Abstract: A solar energy desalination process utilizing solar radiation directly for the evaporation of salt water is described. Ambient air takes on water vapor as the air passes through an evaporative medium. It is then directed between a saline water-covered, solar absorbing surface and a solar collecting housing. The resulting heated and moisture-saturated air is cooled in a heat exchange means where condensation of fresh water occurs. Simultaneously, cool salt water is utilized as the cooling water in the heat exchange means, and takes on the heat of condensation given up by the condensing vapor. The heated salt water from the heat exchange means is partially directed over the solar absorbing surface, and at least a portion of it is also directed to wet the evaporative medium. Several optional sub-processes are described for operation of the system during periods of reduced insolation, and an alternative process is described for operation of the process on a floating platform.

Abstract: A method and apparatus for conserving waste energy by transferring waste heat from an internal combustion engine, solar energy or from any other source of waste heat energy of a temperature of 200.degree. F. or above to a carrier liquid includes conveying the heated carrier liquid to a heat exchanger, pressurizing a refrigerant by heating the refrigerant with heat energy extracted from the heated carrier liquid and performing work with the pressurized refrigerant. The preferred embodiments include a modified Rankine-Sterling cycle engine and a dual absorption generator system.

Abstract: The structure disclosed includes an air supported transparent membrane which encloses a solar collector unit. The solar unit includes a solar collector element and two angled walls that support and position the element. The solar collector element receives and absorbs solar radiation and provides heat to a circulating fluid. The support walls extend forwardly and outwardly from the collector element and have reflecting facing surfaces to increase the amount of radiation falling on the element. The walls extend rearwardly of the element to define a chamber in which small rocks are stored to provide heat storage. The transparent membrane creates a greenhouse effect within the chamber defined by the membrane, increasing the operating temperature and thus the conversion efficiency of the solar collector element. Furthermore, the air supported membrane protects the solar collector unit from wind loading.
