Abstract
A thermoacoustic energy converter for converting heat energy to electricity includes an annular resonator with a regenerator disposed therein. An electro-mechanical transducer is coupled to the annular resonator and in fluid communication with the working fluid. When heat is applied to one end of the annular resonator, a traveling acoustic wave is generated in the annular resonator causing vibrations in the working fluid that actuate the electro-mechanical transducer to generate electricity.
