Water from air

Strategy Page:

In a major logistics breakthrough, a U.S. company, Aqua Sciences, has developed a system that can extract water out of the air, even if the humidity is as low as 14 percent. It does this using salts, and can produce water for less than a dollar a gallon. The system currently available is contained in a twenty foot long tractor trailer unit, and turns out 600 gallons a day. Why is this a major logistics breakthrough? Because in dry climates, about a third of the supply tonnage moved to American troops consists of water. And the movement alone costs up to $40 a gallon, depending on how bad the roads, or security situation, is. So each Aqua Sciences unit would save thousands of dollars a day in logistics costs for units in hard-to-reach areas. There are larger water extraction units, that can be moved by flat bed truck, that are even more efficient, producing much more water, for as low as 30 cents a gallon....

In World War I when the British defeated the Turks in what is now Israel, the British forces laid a pipeline across the Sinia Peninsula to provide water for the troops and animals in the march to battle. Here is a map of the area which shows movements during the 1956 Suez crisis.

The innovation that Strategy Page discusses could have a considerable impact on enemy strategy in this war, which to the extent it has focused on US troops it has been with logistic units rather than combat units.
