State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.
An atmospheric water generator is a machine that extracts potable water from the humidity in air using a refrigeration or a desiccant. Condensing moisture by refrigeration requires a minimum ambient temperature of about 10–15 °C (50–59 °F), while desiccant adsorbers have no such restriction.
However, rather than using refrigeration to condense water vapor, it uses a metal–organic framework to trap water vapor in the night and then uses the heat from solar energy to release the water from the framework during the day. [11] [12] Her research group has also developed a solar powered desalination system in producing clean water. [13]
An air well or aerial well is a structure or device that collects water by promoting the condensation of moisture from air. [1] Designs for air wells are many and varied, but the simplest designs are completely passive, require no external energy source and have few, if any, moving parts.
Researchers at MIT have been able to build on a concept inspired by the Stenocara's shell and first described by Oxford University's Andrew Parker.5 They have crafted a material that collects ...
An energy tower (also known as a downdraft energy tower, because the air flows down the tower) is a tall (1,000 meters) and wide (400 meters) hollow cylinder with a water spray system at the top. Pumps lift the water to the top of the tower and then spray the water inside the tower. Evaporation of water cools the hot, dry air hovering at the top.

At top: "Water vapor in the air is condensed by cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air." Water vapor comes out of the air by REDUCING the pressure of the air, as when a pressurized soda is opened, and the 'cloud' of water is formed after the sudden depressurization of the air between the ...
