    This device can squeeze water from thin air — even in the driest areas of the world.

    The device you see above can produce nearly 3 liters of water per day, and researchers say they can make it work even better. The key to their success is a family of crystalline powders called metal organic frameworks, or MOFs. MOFs are compounds consisting of metal ions or clusters which form 2D or 3D structures. They are a special type of polymers, often porous. To the naked eye, they would look pretty much like sand, each granule riddled with holes into which gases and molecules of interest can be selectively allowed to pass or blocked. Then, they’re brought in and compacted, making it possible to store a lot of gas in small containers.

    Omar Yaghi, a chemist at the University of California, Berkeley, first demonstrated MOFs 20 years ago. Since then, he and others have developed several types of applications for them, including membranes that absorb and later release methane, acting as a carbon tank for cars. In total, over 20,000 types of MOFs have been developed, but one, in particular, is extremely interesting.

    In 2014, Yaghi and his colleagues synthesized an MOF that is extremely efficient at absorbing water from thin air, even under extremely low humidities (like those in the driest places on Earth) — now, they’ve taken it a step further. Working with Evelyn Wang, a mechanical engineer at the Massachusetts Institute of Technology (MIT) in Cambridge, he turned this idea into a functional device which basically harvests water from thin air. In a study published in the journal Science, they describe the mechanism, showing that it can pull 2.8 liters of water from the air over 12 hours — even in conditions with 20 or 30 percent humidity.

    It's a great idea but someone somewhere will wreck it by using it for something else
    Then the technology will be taken away from us until such time as a profit can be squeezed out of it and it'll be banned to export it to poor countries, just like solar panels and equipment

    We won't see this in our lifetimes
    Just like neighborhood nukes

    This world somehow manages to snatch defeat from the jaws of victory, time after time after time

    These things and constantly proposed and debunked. You can't draw water that isn't there to be drawn, and the energy required ALWAYS exceeds that of just transporting in water from somewhere else

    Yep, nuked by the TPTB, just like those carburetors that run on water.

    Whata buncha naysayers.
