ABSTRACT:
This invention deals with novel method and apparatus for positioning and motion control of the elements (mirrors) of a Fresnel reflector solar concentrator tracking heliostat array by induced and/or permanent dipole coupling to an electronic grid to produce angular deflection, and rotational motion. Thus forces and torques are produced without the use of internal moving parts. Control is achieved without recourse to magnetic fields, by means of high electric fields which may be attained at relatively low voltages. At low voltages, the instant invention exceeds the capability of conventional systems. It can perform dynamic motion control with independent amplitude and frequency modulation. It is ideally suited for maximization of solar energy focused by the array onto a receiver. Since there are no internal moving parts, the instant invention is the most adapted for fabrication from the mini- to the microtechnology realm. Furthermore it provides less costly and greater ease of manufacture from the mini- to the micro-realm.
