Thermoacoustic energy harvesting [PDF]
Journal of the Acoustical Society of America, 2015 Thermoacoustics have a key role to play in energy harvesting systems, exploiting a temperature gradient to produce powerful acoustic pressure waves. As the name suggests, thermoacoustics is a blend of two distinct disciplines: thermodynamics and acoustics.
