Nanowires Allow For Electricity-Generating Clothing 113
lee1 writes "The latest development in the field of 'energy harvesting', which includes such
opportunistic technology such as self-winding watches, generators implanted in soldier's boots, and knee brace dynamos, is a cloth that generates electrical power. The cloth is newly developed by scientists in the US, and can produce up to 80 milliwatts per square metre. It is made from
brush-like fibres composed of a Kevlar stalk surrounded by zinc oxide nanowire crystals that generate electricity through the piezoelectric effect. They can be grown on any substrate, including hair. The power harnessed from this effect could be used for anything from cosmetic components to the powering of medical devices."

So how much power is that in practice? 5mW PSM? maybe 10 if you're an athlete?
I think I'll stick to batteries, thanks

There is a lot of passive mechanical energy in our environment that can be harvested to generate power. But it has to make economical sense. If you can coat your house in nano piezoelectric filaments that generate twice the current that they cost, then good. Otherwise, why bother?

Or you could use these technologies in camping/hiking gear. Charge up your phone/laptop/radio while simply walking through the countryside.
Or they could be used to create tech-friendly apparel. A jacket, perhaps, that keeps your iPod charged up at all times.
Or they could be used to supply power where the local infrastructure is damaged or outright missing. Throw up some tents/shelters made out of this cloth and generate electricity for lighting.
Or maybe something to throw into a survival kit. A little radio beacon sending out a constant SOS that's powered by your movement, or the clothes you wear.
I mean, there are literally tons of non-green reasons to look into technology like this. It may never be an economically viable way to generate large-scale electricity... You may never power your house with it... But there are also plenty of places/situations where economics are not the most important factor.
