Using thermoelectrics to convert waste heat into clean power

My latest article for Berkeley Engineer is on UC Berkeley-born, Hayward-based Alphabet Energy and its promising new thermoelectric devices, the most advanced of their kind in the world. The company's technology offers the exciting potential of harnessing incredible amounts of power from waste heat in cars and industrial engines and generators, among other potential sources, that's otherwise lost forever, by efficiently converting it into electricity. The company's solid-state devices have no moving parts and zero emissions and can function well just about anywhere combustion-exhaust is present. For more on the company and to learn how thermoelectrics work, read the full story here.
