Two-thirds of the earth’s population may soon need more water, especially in arid regions. Australia, India, North Africa, and areas of the United States and Mexico, to name but a few, are rich in sun but poor in water. Using the sun to power a metal-organic framework (MOF) that acts like a sponge to soak up humidity, Omar Yaghi of the University of California Berkeley and Evelyn Wang of MIT, and team, have developed MOF-801 that could be carried in a suitcase, set up in a solar view, and immediately produce enough water for a family of four.
