APPARATUS FOR CONVERTING SOLAR ENERGY TO MECHANICAL ENERGY (VARIANTS) Russian patent published in 2004 - IPC

FIELD: solar energy using systems, possibly in different industry branches.

SUBSTANCE: according to first variant apparatus includes three rectangular planes inclined by 90 degrees one relative to another. Metallic black vessel is arranged in horizontal plane for heating water and generating steam. Laminate transparent heat insulation material is arranged over said vessel. The last may be connected to steam-driven motor through flexible hose. According to second variant apparatus includes four reflectors inclined one relative to another for forming fluid-tight cavity inside which glass for inlet sun beams are placed. Apparatus operates according to isochoric process. Piston in the form of bellows is connected with said cavity and it may be connected to wheel. Apparatus according to third variant is similar to apparatus of second variant, but it is made of light material and it has non-sealed cavity. Such apparatus operates at constant pressure when temperature raises.

EFFECT: possibility for carrying out mechanical work with use of solar energy.
