I find that Excedrin works better than Tylenol for the headaches! :)

I was intrigued by the idea of (sci-fi) small radioactive or body-powered
implants that take the water in your blood and would start to produce oxygen
to release when 02 drop.
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.
Why would you increase the internal pressure? For structural reasons to offset the ambient water pressure? On PSUBs there's been a lot of interesting discussion of ambients versus 1atm designs and also hybrids. My impression is that there are a number of operational and design complexities with ambients that balance their simpler structural requirements. Still no "free lunch" in submarine design...
