Nano Product: Lungless
350 million years after crawling from the sea, the Lungless suit will bring us back. Inspired by fish gills, the Lungless Aquatic Respiration Suit uses millions of cascading sheets of nano-membrane to filter oxygen from the water and deliver it to the diver’s mouth. Enjoy unlimited, tank-free exploration on the other 70% of the planet.
From the NANO Supermarket product collection. Designer: Sean Serafini. Enabling technology: Nano structures. Feasibility: Medium.

Is the suit tested? in retail?
I like it
The suit is a possible vision of the future, when nano-technology might be advanced enough to let us breathe underwater.
I want one!
Exactly how advanced would nanotechnology have to be for this to be possible? It seems to me that this would work through nanomaterials and research is making great strides in that area recently, so would this be relatively possible in the next 5-10 years?
