ABSTRACT:
Apparatus and method for converting heat to electrical energy by the use of one or more capacitors having temperature dependent capacitance are disclosed. The capacitor is cycled between relatively high and relatively low temperatures. Upon heating of the capacitor, the capacitance thereof is reduced, so that a charge therein is caused to expand into associated efficient external circuitry in which it is available to do electrical work. The capacitor is then cooled and recharged and the cycle is repeated. The electrical output of the capacitor results from the regenerative delivery of heat to and removal of heat from the capacitor, and efficient conversion of heat to electric energy is thereby effected.
