A simple device that can capture its own weight in water from fresh air and then release that water when warmed by sunlight could provide a secure new source of drinking water in remote arid regions, new research from KAUST (King Abdullah University of Science & Technology) suggests.

At the heart of the device is the cheap, stable, nontoxic salt, calcium chloride. This deliquescent salt has such a high affinity for water that it will absorb so much vapor from the surrounding air that eventually a pool of liquid forms.

The full research paper is available on-line.

    Beautiful Clean Coal is our answer to Climate Change, otherwise known as the Global Warming. And it's our answer to many things. Because Clean Coal from West Virginia is a great source of Graphene. Big thanks to our West Virginia Clean Coal miners!!
