Abstract
A non-pollution motor powered from a source of a low pressure liquified cryogenic is disclosed. A means for converting, upon demand, a quantity of the cryogenic into a high pressure gas is connected between a gas expander and a storage volume tank. The high pressure gas stored in the volume tank is used to power a gas turbine motor. The gas turbine in turn drives a DC-generator to produce a voltage that both charges a battery pack and drives an output DC-drive motor. When the battery pack is fully charged, the gas turbine is turned off, and the DC-drive motor is powered solely from the battery pack. When the batteries have discharged, the turbine is turned on to drive the DC-generator once again. Both the DC-generator and the DC-drive motor are contained in the cryogenic in heat exchange relationship to cool the units to essentially the temperature of the cryogenic.
