ExoLung Turns Body Motion Into “Unlimited” Underwater Air Supply
12th December 2019
There’s a lot of ground between puttering around with your face strapped to a snorkel and managing the dangers, equipment, certification and expenses of scuba diving. Surface-supplied diving systems fill some of this space by strapping you to a breathing hose that plunges deeper than a snorkel but without some of the complications of scuba. Typically these systems rely on some form of compressed air, but a new prototype from Austria uses a more sustainable air supply: you. The ExoLung translates the diver’s swimming motions into air movement, keeping breathing air flowing so long as the diver keeps swimming.
