A method and apparatus worn by a user for controlling weeds using concentrated solar energy is disclosed. Solar energy may be concentrated by Fresnel lens over the wearer and directed by manual methods by the wearer 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 of the solar energy. In some embodiments, solar energy concentration apparatus may be integrated with solar photovoltaic cells for generating electric power for purposes such as an electrical temperature sensor, a camera and video display device for viewing underneath a crop canopy, control of solar intensity and other purposes.

A solar design generation system is configured to design a solar panel or photovoltaic (PV) system for the roof of building. A server includes processing circuitry configured to receive information from a remote device, including an address corresponding to a building having a roof, automatically generate a solar design in real time based on the received information, and display the solar design to a user. The user can interact with the solar design in various ways to accommodate, implement and calculate various design changes, design rules and electricity generation (production) estimates.

A system and method for the removal of volatile components from a liquid or a slurry containing solids and liquids and using a screw conveyor or auger system that transfers solid/liquid slurries through an elongated tube heated by solar energy from a parabolic solar trough. The system flashes off the volatile component then counter-currently flows that vapor back into the hollow pipe inside of the augur creating a Multi-effect or Multi Flash device which greatly improves the overall efficiency of removal of the volatile material.

A system for producing electricity from solar energy is provided. The system includes a solar panel for disposing such that solar radiation impinges thereon. The solar panel includes fluid pipes configured for heating fluid therein by the solar radiation. The system further includes a fluid container in fluid communication with the fluid pipes, having an inlet configured to receive heated fluid from the solar panel and an outlet configured to transfer fluid back to the solar panel; a gas line disposed in the fluid container, the gas line having a liquid gas being configured to evaporate by the heat generated by the fluid and to increase thereby pressure in the gas line; and a turbine having a rotor configured to convert rotating motion to electricity, the turbine being configured to receive evaporated gas from the gas line and the evaporated gas is configured to rotate the motor.

A solar collection system includes an absorption refrigeration system to generate water from atmospheric moisture, and to do so without the use of an electrically operated compressor. At least a portion of the solar energy captured by the solar collection system is used to operate the absorption refrigeration cycle. The absorption refrigeration cycle provides cooling that causes water in the atmosphere to condense into a liquid that can be collected and used for various applications. As one example, the collected liquid can be used for the cleaning of the solar collection system of contaminants like dust or bird drippings. In other applications, the water can be used outside the solar collection system including, but not limited to, irrigation, drinking, and other industrial purposes.

A system of solar thermal collectors and an HVAC controller draw heated air through a solar thermal absorbing needle-punched propylene geotextile with limited permeability to air flow, into the interior of poultry livestock house. In various embodiments, the poultry livestock house is divided into zones. Groups of collectors are joined with breather holes on opposite sides of the collectors and solid sides on the ends of each group. Groups of collectors serve each zone of the poultry livestock house. In an embodiment of the system the Environmental Optimization System (“EOS”) provides a system for the intelligent control and monitoring the broiler poultry livestock structure environment through the utilization of a variety of environmental and livestock behavior sensors, apparatus for controlling the thermal collection and existing interior heating/air conditioning/ventilation (“HVAC”) systems, and Internet or cloud based intelligent control and monitoring capabilities of the system. In various embodiments central sensor data aggregation is utilized to provide improved optimization control for livestock zones within individual structures based on data from multiple structures.
