Abstract
Abstract Non-pollution motors wherein liquid nitrogen is evaporated to drive a gas motor, the gas motor driving an alternator (electrical generator) the output from which is used to drive an electric drive motor which may be used to propel an automotive vehicle or may be used to drive any other equipment. The electric drive motor is operated at reduced temperature so that its operating characteristics are greatly improved.
