AN APPARATUS FOR SOLAR TRACKING USING MINIMAL ENERGY IS DESCRIBED. A PRISMATIC ENERGY HARVESTER (10) IS POSITIONED ABOVE A SPRING (20). THE HARVESTER HAS A PAIR OF EARS (14) AT BOTH SIDE OF THE TOP PORTION OF THE HARVESTER. THE EAR IS MOVED BY STRINGS (16) FROM A REEL (18) CONNECTED TO A BOX OF MOTOR (12). AT LEAST TWO PHOTO-RESISTIVE ELEMENTS TRACK THE SUN RAYS INTENSITY TO IDENTIFY THE POSITION OF THE SUN. THEN, THE MOTOR ADJUST THE REELS TO ROTATE THE HARVESTER USING STRINGS UNTIL THE HARVESTER AND THE SUN IS AT RIGHT ANGLE. THE PHOTO-RESISTIVE ELEMENTS CONTINUOUSLY TRACK THE SUN SO THAT THE HARVESTER CAN BE ROTATED TOWARDS THE SUN AT RIGHT ANGLE. |
