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.
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]
Watergen was founded in 2009 by entrepreneur and former military commander Arye Kohavi and a team of engineers with the goal of providing freely accessible water to troops around the world. [ 2 ] Following the acquisition of Watergen by billionaire Michael Mirilashvili , in 2016, the company turned its attention to addressing water scarcity and ...
Researchers have developed a wireless system that can transmit data from an underwater source to the air. The approach, known as translational acoustic-RF communication (TARF), sends a sonar ...
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.
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 ...
