Abstract
Abstract A solar energy collector, including an assembly of reflectors supported pivotally upstanding upon a circular carriage that rotates once a day upon horizontal, circular tracks, the reflector assembly being adjustable in inclination, so as always to face the sun directly, by means of a brace against its upper end, and the brace lower end traveling in a cam-shaped track having raised and lowered portions, and an electronic programmer activated by the sun light, so as to turn on an electric motor that rotates the carriage.
