Large area parabolic concentrating solar collector

Patent ·
OSTI ID:5979903
An apparatus is disclosed for the concentration of solar radiation by directing it upon Fresnel zone sections of axially short, electroplated surfaces of spin cast parabolic mirrors. The short focal length optical system is composed of off axis parabolic surfaces of revolution and secondary reflectors. These reflectors concentrate the suns rays to produce heat with which to generate steam, and to melt high temperature salts.
