  • Patent number: 10032947
    Abstract: A light concentrator includes a luminescent concentrator and a gain medium. The luminescent concentrator includes a semiconductor material and the semiconductor material absorbs first photons. The first photons have energy greater than or equal to a threshold energy, and the semiconductor material emits second photons through a spontaneous emission process where the second photons have less energy than the first photons. The gain medium is optically coupled to the luminescent concentrator to receive the second photons. The gain medium absorbs the second photons, and in response to absorbing the second photons, the gain medium emits third photons through a stimulated emission process. The third photons have less energy than the second photons.

  • Patent number: 10024577
    Abstract: Common solar radiation receivers are equipped with a chamber for transmission of an operating gas which is directed along to an absorber for solar radiation for thermal absorption. The absorber has a dome-shaped entry window made of quartz glass, wherein the inner side facing the absorber assumes a nominal interior temperature Ti of at least 950° C. during proper use, preferably at least 1000° C., whereas the outer side facing away from the absorber is exposed to the environment and subject to risk of devitrification. The invention relates to modifying the known solar radiation receiver so that a high absorber temperature can be set and thus a high efficiency of the solar thermal heating is enabled, without increasing the risk of devitrification in the region of the outer side of the entry window.

  • Patent number: 9006560
    Abstract: A lightweight reflector with a load bearing structure based on a tensile spoke-wheel. The spoke structure is especially compatible with dish parabolic mirrors, but has utility as a carrier structure for any round functional surface, including flat or slightly-curved mirrors used in central tower solar systems, parabolic dishes for radio telescopes and antennas, and for non-concentrating thin film solar panels. There are no radial members loaded in compression. All the spokes pull the rim inwards, and the rim is compressed in the circumferential direction. The imbalance in spoke tension results from the application of load provides the rigidity of the rim in respect to the hub, both for in-plane and out-of-plane forces. Ribs stiffen the spokes to resist wind and gravity, but are not structurally supported by either the hub or the rim. Lightweight reflector tiles match the wheel structure and create the reflective surface.

    Abstract: A solar collector is formed as a compound arrangement of a multiple number of tapered, pyramidal-type structures. This forms an N-stage solar collector, each stage providing a degree of concentration and thus forming an arrangement that is smaller than a single stage collector (while achieving the same amplification factor). The stages are arranged in tandem along a common optical axis, with the output of the first stage becoming the input for the second stage, and so on. It was found that a reduced number of reflections is required, reducing the loss of the overall system.

  • Patent number: 8931475
    Abstract: Systems and methods for directly monitoring energy flux of a solar receiver in a solar energy-based power generation system include measuring infrared radiation emanating from the solar receiver. Such measurement can be achieved using one or more infrared thermography detectors, such as an IR camera. Resulting thermal data obtained by the imaging can be used to determine energy flux distribution on the receiver. A user or a system controller can use the determined flux distribution to adjust heliostat aiming to achieve a desired operation condition. For example, heliostats can be adjusted to achieve a uniform energy flux distribution across the external surface of the receiver and/or to maximize heat transfer to a fluid flowing through the receiver within system operating limits.

    Abstract: At least some of the heliostats can be arranged and operated in such a manner that the maintenance vehicle can pass through the solar field along conditional pathways. The arrangement and control of the heliostats to allow access to heliostats by a maintenance vehicle can enable different heliostat patterns as compared with conventional arrangements. In particular, heliostats in one section of the solar field, which may be less geometrically efficient, can be arranged at a higher density as compared to heliostat in another section of the solar field. In addition, the locations of heliostats in various sections of the field can be optimized based on ground coverage as viewed from a vantage point in the solar tower and/or revenue generation without constraining the locations to particular line or arc patterns.

  • Patent number: 8360052
    Abstract: Melting metals using the sun's energy is not new, but is new is making the technology ergonomic, and easy to use. Invented is a half-circular-planar-reflector with a cut-a-way-triangle, hinged and attached a half-shell-parabolic-reflector. When the sun is overhead, the sun's energy reflects off the flat half-circular-planar-reflector to a half-shell-parabolic-dish-reflector, which redirects the sun's energy to a crucible for smelting metals, which is also the focus of the sun's energy. 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 energy. A smaller version of the smelter can be used for solar cooking.

  • Patent number: 8360051
    Abstract: A solar energy collection system has a solar receiver with an external surface configured for high absorption of light incident thereon. The solar receiver also has a plurality of light-reflecting elements arranged on the external surface. The light-reflecting elements produce at least partially diffuse reflection of light energy incident thereon. Heliostats concentrate solar radiation onto the external surface of the solar receiver. An imaging device provides a digital image of at least a portion of the external surface of the solar receiver. A controller can control the heliostats in response to apparent brightness of the light-reflecting elements as represented in the digital image.

  • Patent number: 8333186
    Abstract: A parabolic trough solar collector system has a parabolic reflector used with an independently supported collector tube. The parabolic reflector has a reflective surface formed on a reflective surface support structure, supported by a circular support beam. This assembly rests on a plurality of support and drive rollers supported by a roller support arm, supported by a roller support column. The parabolic reflector assembly rotates against the rollers along a single axis to maintain a focus line of the parabolic reflector surface at the same location as the center of the circle described by the outer edge of the circular support beam. Located at this same focus line is the independently supported collector tube not attached to the parabolic trough reflector. The collector tube is supported on pipe roller hangers, which in turn are supported by a wire catenary system connected to support towers which straddle the parabolic reflector.
