Abstract

Concentrated solar power with a field of heliostats has the potential to reach temperatures as high as 1500C, as required for industrial processes. We plan to accomplish this using heliostats on target-oriented mounts, with a mirror surfaces whose toroidal shape is changed throughout the day to maintain a focused disc images of the sun on a receiver. We have built a simple mechanism that deforms a rectangular mirror without the expense of dedicated motors or computer control. The heliostat’s slewbearing has a dual function of orienting the reflector to direct sunlight to the tower and also twisting the mirror shape.
