Thermoelectric power generators harvest energy from waste or natural heat without producing any direct emissions of greenhouse gases. As one of the most promising clean energy conversion technologies, thermoelectric materials transform temperature gradients into electrical power without any moving parts. Existing thermoelectric materials are limited by toxicity at high temperatures and low conversion efficiency.

This new thermoelectric energy harvester is a novel oxide-based thermoelectric material that exhibits high electrical and thermal conductivity for increased performance. The material has a “cool” side and a “heated” side that uses the temperature differential to generate electrical power. Possible uses in automobiles, power plants, generators, or anything with heat.
