Abstract
A combined cycle thermodynamic heat flow process for the high efficiency conversion of heat energy into mechanical shaft power is disclosed. This process is particularly useful as a high efficiency energy conversion system for the supply of electrical power (and in appropriate cases thermal services). The high efficiency energy conversion system is also disclosed. A preferred system comprises dual closed Brayton cycle systems, one functioning as a heat engine, the other as a heat pump, with their respective closed working fluid systems being joined at a common indirect heat exchanger. The heat engine preferably is a gas turbine, capable of operating at exceptionally high efficiencies by reason of the ability to reject heat from the expanded turbine working fluid in the common heat exchanger, which is maintained at cryogenic temperatures by the heat pump system. The heat pump system usefully employs gas turbine technology, but is driven by an electric motor deriving its energy from a portion of the output of the heat engine.
