Abstract: Existing turbine energy generators currently use temperature difference to do work. To operate, they require a boiler, a condenser that usually operates at normal temperatures, a turbine, and a pump for increasing the fluid pressure, said generators mostly using water as a cooling medium. The invention is based on lowering the temperature of the condenser, such that the boiler can operate under normal operating conditions. In order to do this, 1) a cooling medium having a low boiling temperature (below 0) is used instead of water; 2) the temperature of the condenser—which is well insulated—is lowered to said temperature by using a normal secondary cooling cycle between the evaporator and the condenser, the cooling cycle transferring the excess heat from the condenser to the evaporator without the need for external cooling—this cycle uses a second cooling medium having a temperature slightly below that of the first cooling medium.
