The heat might be generated at the engine, or it might be generated by the engine doing work on something in the environment or in creating electric current. There would essentially be an adiabatic transfer of energy from one form to another after the engine gets going unless the energy is allowed to exit the system. The fact that the Papp engine is not reported to heat up significantly adds an interesting twist to the story. Eric
