Abstract:
In one embodiment a solar collector is provided. The collector has a modular heat transfer component, which includes a heat transfer core to heat up a heat transfer fluid in the form of an aerogel. The heat transfer core positioned comprises a light absorption element, and a fluid transfer element in the form of an aerogel. The aero gel comprises voids shaped and dimensioned to support passive pumping of the heat transfer fluid therethrough.
Abstract:
The disclosure is directed to a system for using focused light to heat a fluid to ultra-high temperatures a light concentrator and onto one or more substantially monocrystalline ceramic elements. The light concentrator is selectively positioned to direct concentrated light onto one or more substantially monocrystalline ceramic elements. Each of the one or more substantially monocrystalline ceramic elements include metal ions that are naturally capable of substantially absorbing said concentrated light in order to reach a desired ultra-high temperature.
Abstract:
A method is provided for using asymmetrically focused photovoltaic conversion in a hybrid parabolic trough solar power system. Light rays received in a plurality of transverse planes are concentrated towards a primary linear focus in an axial plane, orthogonal to the transverse planes. T band wavelengths of light are transmitted to the primary linear focus, while R band wavelengths of light are reflected towards a secondary linear focus in the axial plane. The light received at the primary linear focus is translated into thermal energy. The light received at the secondary linear focus is asymmetrically focused along a plurality of tertiary linear foci, orthogonal to the axial plane. The focused light in each tertiary linear focus is concentrated into a plurality of receiving areas and translated into electrical energy. Asymmetrical optical elements are used having an optical input interfaces elongated along rotatable axes, orthogonal to the axial plane.
Abstract:
Methods, systems, and devices are disclosed for fabricating and implementing optically absorbing coatings. In one aspect, an optically selective coating includes a substrate formed of a solar energy absorbing material, and a nanostructure material formed over the substrate as a coating capable of absorbing solar energy in a selected spectrum and reflecting the solar energy in another selected spectrum. A concentrating solar power (CSP) system includes heat transfer fluids (HTFs); thermal energy storage system (TES); and solar receivers in communication with HTFs and including a light absorbing coating layer based on cobalt oxide nanoparticles.
Abstract:
Recubrimientos absorbentes para receptores solares centrales yprocedimiento para la preparación in situde dichos recubrimientos mediante el empleo de un equipo portátil de proyección por plasma en el que se deposita una primera capa metálica de anclaje, preferiblemente de Ni20Cr, y una capa de material cerámico o cermet en unas condiciones tales que permiten obtener recubrimientos altamente absorbente en el rango solar, con muy buen comportamiento mecánico y alta durabilidad. El procedimiento también requiere unas etapas previas de secado del material a depositar y preparaciónsuperficial del sustrato (superficie del receptor). La presente invención también se refiere a los recubrimientos así formados.
