Remember that great film The Abyss? Remember Ed Harris having to learn to breath oxygenated liquid? Well it turns out that theory may just well turn into fact thanks to Arnold Lande, a retired American heart and lung surgeon.
"Lande envisages a scuba suit that would allow divers to inhale
highly-oxygenated perfluorocarbons (PFCs) – a type of liquid that can
dissolve enormous quantities of gas. The liquid would be contained in an
enclosed helmet that would replace all the air in the lungs, nose and
"The CO2 that would normally exit our body when we breathe out would
be “scrubbed” from our blood by attaching a mechanical gill to the
femoral vein in the leg."
This is awesome, where do I sign up to get a gill attached to my leg??? I'll take two!!!
