Water From Air

Magic water harvesting machine:

Amazing. A gizmo which sucks the air in, then sucks the water out of the air, and then spews out clean fresh water. 500 Gallons of it – a day.

Pretty cool. Getting clean water is a large problem throughout the world. Unfortunately this is not the solution yet – each machine costs $500,000. still for the right situations this is useful. FEMA bought 2.

Its precise workings aren’t public, but they use a chemical process similar to the one that causes salt to absorb moisture from the air (and clump up your saltshaker). The water-harvesting technology was originally the brainchild of the Pentagon’s Defense Advanced Research Projects Agency (DARPA), which sought ways to ensure sustainable water supplies for U.S. combat troops deployed in arid regions like Iraq.

Darpa gave millions to research companies like LexCarb and Sciperio to create a contraption that could capture water in the Mesopotamian desert. But it was Aqua Sciences, that was first to put a product on the market that can operate in harsh climates.
