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.

    Desalination is a good idea, but it is expensive, has high energy requirements, and the water needs to travel hundreds (or thousands) of miles to get to everyone who needs it.

    This isn't intended to replace desalination. It's a very low cost, low energy solution that works where the water isn't. Maintenance on this is basically nonexistent.
