Dumbeck, R F

The invention comprises efficient means for conversion of solar energy into stored heat by means of a circulating fluid, preferably silicone oil, so that temperatures higher than 100* C. May be efficiently attained. The fluid is passed through a helical conduit pipe of a blackened metal such as anodized aluminum or copper upon which a stainless steel semi-cylindrical reflector surface concentrates solar energy. There is a movable cleaning rig with a silicone oil wetted pad array that passes periodically over the stainless steel surface to keep it free of dirt and film. Also the transparent cover of a compartment in which the collector is mounted is periodically cleaned. Preferably the collector array is mounted in a pit in the ground to retain ground heat and prevent convection and radiation losses , and the reflector is moved to track the sun position.
