ABSTRACT:
A system for generating electrical power supply signals includes at least one heat engine that undergoes heating/cooling cycles and corresponding temperature variations. A thermoacoustic element is thermally coupled to the chamber. The temperature variations of the heat engine induce thermoacoustic oscillations of the thermoacoustic element which form a pressure wave. At least one piezoelectric transducer is deformed by the pressure wave. A power converter can be used to transform the electric signals generated in response to deformation of the at least one piezoelectric transducer to a desired electrical power supply signal. The heat engine preferably uses a geothermal source of cold and an ambient source of hot (typically used in the summer months), or vice-versa (typically used in the winter months).
