Patent number: 7960641Abstract: This invention deals with novel method and apparatus for positioning and motion control of the elements (lenses) of a Fresnel lens solar concentrator tracking array by induced and/or permanent dipole coupling to an electronic grid to produce angular deflection, and rotational motion. Thus forces and torques are produced without the use of internal moving parts. Control can be achieved without recourse to magnetic fields, by means of high electric fields which may be attained at relatively low voltages. At low voltages, the instant invention exceeds the capability of conventional systems. It can perform dynamic motion control with independent amplitude and frequency modulation. It is ideally suited for maximization of solar energy focused by the array onto a receiver. Since there are no mechanical likages, the instant invention is the most adapted for fabrication from the mini- to the micro-technology realm. Furthermore it provides less costly and greater ease of manufacture from the mini-to the micro-realm.Type: GrantFiled: January 30, 2008Date of Patent: June 14, 2011Inventor: Mario Rabinowitz

Luminescence Concentrators and Luminescence Dispersers on the Basis of Oriented Dye Zeolite Antennas
Publication number: 20110094566Abstract: A luminescence concentrator (LK) may concentrate both incident direct and diffuse light by way of frequency shift and total internal reflection. It differs fundamentally from geometric concentrators. With sufficient geometric expansion of the collector plate, nearly arbitrarily high concentration can be achieved in the LK. A luminescence disperser is an apparatus which holds both directional and nondirectional incident light captive in a transparent body by way of frequency shift and total internal reflection and emits it diffusely or directionally uniformly distributed across an area by way of luminescence emission. The object of the invention is a method for the technical implementation of the LK and luminescence disperser, using zeolite crystals having a nanotube structure, into which the luminescent dyes are embedded such that they have antenna properties. Using the resulting novel structures, problems can be solved which made the technical use of LK impossible or at least considerably limited it.Type: ApplicationFiled: March 31, 2009Publication date: April 28, 2011Applicants: UNIVERSITÄT ZÜRICHInventors: Gion Calzaferri, Andreas Kunzmann, Dominik Brühwiler, Christophe Bauer -

Publication number: 20100192944Abstract: A water heating/distillation chamber with multiple lenses arranged on its external walls such that direct sunlight from any direction is input into the chamber to heat the chamber contents. An input line provides water when necessary, and an output condensing structure channels water vapor out of the device for condensation into distilled water. Alternatively, a supply of hot water can be output from the chamber after heating. Alternatively, steam can be generated which can be used as an energy source for turbines. The chamber can be fabricated from glass, or any other material suitable for creating a greenhouse effect inside the chamber. The device can be applied to a wide spectrum of uses, from large scale commercial activity to small applications such as camping equipment.Type: ApplicationFiled: February 5, 2009Publication date: August 5, 2010Inventor: Max L.

Patent number: 7694673Abstract: This invention absorbs available heat from the flue gas of an existing building's heating system and heat from the sun. The heat is absorbed and stored in a heat-collecting sphere of special design. The absorbed heat collected in the sphere is transferred, by the conventional refrigeration cycle, to the heat exchanger located at the air inlet to the building heating system. The refrigerant liquid is sprayed into the collecting sphere, as it absorbs heat, it evaporates and changes into a gas. The refrigerant compressor transfers the gas from the heat-collector to the heat exchanger. The existing heater fan draws air across the heat exchanger finned coil removing heat from the refrigerant. The refrigerant gas gives up heat and is condensed. The heated air combines with the existing furnace air to heat the existing building. The refrigerant liquid from the heat exchanger is transferred to the heat-collecting sphere spray nozzles.Type: GrantFiled: December 4, 2006Date of Patent: April 13, 2010Inventor: Joseph Francis Brown, Jr.

Publication number: 20100024801Abstract: A collector includes a convergent lens (2) having a focal distance f and an image focal plane (PFI). The convergent lens (2) defines one of the walls of a casing (1) defined by two pairs of side walls (4a, 4c), a bottom wall (3) and a front wall defined by the lens (2), the side and bottom walls on the inside of the casing being reflective, and the depth p of the casing being lower than the focal distance f of the lens so that after multiple reflections, the ray beam (R1, R2) thus reflected is concentrated on a final image focus (I?) located inside the casing, the collector including a mobile receptor (6a) held inside the concentrated beam or in a position at least intersecting the beam by elements controlling the movement of the collector (6a) with that of the beam.Type: ApplicationFiled: March 3, 2008Publication date: February 4, 2010Applicant: Commissariat A L'Energie AtomiqueInventor: Qinglong Lin

Patent number: 7642450Abstract: A solar collector arrangement includes a number of assemblies (1), which are immersed or partially immersed in a pond of water (2). Each assembly (1) includes a parabolic reflector (3) and an absorber (6). Barriers (10) are located on or near the surface of the water (2) and operate to reduce waves which may otherwise disturb the direct passage of sunlight in windy conditions. The complete immersion of the assembly (1) in the liquid serves to simultaneously protect and cool the apparatus, while allowing ease of sun 10 tracking movements by buoyancy induced rotation. Partially immersed versions have higher efficiency and protect against severe weather by inverting into the water.Type: GrantFiled: May 27, 2004Date of Patent: January 5, 2010Assignee: Sunengy Pty LimitedInventor: Philip Michael Connor
