Thermoacoustic refrigeration for space applications
Space Programs and Technologies Conference, 1991 A thermoacoustic refrigerator has been designed, tested, and certified by NASA to be flown aboard the space-shuttle get-away-special (GAS) payload program on STS-42 in January 1992. This thermoacoustic heat pump uses acoustic power to pump heat from a low-temperature source to a high-temperature sink. It has only 15 g of moving mass operating at 400 Hz,

Mover guide in a linear electric generator with double‐sided stationary stators
The Journal of Engineering, Volume 2019, Issue 17, Page 3986-3990, June 2019., 2019 This study addresses double‐sided stationary stators in a linear electric generator with similar operation to a linear oscillatory motion electric machine. The plate mover in the linear electric generator's double‐sided stationary stators is powered by the acoustic power output of the thermoacoustic engine's acoustic line.
