The present disclosure relates to a concentrator, particularly a terrestrial solar concentrator to harness the sun's energy, and a tracking system. The concentrator includes a parabolic or other curved reflective surface and an absorber positioned at the focus of the curved reflective surface. Parabolic ribs give shape to the reflective surface. The tracking system includes a rotating, swiveling, or pivoting joint. One or more cables attach to the tracking system. Selectively applying tension to the cables causes the tracking system to rotate, swivel, or pivot at the joint to track an object.

1. A tracking system, comprising: a platform configured to accommodate an object;at least one support leg attached to the platform, the at least one support leg having a pivoting anchor point situated away from said platform; andat least one flexible cable attached to the platform,wherein the at least one flexible cable passes through a fixed anchor point, wherein the platform is adapted to pivot at the pivoting anchor point in response to a tension applied to the at least one flexible cable, and wherein said pivoting anchor point allows tracking along separate axes. 2. The tracking system of claim 1, wherein the fixed anchor point is positioned away from the tracking system. 3. The tracking system of claim 1, wherein the at least one-flexible cable passes through at least two anchor points and secures to at least two sides of the platform. 4. The tracking system of claim 1, wherein the object is a solar collector, telescope, a camera, or a satellite dish. 5. The tracking system of claim 1, whereby the pivoting anchor point is positioned on the at least one support leg away from the platform. 6. The tracking system of claim 1, wherein the apparatus pivots around at least two axes of rotation. 7. The tracking system of claim 1, further including a solar concentrator mounted on the platform, wherein the solar concentrator comprises: a reflective surface having a curved shape and a focal point above the reflective surface,wherein the reflective surface comprises a flexible sheet of reflective material; a reinforcement sheet supporting the reflective material, wherein the reinforcement sheet is stiffer than the reflective material; a plurality of curved ribs attached to the reinforcement sheet; and an absorber located at the focal point. 8. The tracking system of claim 7, wherein the reflective material comprises aluminized Mylar adhesively attached to the reinforcement sheet. 9. The tracking system of claim 7, wherein the absorber comprises photovoltaic cells. 10. A method of collecting solar energy, comprising: assembling a portable solar concentrator at a first location, said portable solar concentrator having a tracking system as in claim 1;collecting concentrated solar energy at the first location using the portable solar concentrator;transporting the portable solar concentrator to a second location; andcollecting concentrated solar energy at the second location using the portable solar concentrator. 11. The tracking system of claim 1, wherein said separate axes are longitudinal and latitudinal axes. 12. A portable solar concentrator, comprising: a reflective surface having a curved shape and at least one focal point above the reflective surface, wherein the reflective surface comprises a flexible sheet of reflective material;a reinforcement sheet supporting the reflective material, wherein the reinforcement sheet is stiffer than the reflective material;a plurality of curved ribs attached to the reinforcement sheet;an absorber located at the at least one focal point; anda support stand hingedly connected to the curved ribs,wherein the curved ribs, reinforcement sheet, and reflective material may swivel relative to the support stand on a roughly horizontal axis;wherein the portable solar concentrator is adapted to track a target along separate axes by applied tension to cables attached to a platform of the portable solar concentrator, which cables pivot said platform about an anchor point situated away from said platform. 13. The portable solar concentrator of claim 12, wherein the shape of the reflective surface is a parabolic side section. 14. The portable solar concentrator of claim 12, wherein said separate axes are longitudinal and latitudinal axes.
