Automotive power unit combining solar cells and superconductors - uses liq. hydrogen to cool superconductor and provide power by combustion

摘要

The hybrid power-unit consists of an electromotor using high temp superconducting windings and a H2 combustion unit. The H2 is in liq form and cools the windings, in itself it is cooled by the electro-motor. The electromotor is pref driven by solar-cells, batteries or fuel-cells via an AC-convertor. Also claimed is a power-unit in which the electro-motor is driven by the combustion unit and acts as a generator. The electro-motor pref uses a magneto-calorific effect to liquefy hydrogen and return it to the cooling system. USE/ADVANTAGE - The power unit combines clean operation of the combustion unit, ie using H2 as fuel, with solar energy. The use of superconductor windings increases the efficiency of the unit, which is environmentt friendly. The use of the magnetic Carnot cycle allows heat gains in the system to be compensated for. The power unit is intended for use in automobiles, eg in lorries.
