Breathe underwater without an oxygen tank
Alon Bodner has developed a breathing apparatus that will allow breathing underwater without the assistance of oxygen tanks. The new invention supplies oxygen by extracting the small amounts of air in seawater spread by waves and underwater currents.
A rapidly rotating centrifuge extracts oxygen by creating low pressure inside a small sealed chamber. Calculations shows that a one kilo rechargeable battery can provide a diver with about one hour of diving time.
Cool Or What?
