Alternating still desalination

Claim 1

THE METHOD OF CONVERTING SEA WATER TO FRESH WATER, WHICH CONSISTS IN: INSTITUTING THE STEP OF SIMULTANEOUSLY GENERATING VAPOR FROM SEA WATER AND CONDENSING FRESH WATER VAPOR WHICH COMPRISES INCREASING THE VAPOR SPACE ABOVE AN UPWARDLY CONFINED BODY OF SEA WATER AND SIMULTANEOUSLY HEATING THE CONFINED BODY OF SEA WATER BY CONDUCTING HEAT FROM THE VAPOR AND CONDENSATE IN A FLUID TYPE HEAT EXCHANGER HAVING AN INLET AND AN OUTLET AND DISPOSED IN INTIMATE HEAT EXCHANGE RELATION WITH SAID CONFINED BODY OF SEA WATER, AND SIMULTANEOUSLY DECREASING THE VAPOR SPACE ABOVE A SECOND UPWARDLY CONFINED BODY OF SEA WATER AND SIMULTANEOUSLY CONDUCTING VAPOR FROM THE LAST MENTIONED SPACE TO THE INLET OF THE HEAT EXCHANGER; THEREAFTER INSTIUTING THE STEP OF SIMULTANEOUSLY GENERATING VAPOR FROM THE SEA WATER OF THE SECOND MENTIONED CONFINED BODY OF SEA WATER AND CONDENSING FRESH WATER WHICH COMPRISES INCREASING THE VAPOR SPACE ABOVE THE SECOND MENTIONED CONFINED BODY OF SEA WATER AND SIMULTANEOUSLY HEATING THE SECOND MENTIONED CONFINED BODY OF SEA WATER BY CONDUCTING HEAT FROM THE VAPOR AND CONDENSATE IN A FLUID TYPE HEAT EXCHANGER HAVING AN INLET AND AN OUTLET AND DISPOSED IN INTIMATE HEAT EXCHANGE RELATION WITH THE SECOND MENTIONED CONFINED BODY OF SEA WATER, AND SIMULTANEOUSLY DECREASING THE VAPOR SPACE ABOVE THE FIRST MENTIONED CONFINED BODY OF SEA WATER AND SIMULTANEOUSLY CONDUCTING VAPOR FROM THE FIRST MENTIONED CONFINED SPACE TO THE INLET OF THE SECOND MENTIONED HEAT EXCHANGER, CAUSING ALTERNATING INSTITUTION OF SAID STEPS; IMPEDING THE FLOW OF VAPOR FROM THE SECOND MENTIONED HEAT EXCHANGER TO THE FIRST MENTIONED CONFINED SPACE WHILE THE FIRST MENTIONED STEP IS TAKING PLACE; IMPEDING THE FLOW OF VAPOR FROM THE FIRST MENTIONED HEAT EXCHANGER TO THE SECOND MENTIONED CONFINED SPACE WHILE THE SECOND STEP IS TAKING PLACE; CONDUCTING WATER FROM THE OUTLETS OF THE HEAT EXCHANGERS THROUGH CONDUIT MEANS; AND IMPEDING THE FLOW OF WATER THROUGH SAID CONDUIT MEANS.
