ABSTRACT:
Solar collectors are supported for accurate alignment with the sun through all daylight hours, as guided by a tracking system employing a sensor for light level and subordinate sensors for two axis tracking, each of the subordinate sensors having a relatively long and thin band of view parallel to the axis of motion. Special coatings on the heat gathering element of the collector efficiently convert infrared, ultraviolet and, to some extent, gamma and cosmic rays into heat. In a system for generating electricity, collectors feed a heat transfer fluid to a heat transfer manifold where collector and fluid temperatures are monitored to control the rate of fluid flow. The fluid also circulates between the manifold and a plurality of heat storage containers. Heat from the containers is removed by another fluid that circulates through an electrical generating system employing a prime mover powered by the second fluid. During periods of continued generation, the system permits the second fluid to be reheated in only one heat storage container at a time, while the collectors regenerates spent heat storage containers.
