Only a fraction of the Earth’s water is drinkable—an estimate from the U.S. Geological Survey puts all of the world’s freshwater at just 2.5 percent of the total global water. But much of that freshwater is locked up as ice in glaciers, ice caps and permafrost. People get most of their water from rivers, which make up only 0.49 percent of surface freshwater. What if we could diversify and pull water from the air, instead?
