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.
