Abstract: Method and apparatus are presented for the mass production manufacturing of planar mirrors inside transparent micro balls circumscribed by lubricated bearings for solar energy concentration and related applications such as optical switches, etc. These bearings permit rotational alignment of the balls with minimal friction. The preferred mass production process utilizes photolithography in an optical microlithographic photoresist process. The micro-balls are in the size range of ˜1 micron (1×10-6 m) to 1000 microns (1 mm). The micro-balls vary in geometry from spheres to cylinders to oblate ellipsoids to disks. The term “elements” is used to encompass all these shapes, which have one thing in common—a flat specularly reflecting mirrored surface.

Abstract: This invention deals with novel method and apparatus for positioning and motion control of the optical elements (mirrors and lenses) of a Fresnel solar concentrator tracking array which approximately eliminates gravitational torque by use of a central universal pivot or gimbals. Linkage torque is produced by induced and/or permanent dipole coupling to an electronic grid to produce angular deflection, and rotational motion that is enhanced by the presence of highly polarizable material. This system is ideally suited for maximization of solar energy focused by the array onto a receiver. Since there are no mechanical linkages, the instant invention is applicable for fabrication from the mini- to the nano-technology realm. The elimination of gravitational torque by balancing the optical elements on a universal pivot or gimbals greatly reduces the power required for the optical elements to track the sun and focus sunlight onto a receiver.

Abstract: It is becoming increasingly imperative to harness solar energy due to the ever growing shortage of conventional energy sources. The instant invention is concerned with method and apparatus for the stable alignment of mirrors inside transparent micro balls with the plane of the mirror perpendicular to the aligning electric field for solar energy concentration and related applications such as optical switches, etc. Coupling of an applied perpendicular electric field with the induced dipole in a mirrored ball results in an unstable orientation. The instant invention circumvents this problem so that a stable orientation is accomplished, resulting in an increase in the percentage of incident light that is reflected to the receiver. Broadly, this invention deals with novel concepts used for alignment in the focusing of light wherever mirrors are used for focusing such as for solar propulsion assist, illumination and projection of light, optical switching, etc.

Abstract: Due to an ever growing shortage of conventional energy sources, there is an increasingly intense interest in harnessing solar energy. This invention deals with method and apparatus for the direct conversion of solar energy to alternating current power by an active spinning mini-optics system. A limiting factor in the utilization of solar energy in the past has been the high cost of power conversion from dc to ac. By directly producing alternating current power, this invention substantially reduces the cost of generating photovoltaic electricity. This system utilizes a dynamic spinning ensemble of mini-mirrors to both concentrate and modulate rays from the sun onto a photovoltaic collector array. The focusing with superimposed spinning action produces single phase and multiphase alternating current (ac) with substantially higher power output than the direct current (dc) power resulting from the direct incidence of sunlight on the photovoltaic collector.

Method and apparatus are presented for coupling to a transparent sheet with an embedded array of preformed or formable mirrored micro-balls for use in a solar energy concentrator, and functionally similar applications such as optical switches and solar rocket assist. Mirrored micro-balls and particulate formable mirrors in cells are covered with a thin spherical shell of lubricating liquid so that they are free to rotate in an almost frictionless encapsulation in the sheet. Induced polarization electric or magnetic dipoles in the mirrors provide a method of controlling the alignment of the mirrored balls. Electrophoretically and magnetophoretically forming mirrors in situ on a rigid surface in a rotatable cell are also disclosed.

Abstract: This invention deals with the broad general concept for dynamic reflection, illumination and direct image projection. A mini-optics reflection and focussing system is presented that ranges from interior illumination, to exterior illumination, to large scale space based illumination, to ordinary and to telescopic image formation. It can be used both as a source of illumination, and to project images, figures, and the written word. This system has broad applications such as dynamic full color displays. Its use of a novel induced dipole coupling for rotation of planar mirrors lets it operate with greater simplicity and efficiency than other display devices. Furthermore in its capacity as a high altitude active reflector of solar radiation, it can be utilized to supply illumination, energy, and provide climate control.

Abstract: This invention deals with novel method and apparatus for positioning and motion control by rapid-response motorless linear motion, angular deflection, and continuous rotational motion utilizing the force due to electrons, ions, and/or neutrals. 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 over a wide range of dimensions and signal bandwidth with independent amplitude and frequency modulation. Since there are no internal moving parts, the instant invention is the most adapted for fabrication at the micro and nanotechnology realms. Furthermore it provides less costly and greater ease of manufacture from the nano-to the macro-realm.

Abstract: Method and apparatus are presented for manufacturing transparent mirrored spheroidal mini-balls for solar energy and related applications such as optical switches. For these applications it is imperative to provide accurate specular reflection from the mirror. Various means are described for maintaining the desired mirror flatness and avoiding warping, buckling, etc. of the mirror surface during manufacture. The mini-balls are in the size range of 4 microns (4×10?6 m) to 10 centimeters (10?1 m), and are transparent in at least one hemisphere. They preferably have a reflecting mid-plane mirror, though they can also be mirrored on a flat top of the ball.
