A Wind Turbine Turns Dry Desert Air Into Precious Drinkable Water There’s water everywhere on earth, but most is undrinkable or inaccessible. A new kind of wind turbine takes the water in the air and puts it into a form we can imbibe.
Water is everywhere, but there’s hardly a drop to drink. The vast majority of the Earth’s surface is either arid or salty ocean. Only 2.5% of our planet’s water resources are fresh, and just a tiny tiny fraction (0.007%) of that is available for direct human use.
Yet one of the largest sources of water is around us every day: the air. Even our deserts are awash in moist air. Israel’s Negev hits an annual average relative humidity of 64%. That translates into 1.2 centimeters of water for every cubic meter of air.

The problem, of course, is that it’s rarely moist enough to rain. Scientists have spent decades exploring ways to con
