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.
