ABSTRACT:
An apparatus is provided for trapping solar energy emitted from the sun for heating a fluid that could be subsequently used in turbines and the like. The apparatus includes an elongated vertical light pipe having an open end through which the visible spectrum of electromagnetic radiation from the sun passes to strike a tubular absorber carried adjacent the other end thereof. The light pipe has a coated interior surface of a low absorptivity and a high reflectivity at the visible wave lengths and a high absorptivity/emissivity ratio at infrared wave lengths. The tubular absorber has a coating on the surface thereof for absorbing visible wave lengths so as to heat the fluid passing therethrough. Infrared wave lengths are radiated from the tubular absorber back into the light pipe for heating fluid passing through a tubular coil wound thereon.
