| 20100294266 | CONCENTRATED SOLAR THERMAL ENERGY COLLECTION DEVICE - This patent application discloses structure and use of concentrated solar thermal energy collector modules, installed individually, or in an array configuration. Because of the modular design, the individual collector modules are easier to manufacture, transport, and install. Systems of varying scale and varying thermal output may be built by custom arrangement of individual collector modules. Each module comprises a tiltable mirror array, a support frame for the mirror array, a heat absorption tube at a focal point of the mirror array, a parabolic mirror concentrator above the heat absorption tube, and two transparent protective panels coupled between the mirror concentrator with the support frame. The heat absorption tube may be a sealed heat tube, or a fluid circulation conduit. The mirrors are configured to be positionally adjusted to improve focusing of thermal energy and/or to track the changing position of the sun. | 11-25-2010 |
| 20140158114 | SOLAR LIGHT COLLECTING MIRROR AND SOLAR THERMAL POWER GENERATION SYSTEM HAVING SOLAR LIGHT COLLECTING MIRROR - A solar light collecting mirror includes a reflective section which is elastically deformable, and a frame which is elastically deformable and configured to support the reflective section. A central portion of the reflective section is positionally fixed in X and Y directions of the reflective section. A relative position in a Z direction between the central portion of the reflective section and a peripheral portion of the reflective section is changeable. The peripheral portion of the reflective section is not positionally fixed in the X and Y directions. The frame includes warp members which radially extend from a position corresponding to the central portion of the reflective section. And the reflective section is configured to deform elastically together with the frame so as to change the relative position in the Z direction between the central portion and the peripheral portion, whereby a concave mirror structure is obtained. | 06-12-2014 |

| 20090114213 | SOLAR CONCENTRATOR WITH SQUARE MIRRORS - The present invention is a solar concentrator system incorporating a square primary mirror, a square secondary mirror, and an optical receiver. The square secondary mirror provides highly efficient throughput of light in combination with the square primary mirror, with minimal shading. Manufacturing features may be incorporated into the square secondary mirror to assist in simplifying fabrication issues and assembly steps related to its non-circular shape. An optional heat shield around the optical receiver may be included, further enhancing performance of the solar concentrator system. | 05-07-2009 |

| 20110041836 | SOLAR CONCENTRATOR - The invention relates to a novel design for a solar concentrator formed by: a first upper bushing, a second upper bushing, a third upper bushing, a fourth upper bushing, a fifth upper bushing, a sixth upper bushing, a first lower bushing, a second lower bushing, a third lower bushing, a first upper bar, a second upper bar, a third upper bar, a first lower bar, a second lower bar, a third lower bar, a first vertical bar, a second vertical bar, a third vertical bar, a first diagonal bar, a second diagonal bar, a third diagonal bar, a first mirror, a second mirror, a third mirror and a fourth mirror. The solar concentrator is formed by small flat mirrors which can be adjusted using nuts in order to obtain the desired parabolic curvature, thereby providing a higher concentration coefficient. | 02-24-2011 |
| 20110100358 | Low Cost Fixed Focal Point Parabolic Trough - In accordance with one embodiment, a parabolic trough system is disclosed to capture solar heat. It has low mass, high rigidity and precise robust rotational control. The trough does not require massive supports, since it use a “sandwich structure” where the core is lightweight urethane foam and the skin is made of aluminum sheet. The inside skin also functions as the parabolic reflector. The shape minimizes wind loads by centering the receiver in the parabola and by making the center of focus the center of rotation. | 05-05-2011 |
| 20120060831 | PARABOLIC SOLAR COLLECTOR - A passive solar collector utilizes a support constructed of precisely machined foam to simplify the construction and calibration of the reflective surface. Further improvements include sensor-based positioning, and a receiver having inflow and outflow conduits adapted to improve thermal efficiency. | 03-15-2012 |
| 20120204862 | LOW COST PARABOLIC SOLAR CONCENTRATOR AND METHOD TO DEVELOP THE SAME - The present invention relates to a low cost parabolic solar concentrator and method to develop the same. The parabolic solar concentrator can be formed by deforming a hybrid plate. Force can be placed on an edge portion of the hybrid plate and/or a middle portion of the hybrid plate. The selective application of the force deforms the hybrid plate into a parabolic solar concentrator, instead of a sinusoidal shape. The hybrid plate can be formed from a first plate, a second plate, and a third plate attached to each other. The characteristics of the first plate, the second plate, and the third plate, can be chosen to allow the hybrid plate to be deformed into the parabolic shape with the selective application of forces. | 08-16-2012 |
