Apparatus and Method for High Solar Concentration using a Field of Twisting Heliostats
This technology is a twisting heliostat that automatically adjusts its reflector’s shape throughout the day to adapt to changes in the sun’s relative position to the heliostat field. It uses closed loop tracking to ensure that that light reflected from each twisted heliostat is centered on a target point. This design allows for higher concentration...
