A turbine power plant consisting of a closed loop steam turbine system and a closed loop exhaust turbine system. An external fuel source is used to drive the steam turbine system. The heat energy of the hot exhaust fluid of the steam turbine system is transferred to the exhaust turbine system, therefore driving the exhaust turbine system. The turbines used in this invention are designed to allow a heat exchange relationship between the closed loop cycle of the steam turbine system and the closed loop cycles of the exhaust turbine system. In the closed loop steam turbine system, the hot exhaust fluid of the steam turbine system flows through a conduit where it gives up heat energy to the turbines of the exhaust turbine system, prior to reaching a condenser. The working fluid, now in a liquid phase, flows through a pump and then collects heat energy from the exhaust fluid of the turbines in the exhaust turbine system, preheating the working fluid prior to reaching a heater and the steam turbine. In each of the closed loop cycles of the exhaust turbine system heat energy from the steam turbine system is used to drive the exhaust turbine. The exhaust fluid of the exhaust turbine is cooled by the steam turbine system, then the working fluid flows through the first fluid passageway of the heat exchanger and then through a condenser where the working fluid changes phase to a liquid. The working fluid now flows through a pump, through the second passageway of the heat exchanger where it is preheated; receives additional heat energy from the steam turbine system and then enters the exhaust turbine.
