Sound From Heat

Caption: University of Utah physicist Orest Symko demonstrates how heat can be converted into sound by using a blowtorch to heat a metallic screen inside a plastic tube, which then produces a loud tone, similar to when air is blown into a flute. Symko and his students are developing much smaller devices that not only convert heat to sound, but then use the sound to generate electricity. The devices may be used to cool electronics, harness solar energy in a new way, and conserve energy by changing waste heat into electric power.
