Abstract
Abstract An apparatus for collecting solar energy, the apparatus including a parabola shaped reflector around a pipe enclosed in a glass tube, the pipe being located at the focal point of the parabola shaped reflector, so that sunlight rays are reflected thereagainst, so to concentrate their heat thereagainst, the pipe extending outwardly of opposite ends of the reflector, so that water passing through the pipe is thus heated for practical uses, and the reflector being rotatable, so to follow the path of the sun, in order to obtain maximum efficiency therefrom.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
186 words
A solar concentrator, comprising in combination, an elongated reflector, which is a parabola cross-sectional shape, a reflective material on an inner surface of said reflector, a pipe extending along a longitudinal axis of said reflector and being located along a focal point of said reflector, and means for rotating said reflector in order to follow a path of the sun; said pipe having a portion thereof extending within said reflector, a glass tube enclosing said portion, an outwardly extending sleeve integral with each end wall of said reflector, said sleeves being axially aligned, said pipe extending through said sleeves, said sleeves being supported within bearings mounted in stanchions stationarily placed upon a supporting surface, one said sleeve having a gear secured thereto, said gear engaging a gear mounted on a shaft of an electric motor, and a portion of said pipe contained within said reflector being diametrically enlarged at one end, said pipe portion, accordingly, being conical in configuration, said diametrically enlarged end of said pipe portion being located adjacent an end of said pipe that forms an entry for cold water passing through said pipe.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
30 words
The combination as set forth in claim 1, wherein a clear glass encloses a top of said reflector, said glass holding radiant heat from escaping upwardly out of said reflector.
