Israeli water tech company Water-Gen, which has developed a technique for creating drinkable water out of air, is providing its technology to military units in seven nations including the U.S., PolicyMic reported recently.

Water-Gen’s solar or electric-powered water generators, which can sit on the ground or in vehicles such as tanks, produce between 10 and 20 gallons of fresh, cold, drinking water per day. The Tel Aviv-based company originally designed the generating unit for hydrating troops in extreme combat situations.

The generating process begins with an air filtering unit facing outside that extracts humidity from the air and works like an air dehumidifier to remove toxins from the moist air. The clean air then enters GENius, the company’s unique heat exchanging system that produces water from the humidity. The water collects at the bottom of the unit and fills up water tanks before flowing to a tap.

“Taking water from the atmosphere has not been done correctly. The tech has not changed for many years. It was based on bad assumptions, the tech was inefficient and it was very expensive,” said David Gillo, Water-Gen’s VP of business development. “We brought it to a place where it’s efficient, energy-saving and affordable enough where it’s being seriously considered.”
