Abstract
Abstract A highly efficient solar focusing means being hollow and in semi-cylindrical or arcuate shape, the surface of which has such fine menisci as to act like convex lenses to focus solar rays towards the center of the focusing body, irrespective of the position of the sun, where a solar energy conversion device is located and further acts to disperse light reflected thereonto from the solar energy conversion device. The focusing body can assume several shapes and thus can be used for roofing of a building, such as a house, or the like, and still be aesthetically pleasing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
211 words
A solar energy focusing means comprising: a hollow solar energy focusing body, having a transverse cross-section which includes a substantial fraction of a plane figure, said focusing body straddling a portion of a solar energy conversion device so that solar energy is incident upon said focusing body prior to being incident upon such conversion device portion; a multiplicity of fine menisci defined in said solar energy focusing body to be in a plurality of groups with spacing between said groups, said menisci being ground and angled to define a plurality of biconvex lenses for incident solar energy and a plurality of biconcave lenses for solar energy which is reflected from said solar energy conversion device, said plurality of bi-convex lenses having a plurality of focuses on said focusing body to focus incident solar rays in multiple beams onto such conversion device portion in the manner of convex lenses, said multiple focuses applying multiple focused beams onto the solar energy conversion device at all times irrespective of the position of the sun so that the sun need not be tracked, said concave lenses dispersing said reflected solar energy so that said focusing body has an outward overall coloring corresponding to the coloring of such conversion device portion straddled by said focusing body.
