This invention relates to a multi-cycle power generator. More specifically, the invention relates to a power generator having a heat pump cycle and at least a hot power gener-ating cycle, the cycles being configured relative to one another to transfer heat there between two or more times in a single cycle thereby to recover energy through the reuse of unused heat energy that is typically discarded in conventional ther-modynamic cycles. The multi-cycle power gener-ator includes a heat pump cycle and a hot power cycle, wherein at least a pair of heat exchangers of the hot power cycle are common with a pair of heat exchangers of the heat pump cycle. The multi-cycle power generator may further include a cool power generating cycle In combination with the heat pump and hot power generating cycles.
