-17- A DESALINATION APPARATUS WITH POWER GENERATION ABSTRACT A desalination apparatus with power generation is disclosed comprising an evaporating means 14 and a conden- sing means 26. Conduit means 18 connect the evaporator means 14 and said condensing means 26 in a closed loop with the vapors of said evaporator 14 being coupled thermally with said condenser means 26. Temperature differential means comprise the temperature of the ocean water at the ocean surface providing heat input into said evaporator means 14 whereas cold ocean water pumped from the depths of the ocean provides the cooling means to said condenser 26. The difference in temperature between this warm ocean water at the ocean surface and the cold water from the depths of the ocean thus provides the heating and cooling means for powering said apparatus, Evaporation in the condenser 26 and condensing in the said condenser 26 when the air has been removed from the apparatus by means of a vacuum pump means 24 leaves only water vapor in the system. This evaporation and subsequent condensing of the vapors from the ocean water, which are essentially low temperature steam, results in a mass flow of vapors from the evaporator means 14 to the condenser means 26 through the conduit means 18 connecting same. These vapors when condensed in the con- denser means 26 become distilled or desalinated water since only water vapors are carried through the apparatus and the salt, minerals, etc. are retained in the ocean water in the evaporator 14.
