are using "fog nets" to harvest moisture as an alternative to scarce natural rainfall.
A famous fictional depiction is the moisture farms of Tatooine seen throughout the Star Wars
films.
Water vapor
Water vapor or water vapour , also aqueous vapor, is the gas phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Under typical atmospheric conditions, water vapor is continuously...

- Atmospheric water generatorAtmospheric water generatorAn atmospheric water generator , is a device that extracts water from humid ambient air. Water vapor in the air is condensed by cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air.
