1. A closed loop Rankine bottoming cycle, comprising:

  • a heat exchanger coupled to an exhaust port of a first turbogenerator, and configured to heat a pressurized refrigerant into a gaseous phase;

    a second turbogenerator coupled to the heat exchanger, and configured to expand the gaseous phase so as to create power;

    a cooling mechanism coupled to an exhaust of the second turbogenerator, and configured to cool the gaseous phase exhausted by the second turbogenerator into a liquid phase; and

    a pumping mechanism configured to pressurize the liquid phase into the pressurized refrigerant heated by the heat exchanger.
