Breathe like a fish

An Israeli inventor has come up with a brilliant way of breathing underwater without compressed air. The system itself uses the air stored within the water and will hopefully not require divers to carry the heavy tanks anymore. While this is a great breakthrough, there is yet to be a prototype and only the scientific principle has been proven to work. Yet, this is exciting since this could mean a lot in changing the world of rebreathers and diving equipment.
