Abstract: A solar heating apparatus that uses a Fresnel lens to concentrate solar radiation onto the top surface of a heat conductor for the purpose of heating a transient fluid or gas. The apparatus includes a conductor, a frame, and a Fresnel lens. The conductor and Fresnel lens are secured to the frame so that the conductor is within the optimum focal position of the Fresnel lens. A helical conduit around the periphery of the core of the conductor with a larger diameter than the diameter of the inlet and outlet conduits of the conductor provides additional residence time for the fluid or gas. A number of apparatus may be joined together in a series of rows so that the fluid or gas may be heated to an extremely high temperature. The heated fluid or gas may be used to power a turbine for the generation of electrical power or to supply process heat for commericial or industrial use.
