We've seen some interesting nanotech power concepts in the past, but researchers at UCLA have gone back to basics and developed a printable nanotech version of a traditional battery they say could power other printed, flexible nanotech devices. The batteries, which are less than a millimeter thin, feature the same zinc-carbon makeup as traditional rechargeables, but are made by depositing thin layers of zinc and manganese oxide over a layer of nanotubes. Sadly, tech isn't producing usable amounts of power yet, but lead scientist George Gruner says the simplicity of the underlying tech should make it easy to solve that problem. Damn straight -- we're not giving up till we get a pair of electric underpants to call our own.
