Abstract
Abstract Energy storage is accomplished for use with a thermoelectric generator in which thermopiles are provided. The source of solar energy irradiates upon the latent heat storage device to enable the heat to be stored at a relatively constant temperature to serve as the source of heat for a greater period of time than that which the solar source is providing energy. Apparatus is provided to enhance the temperature gradient in which the thermopile is located in order to increase the thermoelectric energy generated.
