Flexible speakers

speakerFollowing on from yesterday’s thin ‘n’ see-through supercapacitors now we have thin ‘n’ shiny speakers from researchers at Warwick University:

Engineers claim their new ultra-thin speakers, as well as looking good and being easy to conceal, will also deliver clearer, crisper sound.

The loudspeakers could replace public address systems in passenger terminals and shopping centres.

They could also be used as speaking posters to deliver adverts.

Cheers for clearer tannoys. Jeers for annoying talking posters.

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.

Blinded by the laser light

green_laserIn what won’t be the last instances of laser-related “friendly fire” three US soldiers in Iraq have been hospitalised, and one has been blinded in one eye, by a green dazzling laser:

Since November 2008, a single unit in Iraq “has experienced 12 green-laser incidents involving 14 soldiers and varying degrees of injury. Three soldiers required medical evacuation out of Iraq and one soldier is now blind in one eye,” writes Sgt. Crystal Reidy

Geithner kinda backs world reserve currency

euro_coinsHighlighted because I have a penchant for old school technocracy that can only be assuaged by stories of mass graves and pyramids of skulls.

Here we have news of US Treasury Secretary Tim Geithner hinting support for a global reserve currency run by the IMF:

The Chinese proposal, outlined this week by central bank governor Zhou Xiaochuan, calls for a “super-sovereign reserve currency” under IMF management, turning the Fund into a sort of world central bank.

The idea is that the IMF should activate its dormant powers to issue Special Drawing Rights. These SDRs would expand their role over time, becoming a “widely-accepted means of payments”.

Mr Geithner’s friendly comments about the SDR plan seem intended to soothe Chinese feelings after a spat in January over alleged currency manipulation by Beijing, but he will now have to explain his own categorical assurance to Congress on Tuesday that he would not countenance any moves towards a world currency.

New World Order anyone?

Robots and demographics

apriattendaNews that Japanese company Toshiba are developing a houskeeping robot – ApriAttenda – designed specifically to care for the elderly:

Japan, with a high life expectancy and low birth rate, faces a shortage of caregivers for elderly people and has loosened its tight immigration rules to invite hundreds of nurses from the Philippines and Indonesia.

As aging of the population is a common problem for developed countries, Japan wants to become an advanced country in the area of addressing the aging society with the use of robots,” the official told AFP.

It also occurs to me that I’m due to shuffle into codgerhood around circa 2060. I wonder what fifty years of R&D on ApriAttenda, or this, could lead to…
