Abstract: A solar concentrator utilizes an arrangement of an outer reflective ring around a centrally located inner reflective cone to concentrate light. The reflective surface of the outer reflective ring is substantially 45 degrees from a transmitted light source. Light from the light source is reflected off of the outer reflective ring to produce a reflected light having a light reflective axis. The reflected light is directed toward the inner reflective cone and is reflected off of the reflective surface of the inner reflective cone as transmitted light toward alight receiver. The reflective surface of the inner reflective cone is configured at 45 degrees from the light reflective axis. The light receiver may convert the transmitted light into electricity or heat a fluid or other article. A solar tracker may be used to keep the central axis of the solar concentrator aligned with the sun.
