20090064993 | SOLAR ENERGY CONCENTRATOR - A solar concentrator having a concentrator element for collecting input light, a reflective component with a plurality of incremental steps for receiving the light and also for redirecting the light, and a waveguide including a plurality of incremental portions enabling collection and concentration of the light. | 03-12-2009 |
20090071467 | MULTI-JUNCTION SOLAR CELLS WITH A HOMOGENIZER SYSTEM AND COUPLED NON-IMAGING LIGHT CONCENTRATOR - The present embodiments provide methods and systems to homogenize illumination on a target. Some embodiments provide rotational symmetric dual-reflector solar concentrators that include a concave primary reflector with an aim-direction directed toward the sun to receive optical radiation in a far-field angle within an angle of acceptance and redirect radiation upward and centrally generating flux concentration, a secondary reflector positioned coaxial with said primary reflector to receive said redirected radiation and redirect radiation downward and centrally generating flux concentration solar rays, and a central target zone receiving said concentrated solar rays, where cross sections of said primary and secondary reflectors both further comprise a multiplicity of segments that establish a correspondence between pairs of segments, each of said segments of said primary reflector such as to image said angle of acceptance onto said corresponding segment of said secondary reflector to image onto said target zone. | 03-19-2009 |
20110155126 | WAVE GENERATED ENERGY FOCUSING LENS AND REFLECTOR FOR SOLAR CONCENTRATION, COLLECTION, AND HARNESSING - A novel method of concentrating solar energy using wave generators is disclosed. The systems and methods enable the collection of energy over large area at high efficiencies and the concentrating of energy at a target for use and transfer. | 06-30-2011 |
20110271954 | SOLAR CONCENTRATOR - A solar concentrator comprises an incidence surface, a first reflective curved surface corresponding to the incidence surface, a second reflective curved surface disposed in a center part of the incidence surface, and a concentrating part disposed in a center part of the first reflective curved surface and corresponding to the second reflective curved surface, wherein the incidence surface, the first reflective curved surface, the second reflective curved surface, and the concentrator include a substantially same material from each other. | 11-10-2011 |
20120031396 | Luminescent Solar Concentrator With Distributed Outcoupling Structures And Microoptical Elements - A luminescent solar concentrator including a light-guiding slab containing a luminescent material that generates light emissions in response to received sunlight, spaced-apart outcoupling structures that provide a distributed outcoupling of the light emissions through predetermined locations on one of the “broadside” (e.g., upper or lower) surfaces of the light-guiding slab, and optical elements positioned to redirect the outcoupled light emissions such that the light emissions are concentrated onto a predetermined target (e.g., a PV cell). Each optical element includes a collimating surface portion and optional returner surface. | 02-09-2012 |
20140318531 | DEVICE FOR CONCENTRATING ENERGY - The present invention relates to solar-energy engineering and can find application in solar power plants of the kind of “tracking saucer”, “pan” and “solar tower” and in other similar systems. | 10-30-2014 |

20100078012 | Half parabolic dish reflector with planar reflector solar smelter - Melting metals using solar energy is not new, but is new is making the technology ergonomic, and easy to use. Invented is a half-shell-parabolic-dish reflector, which has in front an adjustable flat planar reflector. When the sun is overhead, the sunlight reflects off the flat planar reflector to a half-shell-parabolic-dish, which redirects the light to a crucible for smelting metals, which is also the focus of the sunlight. The entire assembly rotates on top of a turntable, which can be steel wheel, floating on compressed air, bicycle wheels, or other suitable methods. The entire assembly rotates about a crucible located at the focal of the sun's rays. A smaller version of the smelter can be used for solar cooking. | 04-01-2010 |
20110005515 | Solar half parabolic shell smelter with a heliostat on a turntable - Developed is a solar cooker with triangle reflective sides. Above and below are two movable solar reflecting panels, that can be adjusted to focus light onto an invented frying pan using a glass lid, an insulating pad, and a surrounding plastic bag to trap solar light for cooking. The triangle reflective sides are used also to adjust and support the two movable solar reflecting panels via movable pegs. In the corners adjacent to the triangle sides, back reflective plate and reflective floor plate is an invented reflective equilateral triangle, to capture and reflect light towards the solar frying pan assembly. At night the entire solar cooker can be folded down to form a storage space. The entire solar cooker is foldable for shipping. (123 words). | 01-13-2011 |
20120037152 | Solar half parabolic shell smelter with a heliostat on a turntable - Invented is a solar smelter that also manufactures hot air or hot fluids. A curved parabolic-half-shell focuses the sun's rays unto a crucible, which is buried into the ground. Using a heliostat, the sunlight is reflected horizontally unto an interior reflective wall of the curved parabolic-half-shell. Surrounding the crucible is a thermal-mass with embedded pipes, that manufacture hot and compressed air, or heated gas or fluid. On top of the thermal-mass is a clear transparent-and-insulating-glazing that captures any stray solar rays, adding heat to the thermal-mass. At the foci of the parabolic-half-shell is a crucible for melting rocks, sand, glass or metals, or processing chemicals. | 02-16-2012 |
20150354856 | TROUGH COLLECTOR WITH CONCENTRATOR ARRANGEMENT - The invention relates to a trough collector with a primary concentrator, which concentrates solar radiation into a focal line region, with an arrangement for secondary concentration of the solar rays reflected by the primary concentrator, which arrangement concentrates the solar rays further into focal point regions. The arrangement for secondary concentration has a plurality of rows of secondary concentrators which have identical orientation in a row, but have differing orientation from row to row. Further, means are provided in order to keep one of the rows in the operating position and the other rows in a rest position. Thus, a range of the skew angle can be assigned to each of the rows and in the event of the change thereof, another row is brought into operating position. | 12-10-2015 |
