Abstract: A closed thermodynamic system for producing electricity, including a water pump (180), a water circulation heater (110), a steam turbine (120), an electric generator (130) and a steam/water cooling sub-system (190). The water pump transfers water, having about ambient temperature, extracted from the steam/water unit to the water heating unit (165), which heats up the water that flows into the cooking sub-system (190). The water circulation heater (110) converts the water into high pressure steam which is directed to the steam turbine which converts the thermal energy to kinetic energy. The rotating turbine rotates the electric generator (130), being affixed onto the rotational axis of the turbine, and the electric generator produces electric energy. The water cooling sub-system then reduces the steam returning from the turbine into water having about ambient temperature.
