Abstract : The object of the patent is to provide an energy conversion system to convert heat energy to useful electrical energy without the use of moving parts. The system includes a source of thermal energy such as the latent heat of combustion of common fossil fuels as gasoline. Spaced from the thermal energy source is a photovoltaic device such as a solar or silicon cell which is a desirable converter of radiant heat energy. A radiating solid material is positioned between and spaced from the thermal energy source and the photovoltaic device. Particularly desirable radiating solid materials are rare earth oxides such as ytterbium oxide, erbium oxide, and thulium oxide. The system also includes an interference filter positioned between the radiating solid material and the silicon cell.
