Abstract
Abstract A plurality of relatively small reflective panels, flat or curved, direct sunlight to an energy pickup which is approximately the size of one of the small reflective panels and are spaced three-dimensionally to utilize available space and support structures economically. Telescope-type drives tilt and rotate the panels individually or by selected groups to focus and maintain concentration of radiant or solar energy on the pickup during the day and seasonally. In one embodiment, energy from the sun is reflected from a first group of reflectors to a second group of reflectors that direct the energy down a tubular concentrator to an energy pickup. Each of the reflectors is curved about a single axis. The axes of the reflectors of the first group are oriented in a direction orthogonal to the direction of the axes of the reflectors of the second group. The first group of reflectors reflect energy in lines to the second group of reflectors, and the second group of reflectors direct the lines of energy received from the first group into concentrated narrow beams to the energy pickup.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
228 words
A solar energy concentrator system comprising: a reflecting concentrator having a main tubular member and a plurality of smaller tubular branches, an energy pickup device operatively connected to an energy utilization device, said main tubular member being substantially upright and having an open lower end directed to said energy pickup device, said branches extending upwardly at small acute angles from respective points spaced longitudinally along said main tubular member, said branches opening into said main tubular member, said main tubular member and said branches having highly polished reflective inner walls, a plurality of first reflectors, a plurality of second reflectors, different ones of said second reflectors being associated with different ones of said branches and being at a level higher than respective upper ends of respective ones of said branches, said first reflectors being associated with certain ones of said second reflectors and being positioned at levels below said respective second reflectors, each of said first and second reflectors having a reflecting surface, said first reflectors being rotated and tilted with respect to respective reference axes during a portion of each day to position said reflecting surfaces thereof for reflecting energy from the sun to respective ones of said second reflectors, and said second reflectors being oriented to reflect solar energy from respective ones of said first reflectors into said upper ends of respective ones of said branches.
