We may be some time away from the point where a society of machines enslaves the human race to power itself with our body heat. But we’re one step closer. From NBC News:
The Lumen is a new flashlight that skips the AAs, producing light by harvesting your body heat, and it’s looking for funding on Kickstarter. There are no switches, ports, compartments or anything — just a machined metal frame, a single bright LED, and a big thumbprint where you need to touch the device. Inside, a thermoelectric generator captures energy from the way electrons move around when there’s a temperature differential — just enough to provide a little light.
The Lumen is a successful Kickstarter project. Pre-orders are available now.
