Patent attributes
A solar concentrator includes a mirror 24 having a frame 27 connected with a lever 55, a train 36 supporting the frame 27 and the lever 55, a first control cable 28 connected with the frame 27, and a second control cable 30 connected with the lever 55. A first locomotive 35 moves the train along a curvilinear path to keep the mirror 24 opposite the sun. The first control cable 28 controls pitch of the mirror 24 and the second control cable 30 controls yaw of the mirror 24. When a concentrator includes a plurality of mirrors 24 they are preferably controlled collectively by pulling all of the first control cables 28 with one motor to control pitch and by pulling all of the second control cables 30 with one motor to control yaw. Sunlight focused on the receiver 20 preferably boils water to form steam that is transmitted to a turbine connected to a generator for producing electricity.
