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."
Really depends on what the cost (per kilogram) of this new powder would be? And how long (how many liters) can it be used? We could give smartphones and cell towers to everyone in the world, but if they don't upkeep their infrastructure, they'd be worthless. Same here, if the people using the powder can't afford it, or it requires intricate maintenance, then the technology will fail. If it is too expensive, then it will fail also. I wonder if the cables are there to monitor, or if they are there to add something to the system?
is fine no problem if you're in nice climes and 60 pounds. . . . idiots COME HERE ! to a hard environment, just like the survivalist vids-kids/zombies, TOTAL ! and I MEAN ! TOTAL BRAIN DEAD# s! to the unimaginable extreme like how are they alive, oh daddy owns ... oh just look in North south valleys , find water , oh this that and start fire(have never tried in extremes WE HAVE come talk jack!), on and on and on and ON! of B R A I N DEAD ARMY SURVIVALIST THAT HAVE NOT BEEN AROUND THE WORLD OR EVEN ACROSS A STATE from the south. Shoud be illegal spouting trip e like that. Will kill peop... [More]
From the article: "A recent test on a roof at MIT confirmed that the system can produce about a glass of water every hour in 20 to 30 percent humidity." Huh. That's impressive.
Well..... Considering that the Sahara desert has about 25% relative humidity, I wonder if their "glass of water", is based off their testing at probably more like 50% to 70% humidity, and they extrapolated? One thing to check, is that the amount of water recovered is directly proportional at all humidity levels, or if it has some function to how much will come out of the air based on the current level. Perhaps desert air at 25% would tend to retain the water regardless? Not trying to disrespect their invention, but trying to be skeptical enough not to just swallow a lemon.
So they made a better dehumidifier. If these go to market we'll have people claiming the oceans will dry up because everyone is making the air so dry that evaporation will increase. Which will be good as global warming.....I mean climate change will melt all the ice caps making the oceans rise so more water is available. Wait! That sounds like a perfect solution for glob...I mean climate change! I also predict static shocks will increase and explosions cased by staic sparks where there's too much dust in the air from being too dry. Yeah - we need the sarcasm font.
Scientists at the Paperdyer Foundation may have found a way to provide millions of people around the world with fresh sarcasm produced out of thin air stories !
Has to be a way to use sheets of plastic in giant towers in that way UV protected all that and in the collection cisterns on the side of Mt. KangchenjungaWAQHATEVER !/killimanjaroo? they'd have gravity run piping like the Romans you know.
