Solar electric power generator

摘要

A solar concentrator includes a first reflective surface formed parabolic along a first axis and a second reflective surface formed parabolic along a second axis which is perpendicular to the first axis. The focal length of the second reflective surface is shorter than the focal length of the first reflective surface for crossing focal lines of the first and the second reflective surfaces at a point. A method of concentrating solar light includes reflecting the light off a first reflective surface having a single parabolic axis to generate a first reflected line, and reflecting the first reflected line off a second reflective surface having a single parabolic axis. The parabolic axis of the first reflective surface is oriented perpendicular to the parabolic axis of the second reflective surface to focus the light to a point.
