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...

Actively Focused Heliostat with Mechanically Coupled Shape Change
This invention is a heliostat that has its toroidal reflector continuously altered through the day. A simple mechanical coupling is used to change the reflector shape over the course of the day. Dual-axis mounts were found to maximize capability. In this way, the heliostat realizes the highest possible concentration of sunlight.
This model also reduces...

Target Axis Heliostat with Mechanically Coupled Reflector Deformation
This technology utilizes a mechanical coupling system that changes the shape of the reflectors on the heliostat throughout the day. In doing so, the incoming light from the sun is always focused to a sharp image. This increases the temperature at the device’s receiver and allows for higher efficiency in converting the incoming solar energy to...
