Reinventing the engine
There has been much progress in the development of thermoacoustic engines and refrigerators over the past 20 years. Backhaus and Swift have developed a thermoacoustic Stirling engine at the Los Alamos National Laboratory involving the use of a surge volume and a gentle flow constriction at the closed end of the resonator to produce sufficient pressure difference over the regenerator. It incorporates a novel jet pump, using acoustics to create the necessary back pressure for cancel the streaming.
