I was doing some reading on the subject after watching The Abyss again... there's lots of posts on liquid breathing systems, you can find them with a quick search.
As for the using the o2 already in water, there is some research being done on the subject. I read about an israeli doctor who's developing a similar form of technology. (This may be fake, i didn't have time to verify). Supposedly, it's a type of mini centrifuge. THe idea is an application of Henry's law (gas disolving in liquid vs pressure). The centrifuge changes the pressure of the water it takes in from around the diver, and releases the air that is disolved in the water. according to the article i read, there is, even at deeper depths, something like at least 1.5% dissolved air in seawater, which is enough to satisfy small and big fish alike.
Maybe sometime soon we'll see some sort of apparatus to enable us to suppliment a small air tank with this water delivered o2, and prolong our divetimes... who knows.
Personally, I'm just looking forward to when they can surgically give me some gills. Like in water world. That would be friggin' sweet.
