ABSTRACT:
A solar energy conversion apparatus which includes a reflective parabolic trough which tracks the sun the control means therefor being such that the trough rotates about a north-south axis alternately to east and west extreme positions until the driving motor is disabled by equal irradiation of a pair of phototransistors. The phototransistors are aligned relative to the axis of the trough such that they are equally irriadated when the sun's rays are concentrated on a heat transfer tube extending along the axis of the trough. The apparatus has a flexible disc drive member to mechanically couple the trough to the drive motor. The heat transfer conduit is of relatively small capacity and a two-phase flow therein is utilized so as to conserve energy.
