For many of us, clean, drinkable water comes right out of the tap. But for billions it’s not that simple, and all over the world researchers are looking into ways to fix that. Today brings work from Berkeley, where a team is working on a water-harvesting apparatus that requires no power and can produce water even in the dry air of the desert.
*snip*
It’s essentially a powder made of tiny crystals in which water molecules get caught as the temperature decreases. Then, when the temperature increases again, the water is released into the air again.

>>This box sucks pure water out of dry desert air<<
Ladies and gentlemen I present:
“The Stormy.”
No,to name it that there'd have to be a garden hose mentioned.
Haven’t they been using this method in Israel for some time?
Looks like Uncle Owen finally found a droid that understands the binary language of moisture evaporators.
If it’s too good to be true, it probably is.
Efficiency? MOF life?
I’ve long thought that as soon as some sort of cost-effective solar powered water desalination is invented, life on Earth will get a lot better. But getting from the air is even better!
“This box sucks pure water out of dry desert air”
Yes, it’s been around for at least a decade but perhaps these Berkeley researchers have made an improvement.
EnviroNazis will still complain about it. Just like Wind Turbines morphing from Green Salvation to Bird Choppers, this invention will be decried as the cause of droughts and floods in the wrong places at the wrong times. It denies moisture to plants, which starves herbivores. It unfairly benefits the rich.

Yep. If this new technology can be scaled up, it could be a game-changer. As a side note, I wonder how long it will be before some activist claims (without proof, of course) that this method will contribute to Global Warming.
Unfortunately the tiny crystals can only be found
in the habitat of the endangered desert tortoise.

I’m a tech kind of guy, so I find those questions interesting. I wonder how you would calculate the device’s efficiency, given that the device is essentially powered by the sun.
Maybe: How much water is actually captured / How much water theoretically can captured (?)
As to MOF life, I don’t know what that is.
Interesting link there. But the Ecoloblue device must be plugged into a power source of some kind. The Berkeley folks say their device needs no power source except the sun - sunrise followed by sunset.
Has anyone told the Gates?

Speaking of water....in our County we are have a water, er, “problem” for certain at risk populations...being told not to drink it...and NOTHING can fix it, not boiling (makes it worse), filtering, distilling, not even a berkey filter...aaaggghhhh
