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 a higher efficiency in converting the incoming solar...
