Stirling-electric hybrid automobile
The Stirling-Electric Hybrid automobile herein disclosed utilizes an electric drive motor which is powered by electric storage device. The electric storage device is kept at suitable charge by electric generator mechanically driven by external combustion of Stirling engine type, by thermoelectric generator thermally coupled to the exhaust of the Stirling engine and to kinetic energy recovery system which during deceleration of the automobile utilizes the electric drive motor as a generator and recovering the electrical energy generated by deceleration to the electric storage device. Almost any clean combusting liquid or gaseous fuel may be utilized by the Stirling engine with greater fuel economy and less atmospheric pollution than internal combustion engines presently used. The utilization of thermoelectric generator to recover heat from exhaust of the Stirling engine and utilization of kinetic energy recovery system provides even better fuel efficiency and reduced pollution.
