ABSTRACT:
A highly polarizable high dielectric constant positioning and motion control of the elements (approximately planar mirrors) of a Fresnel reflector solar concentrator tracking heliostat array wherein the elements are suspended with the center of mass above the swivel point, below the swivel point, or have an internal-swivel. The torque to produce angular deflection, and rotational motion is provided by induced and/or permanent dipole coupling to an electronic grid. The force interaction is greatly enhanced by securing a high dielectric material adjacent to each mirror. Thus forces and torques are produced without the use of motors. This allows maximization of solar energy focused by a low-profile concentrator array onto a receiver. Dynamic motion can be controlled over a wide range of dimensions from nanometers to decimeters.
