Abstract
Abstract A solar energy absorber is provided in which the absorber surface is comprised of a multiplicity of free ends of carbon or metallic fibers. The fibers forming the absorber surface are straight and are aligned in a parallel and side-by-side relationship. The small diameters of the fibers and the very close spacing of adjacent fibers of from 1 to about 10 micrometers provides a trap for solar energy. A solar energy absorbing device is also provided.
