With rising energy costs and our growing arsenal of iPads, smart phones, and wearable monitors, we're always on the lookout for new ways to power our devices. Perpetua Power, an Oregon-based startup, has invented a chip that can turn heat into energy – specifically the heat from your own body. When placed against your skin, the one square-inch TEGwear thermoelectric generator outputs up to three volts. One generator is enough to power headphones or a pedometer; a battery of them sewn into your favorite jumpsuit might even provide enough power for a phone. Maybe the TEGwear chip will be the intermediate step between old-and-tired fossil fuels and our fat-powered Energy Belt.
