Binary vapor generating systems for electric power generation

Claim 1

A BINARY VAPOR GENERATING SYSTEM COMPRISING, IN COMBINATION, A FIRST STAGE HAVING A SUBSTANTIALLY CLOSED CIRCULATION PATH CONTAINING WATER, AND INCLUDING A FIRST VAPORIZING MEANS, A FIRST HEAT ENGINE, AND FIRST CONDENSING MEANS CONNECTED BETWEEN THE OUTLET OF SAID HEAT ENGINE AND THE INLET OF SAID VAPORIZING MEANS; AND A SECOND STAGE HAVING A SUBSTANTIALLY CLOSED CIRCULATION PATH CONTAINING A SECOND FLUID MEDIUM HAVING A CRITICAL TEMPERATURE LESS THAN THAT OF WATER AND A FREEZING POINT SUBSTANTIALLY LESS THAN THE PREVAILING LOWEST AMBIENT AIR TEMPERATURE AND SUBSTANTIALLY LESS THAN THE FREEZING TEMPERATURE OF WATER, AND INCLUDING A SECOND VAPORIZING MEANS, A SECOND HEAT ENGINE, AND AIR-COOLED SECOND CONDENSING MEANS CONNECTED BETWEEN THE EXHAUST OF SAID SECOND HEAT ENGINE AND THE INLET OF SAID SECOND VAPORIZING MEANS; SAID FIRST CONDENSING MEANS AND SAID SECOND VAPORIZING MEANS BEING IN HEAT EXCHANGE RELATION WHEREBY THE HEAT OF THE EXHAUST STEAM IS UTILIZED TO VAPORIZE SAID SECOND MEDIUM.
