I didn't know exactly where this fits in so I chose here. A little information "One idea that is being researched to prevent the need for saturation diving and decompression at great depths is liquid breathing, which was also shown in "The Abyss." Instead of breathing gas, the diver breaths a non-compressible, liquid perfluorocarbon compound that contains oxygen.". http://science.howstuffworks.com/science-vs-myth/everyday-myths/question640.htm So is liquid breathing possible? It seems so... But what's the time table it would be used? Would it be usable to say just the Navy? Would you have tried this? It seems kinda neat. Have you seen Abyss, its a old movie I re saw it today, that is what got me thinking about liquid breathing. So has anyone got a clue who is all doing this type of research? Has it been tried on humans? Or is this a "doomed project" What's your thoughts an ideas on this, anyone?
