Thermoacoustic" Stirling motors
Thermoacoustic converters

As explained in the article [BE 8 060] Thermoacoustic converters. Thermoacoustic effect, the phenomenon of thermoacoustic amplification of mechanical energy in the form of an acoustic wave can be used to create motors by transforming the heat supplied by the hot source. In conjunction with an electrical generator, thermoacoustic systems are already being used for nomadic electrical generators by organizations such as NASA in the United States.
