The US Navy is developing a new prototype deep-dive suit that helps save helium. Existing dive suit solutions can be extremely wasteful when it comes to the helium/oxygen gas mixture that divers breathe, prompting US Navy scientists at the Naval Surface Warfare Center Panama City to develop this high-tech solution.

The US Navy scientists' deep-dive suit involves the recycling of a certain amount of exhaled helium. While exact details on the mechanism are yet to be released, it is believed a rebreather mechanism will be used to remove carbon dioxide from the mix, allowing the diver to breathe the recycled helium.

Ultimately, this helium-saving deep-dive suit means that the length of dive missions -- including emergency and reconnaisance missions -- can be extended, leading to better outcomes.
