Embodiments of systems that are configured as a closed loop system with a pump, an evaporator, a power generator, and a condenser, the combination of which circulates a working fluid to generate electrical power. The embodiments are configured with a cooling system that can depress the local pressure at or near components that are the target of cooling, which in turn permits the cooling fluid to function at temperatures that can remove heat, even when the ambient temperature rises above desirable levels. In one embodiment, the system is configured with an ejector device that can use energy of the working fluid F in vapor phase to lower the pressure in a housing, or like environment, that encloses critical elements of the generator.
