Abstract

Solar heating systems and methods are described. In one aspect, a system is described that includes multiple mirror row holders, with each row holder configured to hold a row of mirrors at angles to track sunrays and reflect the rays onto a focal point. Each row holder has a single pinion device of multiple pinion devices associated with the multiple row holders. The system also has a sun tracking latitudinal slider (STLS) rack configured to interface with each pinion device on a respective mirror row holder. This interface tilts the mirrors in each row holder an amount to adjust mirror angles to reflect latitudinal sun motion to concentrate rays of the sun onto the focal point. The system also includes an azimuth adjustment mechanism to control mirror angles with respect to the sun to reflect sun motion during daylight.

First claim

The invention claimed is:

1. A solar heating system comprising:
multiple mirror row holders, the mirror row holders having a fresnel-shaped cross-section, each mirror row holder of the mirror row holders hold a row of mirrors at fixed respective angles to adjacent mirrors to track sun rays, each mirror row holder having a single pinion device of multiple pinion devices associated with the multiple mirror row holders, the singular pinion of each mirror row holder being located at the middle of each mirror row holder; the solar heating system being operatively coupled to a substantially circular base;
a sun tracking latitudinal slider (STLS) rack operatively configured to interface with each pinion device of multiple pinion devices simultaneously, the STLS rack being comprised of a threaded rod, the interface automatically tilting the mirrors in each mirror row holder through the rotation of the STLS rack, said rotation causing each mirror row holder to tilt a latitude amount to adjust mirror angles to reflect latitudinal sun motion during daylight and to concentrate rays of the sun onto the focal point;
a heat exchanger including a focal point, the heat exchanger being operatively coupled to a fluid input portion and a heated fluid output portion;
an azimuth adjustment mechanism to control mirror angles with respect to the sun to reflect sun motion during daylight and to concentrate rays of the sun onto the focal point; and,
a controller configured to:
simultaneously adjust the angles of the mirrors using the STLS rack to track the latitude motion of the sun and concentrate sun ray reflections onto the focal point; and
simultaneously use the azimuth adjustment mechanism to adjust mirror angles to track azimuth motion of the sun and concentrate sunray reflections onto the focal point.

2. The solar heating system of claim 1 , wherein each pinion device is a gear and wherein the STLS rack is made to interface with the pinion gears.

3. The solar heating system of claim 1 , wherein each pinion device is a wheel with magnets on its diameter and wherein the STLS rack is an electromagnetic device made to move the pinion magnets.

4. The solar heating system of claim 1 , wherein the STLS rack is made with magnets on its length, and wherein each pinion device is an electromagnetic wheel that responds to magnets sliding in proximity on the STLS rack.

5. The solar heating system of claim 1 , wherein each pinion device is a wheel with magnets and wherein the STLS rack is an electromagnetics linear motor that interfaces with the pinion devices.

6. A solar heating system comprising:
multiple mirror row holders, the mirror row holders having a Fresnel-shaped cross-section, each mirror row holder of the mirror row holders hold less than a row of mirrors at fixed respective angles to adjacent mirrors to track sun rays and reflect the tracked rays onto a focal point, each mirror row holder having a single pinion device of multiple pinion devices associated with the multiple mirror row holders, the singular pinion of each mirror row holder being located at the middle of each mirror row holder; the solar heating system being operatively coupled to a substantially circular base;
multiple sun tracking latitudinal slider (STLS) racks operatively configured to interface with each pinion device of multiple pinion devices simultaneously, the STLS rack being comprised of a threaded rod, the interface automatically tilting the mirrors in each mirror row holder through the rotation of the STLS rack, said rotation causing each mirror row holder to tilt a latitude amount to adjust mirror angles to reflect latitudinal sun motion during daylight and to concentrate rays of the sun onto the focal point;
a heat exchanger including the focal point, the heat exchanger being operatively coupled to a fluid input portion and a heated fluid output portion; and
an azimuth adjustment mechanism to control mirror angles with respect to the sun to reflect sun motion during daylight and to concentrate rays of the sun onto the focal point
a controller configured to:
simultaneously adjust the angles of the mirrors using the STLS racks to track the latitude motion of the sun and concentrate sun ray reflections onto the focal point; and
simultaneously use the azimuth adjustment mechanism to adjust mirror angles to track azimuth motion of the sun and concentrate sun ray reflections onto the focal point.

7. The solar heating system of claim 6 , wherein each pinion device is a gear and wherein the STLS rack is made to interface with the pinion gears.

8. The solar heating system of claim 6 , wherein each pinion device is wheel with magnets on its diameter and wherein the STLS rack is an electromagnetic device made to move the pinion magnets.

9. The solar heating system of claim 6 , wherein the STLS rack is made with magnets on its length, and wherein each pinion device is an electromagnetic wheel that responds to magnets sliding in proximity on the STLS rack.

10. The solar heating system of claim 6 , wherein each pinion device is a wheel with magnets and wherein the STLS rack is an electromagnetics linear motor that interfaces with the pinion devices.
