20090000613 | Solar power harvester - A solar energy harvester comprises: an elongated stationary solar irradiance converter assembly; a concentrator comprised of a substantially flat array of flat reflective heliostatic slats disposed at tilt angles to concentrate the sun onto the converter assembly, said slats each rotating in elevation about a north-south axis; sun sensor detecting the efficacy of concentration as the sun traverses; and control circuitry and drive motor positioning the collector in elevation according to the sun sensor so that the slat array tracks and faces the sun whenever the solar incident energy is greater than a selectable threshold level. Solar power is harvested as either electricity or thermal energy or both. In the case where both electric and thermal energy are harvested the electricity produced is according to the limits of photovoltaic efficiency and the remaining solar irradiance is harvested as useful heat. In a preferred configuration the concentrator and its mount and drive mechanism are all typically located within a housing or enclosure having a transparent upper surface and a reflective north wall, which together provide complete environmental protection for all elements mounted within the enclosure. The converter assembly may be internal or external to the to the enclosed housing assembly. | 01-01-2009 |
20090000653 | Solar power harvester with reflective border - A solar energy harvester comprises: a planar solar harvester panel serving to absorb sunlight and convert it to useful power such as electricity and/or heat; a planar north (in the northern hemisphere) wall which is specularly reflective on its south side, running east-west and positioned adjacent the north end of the harvester panel. The reflective north wall may be considered to create a second, equal, virtual harvester panel to convert additional energy, or alternately to create a virtual sun to illuminate the harvester panel from the north. The solar energy harvester effectively doubles the output of useful power of a prior art solar harvester panel alone. | 01-01-2009 |
20090025711 | Solar water vapor ejector - A water vapor ejector comprises a desiccant disposed in a communication path to a green house enclosure. In the day time and under sunlight exposure, the green house enclosure heats up, which dries the desiccant and generates a flow to the outside ambient through a pressure difference. The moisture trapped in the desiccant is then released to the outside ambient. In the night time, the green house enclosure cools, which generates a flow to the inside of the enclosure. The desiccant traps the moisture within the flow, ensuring a moisture-free enclosure. The cycle re-starts in the next morning when the enclosure heats up. The diurnal cycle removes the water vapor present in the enclosure and delivered to the exterior of the enclosure. | 01-29-2009 |
