It may someday be possible to keep electronic devices powered with camping stoves. The excess heat produced could be used to create a thermoacoustic engine, which converts thermal energy into acoustic energy. This energy can then be transformed into mechanical or electrical energy. Optimized, these engines can generate power ranging from tens to thousands of watts. A goal is to establish a foundation for more efficient energy conversion devices, with significant applications in aviation, marine engineering, and industrial waste heat recovery.
