Body Heat Electricity
Those clever German researchers are at it again, this time over at the Fraunhofer Institute. They have developed "entire electronic systems" that can run off of body heat turned electricity. The picture above shows a wireless transmitter being powered by the heat given off by a person's hand via a thermoelectric generator. Of course the wireless transmitter only needs 200 millivolts to operate. So when they say "entire electronic systems" can run off body heat, I think what they meant was pretty much nothing. Wake me up when I can power a portable videogame system by holding it. Ka-ching! Don't steal that idea.

This is the conceptual AIRE mask. The idea is that you just strap it to your face and charge your iPhone simply by breathing. The Hannibal Lector look is just an added bonus! No word if breathing heavy like a f***ing creeper makes it charge any faster. The AIRE mask is a co... / Continue →
