Title: Solar heat apparatus

Abstract: A solar energy device comprising a member adapted to contain a liquid and a lens for concentrating rays from the sun on a surface of the member. Cold liquid enters the member and heated liquid is extracted from it. A device produces relative movement between the lens and member surface in response to variations in temperature of the liquid in the member so as to move the member surface into and out of coincidence with the focal point of the lens. The device producing movement may include an element which expands and contracts in response to temperature variations.
