science and Fusion Technology Lab of the University of Seville hosts the SMall Aspect Ratio Tokamak (SMART) and leads several worldwide efforts on energetic particles and plasma transport and stability towards the development of magnetically confined fusion energy.

China has made a business announcement and there is no academic paper mentioned in their January 21, 2025 press release on EurekAlert (also available on phys.org as a January 21, 2025 news item), Note: A link has been removed,
The Experimental Advanced Superconducting Tokamak (EAST), commonly known as China’s “artificial sun,” has achieved a remarkable scientific milestone by maintaining steady-state high-confinement plasma operation for an impressive 1,066 seconds. This accomplishment, reached on Monday, sets a new world record and marks a significant breakthrough in the pursuit of fusion power generation.
The duration of 1,066 seconds is a critical advancement in fusion research. This milestone, achieved by the Institute of Plasma Physics (ASIPP) at Hefei Institutes of Physical Scienece [sic] (HFIPS) of the Chinese Academy of Sciences, far surpasses the previous world record of 403 seconds, also set by EAST in 2023.
The ultimate goal of developing an artificial sun is to replicate the nuclear fusion processes that occurr [sci] in the sun, providing humanity with a limitless and clean energy source, and enabling exploration beyond our solar system.
Scientists worldwide have dedicated over 70 years to this ambitious goal. However, generating electricity from a nuclear fusion device involves overcoming key challenges, including reaching temperatures exceeding 100 million degrees Celsius, maintaining stable long-term operation, and ensuring precise control of the fusion process.
“A fusion device must achieve stable operation at high efficiency for thousands of seconds to enable the self-sustaining circulation of plasma, which is essential for the continuous power generation of future fusion plants,” said SONG Yuntao, ASIPP director and also vice president of HFIPS. He said that the recent record is monumental, marking a critical step toward realizing a functional fusion reactor.
According to GONG Xianzu, head of the EAST Physics and Experimental Operations division, several systems of the EAST device have been upgraded since the last round of experiments. For example, the heating system, which previously operated at the equivalent power of nearly 70,000 household microwave ovens, has now doubled its power output while maintaining stability and continuity.
Since its inception in 2006, EAST has served as an open testing platform for both Chinese and international scientists to conduct fusion-related experiments and research.
China officially joined the International Thermonuclear Experimental Reactor (ITER) program in 2006 as its seventh member. Under the agreement, China is responsible for approximately 9 percent of the project’s construction and operation, with ASIPP serving as the primary institution for the Chinese mission.
ITER, currently under construction in southern France, is set to become the world’s largest magnetic confinement plasma physics experiment and the largest experimental tokamak nuclear fusion reactor upon completion.
In recent years, EAST has consistently achieved groundbreaking advancements in high-confinement mode, a fundamental operational mode for experimental fusion reactors like ITER and the future China Fusion Engineering Test Reactor (CFETR). These accomplishments provide invaluable insights and references for the global development of fusion reactors.
“We hope to expand international collaboration via EAST and bring fusion energy into practical use for humanity,” said SONG.
In Hefei, Anhui Province, China, where EAST is loacated [sic], a new generation of experimental fusion research facilities is currently under construction. These facilities aim to further accelerate the development and application of fusion energy.
I always feel a little less confident about the information when there are mistakes. Three typos in the same press release? Maybe someone forgot to give it a final once over?
Successfully harnessing the power of fusion energy could lead to cleaner and safer energy for all – and contribute substantially to combatting [UK spelling] the climate crisis. Towards this goal, Type One Energy has published a comprehensive, self-consistent, and robust physics basis for a practical fusion pilot power plant.
This groundbreaking research is presented in a series of six peer-reviewed scientific papers in a special issue of the prestigious Journal of Plasma Physics (JPP), published by Cambridge University Press.
The articles serve as the foundation for the company’s first fusion power plant project, which Type One Energy is developing with the Tennessee Valley Authority utility in the United States.
Alex Schekochihin, Professor of Theoretical Physics at the University of Oxford and Editor of the JPP, spoke with enthusiasm about this development:
“JPP is very proud to provide a platform for rigorous peer review and publication of the papers presenting the physics basis of the Infinity Two stellarator — an innovative and ground-breaking addition to the expanding family of proposed fusion power plant designs.
“Fusion science and technology are experiencing a period of very rapid development, driven by both public and private enthusiasm for fusion power. In this environment of creative and entrepreneurial ferment, it is crucial that new ideas and designs are both publicly shared and thoroughly scrutinised by the scientific community — Type One Energy and JPP are setting the gold standard for how this is done (as we did with Commonwealth Fusion Systems 5 years ago for their SPARC physics basis).”
The new physics design basis for the pilot power plant is a robust effort to consider realistically the complex relationship between challenging, competing requirements that all need to function together for fusion energy to be possible.
This new physics solution also builds on the operating characteristics of high-performing stellarator fusion technology – a stellarator being a machine that uses complex, helical magnetic fields to confine the plasma, thereby enabling scientists to control it and create suitable conditions for fusion. This technology is already being used with success on the world’s largest research stellarator, the Wendelstein 7-X, located in Germany, but the challenge embraced by Type One Energy’s new design is how to scale it up to a pilot plant.
Building the future of energy
Functional fusion technology could offer limitless clean energy. As global energy demands increase and energy security is front of mind, too, this new physics design basis comes at an excellent time.
Christofer Mowry, CEO of Type One Energy, is cognisant of the landmark nature of his company’s achievement and proud of its strong, real-world foundations.
“The physics basis for our new fusion power plant is grounded in Type One Energy’s expert knowledge about reliable, economic, electrical generation for the power grid. We have an organisation that understands this isn’t only about designing a science project.”
This research was developed collaboratively between Type One Energy and a broad coalition of scientists from national laboratories and universities around the world. Collaborating organisations included the US Department of Energy, for using their supercomputers, such as the exascale Frontier machine at Oak Ridge National Laboratory, to perform its physics simulations.
While commercial fusion energy has yet to move from theory into practice, this new research marks an important and promising milestone. Clean and abundant energy may yet become reality.
This is not directly related to fusion energy, so, you might want to skip this section.

I wonder if anyone argued for a change of name given how charged the US history associated with ‘Bull Run’ is, from the the First Battle of Bull Run Wikipedia entry, Note: Links have been removed,
The First Battle of Bull Run, called the Battle of First Manassas[1] by Confederate forces, was the first major battle of the American Civil War. The battle was fought on July 21, 1861, in Prince William County, Virginia, just north of what is now the city of Manassas and about thirty miles west-southwest of Washington, D.C. The Union Army was slow in positioning themselves, allowing Confederate reinforcements time to arrive by rail. Each side had about 18,000 poorly trained and poorly led troops. The battle was a Confederate victory and was followed by a disorganized post-battle retreat of the Union forces.
…
A Confederate victory the first time and the second time (Second Battle of Bull Run Wikipedia entry)? For anyone unfamiliar with the history, the US Civil War was fought from 1861 to 1865 between Union and Confederate forces. The Confederate states had seceded from the union (US) and were fighting to retain their slavery-based economy and they lost the war.
Had anyone consulted me I would have advised changing the name from Bull Run to some thing less charged (pun noted) to host your prototype fusion energy pilot plant.
Back to the usual programme.
Type One Energy
Type One Energy issued a March 27, 2025 news release about the special issue of the Journal of Plasma Physics (JPP), Note 1: Some of this redundant; Note 2: Links have been removed,
Type One Energy announced today publication of the world’s first comprehensive, self-consistent, and robust physics basis, with conservative design margins, for a practical fusion pilot power plant. This physics basis is presented in a series of seven peer-reviewed scientific papers in a special issue of the prestigious Journal of Plasma Physics (JPP). They serve as the foundation for the company’s first Infinity Two stellarator fusion power plant project, which Type One Energy is developing for the Tennessee Valley Authority (TVA) utility in the U.S.
The Infinity Two fusion pilot power plant physics design basis realistically considers, for the first time, the complex relationship between competing requirements for plasma performance, power plant startup, construction logistics, reliability, and economics utilizing actual power plant operating experience. This Infinity Two baseline physics solution makes use of the inherently favorable operating characteristics of highly optimized stellarator fusion technology using modular superconducting magnets, as was so successfully proven on the W7-X science machine in Germany.
“Why are we the first private fusion company with an agreement to develop a potential fusion power plant project for an energy utility? Because we have a design anchored in reality,” said Christofer Mowry, CEO of Type One Energy. “The physics basis for Infinity Two is grounded in the knowledge of what is required for application to, and performance in, the demanding environment of reliable electrical generation for the power grid. We have an organization that understands this isn’t about designing a science project.”
Led by Chris Hegna, widely recognized as a leading theorist in modern stellarators, Type One Energy performed high-fidelity computational plasma physics analyses to substantially reduce the risk of meeting Infinity Two power plant functional and performance requirements. This unique and transformational achievement is the result of a global development program led by the Type One Energy plasma physics and stellarator engineering organization, with significant contributions from a broad coalition of scientists from national laboratories and universities around the world. The company made use of a spectrum of high-performance computing facilities, including access to the highest-performance U.S. Department of Energy supercomputers such as the exascale Frontier machine at Oak Ridge National Laboratory (ORNL), to perform its stellarator physics simulations.
“We committed to this ambitious fusion commercialization milestone two years ago and today we delivered,” said John Canik, Chief Science and Engineering Officer for Type One Energy. “The team was able to efficiently develop deep plasma physics insights to inform the design of our Infinity Two stellarator, by taking advantage of our access to high performance computing resources. This enabled the Type One Energy team to demonstrate a realistic, integrated stellarator design that moves far beyond conventional thinking and concepts derived from more limited modeling capabilities.”
The consistent and robust physics solution for Infinity Two results in a deuterium-tritium (D-T) fueled, burning plasma stellarator with 800 MW of fusion power and delivers a nominal 350 MWe to the power grid. It is characterized by fusion plasma with resilient and stable behavior across a broad range of operating conditions, very low heat loss due to turbulent transport, as well as tolerable direct energy losses to the stellarator first wall. The Infinity Two stellarator has sufficient room for both adequately sized island divertors to exhaust helium ash and a blanket which provides appropriate shielding and tritium breeding. Type One Energy has high confidence that this essential physics solution provides a good baseline stellarator configuration for the Infinity Two fusion pilot power plant.
“The articles in this issue [of JPP] represent an important step towards a fusion reactor based on the stellarator concept. Thanks to decades of experiments and theoretical research, much of the latter published in JPP, it has become possible to lay out the physics basis for a stellarator power plant in considerable detail,” said Per Helander, head of Stellarator Theory Division at the Max Planck Institute for Plasma Physics. “JPP is very happy to publish this series of papers from Type One Energy, where this has been accomplished in a way that sets new standards for the fidelity and confidence level in this context.”
Important to successful fusion power plant commercialization, this stellarator configuration has enabled Type One Energy to architect a maintenance solution which supports good power plant Capacity Factors (CF) and associated Levelized Cost of Electricity (LCOE). It also supports favorable regulatory requirements for component manufacturing and power plant construction methods essential to achieving a reasonable Over-Night Cost (ONC) for Infinity Two.

While the company is currently headquartered in Knoxville, Tennessee, it was originally a spinoff company from the University of Wisconsin-Madison according to a March 30, 2023 posting on the university’s College of Engineering website,
Type One Energy, a Middleton, Wisconsin-based fusion energy company with roots in the University of Wisconsin-Madison’s College of Engineering, recently announced its first round of seed funding, raising $29 million from investors. The company has also onboarded a new, highly experienced CEO [Christofer Mowry].
Type One, founded in 2019 by a team of globally recognized fusion scientists and business leaders, is hoping to commercialize stellarator technology over the next decade. Stellarators are a type of fusion reactor that uses powerful magnets to confine ultra-hot streams of plasma in order to create the conditions for fusion reactions. Energy from fusion promises to be clean, safe, renewable power. The company is using advanced manufacturing methods, modern computational physics and high-field superconducting magnets to develop its stellarator through an initiative called FusionDirect.

According to the Type One Energy’s About page, there are four offices with the headquarters in Tennessee,
Madison 316 W Washington Ave. Suite 300 Madison, WI 53703
Boston 299 Washington St. Suites C & E Woburn, MA 01801
Vancouver 1140 West Pender St. Vancouver, BC V6E 4G1
The mention of an office in Vancouver, Canada piqued my curiosity but before getting to that, I’m going to include some informative excerpts about nuclear energy (both fission and fusion) from this August 31, 2023 article written by Tina Tosukhowong on behalf of TDK Ventures, which was posted on Medium,
Fusion power is the key to the energy transformation that humanity needs to drive decarbonization, clean, and baseload energy production that is inherently fail-safe, with no risk of long-lived radioactive waste, while also delivering on ever-growing energy-consumption demands at the global scale. Fusion is hard and requires exceptional conditions for sustained reaction (which is part of what makes it so safe), which has long served as a deterrent for technical maturation and industrial viability. …
…
The current reality of our world is monumental fossil-fuel dependence. This, coupled with unprecedented levels of energy demand has resulted in the over 136,700 TWh (that’s 10¹²) of energy consumed via fossil fuels annually [1]. Chief repercussion among the many consequences of this dependence is the now very looming threat of climate catastrophe, which will soon be irreversible if global temperature rise is not abated and held to within 1.5 °C of pre-industrial levels. To do so, the nearly 40 gigatons of CO2 emissions generated each year must be steadily reduced and eventually mitigated entirely [2]. A fundamental shift in how power is generated globally is the only way forward. Humanity needs an energy transformation — the right energy transformation.
Alternative energy-generation techniques, such as wind, solar, geothermal, and hydroelectric approaches have all made excellent strides, and indeed in just the United States electricity generated by renewable methods doubled from 10 to 20% of total between 2010 and 2020 [3–4]. These numbers are incredibly encouraging and give significant credence in the journey to net-zero emission energy generation. However, while these standard renewable approaches should be championed, wind and solar are intermittent and require a large amount of land to deploy, while geothermal and hydroelectric are not available in every geography.
By far the most viable candidates for continuous clean energy generation to replace coal-fired power plants are nuclear-driven technologies, i.e. nuclear fission or nuclear fusion. Nuclear fission has been a proven effective method ever since it was first demonstrated almost 80 years ago underneath the University of Chicago football Stadium by Nobel Laureate Enrico Fermi [5]. Heavier atomic elements, in most cases Uranium-235, are exposed to and bombarded by neutrons. This causes the Uranium to split resulting in two slightly less-heavy elements (like Barium and Krypton). This in turn causes energy to be released and more neutrons to be ejected and bombard other nearby Uranium-235, at which point the process cascades into a chain reaction. The released energy (heat) is utilized in the same way coal is burned in a traditional power plant, being subsequently used to generate electricity usually via the creation of steam to drive a turbine [6]. While already having reached viable commercial maturity, fission carries inherent and nontrivial safety concerns. An unhampered chain reaction can quickly lead to meltdown with disastrous consequences, and, even when properly managed, the end reaction does generate radioactive waste whose half-life can last hundreds of thousands of years.
Figure 1. Breakdown of a nuclear fission reaction [6]. Incident neutron bombards a fissile heavy element, splitting it and release energy and more nuclei setting off a chain reaction.
Especially given modernization efforts and meteoric gains in safety (thanks to advents in material science like ceramic coatings), fission will continue to be a critical piece to better, greener energy transformation. However, in extending our vision to an even brighter future with no such concerns — carbon emissions or safety — nuclear fusion is humanity’s silver bullet. Instead of breaking down atoms leading to a chain reaction, fusion is the combining of atoms (usually isotopes of Hydrogen) into heavier elements which also results in energy release / heat generation [7]. Like fission, fusion can be designed to be a continuous energy source that can serve as a permanent backbone to the power grid. It is extremely energy dense, with 1 kg of fusion fuel producing the same amount of energy as 1,000,000 kg of coal, and it is inherently fail-safe with no long-term radioactive waste.
…
As a concept, if fusion is a silver bullet to answer humanity’s energy transformation needs, then why haven’t we done so already? The appeal seems so obvious, what’s the hold up? Simply put, nuclear fusion is hard for the very same reason the process is inherently safe. Atoms in the process must have enough energy to overcome electrostatic repulsive forces between the two positive charges of their nuclei to fuse. The key figure of merit to evaluate fusion is the so-called “Lawson Triple Product.” Essentially, this means in order to generate energy by fusion more than the rate of energy oss to the environment, the nuclei must be very close together (as represented by n — the plasma density), kept at a high enough temperature (as represented by T — temperature), and for long enough time to sustain fusion (as represented by τ — the confinement time). The triple product required to achieve fusion “ignition” (the state where the rate of energy production is higher than the rate of loss) depends on the fuel type and occurs within a plasma state. A deuterium and tritium (D-T) system has the lowest Lawson Triple product requirement, where fusion can achieve a viable threshold for ignition when the density of the fuel atoms, n, multiplied by the fuel temperature, T, multiplied by the confinement time, τ, is greater than 5×10²¹ (nTτ > 5×10²¹ keV-s/m³) [8–9]. For context, the temperature alone in this scenario must be higher than 100-million degrees Celsius.
Figure 2. (Left) Conceptual illustration of a fusion reaction with Deuterium (²H) and Tritium (³H) forming an Alpha particle (⁴He) and free neutron along with energy released as heat (Right). To initiate fusion, repelling electrostatic charge must be overcome via conditions meeting the minimum Lawson Triple Product threshold

Tosukhowong’s August 31, 2023 article provides a good overview keeping in mind that it is slanted to justify TDK’s investment in Type One Energy.
Why a Vancouver, Canada office?
As for Type One Energy’s Vancouver (British Columbia, Canada) connection, I was reminded of General Fusion, a local fusion energy company while speculating about the connection. First speculative question: could Type One Energy’s presence in Canada allow it to access Canadian government funds for its research? Second speculative question: do they want to have access to people who might hesitate to move to the US or might want to move out of the US but would move to Canada?
The US is currently in an unstable state as suggested in this April 3, 2025 opinion piece by Les Leyne for vancouverisawsome.com
Les Leyne: Trump’s incoherence makes responding to tariff wall tricky
Trump’s announcement was so incoherent that much of the rest of the world had to scramble to grasp even the basic details
B.C. officials were guarded Wednesday [April 2, 2025] about the impact on Canada of the tariff wall U.S. President Donald Trump erected around the U.S., but it appears it could have been worse.
Trump’s announcement was so incoherent that much of the rest of the world had to scramble to grasp even the basic details. So cabinet ministers begged for more time to check the impacts.
“It’s still very uncertain,” said Housing Minister Ravi Kahlon, who chairs the “war room” committee responsible for countering tariff threats. “It’s hard to make sense from President Trump’s speech.” [emphasis mine]
Kahlon said the challenge is that tariff policies change hour by hour, “and anything can happen.”
…
On April 2, 2025 US President Donald Trump announced tariffs (then paused some of the tariffs on April 9, 2025) and some of the targets seemed a bit odd, from an April 2, 2025 article by Alex Galbraith for salon.com, Note: Links have been removed,
“Trade war with penguins”: Trump places 10% tariff on uninhabited Antarctic islands
Planned tariffs shared by the White House included a 10% duty on imports from the barren Heard and McDonald Islands
For once in his life, Donald Trump underpromised and over-delivered.
The president announced a 10% duty on all imports on Wednesday [April 2, 2025], along with a raft of reciprocal tariffs on U.S. trading partners. An extensive graphic released by the White House showed how far Trump was willing to take his tit-for-tat trade war, including a shocking levy of 10% on all imports from the Heard and McDonald Islands.
If you haven’t heard of this powerhouse of global trade and territory of Australia, you aren’t alone. Few have outside of Antarctic researchers and seals. These extremely remote islands about 1,000 miles north of Antarctica consist mostly of barren tundra. They’re also entirely uninhabited.
The news that we were starting a trade war with penguins spread quickly after Trump’s announcement. …
U.S. stock futures crumbled following the news of Trump’s widespread tariffs. Dow futures fell by nearly 1,000 points while NASDAQ and S&P futures fell by 3 to 4%. American companies’ stock values rapidly tumbled after the announcement, with large retail importers seeing significant losses. …
No word from the penguins about the ‘pause’. I’m assuming Donald Trump’s next book will be titled, “The art of negotiating trade deals with penguins.” Can’t wait to read it.
(Perhaps someone should tell him there are no penguins in the Arctic so he can’t bypass Canadians or Greenlanders to make a deal.)
Now for the local story.
General Fusion
There’ve been two recent developments at General Fusion. Most recently, an April 2, 2025 General Fusion news release announces a new hire, Note: Links have been removed,
Bob Smith is joining General Fusion as a strategic advisor. Smith brings more than 35 years of experience developing, scaling, and launching world-changing technologies, including spearheading new products and innovation in the aerospace industry at United Space Alliance, Sandia Labs, and Honeywell before serving as CEO of Blue Origin. He joins General Fusion as the company’s Lawson Machine 26 (LM26) fusion demonstration begins operations and progresses toward transformative technical milestones on the path to commercialization.
“I’ve been watching the fusion energy industry closely for my entire career. Fusion is the last energy source humanity will ever need, and I believe its impact as a zero-carbon energy source will transform the global energy supply at the time needed to fight the worst consequences of climate change,” said Smith. “I am thrilled to work with General Fusion. Their novel approach has inherent and distinctive benefits for the generation of commercially competitive fusion power. It’s exciting to join at a time when the team is about to demonstrate the fundamental physics behind their system and move to scaling up to a pilot plant.”
The LM26 program marks a significant step towards commercialization, as the company’s unique Magnetized Target Fusion (MTF) approach makes the path to powering the grid with fusion energy more straightforward than other technologies—because it practically addresses barriers to fusion commercialization, such as neutron material degradation, sustainable fuel production, and efficient energy extraction. As a strategic advisor, Smith will leverage his experience advancing game-changing technologies to help guide General Fusion’s technology development and strategic growth.
“Bob’s insights and experience will be invaluable as we execute the LM26 program and look beyond it to propel our practical technology to powering the grid by the mid-2030s,” said Greg Twinney, CEO, General Fusion. “We are grateful for his commitment of his in-demand time and expertise to our mission and look forward to working together to make fusion power a reality!”

Quick Facts:
Fusion energy is the ultimate clean energy solution—it is the energy source that powers the sun and stars. Fusion is the process by which two light nuclei merge to form a heavier one, producing a massive amount of energy.
General Fusion’s Magnetized Target Fusion (MTF) technology is designed to scale for cost-efficient power plants. It uses mechanical compression to create fusion conditions in short pulses, eliminating the need for expensive lasers or superconducting magnets. An MTF power plant is designed to produce its own fuel and inherently includes a method to extract the energy and put it to work.
Lawson Machine 26 (LM26) is a world-first Magnetized Target Fusion demonstration. Launched, designed, and assembled in just 16 months, the machine is now forming magnetized plasmas regularly at 50 per cent commercial scale. It is advancing towards a series of results that will demonstrate MTF in a commercially relevant way: 10 million degrees Celsius (1 keV), 100 million degrees Celsius (10 keV), and scientific breakeven equivalent (100% Lawson).
About General Fusion General Fusion is pursuing a fast and practical approach to commercial fusion energy and is headquartered in Richmond, Canada. The company was established in 2002 and is funded by a global syndicate of leading energy venture capital firms, industry leaders, and technology pioneers. Learn more at www.generalfusion.com.

Bob Smith and Blue Origin: things did not go well
Sometimes you end up in a job and things do not work out well and that seems to have been the case at Blue Origin according to a September 25, 2023 article by Eric Berger for Ars Tecnica,
After six years of running Blue Origin, Bob Smith announced in a company-wide email on Monday that he will be “stepping aside” as chief executive of the space company founded by Jeff Bezos.
“It has been my privilege to be part of this great team, and I am confident that Blue Origin’s greatest achievements are still ahead of us,” Smith wrote in an email. “We’ve rapidly scaled this company from its prototyping and research roots to a large, prominent space business.”
Shortly after Smith’s email, a Blue Origin spokesperson said the company’s new chief executive will be Dave Limp, who stepped down as Amazon’s vice president of devices and services last month.
…
To put things politely, Smith has had a rocky tenure as Blue Origin’s chief executive. After being personally vetted and hired by Bezos, Smith took over from Rob Meyerson in 2017. The Honeywell engineer was given a mandate to transform Blue Origin into a large and profitable space business.
He did succeed in growing Blue Origin. The company had about 1,500 employees when Smith arrived, and the company now employs nearly 11,000 people. But he has been significantly late on a number of key programs, including the BE-4 rocket engine and the New Glenn rocket.
As a space reporter, I have spoken with dozens of current and former Blue Origin employees, and virtually none of them have had anything positive to say about Smith’s tenure as chief executive. I asked one current employee about the hiring of Limp on Monday afternoon, and their response was, “Anything is better than Bob.”
Although it is very far from an exact barometer, Smith has received consistently low ratings on Glassdoor for his performance as chief executive of Blue Origin. And two years ago, a group of current and former Blue Origin employees wrote a blistering letter about the company under Smith. “In our experience, Blue Origin’s culture sits on a foundation that ignores the plight of our planet, turns a blind eye to sexism, is not sufficiently attuned to safety concerns, and silences those who seek to correct wrongs,” the essay authors wrote.
With any corporate culture, there will be growing pains, of course. But Smith brought a traditional aerospace mindset into a company that had hitherto been guided by a new space vision, leading to a high turnover rate. And Blue Origin remains significantly underwater, financially. It is likely that Bezos is still providing about $2 billion a year to support the company’s cash needs.
Crucially, as Blue Origin meandered under Smith’s tenure, SpaceX soared, launching hundreds of rockets and thousands of satellites. Smith, clearly, was not the leader Blue Origin needed to make the company more competitive with SpaceX in launch and other spaceflight activities. It became something of a parlor game in the space industry to guess when Bezos would finally get around to firing Smith.
…
On the technical front, a March 27, 2025 General Fusion news release announces “Peer-reviewed publication confirms General Fusion achieved plasma energy confinement time required for its LM26 large-scale fusion machine,” Note: Links have been removed,
New results published in Nuclear Fusionconfirm General Fusion successfully created magnetized plasmas that achieved energy confinement times exceeding 10 milliseconds. The published energy confinement time results were achieved on General Fusion’s PI3 plasma injector — the world’s largest and most powerful plasma injector of its kind. Commissioned in 2017, PI3 formed approximately 20,000 plasmas in a machine of 50 per cent commercial scale. The plasma injector is now integrated into General Fusion’s Lawson Machine 26 (LM26) — a world-first Magnetized Target Fusion demonstration tracking toward game-changing technical milestones that will advance the company’s ultimate mission: generating zero-carbon fusion energy for the grid in the next decade.
The 10-millisecond energy confinement time is the duration required to compress plasmas in LM26 to achieve key temperature thresholds of 1 keV, 10 keV, and, ultimately, scientific breakeven equivalent (100% Lawson). These results were imperative to de-risking LM26. The demonstration machine is now forming plasmas regularly, and the company is optimizing its plasma performance in preparation for compressing plasmas to create fusion and heating from compression.
Key Findings:
The plasma injector now integrated into General Fusion’s LM26 achieved energy confinement times exceeding 10 milliseconds, the pre-compression confinement time required for LM26’s targeted technical milestones. These results were achieved without requiring active magnetic stabilization or auxiliary heating. This means the results were achieved without superconducting magnets, demonstrating the company’s cost-effective approach.
The plasma’s energy confinement time improved when the plasma injector vessel was coated with natural lithium. A key differentiator in General Fusion’s commercial approach is its use of a liquid lithium wall to compress plasmas during compression. In addition to the confinement time advantages shown in this paper, the liquid lithium wall will also protect a commercial MTF machine from neutron damage, enable the machine to breed its own fuel, and provide an efficient method for extracting energy from the machine.
The maximum energy confinement time achieved by PI3 was approximately 12 milliseconds. The machine’s maximum plasma density was approximately 6×1019 m-3, and maximum plasma temperatures exceeded 400 eV. These strong pre-compression results support LM26’s transformative targets.
Quotes:
“LM26 is designed to achieve a series of results that will demonstrate MTF in a commercially relevant way. Following LM26’s results, our unique approach makes the path to powering the grid with fusion energy more straightforward than other technologies because we have front-loaded the work to address the barriers to commercialization.”
Dr. Michel Laberge Founder and Chief Science Officer
“For over 16 years, I have worked hand in hand with Michel to advance General Fusion’s practical technology. This company is entrepreneurial at its core. We pride ourselves on building real machines that get results that matter, and I’m thrilled to have the achievements recognized in Nuclear Fusion.”
Mike Donaldson Senior Vice President, Technology Development
For anyone curious about General Fusion, I have a brief overview and history of the company and their particular approach to fusion energy in my February 6, 2024 posting (scroll down to ‘The Canadians’).
“Geist’s handmade robots made movements as simple as a ping-pong table flapping or coiling up to shoot, but the contact microphones and sound processing documented a percussive, electro, mini symphony.” – Austin Chronicle
There’s mystery in Geist’s music. It’s heady, ASMR-infused dance music — there’s something special happening here, but it’s not immediately clear what.” –– Engadget
“For Geist, the instruments represent not just a new way to make music, but a new way to experience it. The instruments each have a visual component, which makes it possible to watch the sounds as Geist creates them.” – Wired
The performance is fascinating and bewildering, but the music itself provokes one to want to dance in a dimly lit nightclub.” – MixMag
“It doesn’t get geekier than this” – New York Times.
“These robots play electrifying techno music.”– CNET
German sonic artist Moritz Simon Geist will showcase his latest work “Don’t Look At Me” at the Central Presbyterian Church March 15th. With his new robotic instrument Geist is presenting a contemplative ambient performance around the themes attention economy, spatial sound and sine waves. “Don’t Look at Me” was developed as an interactive installation in 2023 in South Korea and uses resonator tubes, light, and vibrato elements to create a fascinating ever-changing soundscape. For the SXSW event, Geist is showcasing his latest compositions with this instrument.
Moritz is returning to SXSW 2024 with a handful of performances and robotic interventions. His works and performances revolve around the questions: How do machines, algorithms and humans interact? How can we find a playful way to interact with non-human music players? And can robots play techno?
Moritz and his team have been developing sound machines and kinetic installations for more than 10 years already, and his works and performances have been shown at festivals and stages around the world. For this SXSW, Moritz is bringing both performances for several techno shows as well as a contemplative ambient show at the Central Presbyterian Church on March 15th [2024]. Here he will present compositions for his latest work “Don’t Look At Me”.
Geist is well known for his performances and self-developed instruments using robots and mechanics as the main sound source. His works have been shown internationally and have been awarded numerous awards in the last years.
Of his return to SXSW, Moritz says, “SXSW 2024 is only the second time I’m playing ‘Don’t Look at Me’ with my new robotic instrument! Playing with a new instrument this complex is always like this first walk outside with a toddler: You never know where you end up: manic laughter at the playground or existential crying in the supermarket.” Regarding his ongoing fascination with machines as instruments, Moritz muses, “When I was younger, I played in a punk rock band, but at some point, I got really annoyed by my fellow musicians, so I swore to myself that I would never play with human musicians again. Jokes aside, I think robotics is a wonderful tool to give a body back to the normally electronically generated sound of techno. The main reason why I’m using robotics as a musical instrument is that the computer is, in my opinion, not the best tool for creating electronic sounds.”

The three speakers being highlighted here are not focused on artificial intelligence/robotics and have nothing in common with each other (topic wise).
First up, Bill Ackman, a very, very wealthy man, has a messy backstory. Here’s the short description followed by the long one,
Bill Ackman
Founder and CEO, Pershing Square Capital Management
TALK TOPIC
The activist investor playbook (in conversation with Alison Taylor)
Bill Ackman is founder and CEO of the hedge fund Pershing Square Capital Management and a storied activist investor. He is the chairman of Howard Hughes Holdings, a real estate development and management company based in Texas, and a member of the board of Universal Music Group. He is also the co-trustee of The Pershing Square Foundation, a family foundation supporting those tackling important social issues worldwide. At TED2024, Ackman will be interviewed by business professor Alison Taylor.
Mr. Ackman is not entirely self-made, from his Wikipedia entry, Note: Links have been removed,
…
Ackman was raised in Chappaqua, New York, the son of Ronnie I. (née Posner) and Lawrence David Ackman, the former chairman of a New York real estate financing firm, Ackman-Ziff Real Estate Group. [emphases mine] [10][11][12] He is of Ashkenazi Jewish descent.[13][14][15] In 1988, he received a Bachelor of Arts degree magna cum laude in social studies from Harvard College. His thesis was titled Scaling the Ivy Wall: The Jewish and Asian American Experience in Harvard Admissions.[16] In 1992, he received a Master of Business Administration degree from Harvard Business School.[17]
As for the messiness, there’s this from from his Wikipedia entry, Note 1: Links have been removed, Note 2: All emphases are mine,
…
In October 2023, following the onset of the 2023 Israel–Hamas war after the October 7 attack, several Harvard undergraduate student groups signed a letter condemning the Israeli state. The statement held the “Israeli regime entirely responsible for all unfolding violence,” declared that millions of Palestinians in Gaza have been “forced to live in an open-air prison,” and called on Harvard to “take action to stop the ongoing annihilation of Palestinians.”
In response, Ackman called for the publication of the names of all students involved in signing the letter so that he could ensure his company and others do not “inadvertently hire” any of the signatories. Ackman posted, “One should not be able to hide behind a corporate shield when issuing statements supporting the actions of terrorists,” and the names “should be made public so their views are publicly known”.[83] Ackman’s stance was supported by other CEOs such as Jonathan Neman, David Duel and Jake Wurzak.[84] Former Harvard president Lawrence Summers, though agreeing with Ackman on the need to look at employees’ political views, called Ackman’s request for a list of names “the stuff of Joe McCarthy”.[85]
In November 2023, Ackman defended Elon Musk after the latter expressed agreement with a user who asserted that “Jewish communities” supported “hordes of minorities flooding their country” and pushed “dialectical hatred against whites”, describing it as “shoot from the hip commentary”.[86][87]
Ackman also engaged in a campaign to remove Claudine Gay from her position as Harvard’s president. He argued that her response to antisemitism was insufficient and amplified allegations by conservative media that she engaged in plagiarism.[88][89]
On January 3, 2024, Business Insider published an article alleging that Ackman’s wife, Neri Oxman*, plagiarized portions of her dissertation. A day after the article’s publication, Oxman apologized for plagiarizing portions of her dissertation.[90][91]Ackman, in response to the article, pledged to conduct a plagiarism review of all MIT [Massachusetts Institute of Technology] faculty, including MIT’s president, Sally Kornbluth, who, alongside Gay, attended a congressional hearing on antisemitism in higher education.[90]
…
In 2018, Ackman became engaged to Neri Oxman.[94] In January 2019, Oxman and Ackman married at the Central Synagogue in Manhattan,[13] and they had their first child together in spring 2019.[95] In August 2019, Ackman wrote to MIT Media Lab director Joi Ito to discourage him from mentioning Oxman when discussing convicted sex offender Jeffrey Epstein, who had donated $125,000 to Oxman’s lab.[96]
…
*There are more complications where Neri Oxman is concerned. She is an Israeli-American who came to the US in 2005 where she commenced PhD studies at MIT. After graduation she became a professor at MIT, a position she has left to found Oxman Architects in 2020. Despite the company name, the business seems more focused on art installations and experimental work. (sourced from Oxman’s Wikipedia entry)*
I wonder how Mr. Ackman characterizes the difference between activism and actions, which result in the destruction of other people’s careers because you disagree with them.
Ackman’s interviewer, Alison Taylor is an interesting choice given that she is a business professor at New York University’s Stern School of Business and author of a February 6, 2024 article (Corporate Advocacy in a Time of Social Outrage; Businesses can’t weigh in on every issue that employees care about. But they can create a culture of open dialogue and ethical transparency [emphasis mine]) for the Harvard Business Review, The article is excerpted from Taylor’s book, “Higher Ground: How Business Can Do the Right Thing in a Turbulent World,” published by Harvard Business Review Press, Feb. 13 2024.
This talk looks like an attempt to rehabilitate Mr. Ackman’s reputation while giving Ms. Taylor publicity for her newly published book in an environment where neither is likely to be strongly challenged.
The two speakers I’m most excited about are Tammy Ma, fusion physicist, and Brian Stokes Mitchell, actor and singer.
As there is a local company known as General Fusion, the topic of fusion energy has been covered here a number of times including a relevant to Ms. Ma’s TED appearance December 13, 2022 posting, “US announces fusion energy breakthrough.”
Tammy Ma is the lead for the Inertial Fusion Energy Initiative at Lawrence Livermore National Laboratory, where she creates miniature stars in order to develop ways to harness their power as a clean, limitless energy source for the future. She was a member of the team at the National Ignition Facility that achieved fusion ignition in December 2022 — a reaction that, for the first time in history, released more energy than it consumed. [emphasis mine] A fellow of the American Physical Society, she serves on the Fusion Energy Sciences Advisory Committee, advising the US Department of Energy’s Office of Science on issues related to fusion energy and plasma research.
Brian Stokes Mitchell is a Tony-winning actor, singer and music producer. A veteran of 11 Broadway shows and a member of the Theatre Hall of Fame, he has performed iconic roles including Frasier’s snarky upstairs neighbor Cam, Hillary’s bungie-jumping boyfriend on the Fresh Prince of Bel-Air, The Prince of Egypt (singing “Through Heaven’s Eyes”) and, most recently, Stanley Townsend in the 2024 feature film Shirley with Regina King. He has performed twice at the White House, serves on the board of Americans for the Arts and is one of the founding members of Black Theatre United.
Stokes Mitchell performed at the Library of Congress Gershwin Prize for Popular Song ceremony in 2017 when Tony Bennett was the honoree. The performances were top notch but something happened when Stokes Mitchell took the stage for his first number. The audience was electrified as was every performer who came after him, some of them giving their second performance of the evening. There is no guarantee that Mr. Stoke Mitchell can do that at his 2024 TED talk but that is the blessing and the curse of live performances.
Andrew Paul’s December 4, 2023 article for Popular Science attempts to give readers a sense of the scale and this is one of those times when words are better than pictures, Note: Links have been removed,
Japan and the European Union have officially inaugurated testing at the world’s largest experimental nuclear fusion plant. Located roughly 85 miles north of Tokyo, the six-story, JT-60SA “tokamak” facility heats plasma to 200 million degrees Celsius (around 360 million Fahrenheit) within its circular, magnetically insulated reactor. Although JT-60SA first powered up during a test run back in October [2023], the partner governments’ December 1 announcement marks the official start of operations at the world’s biggest fusion center, reaffirming a “long-standing cooperation in the field of fusion energy.”
The tokamak—an acronym of the Russian-language designation of “toroidal chamber with magnetic coils”—has led researchers’ push towards achieving the “Holy Grail” of sustainable green energy production for decades. …
Speaking at the inauguration event, EU energy commissioner Kadri Simson referred to the JT-60SA as “the most advanced tokamak in the world,” representing “a milestone for fusion history.”
…
But even if such a revolutionary milestone is crossed, it likely won’t be at JT-60SA. Along with its still-in-construction sibling, the International Thermonuclear Experimental Reactor (ITER) in Europe, the projects are intended solely to demonstrate scalable fusion’s feasibility. Current hopes estimate ITER’s operational start for sometime in 2025, although the undertaking has been fraught with financial, logistical, and construction issues since its groundbreaking back in 2011.
…
See what I mean about a picture not really conveying the scale,
Until ITER turns on, Japan’s JT-60SA fusion reactor will be the largest in the world.National Institutes for Quantum Science and Technology
Dennis Normile’s October 31, 2023 article for Science magazine describes the facility’s (Japan’s JT-60SA fusion reactor) test run and future implications for the EU’s ITER project,
The long trek toward practical fusion energy passed a milestone last week when the world’s newest and largest fusion reactor fired up. Japan’s JT-60SA uses magnetic fields from superconducting coils to contain a blazingly hot cloud of ionized gas, or plasma, within a doughnut-shaped vacuum vessel, in hope of coaxing hydrogen nuclei to fuse and release energy. The four-story-high machine is designed to hold a plasma heated to 200 million degrees Celsius for about 100 seconds, far longer than previous large tokamaks.
Last week’s achievement “proves to the world that the machine fulfills its basic function,” says Sam Davis, a project manager at Fusion for Energy, an EU organization working with Japan’s National Institutes for Quantum Science and Technology (QST) on JT-60SA and related programs. It will take another 2 years before JT-60SA produces the long-lasting plasmas needed for meaningful physics experiments, says Hiroshi Shirai, leader of the project for QST.
JT-60SA will also help ITER, the mammoth international fusion reactor under construction in France that’s intended to demonstrate how fusion can generate more energy than goes into producing it. ITER will rely on technologies and operating know-how that JT-60SA will test.
Japan got to host JT-60SA and two other small fusion research facilities as a consolation prize for agreeing to let ITER go to France. …
As Normile notes, the ITER project has had a long and rocky road so far.
The Canadians
As it turns out, there’s a company in British Columbia, Canada that is also on the road to fusion energy. Not so imaginatively, it’s called General Fusion but it has a different approach to developing this ‘clean energy’. (See my October 28, 2022 posting, “Overview of fusion energy scene,” which includes information about the international scene and some of the approaches, including General Fusion’s, to developing the technology and my October 11, 2023 posting offers an update to the General Fusion situation.) Since my October 2023 posting, there have been a few developments at General Fusion.
This December 4, 2023 General Fusion news release celebrates a new infusion of cash from the Canadian government and take special note of the first item in the ‘Quick Facts’ of the advantage this technology offers,
Today [December 4, 2023], General Fusion announced that Canada’s Strategic Innovation Fund (SIF) has awarded CA$5 million to support research and development to advance the company’s Magnetized Target Fusion (MTF) demonstration at its Richmond headquarters. Called LM26, this ground-breaking machine will progress major technical milestones required to commercialize zero-carbon fusion power by the early to mid-2030s. The funds are an addition to the existing contribution agreement with SIF, to support the development of General Fusion’s transformational technology.
Fusion energy is the ultimate clean energy solution. It is what powers the sun and stars. It’s the process by which two light nuclei merge to form a heavier one, emitting a massive amount of energy. By 2100, the production and export of the Canadian industry’s fusion energy technology could provide up to $1.26 trillion in economic benefits to Canada. Additionally, fusion could completely offset 600 MT CO2-e emissions, the equivalent of over 160 coal-fired power plants for a single year. When commercialized, a single General Fusion power plant will be designed to provide zero-carbon power to approximately 150,000 Canadian homes, with the ability to be placed close to energy demand at a cost competitive with other energy sources such as coal and natural gas.1
Quotes:
“For more than 20 years, General Fusion has advanced its uniquely practical Magnetized Target Fusion technology and IP at its Canadian headquarters. LM26 will significantly de-risk our commercialization program and puts us on track to bring our game-changing, zero-emissions energy solution to Canada, and the world, in the next decade,” said Greg Twinney, CEO, General Fusion.
“Fusion technology has the potential to completely revolutionize the energy sector by giving us access to an affordable unlimited renewable power source. Since General Fusion is at the forefront of this technology, our decision to keep supporting the company will give us the tools we need to reduce greenhouse gas emissions and reach our climate goals. Our government is proud to invest in this innovative project to drive the creation of hundreds of middle-class jobs and position Canada as a world leader in fusion energy technology,” said The Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry.
“British Columbia has a thriving innovation economy. In August, the B.C. Government announced CA$5 million in provincial support for General Fusion’s homegrown technology, and we’re pleased to see the Federal government has now provided funds to support General Fusion. These investments will help General Fusion as they continue to develop their core technology right here in B.C.,” said Brenda Bailey, B.C. Minister of Jobs, Economic Development and Innovation.
Quick Facts:
*Magnetized Target Fusion uniquely sidesteps challenges to commercialization that other technologies face. The game-changer is a proprietary liquid metal liner in the commercial fusion machine that is mechanically compressed by high-powered pistons. This enables fusion conditions to be created in short pulses rather than creating a sustained reaction. General Fusion’s design does not require large superconducting magnets or an expensive array of lasers.
*LM26 aims to achieve two of the most significant technical milestones required to commercialize fusion energy, targeting fusion conditions of over 100 million degrees Celsius by 2025, and progressing toward scientific breakeven equivalent by 2026.
*LM26’s plasmas will be approximately 50 per cent scale of a commercial fusion machine. It aims to achieve deuterium-tritium breakeven equivalent using deuterium fuel.
*The Canadian government is investing an additional CA$5 million for a total of CA$54.3 million to support the development of General Fusion’s energy technology through the Strategic Innovation Fund program.
*As a result of the government’s ongoing support, General Fusion has advanced its technology, building more than 24 plasma prototypes, filing over 170 patents, and conducting more than 200,000 experiments at its Canadian labs.
General Fusion has published new, peer-reviewed scientific results that validate the company has achieved the smooth, rapid, and symmetric compression of a liquid cavity that is key to the design of a commercial Magnetized Target Fusion power plant. The results, published in one of the foremost scientific journals in fusion, Fusion Engineering and Design [open access paper], validate the performance of General Fusion’s proprietary liquid compression technology for Magnetized Target Fusion and are scalable to a commercial machine.
General Fusion’s Magnetized Target Fusion technology uses mechanical compression of a plasma to achieve fusion conditions. High-speed drivers rapidly power a precisely shaped, symmetrical collapse of a liquid metal cavity that envelopes the plasma. In three years, General Fusion commissioned a prototype of its liquid compression system and completed over 1,000 shots, validating the compression technology. In addition, this scale model of General Fusion’s commercial compression system verified the company’s open-source computational fluid dynamics simulation. The paper confirms General Fusion’s concept for the compression system of a commercial machine.
“General Fusion has proven success scaling individual technologies, creating the pathway to integrate, deploy, and commercialize practical fusion energy,” said Greg Twinney, CEO, General Fusion. “The publication of these results demonstrates General Fusion has the science and engineering capabilities to progress the design of our proprietary liquid compression system to commercialization.”
General Fusion’s approach to compressing plasma to create fusion energy is unique. Its Magnetized Target Fusion technology is designed to address the barriers to commercialization that other fusion technologies still face. The game-changer is the proprietary liquid metal liner in the fusion vessel that is mechanically compressed by high-powered pistons. This allows General Fusion to create fusion conditions in short pulses, rather than creating a sustained reaction, while protecting the machine’s vessel, extracting heat, and re-breeding fuel.
Today [January 11, 2024] at its Canadian labs, General Fusion is building a ground-breaking Magnetized Target Fusion demonstration called Lawson Machine 26 (LM26). Designed to reach fusion conditions of over 100 million degrees Celsius by 2025 and progress towards scientific breakeven equivalent by 2026, LM26 fast-tracks General Fusion’s technical progress to provide commercial fusion energy to the grid by the early to mid-2030s.
Exciting times for us all and I wish good luck to all of the clean energy efforts wherever they are being pursued.
My personal theme for this last year (2023) and for the coming year was and is: catching up. On the plus side, my 2023 backlog (roughly six months) to be published was whittled down considerably. On the minus side, I start 2024 with a backlog of two to three months.
2023 on this blog had a lot in common with 2022 (see my December 31, 2022 posting), which may be due to what’s going on in the world of emerging science and technology or to my personal interests or possibly a bit of both. On to 2023 and a further blurring of boundaries:
Energy, computing and the environment
The argument against paper is that it uses up resources, it’s polluting, it’s affecting the environment, etc. Somehow the part where electricity which underpins so much of our ‘smart’ society does the same thing is left out of the discussion.
Neuromorphic (brainlike) computing and lower energy
Before launching into the stories about lowering energy usage, here’s an October 16, 2023 posting “The cost of building ChatGPT” that gives you some idea of the consequences of our insatiable desire for more computing and more ‘smart’ devices,
…
In its latest environmental report, Microsoft disclosed that its global water consumption spiked 34% from 2021 to 2022 (to nearly 1.7 billion gallons , or more than 2,500 Olympic-sized swimming pools), a sharp increase compared to previous years that outside researchers tie to its AI research. [emphases mine]
“It’s fair to say the majority of the growth is due to AI,” including “its heavy investment in generative AI and partnership with OpenAI,” said Shaolei Ren, [emphasis mine] a researcher at the University of California, Riverside who has been trying to calculate the environmental impact of generative AI products such as ChatGPT.
…
Why it matters: Microsoft’s five WDM [West Des Moines in Iowa] data centers — the “epicenter for advancing AI” — represent more than $5 billion in investments in the last 15 years.
Yes, but: They consumed as much as 11.5 million gallons of water a month for cooling, or about 6% of WDM’s total usage during peak summer usage during the last two years, according to information from West Des Moines Water Works.
The focus is AI but it doesn’t take long to realize that all computing has energy and environmental costs. I have more about Ren’s work and about water shortages in the “The cost of building ChatGPT” posting.
This next posting would usually be included with my other art/sci postings but it touches on the issues. My October 13, 2023 posting about Toronto’s Art/Sci Salon events, in particular, there’s the Streaming Carbon Footprint event (just scroll down to the appropriate subhead). For the interested, I also found this 2022 paper “The Carbon Footprint of Streaming Media:; Problems, Calculations, Solutions” co-authored by one of the artist/researchers (Laura U. Marks, philosopher and scholar of new media and film at Simon Fraser University) who presented at the Toronto event.
I’m late to the party; Thomas Daigle posted a January 2, 2020 article about energy use and our appetite for computing and ‘smart’ devices for the Canadian Broadcasting Corporation’s online news,
For those of us binge-watching TV shows, installing new smartphone apps or sharing family photos on social media over the holidays, it may seem like an abstract predicament.
The gigabytes of data we’re using — although invisible — come at a significant cost to the environment. Some experts say it rivals that of the airline industry.
And as more smart devices rely on data to operate (think internet-connected refrigerators or self-driving cars), their electricity demands are set to skyrocket.
“We are using an immense amount of energy to drive this data revolution,” said Jane Kearns, an environment and technology expert at MaRS Discovery District, an innovation hub in Toronto.
“It has real implications for our climate.”
…
Some good news
Researchers are working on ways to lower the energy and environmental costs, here’s a sampling of 2023 posts with an emphasis on brainlike computing that attest to it,
Most people are familiar with nuclear fission and some its attendant issues. There is an alternative nuclear energy, fusion, which is considered ‘green’ or greener anyway. General Fusion is a local (Vancouver area) company focused on developing fusion energy, alongside competitors from all over the planet.
Part of what makes fusion energy attractive is that salt water or sea water can be used in its production and, according to that December posting, there are other applications for salt water power,
More encouraging developments in environmental science
Again, this is a selection. You’ll find a number of nano cellulose research projects and a couple of seaweed projects (seaweed research seems to be of increasing interest).
Neuromorphic computing is a subset of neuromorphic engineering and I stumbled across an article that outlines the similarities and differences. My ‘summary’ of the main points and a link to the original article can be found here,
I included an overview of the various ‘recent’ panics (in my May 25, 2023 posting below) along with a few other posts about concerning developments but it’s not all doom and gloom..
Governments have realized that regulation might be a good idea. The European Union has a n AI act, the UK held an AI Safety Summit in November 2023, the US has been discussing AI regulation with its various hearings, and there’s impending legislation in Canada (see professor and lawyer Michael Geist’s blog for more).
A long time coming, a nanomedicine comeuppance
Paolo Macchiarini is now infamous for his untested, dangerous approach to medicine. Like a lot of people, I was fooled too as you can see in my August 2, 2011 posting, “Body parts nano style,”
In early July 2011, there were reports of a new kind of transplant involving a body part made of a biocomposite. Andemariam Teklesenbet Beyene underwent a trachea transplant that required an artificial windpipe crafted by UK experts then flown to Sweden where Beyene’s stem cells were used to coat the windpipe before being transplanted into his body.
It is an extraordinary story not least because Beyene, a patient in a Swedish hospital planning to return to Eritrea after his PhD studies in Iceland, illustrates the international cooperation that made the transplant possible.
The scaffolding material for the artificial windpipe was developed by Professor Alex Seifalian at the University College London in a landmark piece of nanotechnology-enabled tissue engineering. …
This year, Gretchen Vogel (whose work was featured in my 2016 posts) has written a June 21, 2023 update about the Macchiarini affair for Science magazine, Note: Links have been removed,
Surgeon Paolo Macchiarini, who was once hailed as a pioneer of stem cell medicine, was found guilty of gross assault against three of his patients today and sentenced to 2 years and 6 months in prison by an appeals court in Stockholm. The ruling comes a year after a Swedish district court found Macchiarini guilty of bodily harm in two of the cases and gave him a suspended sentence. After both the prosecution and Macchiarini appealed that ruling, the Svea Court of Appeal heard the case in April and May. Today’s ruling from the five-judge panel is largely a win for the prosecution—it had asked for a 5-year sentence whereas Macchiarini’s lawyer urged the appeals court to acquit him of all charges.
Macchiarini performed experimental surgeries on the three patients in 2011 and 2012 while working at the renowned Karolinska Institute. He implanted synthetic windpipes seeded with stem cells from the patients’ own bone marrow, with the hope the cells would multiply over time and provide an enduring replacement. All three patients died when the implants failed. One patient died suddenly when the implant caused massive bleeding just 4 months after it was implanted; the two others survived for 2.5 and nearly 5 years, respectively, but suffered painful and debilitating complications before their deaths.
In the ruling released today, the appeals judges disagreed with the district court’s decision that the first two patients were treated under “emergency” conditions. Both patients could have survived for a significant length of time without the surgeries, they said. The third case was an “emergency,” the court ruled, but the treatment was still indefensible because by then Macchiarini was well aware of the problems with the technique. (One patient had already died and the other had suffered severe complications.)
…
A fictionalized tv series ( part of the Dr. Death anthology series) based on Macchiarini’s deceptions and a Dr. Death documentary are being broadcast/streamed in the US during January 2024. These come on the heels of a November 2023 Macchiarini documentary also broadcast/streamed on US television.
Dr. Death (anthology), based on the previews I’ve seen, is heavily US-centric, which is to be expected since Adam Ciralsky is involved in the production. Ciralsky wrote an exposé about Macchiarini for Vanity Fair published in 2016 (also featured in my 2016 postings). From a December 20, 2023 article by Julie Miller for Vanity Fair, Note: A link has been removed,
Seven years ago [2016], world-renowned surgeon Paolo Macchiarini was the subject of an ongoing Vanity Fair investigation. He had seduced award-winning NBC producer Benita Alexander while she was making a special about him, proposed, and promised her a wedding officiated by Pope Francis and attended by political A-listers. It was only after her designer wedding gown was made that Alexander learned Macchiarini was still married to his wife, and seemingly had no association with the famous names on their guest list.
Vanity Fair contributor Adam Ciralsky was in the midst of reporting the story for this magazine in the fall of 2015 when he turned to Dr. Ronald Schouten, a Harvard psychiatry professor. Ciralsky sought expert insight into the kind of fabulist who would invent and engage in such an audacious lie.
“I laid out the story to him, and he said, ‘Anybody who does this in their private life engages in the same conduct in their professional life,” recalls Ciralsky, in a phone call with Vanity Fair. “I think you ought to take a hard look at his CVs.”
That was the turning point in the story for Ciralsky, a former CIA lawyer who soon learned that Macchiarini was more dangerous as a surgeon than a suitor. …
Here’s a link to Ciralsky’s original article, which I described this way, from my April 19, 2016 posting (part 2 of the Macchiarini controversy),
For some bizarre frosting on this disturbing cake (see part 1 of the Macchiarini controversy and synthetic trachea transplants for the medical science aspects), a January 5, 2016 Vanity Fair article by Adam Ciralsky documents Macchiarini’s courtship of an NBC ([US] National Broadcasting Corporation) news producer who was preparing a documentary about him and his work.
[from Ciralsky’s article]
“Macchiarini, 57, is a magnet for superlatives. He is commonly referred to as “world-renowned” and a “super-surgeon.” He is credited with medical miracles, including the world’s first synthetic organ transplant, which involved fashioning a trachea, or windpipe, out of plastic and then coating it with a patient’s own stem cells. That feat, in 2011, appeared to solve two of medicine’s more intractable problems—organ rejection and the lack of donor organs—and brought with it major media exposure for Macchiarini and his employer, Stockholm’s Karolinska Institute, home of the Nobel Prize in Physiology or Medicine. Macchiarini was now planning another first: a synthetic-trachea transplant on a child, a two-year-old Korean-Canadian girl named Hannah Warren, who had spent her entire life in a Seoul hospital. … “
Other players in the Macchiarini story
Pierre Delaere, a trachea expert and professor of head and neck surgery at KU Leuven (a university in Belgium) was one of the first to draw attention to Macchiarini’s dangerous and unethical practices. To give you an idea of how difficult it was to get attention for this issue, there’s a September 1, 2017 article by John Rasko and Carl Power for the Guardian illustrating the issue. Here’s what they had to say about Delaere and other early critics of the work, Note: Links have been removed,
…
Delaere was one of the earliest and harshest critics of Macchiarini’s engineered airways. Reports of their success always seemed like “hot air” to him. He could see no real evidence that the windpipe scaffolds were becoming living, functioning airways – in which case, they were destined to fail. The only question was how long it would take – weeks, months or a few years.
Delaere’s damning criticisms appeared in major medical journals, including the Lancet, but weren’t taken seriously by Karolinska’s leadership. Nor did they impress the institute’s ethics council when Delaere lodged a formal complaint. [emphases mine]
Support for Macchiarini remained strong, even as his patients began to die. In part, this is because the field of windpipe repair is a niche area. Few people at Karolinska, especially among those in power, knew enough about it to appreciate Delaere’s claims. Also, in such a highly competitive environment, people are keen to show allegiance to their superiors and wary of criticising them. The official report into the matter dubbed this the “bandwagon effect”.
With Macchiarini’s exploits endorsed by management and breathlessly reported in the media, it was all too easy to jump on that bandwagon.
And difficult to jump off. In early 2014, four Karolinska doctors defied the reigning culture of silence [emphasis mine] by complaining about Macchiarini. In their view, he was grossly misrepresenting his results and the health of his patients. An independent investigator agreed. But the vice-chancellor of Karolinska Institute, Anders Hamsten, wasn’t bound by this judgement. He officially cleared Macchiarini of scientific misconduct, allowing merely that he’d sometimes acted “without due care”.
For their efforts, the whistleblowers were punished. [emphasis mine] When Macchiarini accused one of them, Karl-Henrik Grinnemo, of stealing his work in a grant application, Hamsten found him guilty. As Grinnemo recalls, it nearly destroyed his career: “I didn’t receive any new grants. No one wanted to collaborate with me. We were doing good research, but it didn’t matter … I thought I was going to lose my lab, my staff – everything.”
This went on for three years until, just recently [2017], Grinnemo was cleared of all wrongdoing.
…
It is fitting that Macchiarini’s career unravelled at the Karolinska Institute. As the home of the Nobel prize in physiology or medicine, one of its ambitions is to create scientific celebrities. Every year, it gives science a show-business makeover, picking out from the mass of medical researchers those individuals deserving of superstardom. The idea is that scientific progress is driven by the genius of a few.
It’s a problematic idea with unfortunate side effects. A genius is a revolutionary by definition, a risk-taker and a law-breaker. Wasn’t something of this idea behind the special treatment Karolinska gave Macchiarini? Surely, he got away with so much because he was considered an exception to the rules with more than a whiff of the Nobel about him. At any rate, some of his most powerful friends were themselves Nobel judges until, with his fall from grace, they fell too.
…
The September 1, 2017 article by Rasko and Power is worth the read if you have the interest and the time. And, Delaere has written up a comprehensive analysis, which includes basic information about tracheas and more, “The Biggest Lie in Medical History” 2020, PDF, 164 pp., Creative Commons Licence).
I also want to mention Leonid Schneider, science journalist and molecular cell biologist, whose work the Macchiarini scandal on his ‘For Better Science’ website was also featured in my 2016 pieces. Schneider’s site has a page titled, ‘Macchiarini’s trachea transplant patients: the full list‘ started in 2017 and which he continues to update with new information about the patients. The latest update was made on December 20, 2023.
Promising nanomedicine research but no promises and a caveat
Most of the research mentioned here is still in the laboratory. i don’t often come across work that has made its way to clinical trials since the focus of this blog is emerging science and technology,
*If you’re interested in the business of neurotechnology, the July 17, 2023 posting highlights a very good UNESCO report on the topic.
Funky music (sound and noise)
I have couple of stories about using sound for wound healing, bioinspiration for soundproofing applications, detecting seismic activity, more data sonification, etc.
I didn’t realize how active the year was art/sciwise including events and other projects until I reviewed this year’s postings. This is a selection from 2023 but there’s a lot more on the blog, just use the search term, “art/sci,” or “art/science,” or “sciart.”
2023 featured an unusual budget where military expenditures were going to be increased, something which could have implications for our science and technology research.
Then things changed as Murray Brewster’s November 21, 2023 article for the Canadian Broadcasting Corporation’s (CBC) news online website comments, Note: A link has been removed,
There was a revelatory moment on the weekend as Defence Minister Bill Blair attempted to bridge the gap between rhetoric and reality in the Liberal government’s spending plans for his department and the Canadian military.
Asked about an anticipated (and long overdue) update to the country’s defence policy (supposedly made urgent two years ago by Russia’s full-on invasion of Ukraine), Blair acknowledged that the reset is now being viewed through a fiscal lens.
“We said we’re going to bring forward a new defence policy update. We’ve been working through that,” Blair told CBC’s Rosemary Barton Live on Sunday.
“The current fiscal environment that the country faces itself does require (that) that defence policy update … recognize (the) fiscal challenges. And so it’ll be part of … our future budget processes.”
…
One policy goal of the existing defence plan, Strong, Secure and Engaged, was to require that the military be able to concurrently deliver “two sustained deployments of 500 [to] 1,500 personnel in two different theaters of operation, including one as a lead nation.”
In a footnote, the recent estimates said the Canadian military is “currently unable to conduct multiple operations concurrently per the requirements laid out in the 2017 Defence Policy. Readiness of CAF force elements has continued to decrease over the course of the last year, aggravated by decreasing number of personnel and issues with equipment and vehicles.”
Some analysts say they believe that even if the federal government hits its overall budget reduction targets, what has been taken away from defence — and what’s about to be taken away — won’t be coming back, the minister’s public assurances notwithstanding.

10 years: Graphene Flagship Project and Human Brain Project
“Graphene and Human Brain Project win biggest research award in history (& this is the 2000th post)” on January 28, 2013 was how I announced the results of what had been a a European Union (EU) competition that stretched out over several years and many stages as projects were evaluated and fell to the wayside or were allowed onto the next stage. The two finalists received €1B each to be paid out over ten years.
As you can see, there was plenty of interesting stuff going on in 2023 but no watershed moments in the areas I follow. (Please do let me know in the Comments should you disagree with this or any other part of this posting.) Nanotechnology seems less and less an emerging science/technology in itself and more like a foundational element of our science and technology sectors. On that note, you may find my upcoming (in 2024) post about a report concerning the economic impact of its National Nanotechnology Initiative (NNI) from 2002 to 2022 of interest.
Following on the commercialization theme, I have noticed an increase of interest in commercializing brain and brainlike engineering technologies, as well as, more discussion about ethics.
Meanwhile, Australia has been producing some very interesting mind/robot research, my June 13, 2023 posting, “Mind-controlled robots based on graphene: an Australian research story.” I have more of this kind of research (mind control or mind reading) from Australia to be published in early 2024. The Australians are not alone, there’s also this April 12, 2023 posting, “Mind-reading prosthetic limbs” from Germany.
I haven’t singled it out in this end-of-year posting but there is a great deal of interest in quantum computer both here in Canada and elsewhere. There is a 2023 report from the Council of Canadian Academies on the topic of quantum computing in Canada, which I hope to comment on soon.
Final words
I have a shout out for the Canadian Science Policy Centre, which celebrated its 15th anniversary in 2023. Congratulations!
For everyone, I wish peace on earth and all the best for you and yours in 2024!
It seems that Canadian nuclear energy company General Fusion has finally moved from Burnaby to Richmond (both are part of the Metro Vancouver Region). The move first announced in 2021 (see my November 3, 2021 posting for the news and a description of fusion energy; Note: fission is a different form of nuclear energy, fusion is considered clean/green).
I found confirmation of the move in an August 9, 2023 article by Kenneth Chan for the dailyhive.com
If all goes as planned, a major hurdle in fusion-based, zero-emission clean energy innovation could be produced on Sea Island in Richmond in just three years from now.
BC-based General Fusion announced today it has plans to build a new magnetized target fusion (MTF) machine at the company’s global headquarters at 6020-6082 Russ Baker Way [emphasis mine] near the South Terminal of Vancouver International Airport (YVR). [Note: YVR is located in Richmond, BC]
This machine will be designed to achieve fusion conditions of over 100,000,000°C by 2025, with “scientific breakeven” conditions by 2026. This will “fast-track” the company’s technical progress.
More specifically, this further proof-of-concept will show General Fusion’s ability to “symmetrically compress magnetized plasmas in a repeatable manner and achieve fusion conditions at scale.”
General Fusion’s technology is designed to be lower cost by avoiding other approaches that require expensive superconducting magnets or high-powered lasers.
…
The YVR machine is intended to support further work and investment and reduce the risk of General Fusion’s commercial-scale demonstration test plan in Culham Campus of the United Kingdom Atomic Energy Authority (UKAEA) — located just outside of Oxford, west of London. The UK plant has effectively been delayed, [emphasis mine] with the goal now to provide electricity to the grid with commercial fusion energy by the early to mid-2030s.
“Our updated three-year Fusion Demonstration Program puts us on the best path forward to commercialize our technology by the 2030s,” said Greg Twinney, CEO of General Fusion, in a statement. “We’re harnessing our team’s existing strengths right here in Canada and delivering high-value, industry-leading technical milestones in the near term.”
…
Canada, always a colony
I wonder what happened to the UKAEA deal. In my October 28, 2022 posting (Overview of fusion energy scene) General Fusion was downright effusive in its enthusiasm about the joint path to commercialization with a demonstration machine to be built in the UK. Scroll down to my ‘Fusion energy explanation (2)’ subhead for more details.
General Fusion announced a new Magnetized Target Fusion (MTF) machine that will fast-track the company’s technical progress. To be built at the company’s new Richmond headquarters, this ground-breaking machine is designed to achieve fusion conditions of over 100 million degrees Celsius by 2025, [emphasis mine] and progress toward scientific breakeven by 2026. In addition, the company completed the first close of its Series F raise for a combined $25 million USD (approximately $33.5 million CAD) of funding. The round was anchored by existing investors, BDC Capital and GIC. It also included new grant funding from the Government of British Columbia, which builds upon the Canadian government’s ongoing support through the Strategic Innovation Fund (SIF).
This machine represents a significant new pillar to accelerate and de-risk [emphasis mine] General Fusion’s Demonstration Program, designed to leverage the company’s recent technological advancements and provide electricity to the grid with commercial fusion energy by the early to mid-2030s.
…
Over the next two to three years, General Fusion will work closely with the UK Atomic Energy Authority [UKAEA] to validate the data gathered from [Lawson Machine 26] LM26 and incorporate it into the design of the company’s planned commercial scale demonstration in the UK.
…
So, the machine is being ‘de-risked’ in Canada first, eh?
September 2023
There was an interesting UK addition to General Fusion’s board of directors according to a September 6, 2023 news release,
Today [September 6, 2023], General Fusion announced the appointment of Norman Harrison to its Board of Directors. Norman is a world-class executive in the energy sector, with 40 years of unique experience providing leadership to both the fusion energy and nuclear fission communities.
His experience includes serving as the CEO of the UK Atomic Energy Authority (UKAEA) from 2006 to 2010 [emphasis mine], when he oversaw the groundbreaking research being conducted by the Joint European Torus (JET), the world’s largest fusion experiment and the only one operating using deuterium-tritium fuel, as it pushed the frontiers of fusion science. Norman’s expertise will support General Fusion as the company completes its Magnetized Target Fusion (MTF) demonstration, LM26 [scroll up to August 9, 2023 news release in the above for details] , at its Canadian headquarters. LM26 is targeting fusion conditions of 100 million degrees Celsius by 2025 and is charting a path to scientific breakeven equivalent by 2026. The results achieved by LM26 will be validated by the UKAEA and incorporated into the design of the company’s near-commercial machine, which is planned to be built at the UKAEA’s Culham Campus.
Norman’s background also includes leading the construction and operations of large-scale power plants. As a result, his guidance will benefit General Fusion as it progresses to commercializing its MTF technology by the early to mid-2030s.
“I’ve been a part of the fusion energy industry for many years now. General Fusion’s unique technology stands out and has exciting promise to put fusion energy onto the electricity grid,” said Norman Harrison. “I am thrilled to join the General Fusion team and be a part of the company’s progress.”
“Norman’s wealth of expertise in advancing fusion technology and operating large electricity infrastructure provides us with meaningful insight into what is required to effectively bring Magnetized Target Fusion to the energy grid in a cost-effective, practical way,” said Greg Twinney, CEO, General Fusion. “We look forward to working with him as General Fusion transforms the commercial power industry with reliable fusion power.”
About General Fusion
General Fusion is pursuing a fast and practical approach to commercial fusion energy and is headquartered in Richmond, B.C. The company was established in 2002 and is funded by a global syndicate of leading energy venture capital firms, industry leaders and technology pioneers. …
So, after postponing plans to build a build a demonstration plant with UKAEA and deciding to build it in Canada where it can be ‘de-risked’ here first, General Fusion adds a former UKAEA CEO to their company board. This seems a little strategic to me.
Today [October 11, 2023], General Fusion and Kyoto Fusioneering announced a Memorandum of Understanding (MOU) to accelerate the commercialization of General Fusion’s proprietary Magnetized Target Fusion (MTF) technology, aiming for grid integration in the early to mid-2030s. The companies will collaborate to advance critical systems for MTF commercialization, including the tritium fuel cycle, liquid metal balance of plant, and power conversion cycle.
Tritium, a hydrogen isotope and key fusion fuel, does not occur naturally and must be produced or “bred” in the fusion process. General Fusion’s game-changing commercial power plant design features a proprietary liquid metal wall that compresses plasma to fusion conditions, protects the fusion machine’s vessel components, and breeds tritium upon interacting with the fusion products. This design allows the machine to be self-sustaining, generating fuel for the life of the power plant while facilitating efficient energy extraction from the fusion reaction through a liquid metal loop to a heat exchanger.
Kyoto Fusioneering specializes in fusion power plant systems that complement the plasma confinement core, are applicable to various fusion confinement concepts, such as MTF, and are on the critical path for fusion commercialization. The complementary capabilities of both organizations will enable parallel development of key systems supporting MTF commercialization. Initial collaboration under this MOU will focus on liquid metal experimentation and fuel cycle system development at both the General Fusion and Kyoto Fusioneering facilities, such as establishment of balance of plant and power conversion test facilities, liquid metal loops, and vacuum systems.
Quotes:
“Currently, our new machine, LM26, is on-track to achieve fusion conditions by 2025, and progress towards scientific breakeven by 2026,” said Greg Twinney, CEO, General Fusion. “Harnessing the unique technological and engineering expertise of Kyoto Fusioneering will be instrumental as we translate LM26’s groundbreaking results into the world’s first Magnetized Target Fusion power plant.”
“We’re thrilled to join forces with General Fusion. Our combined expertise will accelerate the path to commercial fusion energy, a critical step toward a sustainable, decarbonized future,” said Satoshi Konishi, Co-founder and Chief Fusioneer, Kyoto Fusioneering.
Quick Facts:
Magnetized Target Fusion [prepare yourself for 1 min. 21 secs. of an enthusiastic Michel Laberge, company founder and chief science officer] uniquely sidesteps challenges to commercialization that other technologies face. The proprietary liquid metal liner in the commercial fusion machine is mechanically compressed by high-powered pistons. This enables fusion conditions to be created in short pulses rather than creating a sustained reaction. General Fusion’s design does not require large superconducting magnets or an expensive array of lasers.
General Fusion’s design will use deuterium-tritium fuel for its commercial power plant. Both are isotopes of hydrogen. Deuterium occurs naturally and can be derived from seawater. Tritium needs to be produced, which is why General Fusion’s unique and proprietary technology that breeds tritium as a byproduct of the fusion reaction is a game-changer.
Kyoto Fusioneering was spun out of Kyoto University. It is home to world-class R&D facilities, and its team has a combined total of approximately 800 years of experience [emphasis mine].

About Kyoto Fusioneering
Kyoto Fusioneering, established in 2019 [emphasis mine], is a privately funded technology startup with facilities in Tokyo and Kyoto (Japan), Reading (UK), and Seattle (USA). The company specialises in developing advanced technologies for commercial fusion power plants, such as gyrotron systems, tritium fuel cycle technologies, and breeding blankets for tritium production and power generation. Working collaboratively with public and private fusion developers around the world, Kyoto Fusioneering’s mission is to make fusion energy the ultimate sustainable solution for humanity’s energy needs.
800 years of experience seems to be a bit of a stretch for a company established four years ago with 96 employees as of July 1, 2023 (see Kyoto Fusioneering’s Company Profile webpage) but hat’s off for the sheer gutsiness of it.
Nice to learn of this news, which is on the CBC (Canadian Broadcasting Corporation) news online website. From a December 13, 2022 news item provided by Associated Press (Note: the news item was updated to include general description and some Canadian content at about 12 pm PT) ,
…
Researchers at the Lawrence Livermore National Laboratory in California for the first time produced more energy in a fusion reaction than was used to ignite it, [emphasis mine] something called net energy gain, the Energy Department said.
…
Peter Behr’s December 13, 2022 article on Politico.com about the US Department of Energy’s big announcement also breaks the news,
The Department of Energy announced Tuesday [December 12, 2022] that its scientists have produced the first ever fusion reaction that yielded more energy than the reaction required, an essential step in the long path toward commercial fusion power, officials said.
The experiment Dec. 5 [2022], at the Lawrence Livermore National Laboratory in California, took a few billionths of second. But laboratory leaders said today that it demonstrated for the first time that sustained fusion power is possible.
…
Behr explains what nuclear fusion is but first he touches on why scientists are so interested in the process, from his December 13, 2022 article,
…
In theory, nuclear fusion could produce massive amounts of energy without producing lost-lasting radioactive waste, or posing the risk of meltdowns. That’s unlike nuclear fission, which powers today’s reactors.
Fission results when radioactive atoms — most commonly uranium — are split by neutrons in controlled chain reactions, creating lighter atoms and large amounts of radiation and energy to produce electric power.
Fusion is the opposite process. In the most common approach, swirling hydrogen isotopes are forced together under tremendous heat to create helium and energy for power generation. This is the same process that powers the sun and other stars. But scientists have been trying since the mid-20th century to find a way to use it to generate power on Earth.
…
There are two main approaches to making fusion happen and I found a description for them in an October 2022 article about local company, General Fusion, by Nelson Bennett for Business in Vancouver magazine (paper version),
Most fusion companies are pursuing one of two approaches: Magnet [sic] or inertial confinement. General fusion is one of the few that is taking a more hybrid approach ¬ magnetic confinement with pulse compression.
Fusion occurs when smaller nuclei are fused together under tremendous force into larger nuclei, with a release of energy occurring in the form of neutrons. It’s what happens to stars when gravitational force creates extreme heat that turns on the fusion engine.
Replicating that in a machine requires some form of confinement to squeeze plasma ¬ a kind of super-hot fog of unbound positive and negative particles ¬ to the point where nuclei fuse.
One approach is inertial confinement, in which lasers are focused on a small capsule of heavy hydrogen fuel (deuterium and tritium) to create ignition. This takes a tremendous amount of energy, and the challenge for all fusion efforts is to get a sustained ignition that produces more energy than it takes to get ignition ¬ called net energy gain.
The other main approach is magnetic confinement, using powerful magnets in a machine called a tokomak to contain and squeeze plasma into a donut-shaped form called a torus.
General Fusion uses magnets to confine the plasma, but to get ignition it uses pistons arrayed around a spherical chamber to fire synchronously to essentially collapse the plasma on itself and spark ignition.
General Fusion’s machine uses liquid metal spinning inside a chamber that acts as a protective barrier between the hot plasma and the machine ¬ basically a sphere of plasma contained within a sphere of liquid metal. This protects the machine from damage.
The temperatures generated in fusion ¬ up to to 150 million degrees Celsius ¬ are five to six times hotter than the core of the sun, and can destroy machines that produce them. This makes durability a big challenge in any machine.
…
The Lawrence Livermore National Laboratory (LLNL) issued a December 13, 2022 news release, which provides more detail about their pioneering work, Note: I have changed the order of the paragraphs but all of this is from the news release,
…
Fusion is the process by which two light nuclei combine to form a single heavier nucleus, releasing a large amount of energy. In the 1960s, a group of pioneering scientists at LLNL hypothesized that lasers could be used to induce fusion in a laboratory setting. Led by physicist John Nuckolls, who later served as LLNL director from 1988 to 1994, this revolutionary idea became inertial confinement fusion, kicking off more than 60 years of research and development in lasers, optics, diagnostics, target fabrication, computer modeling and simulation and experimental design.
To pursue this concept, LLNL built a series of increasingly powerful laser systems, leading to the creation of NIF [National Ignition Facility], the world’s largest and most energetic laser system. NIF — located at LLNL in Livermore, California — is the size of a sports stadium and uses powerful laser beams to create temperatures and pressures like those in the cores of stars and giant planets, and inside exploding nuclear weapons.
…
LLNL’s experiment surpassed the fusion threshold by delivering 2.05 megajoules (MJ) of energy to the target, resulting in 3.15 MJ of fusion energy output, demonstrating for the first time a most fundamental science basis for inertial fusion energy (IFE). Many advanced science and technology developments are still needed to achieve simple, affordable IFE to power homes and businesses, and DOE is currently restarting a broad-based, coordinated IFE program in the United States. Combined with private-sector investment, there is a lot of momentum to drive rapid progress toward fusion commercialization.
If you want to see some really excited comments from scientists just read the LLNL’s December 13, 2022 news release. Even the news release’s banner is exuberant,
Fearful that China might wind up dominating fusion energy in the second half of this century, Congress in 2020 told DOE [Department of Energy] to begin funding development of a utility-scale fusion pilot plant that could deliver at least 50 megawatts of power to the U.S. grid.
…
In September [2022], DOE invited private companies to apply for an initial $50 million in research grants to help fund development of detailed pilot plant plans.
“We’re seeking strong partnerships between DOE and the private sector,” a senior DOE official told POLITICO’s E&E News recently. The official was not willing to speak on the record, saying the grant process is ongoing and confidential.
As the competition proceeds, DOE will set technical milestones or requirements, challenging the teams to show how critical engineering challenges will be overcome. DOE’s goal is “hopefully to enable a fusion pilot to operate in the early 2030s,” the official added.
At least 15 U.S. and foreign fusion companies have submitted requests for an initial total of $50 million in pilot plant grants, and some of them are pursuing the laser-ignition fusion process that Lawrence Livermore has pioneered, said Holland. He did not name the companies because the competition is confidential.
…
I wonder if General Fusion whose CEO (Chief Executive Officer) Greg Twinney declared, “Commercializing fusion energy is within reach, and General Fusion is ready to deliver it to the grid by the 2030s …” (in a December 12, 2022 company press release) is part of the US competition.
I noticed that General Fusion lists this at the end of the press release,
… Founded in 2002, we are headquartered in Vancouver, Canada, with additional centers co-located with internationally recognized fusion research laboratories near London, U.K., and Oak Ridge, Tennessee, U.S.A.
The Oak Ridge National Laboratory (ORNL), like the LLNL, is a US Department of Energy research facility.
As for General Fusion’s London connection, I have more about that in my October 28, 2022 posting “Overview of fusion energy scene,” which includes General Fusion’s then latest news about a commercialization agreement with the UKAEA (UK Atomic Energy Authority) and a ‘fusion’ video by rapper Baba Brinkman along with the overview.
It’s funny how you think you know something and then realize you don’t. I’ve been hearing about cold fusion/fusion energy for years but never really understood what the term meant. So, this post includes an explanation, as well as, an overview, and a Cold Fusion Rap to ‘wrap’ it all up. (Sometimes I cannot resist a pun.)
Fusion energy explanation (1)
The Massachusetts Institute of Technology (MIT) has a Climate Portal where fusion energy is explained,
Fusion energy is the source of energy at the center of stars, including our own sun. Stars, like most of the universe, are made up of hydrogen, the simplest and most abundant element in the universe, created during the big bang. The center of a star is so hot and so dense that the immense pressure forces hydrogen atoms together. These atoms are forced together so strongly that they create new atoms entirely—helium atoms—and release a staggering amount of energy in the process. This energy is called fusion energy.
More energy than chemical energy
Fusion energy, like fossil fuels, is a form of stored energy. But fusion can create 20 to 100 million times more energy than the chemical reaction of a fossil fuel. Most of the mass of an atom, 99.9 percent, is contained at an atom’s center—inside of its nucleus. The ratio of this matter to the empty space in an atom is almost exactly the same ratio of how much energy you release when you manipulate the nucleus. In contrast, a chemical reaction, such as burning coal, rearranges the atoms through heat, but doesn’t alter the atoms themselves, so we don’t get as much energy.
Making fusion energy
For scientists, making fusion energy means recreating the conditions of stars, starting with plasma. Plasma is the fourth state of matter, after solids, liquids and gases. Ice is an example of a solid. When heated up, it becomes a liquid. Place that liquid in a pot on the stove, and it becomes a gas (steam). If you take that gas and continue to make it hotter, at around 10,000 degrees Fahrenheit (~6,000 Kelvin), it will change from a gas to the next phase of matter: plasma. Ninety-nine percent of the mass in the universe is in the plasma state, since almost the entire mass of the universe is in super hot stars that exist as plasma.
To make fusion energy, scientists must first build a steel chamber and create a vacuum, like in outer space. The next step is to add hydrogen gas. The gas particles are charged to produce an electric current and then surrounded and contained with an electromagnetic force; the hydrogen is now a plasma. This plasma is then heated to about 100 million degrees and fusion energy is released.
…
Fusion energy explanation (2)
A Vancouver-based company, General Fusion, offers an explanation of how they have approached making fusion energy a reality,
Today [October 17, 2022], General Fusion and the UKAEA kick off projects to advance the commercialization of magnetized target fusion energy as part of an important collaborative agreement. With these unique projects, General Fusion will benefit from the vast experience of the UKAEA’s team. The results will hone the design of General Fusion’s demonstration machine being built at the Culham Campus, part of the thriving UK fusion cluster. Ultimately, the company expects the projects will support its efforts to provide low-cost and low-carbon energy to the electricity grid.
General Fusion’s approach to fusion maximizes the reapplication of existing industrialized technologies, bypassing the need for expensive superconducting magnets, significant new materials, or high-power lasers. The demonstration machine will create fusion conditions in a power-plant-relevant environment, confirming the performance and economics of the company’s technology.
“The leading-edge fusion researchers at UKAEA have proven experience building, commissioning, and successfully operating large fusion machines,” said Greg Twinney, Chief Executive Officer, General Fusion. “Partnering with UKAEA’s incredible team will fast-track work to advance our technology and achieve our mission of delivering affordable commercial fusion power to the world.”
“Fusion energy is one of the greatest scientific and engineering quests of our time,” said Ian Chapman, UKAEA CEO. “This collaboration will enable General Fusion to benefit from the ground-breaking research being done in the UK and supports our shared aims of making fusion part of the world’s future energy mix for generations to come.”
…
I last wrote about General Fusion in a November 3, 2021 posting about the company’s move (?) to Sea Island, Richmond,
I first wrote about General Fusion in a December 2, 2011 posting titled: Burnaby-based company (Canada) challenges fossil fuel consumption with nuclear fusion. (For those unfamiliar with the Vancouver area, there’s the city of Vancouver and there’s Vancouver Metro, which includes the city of Vancouver and others in the region. Burnaby is part of Metro Vancouver; General Fusion is moving to Sea Island (near Vancouver Airport), in Richmond, which is also in Metro Vancouver.) Kenneth Chan’s October 20, 2021 article for the Daily Hive gives more detail about General Fusion’s new facilities (Note: A link has been removed),
…
The new facility will span two buildings at 6020 and 6082 Russ Baker Way, near YVR’s [Vancouver Airport] South Terminal. This includes a larger building previously used for aircraft engine maintenance and repair.
The relocation process could start before the end of 2021, allowing the company to more than quadruple its workforce over the coming years. Currently, it employs about 140 people.
The Sea Island [in Richmond] facility will house its corporate offices, primary fusion technology development division, and many of its engineering laboratories. This new facility provides General Fusion with the ability to build a new demonstration prototype to support the commercialization of its magnetized target fusion technology.
…
As of the date of this posting, I have not been able to confirm the move. The company’s Contact webpage lists an address in Burnaby, BC for its headquarters.
With energy prices on the rise, along with demands for energy independence and an urgent need for carbon-free power, plans to walk away from nuclear energy are now being revised in Japan, South Korea, and even Germany. Last month, Europe announced green bonds for nuclear, and the U.S., thanks to the Inflation Reduction Act, will soon devote millions to new nuclear designs, incentives for nuclear production and domestic uranium mining, and, after years of paucity in funding, cash for fusion.
The new investment comes as fusion—long considered a pipe dream—has attracted real money from big venture capital and big companies, who are increasingly betting that abundant, cheap, clean nuclear will be a multi-trillion dollar industry. Last year, investors like Bill Gates and Jeff Bezos injected a record $3.4 billion into firms working on the technology, according to Pitchbook. One fusion firm, Seattle-based Helion, raised a record $500 million from Sam Altman and Peter Thiel. That money has certainly supercharged the nuclear sector: The Fusion Industry Association says that at least 33 different companies were now pursuing nuclear fusion, and predicted that fusion would be connected to the energy grid sometime in the 2030s.
… What’s not a joke is that we have about zero years to stop powering our civilization with earth-warming energy. The challenge with fusion is to achieve net energy gain, where the energy produced by a fusion reaction exceeds the energy used to make it. One milestone came quietly this month, when a team of researchers at the National Ignition Facility at Lawrence Livermore National Lab in California announced that an experiment last year had yielded over 1.3 megajoules (MJ) of energy, setting a new world record for energy yield for a nuclear fusion experiment. The experiment also achieved scientific ignition for the first time in history: after applying enough heat using an arsenal of lasers, the plasma became self-heating. (Researchers have since been trying to replicate the result, so far without success.)
…
On a growing campus an hour outside of Boston, the MIT spinoff Commonwealth Fusion Systems is building their first machine, SPARC, with a goal of producing power by 2025. “You’ll push a button,” CEO and cofounder Bob Mumgaard told the Khosla Ventures CEO Summit this summer, “and for the first time on earth you will make more power out than in from a fusion plasma. That’s about 200 million degrees—you know, cooling towers will have a bunch of steam go out of them—and you let your finger off the button and it will stop, and you push the button again and it will go.” With an explosion in funding from investors including Khosla, Bill Gates, George Soros, Emerson Collective and Google to name a few—they raised $1.8 billion last year alone—CFS hopes to start operating a prototype in 2025.
…
Like the three-decade-old ITER project in France, set for operation in 2025, Commonwealth and many other companies will try to reach net energy gain using a machine called a tokamak, a bagel-shaped device filled with super-hot plasma, heated to about 150 million degrees, within which hydrogen atoms can fuse and release energy. To control that hot plasma, you need to build a very powerful magnetic field. Commonwealth’s breakthrough was tape—specifically, a high-temperature-superconducting steel tape coated with a compound called yttrium-barium-copper oxide. When a prototype was first made commercially available in 2009, Dennis Whyte, director of MIT’s Plasma Science and Fusion Center, ordered as much as he could. With Mumgaard and a team of students, his lab used coils of the stuff to build a new kind of superconducting magnet, and a prototype reactor named ARC, after Tony Stark’s energy source. Commonwealth was born in 2015.
…
Southern California-based TAE Technologies has raised a whopping $1.2 billion since it was founded in 1998, and $250 million in its latest round. The round, announced in July, was led by Chevron’s venture arm, Google, and Sumitomo, a Tokyo-based holding company that aims to deploy fusion power in the Asia-Pacific market. TAE’s approach, which involves creating a fusion reaction at incredibly high heat, has a key advantage. Whereas ITER uses the hydrogen isotopes deuterium and tritium, an extremely rare element that must be specially created from lithium—and that produces as a byproduct radioactive-free neutrons—TAE’s linear reactor is completely non-radioactive, because it relies on hydrogen and boron, two abundant, naturally-occurring elements that react to produce only helium.
…
General Atomics, of San Diego, California, has the largest tokamak in the U.S. Its powerful magnetic chamber, called the DIII-D National Fusion Facility, or just “D-three-D,” now features a Toroidal Field Reversing Switch, which allows for the redirection of 120,000 amps of the current that power the primary magnetic field. It’s the only tokamak in the world that allows researchers to switch directions of the magnetic fields in minutes rather than hours. Another new upgrade, a traveling-wave antenna, allows physicists to inject high-powered “helicon” radio waves into DIII-D plasmas so fusion reactions occur much more powerfully and efficiently.
“We’ve got new tools for flexibility and new tools to help us figure out how to make that fusion plasma just keep going,” Richard Buttery, director of the project, told the San Diego Union-Tribune in January. The company is also behind eight of the magnet modules at the heart of the ITER facility, including its wild Central Solenoid — the world’s most powerful magnet — in a kind of scaled up version of the California machine.
But like an awful lot in fusion, ITER has been hampered by cost overruns and delays, with “first plasma” not expected to occur in 2025 as previously expected due to global pandemic-related disruptions. Some have complained that the money going to ITER has distracted from other more practical energy projects—the latest price tag is $22 billion—and others doubt if the project can ever produce net energy gain.

Based in Canada, General Fusion is backed by Jeff Bezos and building on technology originally developed by the U.S. Navy and explored by Russian scientists for potential use in weapons. Inside the machine, molten metal is spun to create a cavity, and pumped with pistons that push the metal inward to form a sphere. Hydrogen, heated to super-hot temperatures and held in place by a magnetic field, fills the sphere to create the reaction. Heat transferred to the metal can be turned into steam to drive a turbine and generate electricity. As former CEO Christofer Mowry told Fast Company last year, “to re-create a piece of the sun on Earth, as you can imagine, is very, very challenging.” Like many fusion companies, GF depends on modern supercomputers and advanced modeling and computational techniques to understand the science of plasma physics, as well as modern manufacturing technologies and materials.
“That’s really opened the door not just to being able to make fusion work but to make it work in a practical way,” Mowry said. This has been difficult to make work, but with a demonstration center it announced last year in Culham, England, GF isn’t aiming to generate electricity but to gather the data needed to later build a commercial pilot plant that could—and to generate more interest in fusion.

Magneto-Intertial Fusion Technologies, or MIFTI, of Tustin, Calif., founded by researchers from the University of California, Irvine, is developing a reactor that uses what’s known as a Staged Z-Pinch approach. A Z-Pinch design heats, confines, and compresses plasma using an intense, pulsed electrical current to generate a magnetic field that could reduce instabilities in the plasma, allowing fusion to persist for longer periods of time. But only recently have MIFTI’s scientists been able to overcome the instability problems, the company says, thanks to software made available to them at UC-Irvine by the U.S. Air Force. …
Princeton Fusion Systems of Plainsboro, New Jersey, is a small business focused on developing small, clean fusion reactors for both terrestrial and space applications. A spinoff of Princeton Satellite Systems, which specializes in spacecraft control, the company’s Princeton FRC reactor is built upon 15 years of research at the Princeton Plasma Physics Laboratory, funded primarily by the U.S. DOE and NASA, and is designed to eventually provide between 1 and 10 megawatts of power in off-grid locations and in modular power plants, “from remote industrial applications to emergency power after natural disasters to off-world bases on the moon or Mars.” The concept uses radio-frequency electromagnetic fields to generates and sustain a plasma formation called a Field-Reversed Configuration (FRC) inside a strong magnetic bottle. …
Tokamak Energy, a U.K.-based company named after the popular fusion device, announced in July that its ST-40 tokamak reactor had reached the 100 million Celsius threshold for commercially viable nuclear fusion. The achievement was made possible by a proprietary design built on a spherical, rather than donut, shape. This means that the magnets are closer to the plasma stream, allowing for smaller and cheaper magnets to create even stronger magnetic fields. …
Based in Pasadena, California, Helicity Space is developing a propulsion and power technology based on a specialized magneto inertial fusion concept. The system, a spin on what fellow fusion engineer, Seattle-based Helion is doing, appears to use twisted compression coils, like a braided rope, to achieve a known phenomenon called the Magnetic Helicity. … According to ZoomInfo and Linkedin, Helicity has over $4 million in funding and up to 10 employees, all aimed, the company says, at “enabling humanity’s access to the solar system, with a Helicity Drive-powered flight to Mars expected to take two months, without planetary alignment.”
ITER (International Thermonuclear Experimental Reactor), meaning “the way” or “the path” in Latin and mentioned in Pasternak’s article, dates its history with *fusion back to about 1978 when cold fusion was the ‘hot’ topic*. (You can read more here in the ITER Wikipedia entry.)
For more about the various approaches to fusion energy, read Pasternack’s August 17, 2022 article (The frontrunners in the trillion-dollar race for limitless fusion power) provides details. I wish there had been a little more about efforts in Japan and South Korea and other parts of the world. Pasternak’s singular focus on the US with a little of Canada and the UK seemingly thrown into the mix to provide an international flavour seems a little myopic.
Fusion rap
In an August 30, 2022 Baba Brinkman announcement (received via email) which gave an extensive update of Brinkman’s activities, there was this,
…
And the other new topic, which was surprisingly fun to explore, is cold fusion also known as “Low Energy Nuclear Reactions” which you may or may not have a strong opinion about, but if you do I imagine you probably think the technology is either bunk or destined to save the world.
That makes for an interesting topic to explore in rap songs! And fortunately last month I had the pleasure of performing for the cream of the LENR crop at the 24th International Conference on Cold Fusion, including rap ups and two new songs about the field, one very celebratory (for the insiders), and one cautiously optimistic (as an outreach tool).
You can watch “Cold Fusion Renaissance” and “You Must LENR” [L ow E nergy N uclear R eactions or sometimes L attice E nabled N anoscale R eactions or Cold Fusion or CANR (C hemically A ssisted N uclear R eactions)] for yourself to determine which video is which, and also enjoy this article in Infinite Energy Magazine which chronicles my whole cold fusion rap saga.
Here’s one of the rap videos mentioned in Brinkman’s email,
Enjoy!

Nuclear energy is not usually of much interest to me but there is a Canadian company doing some interesting work in that area. So, before getting to the news about the company’s move, here’s a general description of fusion energy and how General Fusion (the company) is approaching the clean energy problem, from a June 18, 2021 posting by Bob McDonald on the Canadian Broadcasting Corporation’s (CBC) Quirks and Quarks blog (Note: Links have been removed),
Vancouver-based fusion energy company General Fusion has entered an agreement with the United Kingdom Atomic Energy Authority to build a nuclear fusion demonstration plant to be operational in 2025. It will take a unique approach to generating clean energy.
There is an industry joke that fusion energy has been 20 years away for 50 years. The quest to produce clean energy by duplicating the processes happening at the centre of the sun has been a difficult and expensive challenge.
It has yet to be accomplished on anything like a commercial scale. That is partly because on Earth the fusion process involves handling materials at extreme pressures and temperatures many times hotter than the surface of the sun.
The nuclear technology that has provided electricity for decades around the world relies on fission, which splits heavy atoms such as uranium into lighter elements, releasing energy. However, this produces hazardous and durable radioactive waste that must be stored, and more catastrophically has led to major accidents at Chernobyl and Fukushima.
Fusion is the opposite of fission. Lighter elements such as hydrogen are heated and compressed to fuse into heavier ones. This releases energy, but with a much smaller legacy of radioactive waste, and no risk of meltdown.
The world’s largest fusion reactor experiment, ITER (Latin for “the way”) [International Thermonuclear Experimental Reactor] is currently under construction in southern France. It’s a massive international collaboration developing on fusion technology that’s been been explored since it was invented in the Soviet Union in the 1950s. It involves a doughnut-shaped metallic chamber called a tokamak that is surrounded by incredibly powerful superconducting magnets.
An electrically charged gas, or plasma, will be injected into the chamber where the magnets hold it, compressed and suspended, so it does not touch the walls and burn through them. The plasma will be heated to the unbelievable temperature of 150 million C, when fusion begins to take place.
And therein lies the problem. So far, experimental fusion reactors have required more energy to heat the plasma to start the fusion reaction than can be harvested from the reaction itself. Size is part of the problem. Demonstration reactors are small and meant to test equipment and materials, not produce power. ITER is supposed to be large enough to produce 10 times as much power as is required to heat up its plasma.
And that’s the holy grail of fusion: to produce enough power that the nuclear fusion reaction can become self-sustaining.
General Fusion takes a completely different approach by using mechanical pressure to contain and heat the plasma, rather than gigantic electromagnets. A series of powerful pistons surround a container of liquid metal with the hydrogen plasma in the centre. The pistons mechanically squeeze the liquid on all sides at once, heating the fuel by compression the way fuel in a diesel engine is compressed and heated in a cylinder until it ignites.
…
Exciting, eh? If you have time, you may want to read McDonald’s June 18, 2021 posting for a few more details about General Fusion’s technology and for some embedded images.
At one point I was under the impression that General Fusion was involved with ITER but that seems to have been a misunderstanding on my part.
I first wrote about General Fusion in a December 2, 2011 posting titled: Burnaby-based company (Canada) challenges fossil fuel consumption with nuclear fusion. (For those unfamiliar with the Vancouver area, there’s the city of Vancouver and there’s Vancouver Metro, which includes the city of Vancouver and others in the region. Burnaby is part of Metro Vancouver; General Fusion is moving to Sea Island (near Vancouver Airport), in Richmond, which is also in Metro Vancouver.) Kenneth Chan’s October 20, 2021 article for the Daily Hive gives more detail about General Fusion’s new facilities (Note: A link has been removed),
…
The new facility will span two buildings at 6020 and 6082 Russ Baker Way, near YVR’s [Vancouver Airport] South Terminal. This includes a larger building previously used for aircraft engine maintenance and repair.
The relocation process could start before the end of 2021, allowing the company to more than quadruple its workforce over the coming years. Currently, it employs about 140 people.
The Sea Island [in Richmond] facility will house its corporate offices, primary fusion technology development division, and many of its engineering laboratories. This new facility provides General Fusion with the ability to build a new demonstration prototype to support the commercialization of its magnetized target fusion technology.
…
The company’s research and development into practical fusion technology as a zero-carbon power solution to address the world’s growing energy needs, while fighting climate change, is supported by the federal governments of Canada, US, and UK.
…
General Fusion is backed by dozens of large global private investors, including Bezos Expeditions, which is the personal investment entity for Amazon founder Jeff Bezos. It has raised a total of about USD$200 million in financing to date.
“British Columbia is at the centre of a thriving, world-class technology innovation ecosystem, just the right place for us to continue investing in our growing workforce and the future of our company,” said Christofer Mowry, CEO of General Fusion, in a statement.
…
Earlier this year, YVR also indicated it is considering allowing commercial and industrial developments on several hundred acres of under-utilized parcels of land next to the north and south runways, for uses that complement airport activities. This would also provide the airport with a new source of revenue, after major financial losses from the years-long impact of COVID-19.
Over 30 years in the dreaming, the International Thermonuclear Experimental Reactor (ITER) is now said to be 1/2 way to completing construction. A December 6, 2017 ITER press release (received via email) makes the joyful announcement,
WORLD’S MOST COMPLEX MACHINE IS 50 PERCENT COMPLETED
ITER is proving that fusion is the future source of clean, abundant, safe and economic energy_
The International Thermonuclear Experimental Reactor (ITER), a project to prove that fusion power can be produced on a commercial scale and is sustainable, is now 50 percent built to initial operation. Fusion is the same energy source from the Sun that gives the Earth its light and warmth.
ITER will use hydrogen fusion, controlled by superconducting magnets, to produce massive heat energy. In the commercial machines that will follow, this heat will drive turbines to produce electricity with these positive benefits:
* Fusion energy is carbon-free and environmentally sustainable, yet much more powerful than fossil fuels. A pineapple-sized amount of hydrogen offers as much fusion energy as 10,000 tons of coal.
* ITER uses two forms of hydrogen fuel: deuterium, which is easily extracted from seawater; and tritium, which is bred from lithium inside the fusion reactor. The supply of fusion fuel for industry and megacities is abundant, enough for millions of years.
* When the fusion reaction is disrupted, the reactor simply shuts down-safely and without external assistance. Tiny amounts of fuel are used, about 2-3 grams at a time; so there is no physical possibility of a meltdown accident.
* Building and operating a fusion power plant is targeted to be comparable to the cost of a fossil fuel or nuclear fission plant. But unlike today’s nuclear plants, a fusion plant will not have the costs of high-level radioactive waste disposal. And unlike fossil fuel plants,
fusion will not have the environmental cost of releasing CO2 and other pollutants.
ITER is the most complex science project in human history. The hydrogen plasma will be heated to 150 million degrees Celsius, ten times hotter than the core of the Sun, to enable the fusion reaction. The process happens in a donut-shaped reactor, called a tokamak(*), which is surrounded by giant magnets that confine and circulate the superheated, ionized plasma, away from the metal walls. The superconducting magnets must be cooled to minus 269°C, as cold as interstellar space.
The ITER facility is being built in Southern France by a scientific partnership of 35 countries. ITER’s specialized components, roughly 10 million parts in total, are being manufactured in industrial facilities all over the world. They are subsequently shipped to the ITER worksite, where they must be assembled, piece-by-piece, into the final machine.
Each of the seven ITER members-the European Union, China, India, Japan, Korea, Russia, and the United States-is fabricating a significant portion of the machine. This adds to ITER’s complexity.
In a message dispatched on December 1 [2017] to top-level officials in ITER member governments, the ITER project reported that it had completed 50 percent of the “total construction work scope through First Plasma” (**). First Plasma, scheduled for December 2025, will be the first stage of operation for ITER as a functional machine.
“The stakes are very high for ITER,” writes Bernard Bigot, Ph.D., Director-General of ITER. “When we prove that fusion is a viable energy source, it will eventually replace burning fossil fuels, which are non-renewable and non-sustainable. Fusion will be complementary with wind, solar, and other renewable energies.
“ITER’s success has demanded extraordinary project management, systems engineering, and almost perfect integration of our work.
“Our design has taken advantage of the best expertise of every member’s scientific and industrial base. No country could do this alone. We are all learning from each other, for the world’s mutual benefit.”
The ITER 50 percent milestone is getting significant attention.
“We are fortunate that ITER and fusion has had the support of world leaders, historically and currently,” says Director-General Bigot. “The concept of the ITER project was conceived at the 1985 Geneva Summit between Ronald Reagan and Mikhail Gorbachev. When the ITER Agreement was signed in 2006, it was strongly supported by leaders such as French President Jacques Chirac, U.S. President George W. Bush, and Indian Prime Minister Manmohan Singh.
“More recently, President Macron and U.S. President Donald Trump exchanged letters about ITER after their meeting this past July. One month earlier, President Xi Jinping of China hosted Russian President Vladimir Putin and other world leaders in a showcase featuring ITER and fusion power at the World EXPO in Astana, Kazakhstan.
“We know that other leaders have been similarly involved behind the scenes. It is clear that each ITER member understands the value and importance of this project.”
Why use this complex manufacturing arrangement?
More than 80 percent of the cost of ITER, about $22 billion or EUR18 billion, is contributed in the form of components manufactured by the partners. Many of these massive components of the ITER machine must be precisely fitted-for example, 17-meter-high magnets with less than a millimeter of tolerance. Each component must be ready on time to fit into the Master Schedule for machine assembly.
Members asked for this deal for three reasons. First, it means that most of the ITER costs paid by any member are actually paid to that member’s companies; the funding stays in-country. Second, the companies working on ITER build new industrial expertise in major fields-such as electromagnetics, cryogenics, robotics, and materials science. Third, this new expertise leads to innovation and spin-offs in other fields.
For example, expertise gained working on ITER’s superconducting magnets is now being used to map the human brain more precisely than ever before.
The European Union is paying 45 percent of the cost; China, India, Japan, Korea, Russia, and the United States each contribute 9 percent equally. All members share in ITER’s technology; they receive equal access to the intellectual property and innovation that comes from building ITER.
When will commercial fusion plants be ready?
ITER scientists predict that fusion plants will start to come on line as soon as 2040. The exact timing, according to fusion experts, will depend on the level of public urgency and political will that translates to financial investment.
How much power will they provide?
The ITER tokamak will produce 500 megawatts of thermal power. This size is suitable for studying a “burning” or largely self-heating plasma, a state of matter that has never been produced in a controlled environment on Earth. In a burning plasma, most of the plasma heating comes from the fusion reaction itself. Studying the fusion science and technology at ITER’s scale will enable optimization of the plants that follow.
A commercial fusion plant will be designed with a slightly larger plasma chamber, for 10-15 times more electrical power. A 2,000-megawatt fusion electricity plant, for example, would supply 2 million homes.
How much would a fusion plant cost and how many will be needed?
The initial capital cost of a 2,000-megawatt fusion plant will be in the range of $10 billion. These capital costs will be offset by extremely low operating costs, negligible fuel costs, and infrequent component replacement costs over the 60-year-plus life of the plant. Capital costs will decrease with large-scale deployment of fusion plants.
At current electricity usage rates, one fusion plant would be more than enough to power a city the size of Washington, D.C. The entire D.C. metropolitan area could be powered with four fusion plants, with zero carbon emissions.
“If fusion power becomes universal, the use of electricity could be expanded greatly, to reduce the greenhouse gas emissions from transportation, buildings and industry,” predicts Dr. Bigot. “Providing clean, abundant, safe, economic energy will be a miracle for our planet.”

It is an extraordinary project on many levels as Henry Fountain notes in a March 27, 2017 article for the New York Times (Note: Links have been removed),
At a dusty construction site here amid the limestone ridges of Provence, workers scurry around immense slabs of concrete arranged in a ring like a modern-day Stonehenge.
It looks like the beginnings of a large commercial power plant, but it is not. The project, called ITER, is an enormous, and enormously complex and costly, physics experiment. But if it succeeds, it could determine the power plants of the future and make an invaluable contribution to reducing planet-warming emissions.
ITER, short for International Thermonuclear Experimental Reactor (and pronounced EAT-er), is being built to test a long-held dream: that nuclear fusion, the atomic reaction that takes place in the sun and in hydrogen bombs, can be controlled to generate power.
…
ITER will produce heat, not electricity. But if it works — if it produces more energy than it consumes, which smaller fusion experiments so far have not been able to do — it could lead to plants that generate electricity without the climate-affecting carbon emissions of fossil-fuel plants or most of the hazards of existing nuclear reactors that split atoms rather than join them.
Success, however, has always seemed just a few decades away for ITER. The project has progressed in fits and starts for years, plagued by design and management problems that have led to long delays and ballooning costs.
ITER is moving ahead now, with a director-general, Bernard Bigot, who took over two years ago after an independent analysis that was highly critical of the project. Dr. Bigot, who previously ran France’s atomic energy agency, has earned high marks for resolving management problems and developing a realistic schedule based more on physics and engineering and less on politics.
…
The site here is now studded with tower cranes as crews work on the concrete structures that will support and surround the heart of the experiment, a doughnut-shaped chamber called a tokamak. This is where the fusion reactions will take place, within a plasma, a roiling cloud of ionized atoms so hot that it can be contained only by extremely strong magnetic fields.
Here’s a rendering of the proposed reactor,

It seems the folks at the New York Times decided to remove the notes which help make sense of this image. However, it does get the idea across.
If I read the article rightly, the official cost in March 2017 was around 22 B Euros and more will likely be needed. You can read Fountain’s article for more information about fusion and ITER or go to the ITER website.
I could have sworn a local (Vancouver area) company called General Fusion was involved in the ITER project but I can’t track down any sources for confirmation. The sole connection I could find is in a documentary about fusion technology,
A new documentary featuring General Fusion has captured the exciting progress in fusion across the public and private sectors.
Let There Be Light made its international premiere at the South By Southwest (SXSW) music and film festival in March [2017] to critical acclaim. The film was quickly purchased by Amazon Video, where it will be available for more than 70 million users to stream.
Let There Be Light follows scientists at General Fusion, ITER and Lawrenceville Plasma Physics in their pursuit of a clean, safe and abundant source of energy to power the world.
The feature length documentary has screened internationally across Europe and North America. Most recently it was shown at the Hot Docs film festival in Toronto, where General Fusion founder and Chief Scientist Dr. Michel Laberge joined fellow fusion physicist Dr. Mark Henderson from ITER at a series of Q&A panels with the filmmakers.
Laberge and Henderson were also interviewed by the popular CBC radio science show Quirks and Quarks, discussing different approaches to fusion, its potential benefits, and the challenges it faces.
It is yet to be confirmed when the film will be release for streaming, check Amazon Video for details.
ITER is a breathtaking effort but if you’ve read about other large scale projects such as building a railway across the Canadian Rocky Mountains, establishing telecommunications in an astonishing number of countries around the world, getting someone to the moon, eliminating small pox, building the pyramids, etc., it seems standard operating procedure both for the successes I’ve described and for the failures we’ve forgotten. Where ITER will finally rest on the continuum between success and failure is yet to be determined but the problems experienced so far are not necessarily a predictor.
I wish the engineers, scientists, visionaries, and others great success with finding better ways to produce energy.
