Back in May I mentioned the idea of using the human body to power the myriad electronic devices that we carry on our persons. At that time, I’d never heard of anybody actually doing it. A friend today sent me this link to a press release from Applied Digital Solutions.  They have developed a miniaturized thermoelectric generator that converts low gradient body heat flow into electrical power. Supplying 1.5 volts at 10 micro amps, the thing won’t power a cell phone, but it’s plenty to power implanted medical devices and maybe even a wristwatch. So I’m not a total nutball.
