Wonder stuff: Heat scavengers promise energy bonanza - 0 views

Reclaim even a small amount of that lost heat as electricity, and that would massively boost energy efficiency. Thermoelectric materials allow us to do just that, by coaxing a current from a temperature difference. Wrap a thermoelectric substance around your car's exhaust, and its waste heat could power the electrics. Incorporate thermoelectric elements into a refrigerator, and heat extracted from its interior could power it
