This patent describes a method for implementing a thermodynamic cycle. It comprises: expanding a gaseous working stream transforming its energy into usable form and producing a spent stream; reheating and expanding the spent stream, to transform its energy into usable form; heating a multicomponent oncoming liquid working stream by partially condensing the spent stream to preheat and partially evaporate the multicomponent oncoming liquid working stream to produce a heated liquid working stream; and evaporating the heated liquid working stream using heat produced by an external heat source, to form the gaseous working stream.
