NOVELTY - A solar blackbody waveguide for conversion of solar flux to heat energy, comprises solar arrays comprising solar collection cells attached to and supported by each solar tower, each solar collection cell attached to and provided with a mechanism for directing sunlight in parallel light rays, into a common light waveguide provided for its associated solar tower.    USE - The solar blackbody waveguide is for conversion of solar flux to heat energy (claimed), to heat a thermal working fluid, such as compressed air or water. It is as an air preheater to heat air for use in association with a combined cycle gas turbine (56); and a steam generator (59) for use in steam cycle turbine (57) plants, or other commercial or industrial processes requiring steam.    ADVANTAGE - The solar blackbody waveguide efficiently and effectively converts solar flux to heat energy.    DETAILED DESCRIPTION - A solar blackbody waveguide for conversion of solar flux to heat energy, comprises solar towers; and solar arrays comprising solar collection cells attached to and supported by each solar tower, each solar collection cell attached to and provided with a mechanism for directing sunlight in parallel light rays, into a common light waveguide provided for its associated solar tower, each common light waveguide entering into an interior of a hollow, lossy solar coil and guiding light rays to the interior of the lossy solar coil, the lossy solar coil located within an insulated pipeline, so that the lossy solar coil extends longitudinally within the insulated pipeline, each of the common light waveguides connected to an associated solar horn provided internally within the solar coil, to direct the light rays in one direction and approximately longitudinally into the hollow solar coil, where the light rays are absorbed by the solar coil and are converted to heat energy, and the pipeline provided internally with an annular space surrounding the outside of the solar coil, as a space through which working fluid circulates to remove the heat energy from the solar coil, and from which the working fluid can be removed for use as an energy source. An INDEPENDENT CLAIM is also included for a method of converting solar flux to heat energy employing a solar blackbody waveguide, comprising capturing light rays from the sun in solar cells that reflect the sunlight as parallel light rays into a series of common light waveguides; guiding the light rays through the common light waveguides to an interior of a hollow solar coil that is provided extending longitudinally inside an insulated pipeline; directing the light rays into the hollow solar coil approximately longitudinally within the hollow solar coil via solar horns that are provided within the hollow solar coil in association with each common light waveguide; converting light rays to heat energy by having the solar coil absorb the light rays; transferring the heat energy from the solar coil to a working fluid by circulating the working fluid from an upstream end to a downstream end of the pipeline through an annular space provided internally in the pipeline surrounding the outside of the solar coil; and removing the working fluid from the downstream end of the pipeline for use as a source of heat energy.
