Abstract
Abstract A solar energy collector having a body of foamed plastic and a surface configuration of generally semicylindrical recesses in closely spaced parallel relationship, the surface of said recesses being covered with reflective or absorptive foil to reflect or transmit solar energy to receiving devices such a fluid conduits or solar cells. The collector is made by laying a plurality of half-pipes into a frame, covering them with foil, pouring curable foam plastic over the pipes and removing the composite from the pipes. The receiving devices are then mounted in the recesses and interconnected.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
A method for manufacturing a solar energy collector comprising: providing a flat base, laying over said base a plurality of generally semicylindrical male mold portions in closely spaced parallel relationship, placing a frame around said mold portions and extending upwardly from said base, covering said male mold portions with a layer of foil shaped in conformity therewith, pouring a curable foam plastic mix into said frame over said foil and curing said plastic mix, removing the resultant composite of frame, plastic and foil from said male mold portions and base, and providing solar energy receiving means within the recesses in said composite which were formed by said male mold portions.
Claim 2
Independent Claim
110 words
A method for manufacturing a solar energy collector comprising: providing a flat base, laying over said base a plurality of generally semicylindrical male mold portions in closely spaced parallel relationship, placing a frame around said mold portions and extending upwardly from said base, covering said male mold portions with a layer of foil shaped in conformity therewith, pouring a curable foam plastic mix into said frame over said foil and curing said plastic mix, removing the resultant composite of frame, plastic and foil from said male mold portions and base, and providing solar energy receiving means within the recesses in said composite which were formed by said male mold portions.
Claim 3
Dependent Claim
22 words
A method as defined in claim 1 and further including the step of adhering a backing sheet to the cured plastic foam.
Claim 4
Dependent Claim
28 words
A method as defined in claim 1 wherein providing said solar energy receiving means includes mounting pipes extending longitudinally through said recesses at approximately the focal points thereof.
Claim 5
Dependent Claim
24 words
A method as defined in claim 1 wherein providing said solar energy receiving means includes mounting solar cells in the bottoms of said recesses.
Claim 6
Dependent Claim
25 words
