Apparatus for concentration of solar radiation

Claim 1

An apparatus for converting solar radiation into high temperature heat energy wherein the solar radiation is directed vertically downward by means forming reflecting planes onto the surface of a fluid body rotating at constant angular velocity about its vertical axis; said reflecting planes being located upon a rotating gantry centered on the axis of the rotating fluid such that the rays reflected from the fluid surface are directed to another reflecting means located on said gantry so as to concentrate said rays upon a radiation to enthalpy exchanger located near means forming the focal point of said other reflecting means and wherein the reflectivity of the fluid is increased by a covering or partial covering of reflective particulate floating material, said gantry including means to enable said gantry to follow the sun in azimuth and upon which are mounted pivoted reflecting planes including means to enable said pivoted reflecting planes to follow the suns radiation in elevation to maintain the angle of incidence of the suns rays upon said rotating fluid surface equal to the angle between said surface and the vertical, and wherein the means for rotating the fluid is a mechanism which includes means to form a vessel containing a volume of fluid and having support means for rotating said vessel means about its' vertical axis, a multiplicity of wheels pressed substantially uniformly against the circumference of said vessel means; one or more of said wheels being rotated by a constant speed motor thus causing said vessel to rotate at constant revolutions per minute wherein said vessel support means is a fluid in a stationary tank, said fluid having a sufficient depth and density to float the rotating vessel means with its contents.
