<p>A method and an apparatus for desalination and/or purification of water, comprising a buoyant enclosure having restricting side walls (2, 2') spanned by an upper wall (1). The enclosure is partly or completely immersed in water, the restricting side walls (2, 2') being arranged to suspend same floating on a water surface. The enclosure is provided with air inlets (5, 5'), and an air stream is forced by means of wind force, wave energy and/or solar energy through the enclosure to a cooler (8), from which the condensate is transferred to a storage tank (19) or similar. A second and lower wall surface is suspended floating adjacent to the water surface, but below same, arranged to absorb heat imposed by solar energy. The enclosure is advantageously arranged to partly cover a beach, washed by waves, to obtain an increased evaporization. By arranging the upper wall with a number of lense elements, incoming solar rays are concentrated to the surface to be heated. A solar heated stack is advantageously arranged connected to the air outlet from the cooler (8), thereby increasing the air flow rate within the enclosure. Rain water, collected on the outer surface of the upper wall, is diverted through a substantially centrally located outlet via a conduit to the storage tank (19) used for the condensate.</p> |
