ABSTRACT:
A method and apparatus for implementing a thermodynamic cycle, which includes heating and preferably partially evaporating a multicomponent liquid working stream with heat released from the partial condensation of a returning spent stream. The preferably partially evaporated working stream is then completely evaporated with heat transferred from an external heat source, which is preferably a geothermal heat source. The evaporated stream is expanded to produce the spent stream, which, in turn, is condensed to produce the multicomponent liquid working stream.
