Abstract
Abstract A solar energy black body collector is disclosed that gathers the sun's radiant forms of energy, transforms the energy to heat energy and transfers this energy to a medium fluid (air). The energy absorbing structure consists of a cell layer (secondary black body collector) and a flat plate (primary black body collector) almost perpendicular to each other. This combined structure collects the sun's rays from any inbound angle and reduces, to a minimum, reflected rays out of the black body collector frontal area. The black body collector structure is mounted between a transparent (to light wave energy) front panel and an opaque rear panel. The entire unit is hermetically sealed to the outside elements and is a completed unit ready for service.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
An omnidirectional solar collector comprising (a) a transparent sheet pervious to shortwave solar radiation but impervious to longwave radiation, (b) a primary collector comprising a plurality of parallel tubes, including a means on the surface for absorbing shortwave solar radiation and re-radiating the same as longwave radiation, and (c) a secondary collector comprising a layer of cells situated between said transparent sheet and said primary collector with respective air spaces on either side of said layer of cells, a first one of said air spaces separating said cell layer from said primary collector, cell walls in said cell layer being oriented generally perpendicular to the surface of said primary collector and being open to both sides of said layer so that the interior of each cell is exposed to both of said first and second air spaces, said cell walls including means absorbing shortwave solar radiation and re-radiating the same as longwave radiation.
Claim 2
Dependent Claim
153 words
An omnidirectional solar collector comprising (a) a transparent sheet pervious to shortwave solar radiation but impervious to longwave radiation, (b) a primary collector comprising a plurality of parallel tubes, including a means on the surface for absorbing shortwave solar radiation and re-radiating the same as longwave radiation, and (c) a secondary collector comprising a layer of cells situated between said transparent sheet and said primary collector with respective air spaces on either side of said layer of cells, a first one of said air spaces separating said cell layer from said primary collector, cell walls in said cell layer being oriented generally perpendicular to the surface of said primary collector and being open to both sides of said layer so that the interior of each cell is exposed to both of said first and second air spaces, said cell walls including means absorbing shortwave solar radiation and re-radiating the same as longwave radiation.
Claim 3
Dependent Claim
24 words
The solar collector of claim 1 wherein the cells of said cell layer are in the shape of right cylinders open at both ends.
Claim 4
Dependent Claim
42 words
The solar collector of claim 1 wherein the transparent sheet, the primary collector and the secondary collector are supported in a housing structure, the housing structure having a cold air intake and a hot air exhaust in communication with said air spaces.
Claim 5
Dependent Claim
23 words
The solar collector of claim 3 wherein said layer of cells is interposed between said first air space and said hot air exhaust.
Claim 6
Dependent Claim
31 words
The solar collector of claim 4 wherein the communication between said cold air intake and said first and second air spaces is free of any interposition of said layer of cells.
