Abstract
Abstract This disclosure pertains to tanks, operated in pairs disposed above the surface of the earth. Each is adapted with sunshading deflectors selectively operated so as to permit the air contained within one such tank to be heated and thus elevated in pressure, by the rays of the sun. A receiving tank, disposed below the surface of the earth, collects the pressurized air and enables the cooling thereof. Condensation occurs while the pressure level within the receiving tank is elevated. A plurality of such units comprising above ground pairs of tanks and below ground cooled receiving tanks are arranged in a series circuit so as to increase the available air pressure at the last receiving tank. A centralized condensate tank collects all the water condensed within each receiving tank and utilizes the elevated air pressure therewithin to discharge the water as required. The air pressure at the last receiving tank may be utilized to drive a motor which in turn can operate an electric generator.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
305 words
A solar energy operated air compressor and condenser comprising at least two tanks, said at least two tanks being disposed above the grade of the earth and to the sun's rays, a first receiving tank, said first receiving tank being disposed below said grade and shilded from said sun's rays, means to alternately shield each of said at least two tanks from said sun's rays, first means to communicate compressed air from within said each of said at least two tanks to within said first receiving tank when the pressure level within said each of said at least two tanks exceeds the pressure level within said first receiving tank, a condensate tank, said condensate tank being disposed below said grade, first means to drain condensate water from said first receiving tank into said condensate tank when said condensate water reaches a pre-determined level within said first receiving tank, a first heating tank, said first heating tank being disposed above said grade and to said sun's rays, second means to communicate compressed air from within said first receiving tank to within said first heating tank when said pressure level within said first receiving tank exceeds the pressure level within said first heating tank, a second receiving tank, said second receiving tank being disposed below said grade and shielded from said sun's rays, third means to communicate said compressed air within said first heating tank to within said second receiving tank when said pressure level within said first heating tank exceeds the pressure level within said second receiving tank, second means to drain condensate water from said second receiving tank into said condensate tank when said condensate water within said second receiving tank reaches a pre-determined height within said second receiving tank, means to supply atmospheric air to within said each of said at least two tanks.
Claim 2
Dependent Claim
305 words
A solar energy operated air compressor and condenser comprising at least two tanks, said at least two tanks being disposed above the grade of the earth and to the sun's rays, a first receiving tank, said first receiving tank being disposed below said grade and shilded from said sun's rays, means to alternately shield each of said at least two tanks from said sun's rays, first means to communicate compressed air from within said each of said at least two tanks to within said first receiving tank when the pressure level within said each of said at least two tanks exceeds the pressure level within said first receiving tank, a condensate tank, said condensate tank being disposed below said grade, first means to drain condensate water from said first receiving tank into said condensate tank when said condensate water reaches a pre-determined level within said first receiving tank, a first heating tank, said first heating tank being disposed above said grade and to said sun's rays, second means to communicate compressed air from within said first receiving tank to within said first heating tank when said pressure level within said first receiving tank exceeds the pressure level within said first heating tank, a second receiving tank, said second receiving tank being disposed below said grade and shielded from said sun's rays, third means to communicate said compressed air within said first heating tank to within said second receiving tank when said pressure level within said first heating tank exceeds the pressure level within said second receiving tank, second means to drain condensate water from said second receiving tank into said condensate tank when said condensate water within said second receiving tank reaches a pre-determined height within said second receiving tank, means to supply atmospheric air to within said each of said at least two tanks.
Claim 3
Dependent Claim
