1. A cogeneration system for providing heat and electric power to a vehicle such as a truck having an engine cooled by a liquid engine coolant when said engine is not operating comprising: a working fluid  a turbine having a turbine inlet and a turbine outlet,  an electric generator coupled with said turbine for being driven thereby,  a fuel burning heater for vaporizing said working fluid for supplying vapor to said turbine inlet,  a condenser for receiving spent said working fluid vapor from said turbine outlet and condensing it to be liquid working fluid,  a first pump for pumping said liquid working fluid from said condenser to said heater be heated and vaporized,  a second pump for pumping said engine coolant through said condenser for heating said coolant with heat from said spent working fluid vapor, and  a control means for controlling said fuel burning heater, said first pump and said second pump to operate at certain times.  said heater comprises a catalytic combustor.  said means for driving said first pump is an electric motor.  said first pump is a gerotor pump.  said means for driving said second pump is an electric motor.  said second pump is a centrifugal pump.  said working fluid when vaporized and entering said turbine inlet is pressurized to a pressure below atmospheric pressure.  said working fluid is decane.  said working fluid is aniline.  said generator is a permanent magnet generator, and  said control means also controls said generator. 2.
