Abstract
A mirror collector having a generally parabolic surface terminating near the vertex in a circular or cylindrical curve, an evacuated cylindrical heat entrapment tube composed of a clear glass for energy admission and an elongated, U-shaped heat collector tube centrally located in the heat entrapment tube for passing an inner fluid to be heated. The U-shaped tube is constructed of copper with a selective absorption coating for receiving heat and positioned so that the mirror collector concentrates substantially all incoming energy upon the central heat collector tube for providing a concentration factor of about four (4).
