Abstract
Abstract A solar powered distilling device, and more particularly, a device wherein a plurality of convex lenses concentrate the heat energy of sunlight to heat and vaporize a quantity of water, said water vapor rising from a vaporization chamber to a cooling chamber by virtue of spaces provided between troughs located there between, the water vapor is cooled by virtue of the circulating air in an air cooling chamber condensing the vapor into water droplets; said droplets being collected in said collection troughs provided for this purpose.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
208 words
A distilling device powered by solar energy comprising: a housing for defining a vaporization chamber; a transparent cover on said housing; a transparent condensation plate mounted on said housing to define a pair of separated chambers including a cooling air chamber defined by one side of said plate and said cover, said vaporization chamber being defined by the other side of said plate and said housing; fluid inlet means on said housing for conducting fluid to be vaporized into said vaporization chamber; a plurality of solar energy focusing lenses on said cover focusing solar energy through said cooling air chamber and said condensation plate onto the fluid located in said vaporization chamber to form vapor; air inlet means on said cover for conducting cooling air into said cooling air chamber to contact said condensation plate one side for maintaining said plate at a temperature below the condensation temperature of the fluid in said vaporization chamber so that vapor formed in said vaporization chamber is condensed into condensate upon contact with said plate other side; a condensate collecting means connected to said housing for collecting for condensate formed on said condensation plate; and outlet means connected to said condensate collecting means for withdrawing the collected condensate from said housing.
