The presented agricultural invention and apparatus here shown and disclosed was developed for peoples in undeveloped countries, peoples affected by the changing climates to reduce water usage and reduce electricity usage, bringing more water retention in the soils used for growing food all year round, for heating and cooling purposes of food and peoples living areas. The invention presented here is an apparatus used with a generation of electricity apparatus that utilizes a plurality of solar photo voltaic panels in a rack mounting structure utilizing various apparatus for increasing water irrigation, reduce water usages, and reduce electricity usage costs and supply at a specific spatial point area. The invention was developed to help people in rural un developed areas as well as cities and industrial growing areas. Also included is an autonomous Virtual Currency related split payments apparatus for a mining aspect of rewarded distributions to poverty, animal, wildlife and environment beneficiaries.

A water purifying and desalination system includes solar concentrators that receive a sunlight and direct the sunlight toward many locations. Heat collection elements positioned at the of locations absorb and convert a solar radiation into thermal energy. Some of heat collection elements include perforations to facilitate a state change in a heat-transfer fluid having a high salinity. A condenser condenses a portion of the heat-transfer fluid using a portion of the heat-transfer fluid as its coolant.

A method for grease purification is disclosed. The method comprises steps of: S1, feeding crude grease into a grease hydrolysis column to be hydrolysed so as to obtain aqueous phase, organic phase, and middle layer substances between the aqueous phase and the organic phase; S2, feeding the organic phase and the middle layer substances in the grease hydrolysis column into a flash stripping column to be flashed so as to obtain vaporized products and non-vaporized products; and S3, feeding the vaporized products in the flash stripping column into a separation column to be separated so as to obtain fatty acid. By this method, fatty acid with a high purity can be obtained; glycerin can be obtained as a co-product; and high value-added nutrients in the grease can be collected. Therefore, the use value of grease can be greatly improved.

A water tank that is used with a solar air conditioning system and provides a supply of cold water for in-dwellings radiators of the system. In one embodiment, the tank application can begin at 32 F degrees and drop down to many degrees colder, such as, but not limited to, minus 100 F degrees. In one non-limiting embodiment, the tank can hold 2000 gallons of water.

Apparatus for producing water (1) from ambient humidity comprising a heat exchanger (10), comprising a desiccant (11a′) of ambient humidity, a solar thermal panel (30) for giving up heat to the heat exchanger (10) and the solar thermal panel (30) being a concentrated one.

A solar concentrator (100) comprising: a base (190); a framework (170), the framework (170) being hingedly joined to the base (190) such that the framework (170) can be rotated relative to the base (190); and a plurality of mirrors (110) arranged relative to a first axis (200) of the framework (170), such that all of the mirrors (110) are located on one side of a plane which contains the first axis (200), each mirror being fixed to the framework (170) and each mirror being arranged to reflect light travelling parallel to the first axis (200) towards a common focus which lies on the first axis (200).

A greenhouse, for cold weather climates, is configured with a gable that is offset toward the north wall and therefore the south extension of the roof, from the gable to the south wall is longer than the north extension. A greater amount of light can enter through this south extension and the inside surface of the north wall is configured with a reflective surface to allow light to be more uniformly distributed around the plants. The north wall may no widows and may be thermally insulated to prevent the greenhouse from getting too cold during the night. A ground to air heat transfer (GAHT) system may be configured to produce a flow of greenhouse air under the greenhouse for heat transfer, to moderate the temperature of the greenhouse. A thermal medium may flow to a thermal reservoir for heat exchange with the conduits of the GAHT system.

Technologies are disclosed herein for a thin heat exchanger through which coolant may be pumped. The heat exchanger may include an envelope and a heat conduction layer provided over the envelope. The envelope may include one or more channels formed therein. The channels formed between the envelope and the conduction layer may extend the length of the heat exchange layer and be configured to carry coolant therethrough. The heat exchange layer may include an inlet manifold on a first end and an outlet manifold on another end opposing the first end. The inlet manifold may allow the flow of coolant into the heat exchange layer and the outlet manifold may allow the removal of the coolant from the heat exchange layer. Coolant flow may be controlled by a suction pump operating under computer control based at least in part on sensor data.
