Self ballasted celestial tracking apparatus |
摘要 |
The invention is a wind resistant celestial tracking apparatus that uses gravitational forces acting on the moving elements of the structure to provide overturning resistance. A molded self curing compound, such as reinforced concrete, is used as the structural material that provides the mass, and thus the gravitational overturning resistance that reduces or eliminates the need for a massive ballasted or dug-in foundation. The combination of these features potentially lowers cost significantly over that of tracking apparatuses found in prior art. The invention is appropriate for use in any celestial tracking application with any number of axes of motion, but is particularly useful in two axis solar energy collection systems. |
