New device harvests fresh water from the air

Water, water everywhere, but not a drop to drink. Until now The air around us is filled with minuscule droplets of water—vaporized H2O that’s too tiny to drink—unless it condenses around a cooler surface like a cold water glass in summer. But Israeli startup Water-Gen has developed a technology to harvest the air’s humidity in warm climates, producing potable water at a cost of less than ten cents a gallon.
