<p>Desalination apparatus with power generation comprising an evaporating means (14) and a condensing 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 condenser 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). </p> |
