Abstract: Briefly stated, floating rings which rotate around their vertical axis with predetermined relation to the azimuthal velocity of the sun are prevented from getting out of range by maintaining a desired spatial orientation between at least three fixed rollers circumferentially positioned. The present disclosure keeps floating rings together by encircling them.

Abstract: This invention relates to a system for producing solar power, comprising a rotating, circular platform that produces solar power and rotates about a vertical axis. Said platform (5, 6, 7) is provided with a plurality of floating troughs (9, 90, 91) with photoelectric cells (187, 199) which are covered by concentrating lenses (92, 182, 192). The platform (5, 6, 7) is surrounded by a circular, floating ring (10, 36) which is held in place by a device that grips only one area of the circumference of said floating ring (10, 36).

Abstract: The present invention relates to a solar power generator having special solar radiation concentrators configured as hollow bodies, and to such concentrators themselves. The invention relates in particular to a solar power generator having modules, arranged on a water layer, that contain a radiation converter, such that a plurality of modules is respectively combined into floating hollow bodies that comprise a wall that is subdivided into light-transmitting and non-light-transmitting regions.

Abstract: The invention describes large solar power plants, which consist of groups of rotating platforms. Three of said platforms comprising a triad having an interstitial pillar, said pillar has means to transmit torque to rotate the platforms and means to maintain the position of the platforms.

Abstract: Disclosed is a floating altazimuth-tracking array of point-focus lenses that concentrate direct sunlight on the upper ends of optical-homogenizer rods bonded to high-efficiency multi-junction photovoltaic cells. The cells are on heat sinks in altitude-tracking linear troughs holding multiple lens-rod-cell assemblies. Swiveling on horizontal axes, the troughs have their heat sinks always submerged in the water of a circular pond. Only knee-high al-together, the troughs and their floating frame rotate in the shallow pond for azimuth tracking. Closely packed floating platforms comprise solar electric farms with maximal land utilization.

Abstract: In a device designed as a rotatably mounted platform (a) for recovering solar electricity, the focusing roof layer (3) further deflects the incident radiation so that the light beams (122, 123, 126) formed by the concentrating optical system are incident approximately perpendicularly on the radiation converter (112) arranged underneath.

Abstract: The invention relates to a platform of the utilization of solar power which makes use of linear concentrators to beam the solar radiation for use in thermal, chemical or photovoltaic solar power converters, in which the azimuthal movement of the sun is followed by rotation about the main axis. The aim of the invention is to ensure an approximately uniform conversion rate of the solar radiation largely independently of the height of the sun while avoiding the use of a twin-axis follower system. The area available for utilizing the solar power is to be used as fully as possible as the aperture area to capture the radiation. According to the invention, a floating pipe (2, 2', 112) forming a torus is fitted as a frame for a horizontally extending planar bearer (3-4) held, by substantially evenly distributed buoyant bodies (13, 36, 46, 64a, 64b, 80b) borne by a liquid, at a vertical distance from solar power converting devices (33, 53, 73, 73', 93, 94b).

Abstract: Solar power plant consisting of elongated modules whose longitudinal axes lie in a plane parallel to the direction of the sun rays to be converted. These modules are covered by lenses which refract sun rays impinging under an oblique angle downwards and which comprise two groups of refracting portions mirror-symmetrically arranged along the zenithal line which portions converge the refracted, downwardly directed sun beams into wedges of rays. These wedges of rays run twice per day in a vertical plane and during the remaining sunshine hours move within a narrow angular interval either towards the sun or away from the sun. This angular motion results in a vertical movement of the focal line so that the focal line coincides only twice per day with the height of the strip type photovoltaic cells. To force all wedges of rays to impinge evenly distributed onto the photovoltaic cell, a secondary lens is arranged above the photovoltaic cells.

Abstract: A fluid flow machine consisting of a stator, mounted underneath a hot water tank, and an armature-impeller unit arranged inside said hot water tank, being separated from said stator by a spherical, magnetically permeable separation wall, which generates a toroidal vortex inside the water tank. Said vortex conveys hot water from the upper region of the tank to its lower region until the whole tank is filled with water of a uniform temperature.

Abstract: Latent heat storage means having, fusible at a pre-determined temperature, a mass which is traversed by heat exchanger surfaces and which fills a container jointly with the heat exchanger, characterized in that the container is constructed as a cylindrical vessel while the heat exchangers are formed from elongated strips wound spirally about a vertical axis.
