Abstract

Installation for the recovery of solar energy comprising numerous heliographs placed on the ground reflecting the sun's radiation and concentrating it towards a focal point in a furnace situated on a tower. The installation includes two control systems, the first being an arrangement allowing the automatic pursuit of the sun in its apparent movement across the sky. The second system comprises an electronic programmer which controls the movement of the heliographs when absence of sunlight prevents the automatic pursuit system from working. Each heliograph has a principal moveable mirror and a second small mirror fixed solidly to the main mirror. The second mirror reflects radiation to a secondary focus, this beam operating the mechanism which keeps the relative position of the principal mirror to the sun constant. The beam from this secondary mirror is received by four diametrically opposed lenses of television cameras placed at the periphery of the light spot. When the beam moves so that one or more of the lenses is outside the light spot the correcting mechanism operates. The use of a secondary smaller beam to operate the control mechanism makes the use of optical receivers possible. An automatic pursuit system operating alone necessitates large corrections after periods of cloud and after the darkness of the night. This can result in a time lag during which sunlight is wasted.
