Abstract:
The method is for conveying solar power from a sun. A solar concentrator (102) conveys and concentrates solar power as rays (107) into a glass rod (104). The solar concentrator (102) has a tapering device (200) disposed at a bottom (112) thereof. The glass rod (104) has a first curved glass loop section (108a), a second curved glass loop section (108b) and a straight glass section (130). The straight glass section (130) has an outer end (602) that is positioned in proximity to a water surface (600) to heat water (598). The first loop section (108a) is rotated relative to the second loop section (108b) at a first gap (118) and the second section is rotated relative to the straight section (130) at a second gap (126) so that the concentrator (102) can follow the path of the sun during the day.

Abstract:
La presente invención consiste en un Concentrador Solar de Potencia (CSP), formado por una serie de largos espejos planos (tipo Fresnel) orientados en dirección Norte-Sur, cada uno con un solo eje Este-Oeste de rotación con seguimiento de la altitud del sol, que conjuntamente reflejan la luz a lo largo del día a un solo espejo cilindro- parabólico, concentrando este la radiación solar a una pequeña zona cercana a la linea focal de la parábola en la que se encuentra un absorbedor que calienta fluidos y/o genera electricidad.
Abstract:
Apparatus to collect solar radiation using a series of lenses or mirrors that concentrate the solar energy onto targets. A gaseous working fluid flowing through the targets is heated and optionally supplied to a heat store having an internal walled labyrinth of a suitable material to store heat energy. A heat exchanger, turbine and electricity generator are coupled to the collection and storage apparatus so as to provide a power plant for the conversion of solar energy to electricity.
Abstract:
A device for gaining solar energy comprises a integral unit with a casing (10..13). The casing comprises reflection means (20) with a hollow reflector surface (25) and is closed off by refraction means (30) with an entry surface (35) for entering sunlight. The refraction means and reflection means are each rotatably arranged around a rotation axis (71, 72) and their orientation relative to each other is continuously adjusted to the current position of the sun in the sky using positioning means provided for that purpose. The casing comprises a number of dustproof, but nevertheless ventilating chambers. The first chamber (100) is situated between the refraction means (30) and the reflection means (20) and comprises energy-conversion means (40) at least near to the focal point of the reflector surface (25). A second chamber (200) is situated between the reflection means (20) and the base part (13) of the casing and comprises positioning means (51, 53) for rotating the refraction means (30) and the reflection means (20).
