87:. He had previously published on thermoacoustics in space applications. TASHE uses intense sound waves to convert up to 18 percent of heat source energy into electricity for spacecraft, a significant improvement compared to prior thermoelectric generators, which converted about 7% of heat energy into electrical energy. This increased efficiency enhanced the power and capabilities of deep space probes, aligning with the goals of NASA's

Petach made significant contributions to the development and advancement of cryocoolers, particularly in space applications. Cryocoolers are devices that maintain extremely low temperatures for sensors in satellites and space telescopes, enabling them to function properly for long-term missions and
114:. This design features minimal moving parts, primarily the helium gas and an ambient temperature piston, contributing to the system's high reliability, crucial for long-duration space missions where maximizing power output from limited energy sources is essential.
34:. His notable work revolved around developing cryocoolers and the traveling-wave thermoacoustic electric generator, a technology that enhances the efficiency of power generation for spacecraft. He contributed to the development of the cryocooler system for the
