Abstract
A solar collector utilizes multiple reflections of light passing down a tapered, pyramidal-type structure made of highly-reflective mirrored surfaces. A right-angled truncated reflective pyramidal structures have been discovered to have many properties which make them superior to existing concentrator geometries. The use of a tapered, pyramidal-type structure creates multiple reflections which appear at the collector output in the form of a Buckminster-Fullerene display, providing improved collector efficiency and amplification when compared to prior art “concentrators” of the Fresnel lens or parabola type.
