ABSTRACT:
A variable pressure piezo electric generator comprised of a furnace chamber, a refrigerant chamber surrounding the furnace chamber in heat exchange relation thereto and a condensing chamber in communication with the refrigerant chamber. The refrigerant chamber contains a liquid refrigerant that is vaporized by the furnace heat and flows into and through the condensing chamber where it condenses. Piezo electric elements are mounted in the condensing chamber in the path of the pressurized refrigerant. An apertured plate is mounted in the condensing chamber between adjacent pairs of the piezo electric elements. The apertures in the respective plates vary in size which causes refrigerant pressure variations. As a result, the refrigerant exerts mechanical forces on the piezo electric elements causing them to produce electricity.
