Abstract:
An optical system having an optical waveguide for collecting light, a receiver for receiving the light, and redirecting optics for transferring the light from the optical waveguide to the receiver. The optical system can be used for concentrating light such as in solar applications. The optical system can also be used for diffusing light in illumination applications by replacing the receiver with a light source such that the light flows in the reverse of the concentration system.
Abstract:
The present invention relates to apparatus and methods to provide a control system for the purpose of redirecting light from a source onto a target. The present invention appreciates that the optical properties of light that is both modified and/or distributed, e.g. by diffraction, diffusion, or some other process, and also redirected by a heliostat, can be a function of how the light redirecting element is aimed. This means that the aim of the light redirecting element can be precisely determined once the aim of the modified and/or distributed light is known. Advantageously, the characteristics of modified and/or distributed light indicative of how that light is aimed can be determined from locations outside the zone of concentrated illumination in which sensors are at undue risk. This, in turn, means that modified and/or distributed light characteristics can be detected at a safe location, and this information can then be used to help precisely aim the light redirecting element onto the desired target, such as a receiver in a CSP system. The aim of the modified and/or distributed light is thus an accurate proxy for the light beam to be aimed at the receiver.
Abstract:
An optical concentrator having a concentrating element for collecting input light, a redirecting element for receiving the light and also for redirecting the light, and a waveguide including a plurality of incremental portions enabling collection and concentration of the light onto a receiver. Other systems replace the receiver by a light source so the optics can provide illumination.

Abstract:
A passive electromagnetic radiation collector is presented for use with a radiation converter. The radiation collector comprises at least one basic block. The basic block of the collector is substantially transparent to the electromagnetic radiation and has spaced-apart first and second surfaces, by which the basic block when in operation is exposed to a source of the electromagnetic radiation and faces the radiation converter respectively. The first surface of the basic block has a dome-shaped configuration of a predetermined curvature. The second surface of the basic block is formed by refractive interfaces defining an apex structure aligned with an uppermost region of the dome, and sloping downward toward edges of the block, such that the refractive interface directs at least a part of radiation collected by the first surface onto a region outside the basic block on a plane spaced apart from the second surface, thereby enabling interaction of the at least part of the collected radiation with a corresponding region of a radiation sensitive surface of the radiation converter located in the plane.
Abstract:
The present invention relates to an environmentally friendly, multipurpose light-collecting and duct apparatus using sunlight, which is in particular installed in predetermined above-ground and below-ground locations in various buildings, to separate collected sunlight into ultraviolet rays, infrared rays, and visible rays and supply the separated light for use in desired areas within the building, thereby achieving environmental friendliness and luxuriousness for the building as well as minimizing energy consumption. For this purpose, the environmentally friendly, multipurpose light-collecting and duct apparatus using sunlight according to the present invention comprises: a modularized light-collecting lens plate erected at a desired location of a building to collect sunlight; a sunlight-diffusing lens plate disposed above and spaced apart from the modularized light-collecting lens plate, for diffusing sunlight toward the modularized light-collecting lens plate; a plurality of reflective lenses disposed below and spaced apart from the light-collecting lenses of the modularized light-collecting lens plate, respectively, to reflect sunlight; a multi-surface reflective base disposed below and spaced apart from the center of the modularized light-collecting lens plate to vertically reflect the sunlight reflected from each reflective lens back in a single direction; a light-separating device disposed above or below the multi-surface reflective base, for filtering the sunlight reflected from the multi-surface reflective base into ultraviolet rays, infrared rays, and visible rays, respectively; and an air-cleaning device for receiving infrared rays separated by the light-separating device through an infrared light pipe, and filtering external air.
Abstract:
The sun collector (15) according to the invention has a novel unit for focusing and transmitting light (9). It comprises at least one transparent sphere (1), which generates a focal point (5) onto a spherical surface outside of the sphere (1) as a function of the position of the sun. A mechanical device (2, 3, 4, 8) following the focal point (5) fixes the same in any position predetermined by the sun. Due to the matrix-shaped arrangement of a plurality of transparent spheres (1) having a small diameter, a flat sun collector (15) is formed, which corresponds to the conventional integrable installation size of commercially available hot water collectors. The same may therefore be permanently installed in roof or cladding elements and has no interfering mechanical elements on the outside. Despite the position of the sun constantly changing, the collector is able to focus the direct sunlight and utilize the same in a focused manner. When supplying sun energy to a light conductor, said energy may be conducted to any arbitrary location where the focused light fulfills various tasks by means of a light conductor switch.
Abstract:
A system and method for increasing the efficiency of an ocean thermal energy conversion (OTEC) system is described. In some examples, the system collects thermal energy using a solar collector, warms ocean water located within the solar collector, and provides the warmed water to an OTEC system, such as to a vaporizer of a heat engine. In some examples, the OTEC system provides electricity and other energy to another system, creating a cycle of sustainable economic development of energy and resources.
Abstract:
The present disclosure is directed to a system and method of providing energy to a dwelling. An engine is housed within an inner tank, which is in turn housed within an outer tank. The engine provides electricity which is used for a dwelling. Exhaust fumes from the engine are piped through a series of heat- exchanging tubes within the outer tank to heat potable water within the outer tank. Water enters the potable tank at a bottom of the tank, and warms as it rises through the outer tank toward an outlet near a top of the outer tank. Hot, potable water is provided from the top of the outer tank to the dwelling. Condensate from the exhaust is captured and used as potable water. Heat, vibration, and acoustic energy from the engine is captured by the fluid in the inner tank and transferred to the outer tank.
