Abstract: A cryoelectric power system for use in application(s) in which a conventional internal combustion engine is used. The power system includes a source of cryogenic fuel, a cryoelectric boiler for vaporizing the cryogenic fuel, a heat exchanger for warming the vapor, and two or more turboalternators, each turboalternator generating electricity. This power system may be utilized either as the primary power source or as secondary pending the needs of the application or location of the power requirement. The Seebeck and Ettingshausen effects may be utilized in the thermoelectric boiler, thereby producing additional electricity, and the electricity produced by the cryoelectric boiler and the turboalternators is output to appropriate controls and circuitry where it may be summed and used to power an electric power system. Superconductive material may be used in the manufacture of the turboalternators and magnetic coil for additional system enhancement.
