A ground-based tracking heliostat array comprises a first plurality of elongate row mounts. The elongate row mounts are positioned at least partially between, and are supported by, a first side bracket and a second side bracket. The row mounts are rotatable in a first axis. The array further comprises a plurality of optical elements that are mounted to one or more of the elongate row mounts. The array further comprises a linkage that is mechanically coupled to a first plurality of elongate row mounts. Movement of the linkage causes the first plurality of elongate row mounts to simultaneously rotate in the first axis. The array further comprises a motor configured to move the linkage.
PRIORITY APPLICATIONS
This application claims the benefit of U.S. Provisional Patent Application 60/490,746 (filed 28 Jul. 2003) and U.S. Provisional Patent Application 60/516,025 (filed 31 Oct. 2003). The entire disclosure of both of these priority applications is hereby incorporated by reference herein.
This invention deals with novel method and apparatus for positioning and motion control of a solar cell system that tracks the sun or other light source. This achieves an advantageous increase in output power. The torque to produce angular deflection, and rotational motion is provided separately by an induced and/or permanent dipole coupling to an electronic grid. Thus forces and torques are produced without the use of internal moving parts such as in motors. The instant invention exceeds the capability of conventional systems. It is suited for maximization of solar energy with an ideally low-profile tracking solar cell array. Since there are no motors or other heavy and expensive equipment, the instant invention provides less costly and greater ease of manufacture, transportation, and installation. Dynamic motion can be controlled over a wide range of dimensions from micrometers to decimeters.
Rectangular PV modules (6) are mounted on a building roof (4) by mounting stands that are distributed in rows and columns. Each stand comprises a base plate (10) that rests on the building roof (4) and first and second brackets (12, 14) of different height attached to opposite ends of the base plate (10). Each bracket (12, 14) has dual members for supporting two different PV modules (6), and each PV module (6) has a mounting pin (84) adjacent to each of its four corners. Each module (6) is supported by attachment of two of its mounting pins (84) to different first brackets (12), whereby the modules (6) and their supporting stands are able to resist uplift forces resulting from high velocity winds without the base plates (10) being physically attached to the supporting roof structure (4). Preferably the second brackets (14) have a telescoping construction that permits their effective height to vary from less than to substantially the same as that of the first brackets (12).
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 wherein the elements are suspended with the center of mass 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 separately by an electric wind force due to electrons, ions, and/or neutrals; or in combination with an induced and/or permanent dipole coupling to an electronic grid. Thus forces and torques are produced without the use of internal moving parts such as in motors. The instant invention exceeds the capability of conventional systems. It is ideally suited for maximization of solar energy focused by a low-profile concentrator array onto a receiver. Since there are no internal moving parts, 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.
A roadway system and method for energy generation and distribution are presented. This system allows a geothermal infrastructure to be tied into the roadway system electricity grid. The geothermal infrastructure may include energy exchangers that are electrically connected to the roadway system electricity grid. By connecting the energy exchangers electrically to the roadway system electricity grid, the energy exchangers may be powered by solar and/or wind generating devices. In one embodiment of the invention, a roadway system for energy generation and distribution comprises a plurality of energy harnessing devices (e.g., solar and/or wind generating devices). The roadway system electricity grid is configured for mass distribution of electricity. The energy exchangers are configured to electrically connect to the roadway system electricity grid. Each of substantially all of the energy harnessing devices, is electrically connected to the roadway system electricity grid and positioned on part of one of the roads.
Creating a large fleet of vehicles, which gather wind energy and generate wind generated energy, such as electricity, is impeded by the cost to an individual vehicle owner. Accordingly, a system and corresponding method to gather wind energy and deposit stored wind generated energy for system credit is provided. The present invention includes a vehicle-based wind energy gathering device to gather wind energy and generate wind generated energy, a vehicle-based energy storage system, electrically coupled to the wind energy gathering device, to store wind generated energy, and means for depositing the stored wind generated energy for system credit. As such, individual vehicle owners have an incentive to participate in gathering wind energy and depositing wind generated energy, such as electricity. By taking advantage of potentially millions of participants and participating vehicles, the present invention creates a format for generating energy from multiple forms of wind energy on a wide-scale.
