| 摘要 |
This invention deals with novel method and apparatus for 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. This achieves an advantageous natural vertical stability. The torque to produce angular deflection, and rotational motion is provided 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. The instant invention is ideally suited for maximization of solar energy focused by a low-profile concentrator array onto a receiver. Since there are no motors or mechanical linkages, the instant invention provides less costly and greater ease of manufacture. Dynamic motion can be controlled over a wide range of dimensions from nanometers to decimeters.
