A Sound Way to Turn Heat into Electricity
June 18th, 2007
University of Utah physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers and radars. “We are converting waste heat to electricity in an efficient, simple way by using sound,” says Orest Symko, a University of Utah physics professor who leads the effort. “It is a new source of renewable energy from waste heat.” Five of Symko’s doctoral students recently devised methods to improve the efficiency of acoustic heat-engine devices to turn heat into electricity. They will present their findings on Friday,...
