Acoustic devices convert heat into electricity

摘要

University of Utah physicist Professor Orest Symko and five of his doctoral students have developed small devices that can convert waste heat into electricity, harness solar energy, and cool computers and radar equipment-all by turning heat into sound and then into electricity. "We are converting waste heat to electricity in an efficient, simple way by using sound," Symko said. "It is a new source of renewable energy from waste heat."
