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.
The system works in a two-stage cycle that first captures water from the air with an absorbent material and then extracts it within a sealed chamber using heat from the sunlight.
The organized collection of dew or condensation through natural or assisted processes is an ancient practice, from the small-scale drinking of pools of condensation collected in plant stems (still practiced today by survivalists), to large-scale natural irrigation without rain falling, such as in the Atacama and Namib deserts.
Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.
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.
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.
