Cloud project for London 2012 Olympics includes Umberto Eco?; University of Toronto researchers work on nano nose; Nano safety research centre in Scotland

Shades of the 19th century! One of the teams competing to build a 2012 Olympics tourist attraction for London’s east end has proposed digital clouds. According to the article (Digital cloud plan for city skies) by Jonathan Fildes, online here at BBC News,

The construction would include 120m- (400ft-) tall mesh towers and a series of interconnected plastic bubbles that can be used to display images and data.

The Cloud, as it is known, would also be used [as] an observation deck and park

The idea of displaying images and data on clouds isn’t entirely new,

… the prospect of illuminated messages on the slate of the heavens … most fascinated experts and layman. “Imagine the effect,” speculated the Electrical Review [Dec. 31, 1892], “if a million people saw in gigantic characters across the clouds such words as ‘BEWARE OF PROTECTION’ and “FREE TRADE LEADS TO H–L!”

(The passage is from Carolyn Marvin’s book, When old technologies were new.) I’m not sure what protection refers to but the reference to free trade still feels fresh.

I always find technology connections to the past quite interesting as similar ideas pop up independently from time to time and I’d be willing to bet the 2012 cloud team has no idea that displaying messages on clouds had been proposed as far back as the 1890s.

The current project has some interesting twists. The team is proposing to fund it with micro-donations from millions of people. From the BBC article,

“It’s really about people coming together to raise the Cloud,” Carlo Ratti, one of the architects behind the design from the Massachusetts Institute of Technology (MIT) told BBC News.

“We can build our Cloud with £5m or £50m. The flexibility of the structural system will allow us to tune the size of the Cloud to the level of funding that is reached.”

The size of the structure will evolve depending on the number of contributions, he said.

The cloud will not consume power from the city’s grid.

“Many tall towers have preceded this, but our achievement is the high degree of transparency, the minimal use of material and the vast volume created by the spheres,” said professor Joerg Schleich, the structural engineer behind the towers.

Professor Schleich was responsible for the Olympic Stadium in Munich as well as numerous lightweight towers built to the same design as the Cloud.

The structure would also be used to harvest all the energy it produces according to Professor Ratti.

“It would be a zero power cloud,” he said.

The team in addition to designers, scientists, and engineers includes Umberto Eco, a philosopher, semiotician, novelist, medievalist, and literary critic.

Yes, they have a writer on the team for a truly interdisciplinary approach. Or not. Eco may have lent his name to the project and not been an active participant. Still, I’m much encouraged by Eco’s participation (regardless of the amount or type) in this project as I think writers have, for the most part, been fusty and slow to engage with the changes we’re all experiencing.

At the University of Toronto (U of T), researchers are working on a project that they hope will be of interest to NASA ([US] National Aeronautics and Space Administration). From the news item on Azonano,

Thankfully, there is no failure to launch at U of T’s new electron beam nanolithography facility where researchers are already developing smaller-than-tiny award-winning devices to improve disease diagnoses and enhance technology that impacts fields as varied as space exploration, the environment, health care and information and media technologies.

One of these novel nano-devices, being developed by PhD student Muhammad Alam, is an optical nose that is capable of detecting multiple gases. Alam hopes it will be used by NASA one day.

Alam is working on a hydrogen sensor which can be used to detect the gas. Hydrogen is used in many industries and its use is rising so there is great interest in finding ways to handle it more safely and effectively. As for NASA, sometimes those rockets don’t get launched because they detect a hydrogen leak that didn’t actually happen. The U of T ‘nose’ promises to be more reliable than the current sensors in use.

Scotland is hosting one of the first nanomaterials research centres in the UK. From the news item on Nanowerk,

Professor Anne Glover, Chief Scientific Adviser for Scotland officially launched the new centre today (Wednesday, November 11) at Edinburgh Napier’s Craighouse Campus.
She said: “Given the widespread use of nanomaterials in [a] variety of everyday products, it is essential for us to fully understand them and their potential impacts. This centre is one of the first in the UK to bring together nano-science research across human, environment, reproductive health and microbiology to ensure the safe and sustainable ongoing use of nanotechnology.”
Director of the Centre for Nano Safety, Professor Vicki Stone said: “Nanomaterials are used in a diverse range of products from medicines and water purifiers to make-up, food, paints, clothing and electronics. It is therefore essential that we fully understand their longterm impact. We are dedicated to understanding the ongoing health and environmental affects of their use and then helping shape future policy for their development. The launch of this new centre is a huge step forward in this important area of research.”

It’s hard to see these initiatives (I mentioned more in yesterday’s [Nov. 10, 2009] posting) in the UK and Europe and not contrast them harshly with the Canadian scene. There may be large scale public engagement, public awareness, safety initiatives, etc. for nanotechnology in Canada but nobody is giving out any information about it.
