摘要:
Melting metals using solar energy is not new, but is new is making the technology ergonomic, and easy to use. Invented is a half-shell-parabolic-dish reflector, which has in front an adjustable flat planar reflector. When the sun is overhead, the sunlight reflects off the flat planar reflector to a half-shell-parabolic-dish, which redirects the light to a crucible for smelting metals, which is also the focus of the sunlight. The entire assembly rotates on top of a turntable, which can be steel wheel, floating on compressed air, bicycle wheels, or other suitable methods. The entire assembly rotates about a crucible located at the focal of the sun's rays. A smaller version of the smelter can be used for solar cooking.

A method and apparatus for controlling weeds using concentrated solar energy is disclosed. Solar energy may be concentrated by Fresnel lens and directed by manual or automated methods at surfaces of weed plants to heat portions thereof causing damage. Shutters or other devices may be used to direct, and control intensity of concentrated, solar energy, such control preferably applied before significant concentration. In some embodiments, solar energy concentration apparatus may be integrated with ground, air, or water vehicles which may use solar photovoltaic cells for electric power for propulsion and other purposes. Vehicles may use global positioning satellite (GPS) receivers or other methods and apparatus, including video cameras, for navigation and selection of areas (e.g., row middles), plants, or portions of plants to be exposed to concentrated solar energy. Air vehicles may use hydrogen gas electrolyzed from water condensed from humid air to replenish hydrogen gas lost from containment vessels.

A solar oven that includes a multiple zone concentrator and a diffuse focal zone is disclosed. The solar oven may include at least one element of symmetry. In such a case, the diffuse focal zone substantially aligns with the oven symmetry element. The diffuse focal zone may include a central region and a peripheral region. The multiple zone concentrator has at least one reflective member for directing radiation to a plurality of portions of the diffuse reflective zone. The reflective member has a first reflective zone and a second reflective zone. The first reflective zone may include at least one of zonal element of symmetry offset from the oven symmetry element. Also, the first reflective zone has a profile that captures and directs radiation to at least a portion of the peripheral region of the diffuse focal zone. The second reflective zone is adjacent a first end of the first reflective zone and has a profile that captures and directs radiation to at least a portion of the central region of the diffuse focal zone. A receptor support is provided for supporting a receptor substantially within the diffuse focal zone. Optionally, a booster adjacent a distal end of the first reflective zone is provided for directing additional radiation to at least one of the peripheral region and the central region of the plurality of portions of the diffuse focal zone.

A solar appliance includes first and second double-wall bowls, each having an outer wall and inner wall spaced inwardly of the outer wall with at least partial vacuum therebetween. The first and the second double-wall bowls each having an opening that provides passage between an interior and an exterior thereof. The outer walls are at least translucent and the inner walls have an opaque solar radiation absorbing material. A gasket detachably mates the first double-wall bowl with the second double-wall bowl at least proximate respective rims thereof in inverted relationship. A vessel with a rim is positionable in the interior of the first double-wall bowl, with the rim of the vessel extending beyond the rim of the first double-wall bowl to help secure the second double-wall bowl to the first double-wall bowl. A vent, for example in the gasket, can vent the interior to the exterior.

Devices, systems, and methods relating to providing a portable, rechargeable vessel for collecting, storing, and recovering thermal energy are provided. In one aspect, vessel includes a structure defining a well and an open-top portion at the top of the well; a phase-change material, wherein the phase-change material is disposed in the well, the phase-change material being configured to change phase at temperature in the range of 110-700° C.; one or more thermally-conductive fins interleaved in the phase-change material; and a thermally-conductive heat transfer plate disposed at and substantially covering the open-top portion of the structure, in direct thermal contact with the one or more fins, thereby allowing the transfer plate to directly exchange thermal energy with the phase change material.

A gas processing system includes an input gas supply, an output gas storage container and/or an inlet to a secondary reactor, and a solar-thermal reactor. The solar-thermal reactor uses a solar collector to focus sunlight onto a reactor, the reactor having a housing that encloses a reaction chamber, a catalyst arranged therein, an inlet for receiving the input gas and an outlet for expelling the output gas. Sunlight is focused by the solar collector to heat the reactor and thereby chemically convert the input gas from the gas supply into the output gas that can be stored in the output gas container or directed towards the secondary reactor.

The present invention is directed to time and energy efficient drying of organic matter. The present invention features a drying system which may include a solar tower, a shredder, and an input conveyor for transporting the organic matter to conveyors positioned in a cascading configuration. The system may further include sensors for collecting information, and a control system for receiving the information to determine a speed of the conveyors. The system may further include an output conveyor for transporting the organic matter from the conveyors to a storage. The system may further include water condensers to reclaim water evaporated from the organic matter to be stored and repurposed. The system may further include a solar power system for converting sunlight into power for the system. Sunlight may cause a thermal gradient within the solar tower, causing air in an upper portion to be hotter than air in a lower portion.
