The Hydroid Aquabreather is a futuristic scuba diving helmet that is designed to make use of the chemistry of metal superoxides to make it possible for scuba divers to explore depths of up to 42 metres for up to an hour without having to lug heavy cylinders and other conventional scuba diving gear.
The Hydroid Aquabreather uses a mix of sodium superoxide and potassium superoxide to allow for ample absorption of carbon dioxide, which is then converted into oxygen. This special mixture is stored in replaceable cartridges, each of which can allow around an hour of diving.
This scuba diving helmet works by ensuring that air is not exhaled into the outside environment but rather circulates inside and enters the cartridge, where it is converted into oxygen.
Available for preorder, the Hydroid Aquabreather may represent the future of scuba diving.
