Abstract
Technical challenges of efficiently and cost-effectively deriving energy from the sun are addressed using a manifold and an array of evacuated tubes in fluid connection, in a butterfly or other planar arrangement. Tube and manifold fluid guides are plumbed for coaxial flow and/or parallel flow, and thermally protected by sleeves, stainless steel piping, and/or vacuum. Tubes are provided with a selective low emissivity coating and/or internal mirror to reduce thermal loss. The solar absorption surface of evacuated tubes may be five square meters or more, with only low-quality concentration optics, or no concentration optics used. The tubes array tracks the sun with a two-axis motion platform. Fluid operating temperatures range from 150 to 300 degrees centigrade, depending on the sunlight exposure, working fluid, and supplemental heat source if any. Fluid may circulate heat between the manifold and heat engine, cogeneration facility, and/or other module.
