Abstract: A solar concentrating system for concentrating sunlight by tracking the sun, including concentrator support structure, an annular track mounted on an upper surface of a base, the center of mass of the concentrator support structure being off-axis relative to curvature center of annular track, enclosures provided at comers and comprising a wheel positioned on the track, the enclosure connected to a piston connected to a guiding element placed on the track; a fastening element that when moved towards the track, the guiding element is fastened to the track, and when the fastening element is moved away from the track, the guiding element is released, when the first piston elongates or contracts, the first guiding element is fastened to the track, the second guiding element is released, the wheels of the enclosures rotate from a first location on the track to a second location, thereby rotating the concentrator support structure.

Abstract: A plural axis sun tracking system, including a base, a spatial structure assembly, and a rotating system mounted on the base for rotating the spatial structure assembly, where the spatial structure assembly includes a frame having a lower portion at a first peripheral end of the spatial structure assembly and an upper portion at a second peripheral end of the spatial structure assembly, the lower portion being more proximal to the rotating system than the upper portion, and an anchoring location for anchoring the spatial structure assembly to the rotating system, the anchoring location located at the lower portion, where the mass of the frame increasingly recedes as the distance from the anchoring location towards the upper portion increases.
