It's called the 'Triton Oxygen Respirator', a small but remarkable device that will do away for the need to carry bulky tanks on dives, and allow the dives to last much, much longer than can be had with conventional equipment.

It's amazing function lies in the design of tiny, nano scale 'artificial Gills', a series of small strands or threads have tiny holes along their length, which are smaller than water molecules, and can effectively separate the Oxygen from the water while diving, on demand.

Thinking ahead, apart from applications in the Scuba industry, this could well find its way onto private, commercial and military ships as a safety device issued to all crew and passengers, aircraft too if they have to ditch into the sea.

With slight modification, it could also be used on land, by firefighters in smoke filled building for example.
