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.

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.

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.

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’).
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

“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.
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.

“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.

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.
