US military wants to deliver water to troops by sucking it out of the air
The US military is researching ways to capture moisture in the air and deliver it to troops as drinking water in arid environments, the Defense Advanced Research Projects Agency (DARPA) revealed in a recent statement.
DARPA, the Pentagon's research arm, has launched the Atmospheric Water Extraction (AWE) program to explore ways to extract potable water from the air in quantities sufficient to meet troop's demands for drinking water in less hospitable areas, such as desert regions.
The US military has troops serving across the Middle East in countries like Iraq, Syria, and Afghanistan, as well as parts of Africa. The military currently relies on deliveries of bottled water or the purification of fresh and salt water sources for drinking water in these locations.
Neither "are optimal for mobile forces that operate with a small footprint," Seth Cowen, the AWE program manager at DARPA, said in a statement, adding that "the demand for drinking water is a constant across all Department of Defense missions, and the risk, cost, and complexity that go into meeting that demand can quickly become force limiting factors."

The new AWE program will focus on developing a compact, portable device designed to provide an individual soldier with a daily supply of potable water, as well as a larger device that can be transported on a standard military vehicle and meet the demands of an entire company.
DARPA is putting an emphasis on advanced sorbents, materials able to absorb liquids, that can rapidly pull water from the air over thousands of repetitions and quickly release it without requiring significant amounts of energy, the agency said in a statement. Additionally, AWE solutions will need to be suitable for highly-mobile forces.
"If the AWE program succeeds in providing troops with potable water even in arid climates, that gives commanders greater maneuver and decision space and allows operations to run longer," Cohen said, adding that this technology could potentially "diminish the motivation for conflicts over resources by providing a new source of drinking water to stressed populations."
