D.E.W. Desert Electricity and Water

D.E.W. (Desert Electricity and Water) is a nonprofit organisation whose challenge is to transform arid areas into fertile lands. We have a system that extracts large amounts of water from the air and pours it into the ground. Our system is able to passively generate a big amount of pure water from the air (million litres of water per day). The system can be fully passive and doesn't use any electromechanics. It can be placed anywhere, is autonomous and emits no pollution. It can be built using materials available in large quantities and which exist almost everywhere (iron, aluminum, sand, cotton wool, glass, mirrors).
