New submarine tech breath of fresh air
It probably doesn’t bear thinking about if you’re claustrophobic, but on a submarine the only thing in shorter supply than space is oxygen. Submarines are never more vulnerable than when they’re on the surface and exposed, so navies around the world are focused on improving the underwater endurance of their subs. From the moment a sub closes its hatches and dives deep it's full of people emitting carbon dioxide. To help them, we’re testing a new way of removing carbon dioxide from a sub’s atmosphere while it's submerged.
