Scientists have just create a remarkable machine that could solve a major world crisis and help millions of people.
Scientists have just achieved an amazing breakthrough with the invention of a machine or device that could prove to be pivotal in the battle against a major world crisis. Researchers at the Massachusetts Institute of Technology and the University of California at Berkeley have created a device that can pull water literally from thin air, and do it in a much more efficient way than past machines.
This new machine would use less power than past technologies that did the same thing, and it would be able to operate in drier environments, a major boon to the many millions who live in developing areas and who don’t have easy access to clean water.
The machine works by combining organic compounds with metals to create a powder that soaks up water vapor. Scientists use heat to release the pores once they become filled with water. Further development of this technology could lead to larger and even more efficient machines pulling water out of the air just about anywhere in the world where it is needed.
“This is a major breakthrough in the long-standing challenge of harvesting water from the air at low humidity,” said Omar Yaghi, one of two senior authors of the paper, who holds the James and Neeltje Tretter chair in chemistry at UC Berkeley and is a faculty scientist at Lawrence Berkeley National Laboratory. “There is no other way to do that right now, except by using extra energy. Your electric dehumidifier at home ‘produces’ very expensive water.”
“One vision for the future is to have water off-grid, where you have a device at home running on ambient solar for delivering water that satisfies the needs of a household,” said Yaghi, who is the founding director of the Berkeley Global Science Institute, a co-director of the Kavli Energy NanoSciences Institute and the California Research Alliance by BASF. “To me, that will be made possible because of this experiment. I call it personalized water.”
