Abstract: A steam generator that reduces the thermal and hydraulic unevenness in the steam generator, improves the filling capacity of the steam generator with heat exchange tubes, organizes an economizer portion of the heat exchange surface in the steam generator, and reduces the concentration of corrosive impurities in the weld zone of the primary circuit to the horizontal shell. To solve the task in such steam generator containing the horizontal shell and other component, the heat exchange tubes are located in vertical planes, and the inlet and outlet manifolds of the primary circuit are arranged horizontally. The steam generator can also be equipped with at least two output manifolds of the primary circuit furthers, the feed water dispenser can be located below the heat exchange tubes of the steam generator.

Abstract: The described embodiments provide thermal energy via solar powered heat exchangers. This energy can be implemented to heat hot water or heat residential/commercial structures. Parallel mounted vacuum insulated tubes heat water within a geometric heat transfer piping system. This thermal energy is transferred via a piping system to an insulated tank. A digital controller monitors and controls the temperature of the water within the system as well as provides frost/freezing protection. An electrical active pumping system is connected to the digital controller to circulate water within the solar heat exchanger. The electric active pump can be connected to a solar photovoltaic (electric) panel for reliable and uninterrupted heat/hot water delivery.

Abstract: According to an embodiment of the present invention, there is provided an aspherical mirror for focusing a laser beam in a linear pattern, the aspherical mirror including: a convex surface diffusely reflecting an irradiated laser beam; and a concave surface reflecting the laser beam such that the laser beam is focused at one point, wherein the laser beam reflected from the convex surface forms a long line beam as an angle of reflection with respect to a curvature of the convex surface changes, and the laser beam reflected from the concave surface is focused at one point on the line beam as an angle of reflection with respect to a curvature of the concave surface changes.

Abstract: An arrangement utilizes diffractive, reflective and/or refractive optical elements combined to intensify and homogenize electromagnetic energy, such as natural sunlight in the terrestrial environment, for purposes such as irradiating a target area with concentrated homogenized energy. A heat activated safety mechanism is also described.

Abstract: There is disclosed herein a concentrating solar energy receiver comprising a primary parabolic reflector having a center and a high reflectivity surface on a concave side of the reflector and having a focal axis extending from the concave side of the reflector and passing through a focal point of the primary parabolic reflector; and a conversion module having a reception surface wherein the reception surface is spaced from the focal point by a predetermined distance and disposed to receive a predetermined cross section of radiant solar energy reflected from the concave side of the primary parabolic reflector for conversion to electrical energy in the conversion module. In one aspect, the conversion module includes a reception surface comprising a planar array of at least one photovoltaic solar cell. In another aspect, the conversion module includes a reception surface coupled to a thermal cycle engine. The mechanical output of the thermal cycle engine drives an electric generator.

Abstract: A solar energy collecting apparatus for heating a working fluid using the plurality of substantially identical reflective elements arranged in rows is provided. Each reflective element comprises a substantially rectangular element having opposing side walls and opposing end walls which together form a bottom edge for supporting the reflective element on a flat support such as a sheet metal or molded base. Each reflective element further includes a top wall connected with and supported by the side walls and the end walls. The top wall is formed to provide a reflective surface facing away from the bottom edge and is formed in a shape for reflecting solar radiation falling thereon, from a range of incident angles, to a focal axis. The focal axis of each reflective element is substantially parallel with a longitudinal axis of the reflective element and when the reflective elements are arranged in parallel rows, each row includes a focal axis along its longitudinal length.

Abstract: The present invention relates to an improved solar energy concentrating system incorporating replaceable solar energy concentrating reflectors. Prior systems typically required a structurally stable solar energy concentrating panel. The present invention uses a combination of structurally stable backing panels and flexible solar energy concentrating reflectors to significantly reduce the ease and cost of replacing reflectors.

Abstract: This invention involves a novel egg-shaped hollow dual-compound conical light-ray concentrator with mirror-like inner walls (preferably tandem substantially inverted paraboloidal and ellipsoidal conical sections) for receiving light through one aperture end, as from an integrating sphere, and concentrating and collecting the rays within said walls and directing them to a detector at an opposite aperture end. This construction attains both high collection efficiency and hemispherical angular response.
