AN IMPROVED BINARY VAPOR POWER PLANT HAVING A CLOSED PRIMARY SYSTEM AND A SECONDARY SYSTEM, SAID CLOSED PRIMARY SYSTEM COMPRISING; A PRIMARY WORKING FLUID SELECTED FROM THE GROUP CONSISTING OF FLUID SULFUR AND FLUID SULFIDES OF PHOSPHORUS, A HEAT SOURCE TO RECEIVE SAID PRIMARY WORKING FLUID IN A SUBSTANTIALLY LIQUID STATE AND TO CONVERT SAID PRIMARY WORKING FLUID TO A SUBSTANTIALLY SATURATED VAPOR STATE, A HEAT ENGINE OPERABLY ASSOCIATED WITH SAID HEAT SOURCE TO RECEIVE SAID SUBSTANTIALLY VAPORIZED PRIMARY WORKING FUID FROM SAID HEAT SOURCE AND TO PRODUCE A FIRST OUTPUT OF ENERGY BY EXPANDING SAID SUBSTANTIALLY VAPORIZED PRIMARY WORKING FLUID AGAINST A WORKING SURFACE WHEREBY SAID SUBSTANTIALLY VAPORIZED PRIMARY WORKING FLUID IS SUPERHEATED, A HEAT EXCHANGER OPERABLY ASSOCIATED WITH SAID HEAT ENGINE TO RECEIVE SAID SUPERHEATED PRIMARY WORKING FLUID FROM SAID HEAT ENGINE AND TO CONDENSE SAID PRIMARY WORKING FLUID TO A SUBSTANTIALLY LIQUID STATE, AND CONDUIT MEANS TO TRANSFER SAID SUBSTANTIALLY LIQUID PRIMARY WORKING FLUID FROM SAID HEAT EXCHANGER TO SAID HEAT SOURCE AND THEREBY COMPLETE THE CYCLE OF SAID CLOSED PRIMARY SYSTEM; AND SAID SECONDARY SYSTEM COMPRISING: A SECONDARY WORKING FLUID, SAID HEAT EXCHANGER OF SAID CLOSED PRIMARY SYSTEM BEING INCLUDED IN SAID SECONDARY SYSTEM AND BEING DISPOSED TO RECEIVE SAID SECONDARY WORKING FLUID IN A SUBSTANTIALLY LIQUID STATE AND TO CONVERT SAID SECONDARY WORKING FLUID TO A SUBSTANTIALLY VAPOR STATE BY THE TRANSFER OF HEAT THERETO FROM SAID PRIMARY WORKING FLUID, A SECOND HEAT ENGINE OPERABLY ASSOCIATED WITH SAID HEAT EXCHANGER TO RECEIVE SAID SUBSTANTIALLY VAPORIZED SECONDARY WORKING FLUID FROM SAID HEAT EXCHANGER AND TO PRODUCE A SECOND OUTPUT OF ENERGY BY REMOVING HEAT FROM SAID SECONDARY WORKING FLUID AND CONVERTING THE HEAT REMOVED INTO ENERGY, AND A HEAT SINK OPERABLY ASSOCIATED WITH SAID SECOND HEAT ENGINE TO RECEIVE THE SECONDARY WORKING FLUID FROM THE SECOND HEAT ENGINE AND TO CONDENSE SAID SECONDARY WORKING FLUID TO A SUBSTANTIALLY SATURATED LIQUID.
