Solar energy collector

Claim 1

A solar energy collection system comprising: a. an elongated, evacuated, substantially cylindrical envelope of transparent material having an orifice at one end thereof; b. an elongated, substantially cylindrical, sealed container mounted within said envelope, one end of said container projecting through said orifice via an air-tight seal, said container being disposed at an angle with respect to horizontal, said end projecting through said envelope being located at the higher elevation; c. a vaporizeable liquid located within said container and concentrated at the lower elevation thereof, said fluid, upon vaporization, progressing toward the higher elevation of said container where said vapor gives up heat and condensation takes place; d. a plurality of axially-aligned, fin-like structures attached to and projecting from said container for enhancing the heat absorption of said container; e. an inverted, elongate, substantially bilaterially symmetrical, gull-wing shaped reflector located below and external to said envelope and extending for a substantial portion of the length of said envelope for receiving and reflecting incident solar radiation from an area wider than said envelope and for concentrating said radiation on said envelope; f. a first substantially planar conductive member affixed to the emergent portion of said container for conducting therefrom heat given off by the condensation of said vaporized liquid; g. a second substantially planar conductive member removably fastened to said first conductive member for conducting heat therefrom; and h. a fluid-carrying conduit affixed to said second conductive member for removing heat therefrom and transporting the extracted heat.
