Flexible and transparent supercapacitors

flexibletranNews of carbon nanotube and indium nanowire-based supercapacitors that can be bent and twisted like a playing card:

It continues a line of prototype devices created at the USC Viterbi School of Engineering that can perform the electronic operations now usually handled by silicon chips using carbon nanotubes and metal nanowires set in indium oxide films, and can potentially do so at prices competitive with those of existing technologies.

Its creators believe the device points the way to further applications, such as flexible power supply components in “e-paper” displays and conformable products.

This sounds like the sort of development that could lead to something like The Young Lady’s Illustrated Primer of The Diamond Age by Neal Stephenson.

Hacker havens are ad-hocracies

hacker's workbenchWhen the going gets tough, the geeks gang together; Wired reports on the spreading global phenomenon of ‘hacker spaces’ – community owned and operated workshops full of tools and parts that provide a home away from home for the technically-minded.

At the center of this community are hacker spaces like Noisebridge, where like-minded geeks gather to work on personal projects, learn from each other and hang out in a nerd-friendly atmosphere. Like artist collectives in the ’60s and ’70s, hacker spaces are springing up all over.

Interesting throw-away comparison – is the increasing ubiquity of technology making it into a branch of the plastic arts? Or did that happen a long time ago, with no one in the arts being willing to admit it?

There are now 96 known active hacker spaces worldwide, with 29 in the United States, according to Hackerspaces.org. Another 27 U.S. spaces are in the planning or building stage.

Located in rented studios, lofts or semi-commercial spaces, hacker spaces tend to be loosely organized, governed by consensus, and infused with an almost utopian spirit of cooperation and sharing.

Uh-oh, the U-word…nothing good ever comes of utopias, does it? Still, one man’s utopia is another man’s logically structured system of governance:

Many are governed by consensus. Noisebridge and Vienna’s Metalab have boards, but they are structured to keep board members accountable to the desires of the members. NYC Resistor is similarly democratic. Most of the space — and the tools — are shared by all members, with small spaces set aside for each member to store items and projects for their own use.

“The way hacker spaces are organized seems to be a reaction against American individualism — the idea that we all need to be in our separate single-family homes with a garage,” says White. “Choosing to organize collectives where you’re sharing a space and sharing tools with people who are not your family and not your co-workers — that feels different to me.”

Things may differ in continental Europe, but it sounds pretty different to this British citizen, too; it’s not just the US that developed a knee-jerk reaction to anything that smacks even slightly of communism. That said, I’d be overjoyed if someone set one of these places up in my town – if nothing else, it would be nice to geek out in company for a change. [image by Justin Marty]

We’ll leave the final few comments to Chairman Bruce Sterling:

These enterprises really have the look-and-smell of a post-Meltdown Transition Web.

Indeed; Bicycle Repair Men for the noughties, you might say.

Let’s hope the inhabitants stay clear on the concept, and don’t start whacking each other in a mafia-style street struggle for tech turf.

And you people email in saying I’m negative…

Grid2.0 – electricity as commodity

electricity pylonsMuch attention is currently (arf!) focussed on making our energy grids cheaper and more efficient, with lots of new ideas being batted around. Here’s a proposal which already appears to be working in one region: start treating electricity as a commodity as well as a utility.

Treat electricity like a commodity—something for which you can gauge demand and set a price in advance. That’s what New England’s independent system operator started doing last year. In its Forward Capacity Market, the ISO projects how much power the region will need three years ahead and then runs a descending-clock auction for the right to provide it. The ISO doesn’t care whether it gets its power from increased production of megawatts or from efficiencies added to the system, so-called negawatts. The agency simply sets the starting price.

Result: money saved in power plants and wires, more stable electricity bills, and a homegrown incubator for getting bright green ideas off the drawing board.

Anything that can prevent my quarterly electricty bill from doubling in cost as it did over the winter just past sounds like a good plan to me, though I’m never astonishingly keen on introducing middleman agencies into an already costly system.

Furthermore, I’m not sure how much protection the commodity trading of electricity would grant us from the civilisation-smashing power of solar weather[image by aloshbennett]

Travel to Mars… without ever leaving the parking lot

MarsSo, do you think you could cope with the cramped conditions and prison psychology that would be an inevitable part of a manned mission to Mars and back?

Well, here’s the test – we’ll lock you in a fake space capsule that’s sitting in a parking lot somewhere outside of Moscow for about a hundred days with five other people and watch you through cameras to see how you get on.

The idea is for the 550 cubic-metre “ground exploration complex” (GEC) to recreate as closely as possible the atmosphere of a spacecraft racing through the solar system, bombarded by cosmic radiation. Any return flight to Mars – at least 34 million miles from our planet – would take between 18 months and three years, including landing and exploration.

The volunteers – four Russians, a French airline pilot and a German army engineer – will be kept under constant camera surveillance to record the physical and psychological impact of their time in the isolation chamber.

Isn’t this lifted wholesale from a J G Ballard story? You’re surely going to get some industrial-grade cabin fever going on…

Mark Belokovksy of the IMBP admitted the psychological pressure of living in close quarters with five other human beings could crack even the toughest guinea pigs.

“Tension is inevitable,” he said candidly. The fact the 105-day “flight” will be a single-sex trip on this occasion may be a blessing. During a similar experiment in 1999 the participants were given vodka to celebrate New Year’s Eve: two members then got in a fist fight after one tried to kiss a female volunteer from Canada.

Yeesh; the green-eyed monster in outer space, no less. I wonder where I can find details about that Canadian experiment – I’m curious to know whether the women fared any better at the isolation than the men did. Would an all-female crew be more stable, or less? How about a crew of eunuchs?

But if you’ll permit me a brief flight of fancy, mashing up this story with that half-remembered Ballard piece and the Moon hoax conspiracy theories: I wonder if it would be possible for a government with sufficient space capability to run an entirely faked CGI Mars mission that fooled everyone, even the cosmonauts themselves?

Uxo, Bomb Rat

RatWe interrupt our usually po-faced seriousness for a brief dose of vaguely topical cute… assuming your definition of cute extends to rodents.

You may have read and enjoyed Eliot Fintushel’s “UXO, Bomb Dog” when we published it here last year (and if not, you should, because it’s a great story), but you may not have been aware that even smaller animals can be trained to de-mine battlefields – like rats.

Trainers begin socialising the young rats to the sights, sounds, and textures of the world by walking them on wet grass, going for a ride in a lorry and interacting with humans.

Then the sniffer rats are taught to recognise the smell of metal land mine casings in return for a food reward.

Thirty sniffer rats are already being used in Mozambique, Africa, and have proved incredibly successful for the detection and removal of land mines.

The rodents are fitted to a leash before scrambling their way over a piece of ground, sniffing out any explosives.

A trained rat can clear 100 metres square in 30 minutes, equivalent to two days work for a manual de-miner.

I used to share a house with a guy who kept rats, and I can vouch for their intelligence… and their tenacity. Their ability to come when they’re called? Not so much. [via grinding.be; image by charlycoste]
