DARPA have been tasked with cutting the amount of the water the army has to carry by half. So where is the other half coming from? Well, they are going to take it from the exhaust fumes of their vehicles (see below), or just pluck it out of thin air! Here's how...
Water from the Air
"Our extraction of airborne water involves manipulation of surface chemistry using nanotechnology," William Warren, president of Sciperio, said in an interview
Based in Oklahoma, Sciperio Inc. carry out research funded by a number of agencies including DARPA, MIPT and AFOSR. During their $4 million research they have successfully trapped water vapor by passing air over liquid lithium chloride.
Reverse osmosis is then used to extract fresh water, and advanced pumps used to make the water palatable.
