Scientists may have found a way to provide millions of people around the world with fresh water.
Developed by a team of researchers at the Massachusetts Institute of Technology and the University of California, Berkeley, the prototype system is able to convert humidity in the air in to liquid water using a special metal-organic framework that traps air inside tiny pores.
When sunlight heats it up the water molecules trapped inside are released and condensed – producing several liters of water on average every twelve hours.
“It takes water from the air and it captures it,” said MIT mechanical engineer Evelyn Wang. “It doesn’t have to be this complicated system that requires some kind [of] refrigeration cycle.”
“Now we can get to regions that really are pretty dry, arid regions. We can provide them with a device, and they can use it pretty simply.
