Colonists on Mars could one day generate fuel and oxygen from saltwater on the Red Planet, a new study finds.
The novel technology behind this advance could also help submarines generate oxygen from seawater on Earth, researchers said.

Any water they find on the Red Planet will therefore prove invaluable, as they can use electricity and other methods to break water down into both hydrogen and oxygen.
