摘要： The system captures and concentrates sunlight for transmission to interior spaces or to a PV system. A solar collector uses arrayed refractive lenses and opposing concave focusing mirrors and a movable coupling sheet forming part of a lightguide. The transparent sheet contains small angled mirrors, where each angled mirror corresponds to a particular set of the lenses/focusing mirrors and is in the focal plane. The lightguide also includes a fluid surrounding the transparent sheet, and lower index cladding layers sandwich the fluid. The sheet is translated within the fluid by an actuator to position the angled mirrors at the focal points of the sunlight for maximum deflection of the sunlight to an edge of the lightguide for extraction to a light transmission system or to a PV system. A position sensor on the sheet provides feedback regarding the position of the angled mirrors relative to the focal points.

The silica aerogel may have greater than 95% solar-weighted transmittance at a thickness of 8 mm for wavelengths in the range of 250 nm to 2500 nm, and a 400° C. black-body weighted specific extinction coefficient of greater than 8 m2/kg for wavelengths of 1.5 μm to 15 μm. Silica aerogel synthesis methods are described. A solar thermal aerogel receiver (STAR) may include an opaque frame defining an opening, an aerogel layer disposed in the opaque frame, with at least a portion of the aerogel layer being proximate the opening, and a heat transfer fluid pipe in thermal contact with and proximate the aerogel layer.

摘要： The present invention offers an improvement to existing canting, slope error, and/or pointing measurement approaches, by using one or more cameras to observe the reflections of points of light in the firmament, such as the reflections of stars and/or planets as visible within the night sky in the heliostat facets. An illustrative heliostat measurement system comprises a plurality of heliostats, and at least one camera that observes at least one heliostat. The heliostats reflect an image of the firmament that can be observed by the at least one camera. The system further comprises (i) at least one captured image of the firmament reflected from at least one of the heliostats; and (ii) a computer comprising programming that determines a heliostat imperfection from the captured image, wherein the heliostat imperfection is selected from at least one of a slope error, a canting error, and a pointing error.

摘要： A heat concentrator device for a solar power system includes an evacuated hollow body with a bottom, side walls, a top and an airtight cap. Portions of the side walls have inwardly reflective surfaces for concentrating solar radiation into the chamber toward a heat sink, which is positioned in the bottom of the chamber. The heat sink also is hollow and has an inlet port formed in one of its opposite side walls and an outlet port formed in the other for heat transfer fluid to flow into and out of the heat sink. Circuitous passageways form a maze that connects the inlet and outlet ports thus maximizing heat transfer to/from system fluid(s) within the heat sink. The sidewalls of the chamber of the device extend below the heat sink to form a partial vacuum chamber between its bottom and the heat sink. The device is mounted to a reflective dish of a solar power system in a unique way adding additional solar energy collection efficiencies.

摘要： The parabolic trough collector has a receiver formed by several single absorber tubes (13). The single absorber tubes (13) are supported by absorber tube supports (14) and surrounded by a glass tube (15). Because of different expansion behavior of the absorber tube (13) and the glass tube (15) during collector operation flexible unions (17) are foreseen between absorber tube (13) and glass tube (15). In order to use the radiation coming to the non active-area where the absorber tube supports (14) and the flexible unions (17) are installed a mirror collar (20) is installed on this area. The mirror collar (20) is able to reflect the solar radiation, which is coming from different directions, to the active absorber part of the single absorber tubes (13) also when the sun incident angle is changing.

摘要： A light refracting and collecting assembly includes a housing having a bottom surface with two diverging side walls extending therefrom, two opposing end walls and an open top. Disposed between the side walls, proximal the bottom surface, is a light absorbing means such as a heat conductive conduit or a photovoltaic cell collector plate. Angularly extending from the upper surface of the light absorbing means are a plurality of substantially triangular prisms for refracting and directing light from the open top of the housing downwardly towards the light absorbing means. The interior surface of the side walls and bottom surface are coated with a light reflecting material to further direct light toward the light refracting prisms and the light absorbing means. A transparent cover member is superimposed on the open top for protecting the interior and to bend light towards the light absorbing means. The device is designed to increase the intensity of light contacting the collector plates to minimize the size of conventional collector plates and whereby the duration of usable sunlight is extended.

摘要： A solar insolation concentrator fabricated from a rigid lightweight (slab-like substrate and a plurality of reflectors. Inclined surfaces are formed in the face surface of the substrate, such as by impressing a heated plate portion of a fabrication tool into the substrate material. The fabrication tool is then used to position the reflectors as they are adhered to the inclined surfaces to assure that the reflectors are aligned with respect to a common focal point. An embodiment of the solar insolation concentrator comprising a plurality of identical square flat back-silvered glass mirrors mounted within recesses within a block of high density cellular polystyrene and a tool and process used to fabricate this concentrator are disclosed. The solar insolation concentrator is also suited for use as a reflector of electromagnetic radiation having wavelengths outside the solar energy spectrum.
