Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H₂O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Water is the name of the liquid state of H₂O at standard ambient temperature and pressure. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds are formed from suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water moves continually through the water cycle of evaporation, transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea.

Hydrate formation and growth for hydrate-based desalination by means of enriching water to be treated
InactiveUS6890444B1Saturation pointQuick mergeOrganic chemistryAuxillariesDihydrogen oxideDesalination
Water to be desalinated or otherwise purified is enriched by having hydrate-forming substance dissolved into it, without causing hydrate to form. Hydrate kernels are brought into contact with the enriched water to be treated, and the hydrate kernels grow outwardly into the water to be treated by incorporating dissolved molecules of the hydrate-forming substance and water from the water to be treated. Thus, substantially solid, generally spherical hydrate masses, which are preferred for hydrate-based desalination or purification, can be formed. Hydrate-forming substances can be dissolved into the water to be treated under conditions not conducive to formation of hydrate, such that hydrate does not form, using vigorous means. Hydrate-forming substance is also preferably dissolved into the water to be treated under conditions suitable for hydrate to form, but without causing hydrate to form, e.g., by being infused into the water to be treated using infusion membranes.

Autonomous water source
InactiveUS7467523B2Reduce salt contentQuality improvementRoot feedersGeneral water supply conservationForest industryWater source
An autonomous water source (AWS) for extracting water from ambient air and delivering it to a plant to support growth. The system is based on an adsorption-desorption-condensation (ADC) cycle using a sorption material to extract moisture from ambient air and condensing the water vapor driven off from the sorption material by subsequent heating and followed by condensation. Liquid condensate produced in this process on the condenser is collected and delivered by gravity to a plant to reduce thermal stress and to support growth. The invention provides a sustainable source of irrigation water for agriculture and forestry, including areas where no water resources exist or are not economically viable. It can be tailored in size, and therefore, output capacity, reflecting the desired water requirements of a particular application, and can be used to replace most agricultural situations now reliant on surface water drip feed systems. The device is simple, rugged, invulnerable to rain, snow, and freezing conditions, and can be designed to last for many years without service as there are few moving parts and power required for operation is provided by sunlight.
