  • Patent number: 9732987
    Abstract: A modular two axis solar tracking system contemplates a first fixed base and a slidable/rotatable arm fixed to the first fixed base. The fixed base includes a primary linear actuator and a first movable element movable along a fixed axis. A second linear actuator is fixed at one end of the first movable element and an inverted J-shaped element is movable along a second axis that is perpendicular to the first axis. A second fixed base is disposed in an open area surrounded by an open area defined by a U-shaped lower portion of the inverted J-shaped element. A slidable rotatable arm includes a projection coupled to the inverted J-shaped element that together with the first and second actuator move collection at the ends of the slidable/rotatable arm or arms to track the sun.

  • Patent number: 9441858
    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.

  • Patent number: 9174890
    Abstract: The present invention relates to a method for converting carbon dioxide into hydrocarbons by reacting magnesium with carbon dioxide to obtain magnesium oxide and carbon, reacting the carbon with hot water steam to obtain hydrogen (H2) and carbon monoxide, reacting hydrogen and carbon monoxide according to the Fischer-Tropsch method, or reacting the carbon obtained with earth alkaline metal oxide to obtain earth alkaline metal carbide and carbon monoxide, wherein the earth alkaline metal carbide is then reacted with water to obtain acetylene and earth alkaline metal hydroxide.

  • Patent number: 8419904
    Abstract: Systems and methods for solar water purification are described. In one exemplary aspect, the system includes a sun-tracking reflecting mirror unit, and a two-axis Fresnel concentrator mirror unit to collect sunlight reflected from the sun-tracking reflecting mirror unit and focus the sunlight. A central water purification boiler module includes a heating zone upon which the sunlight is focused by the two-axis Fresnel concentrator mirror unit. The focused sunlight heats the water contained therein to create steam which is redirected to heat water coming into the boiler and to condense as purified water.
