Water harvested from diesel exhaust

A new technology to harvest drinkable water from diesel exhaust could help the U.S. military become more nimble and mobile as it engages in conflicts around the world.

Warfare is hot, dirty, and exhausting work that requires a steady stream of water to slake thirst, prepare meals and maintain healthy hygiene — up to nearly 7 gallons a day per person.

Supplying that water to soldiers increases vulnerability to military personnel and limits the tactical use of field troops, according to researchers at the Department of Energy’s Oak Ridge National Laboratory who are developing the new technology.

Their solution is to use the fuel that the military burns to run its tanks, Humvees, generators and other machines that power field operations. When fuel is combusted, it gets oxidized and produces carbon dioxide and water.
