Making Water From Thin Air
A company that developed technology capable of creating water out of thin air nearly anywhere in the world is now under contract to nourish U.S. soldiers serving in Iraq.
The water-harvesting technology was originally the brainchild of the Pentagon's Defense Advanced Research Projects Agency, which sought ways to ensure sustainable water supplies for U.S. combat troops deployed in arid regions like Iraq.
But it was another company, Aqua Sciences, that developed a product on its own and was first to put a product on the market that can operate in harsh climates.
Sher said he is "not at liberty" to disclose details of the government contracts, except that Aqua Sciences won two highly competitive bids with "some very sophisticated companies."
He also declined to comment on how the technology actually works.
"This is our secret sauce," Sher said. "Like Kentucky Fried Chicken, it tastes good, but we won't tell you what's in it."
He did, however, provide a hint: Think of rice used in saltshakers that acts as a magnet to extract water and keeps salt from clumping.
"We figured out how to tap it in a very unique and proprietary way," Sher said. "We figured out how to mimic nature, using natural salt to extract water and act as a natural decontamination.
"Think of the Dead Sea, where nothing grows around it because the salt dehydrates everything. It's kind of like that."

A wind-driven device could provide an unlimited water supply by harvesting water from the air, says its Australian inventor.
But critics are asking if it's too good to be true.
Dr Max Whisson, a retired medical specialist turned inventor, says he has designed a highly efficient wind turbine that can run a refrigeration system to cool air and condense moisture from it.
"The wind carries in the water and [provides] the power required to separate that water from the wind," says Whisson, who is based in Perth.
He says there is a huge amount of water in the atmosphere that is replaced every few hours. This means the whole world could just use water from the air without disrupting the environment.
Whisson says the system would even harvest significant amounts of water in areas with low humidity.
He says a 4 metre square device could extract an average 7500 litres of water a day.
In his design, moisture-laden air enters the system and is cooled by a drop in pressure behind the wind turbine blades, says Whisson.
The air then flows into a chamber containing refrigerated metal plates covered by a non-wettable surface that causes water droplets to run off immediately into a collection point.
WASHINGTON -- The Army is nearing the end of testing a pump that will make potable water from vehicle exhaust.
Doug Snowden, an engineer from Hamilton Sunstrans, displayed the two-part pump at the Army's Tank and Automotive Command booth at the Association of the U.S. Army’s annual convention in Washington, D.C., Oct. 6.
"All we're simply doing is recovering the water that's present in the fuel," Snowden said.

You could make a water concentrate, easier to transport over distances

hey genious, what do you think the army is doing with the invention mentioned in the OP?
Actually Ice has a larger volume than water

You could make a water concentrate, easier to transport over distances then you just add water.
