“The program focused on creating water from the atmosphere using low-energy systems that could reduce the overall logistics burden for deployed forces and provide potable water within the reach of the war fighter any place, any time,” said Darpa spokeswoman Jan Walker.
To achieve this end, 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 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.
“People have been trying to figure out how to do this for years, and we just came out of left field in response to Darpa,” said Abe Sher, chief executive officer of Aqua Sciences. “The atmosphere is a river full of water, even in the desert. It won’t work absolutely everywhere, but it works virtually everywhere.”
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 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. [Full Article]
