Los Alamos National Laboratory - Acoustic Stirling Heat Engine
The acoustic Stirling heat engine developed at Los Alamos National Laboratory efficiently converts heat to intense acoustic power in a simple device that comprises only pipes and conventional heat exchangers and has no moving parts. The acoustic power can be used directly in acoustic refrigerators or pulse-tube refrigerators to provide heat-driven refrigeration with no moving parts, or it can be used to generate electricity via a linear alternator or other electroacoustic power transducer.
