When kids learn about the planet’s water cycle, they’re taught a simple concept: our atmosphere is filled with water vapor that has evaporated from the bodies of liquid water we see around us. When the vapor’s temperature gets low enough, it gets turned back into water.
The presence of that vapor becomes especially apparent in the summer, when droplets collect on glasses of ice water and air conditioning units drip onto unsuspecting passersby.
An Israeli company called Water-Gen does not think of that condensation as a byproduct; instead, it has built machines specifically designed to create and harvest as much condensation as possible. Using a system that uses a set of plastic “leaves” to funnel air in various directions, the team has developed water generators that appear to create pure drinking water out of nothing.
“The target is to extract water from the air with minimum energy,” founder and co-CEO Arye Kohavi tells Business Insider. “We think our solution can solve the problem on the level of countries. It’s an immediate solution — governments don’t need to spend decades to make a big project.”
Water-Gen is one of seven Israeli companies presenting technological innovations at the United Nations General Assembly this week.
The company currently makes three sizes of water generating machines, each of which must be plugged into a power source. At 80 degrees and 60% humidity, the biggest can yield about 825 gallons per day, but Kohavi says the technology is easily scalable. The company’s medium sized unit produces 118 gallons per day under the same conditions, and the smallest — which is intended for use in a home or office — produces just under 4 gallons per day.

Well used rope please- new ropes are so scratchy :)
Hard to see how this is economically feasible, but in places where fresh water is scarce, sounds like a winner.
Semipermeable membranes are probably cheaper.
