    Billboard Water

    A simple solution to a scarce resource. Actually, not sure how technically complicated the whole thing is, what with the purification needed, but the idea is very simple.

    "It takes water from the air and it captures it...

    Water Out of Thin Air? It Can Be Done, Say Scientists
    April 13, 2017 — People living in arid, drought-ridden areas may soon be able to get water straight from a source that's all around them — the air, American researchers said Thursday.
    Scientists have developed a box that can convert low-humidity air into water, producing several liters every 12 hours, they wrote in the journal Science. "It takes water from the air and it captures it," said Evelyn Wang, a mechanical engineer at the Massachusetts Institute of Technology (MIT) and co-author of the paper. The technology could be "really great for remote areas where there's really limited infrastructure," she said.

    The system, which is currently in the prototype phase, uses a material that resembles powdery sand to trap air in its tiny pores. When heated by the sun or another source, water molecules in the trapped air are released and condensed — essentially "pulling" the water out of the air, the scientists said. 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. Companies like Water-Gen and EcoloBlue already produce atmospheric water-generation units that create water from air.


    A glass is filled in with drinking water in Paris, April 27, 2014. Scientists have developed a box that can convert low-humidity air into water.

    What is special about this new prototype, though, is that it can cultivate water in low-humidity environments using no energy, Wang said. "It doesn't have to be this complicated system that requires some kind refrigeration cycle," she said in an interview with Reuters. An estimated one-third of the world's population lives in areas with low relative humidity, the scientists said. Areas going through droughts often experience dry air, but Wang said the new product could help them still get access to water. "Now we can get to regions that really are pretty dry, arid regions," she said. "We can provide them with a device, and they can use it pretty simply." The technology opens the door for what co-author Omar Yaghi called "personalized water."

    Yaghi, a chemistry professor at University of California, Berkeley, envisions a future where the water is produced off-grid for individual homes and possibly farms using the device. "This application extends beyond drinking water and household purposes, off grid," he said. "It opens the way for use of [the technology] to water large regions as in agriculture." In the next few years, Wang said, the developers hope to find a way to reproduce the devices on a large scale and eventually create a formal product. The resulting device, she believes, will be relatively affordable and accessible.

    This is certainly nothing new.

    Luke Skywalker's uncle ran a whole farm on a dessert planet with those things.
    Amended for our nitpicky forum lawyer types:

    Public service announcement: the 1st amendment means the government can't arrest you for what you say. It doesn't mean anyone (not the government) has to listen or provide a platform. It doesn't shield you from consequences. If you are yelled at, cancelled, boycotted or banned your rights are not being violated, it's just that the people (not the government) listening think you're an asshole.

    Boy scouts have learned how to condensate water from the air for a very long time.

    But then the Star Wars universe was long, long ago....

    MAKE A SOLAR STILL FOR WATER

    You can get about a quart of water a day by this method. Dig a cone-shaped hole about 3 feet deep and 3 feet in diameter and line it with fresh-cut green plants. Place a cup in the bottom of the hole and cover the hole with a sheet of plastic. Secure the plastic with rocks placed around its edges and put a small stone in the center of the plastic to create a valley above the cup. When the sun warms the still, plant moisture will condense on the plastic and drip into the cup.
