    en.wikipedia.org/wiki/Thermoacoustic_heat_engine

    A radioisotope-heated thermoacoustic system was proposed and prototyped for deep space exploration missions by Airbus. The system has slight theoretical advantages over other generator systems like existing thermocouple based systems, or a proposed Stirling engine used in ASRG prototype. [10]

    en.wikipedia.org/wiki/Thermoacoustics

    A thermoacoustic engine operates using the effects that arise from the resonance of a standing-wave in a gas. A standing-wave thermoacoustic engine typically has a thermoacoustic element called the "stack". A stack is a solid component with pores that allow the operating gas fluid to oscillate while in contact with the solid walls.

    1962 – Nikolaus Rott reopened the topic.of thermoacoustic engines described by Lord Rayleigh in 1887 and produced a full theoretical analysis which led to technological development and a working device carried on the Space Shuttle in 1992. 1992 – The first practical magnetohydrodynamic generators are built in Serbia and the USA.

    Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.

    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. [ 1 ] [ 2 ] [ 3 ] He contributed to the development of the cryocooler system for the James Webb Space Telescope 's Mid-Infrared Instrument (MIRI) and ...

    A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect).
