Wow! How about just using the water all around you? So the science fiction idea is to remove water from your blood, crack it into hydrogen and oxygen and then inject the oxygen back into your blood? With this wild process I'd think that to replace your lost volume of blood you'd need to drink a nice glass of water occasionally. :-)
Has anybody built a sub with 1ATM air normally, but the option to use 2+ATMs
for the occasional deeper wreck dive? Of course, nitrogen bubbles would have
to be dealt with as per scuba diving.
