    @Stan Ervin The idea is plausible; however, the lower the efficiency of the plant the more toxicity is generated. I think that is where the problem begins because the benefit verse the compound detriments create a negative cycle. In the natural environment those conditions can be overcome, but in a dependent environment where the oxygen generation is a necessity, those negatives make a no go situation. I like your determination, there is definitely an answer somewhere.

    The nuclear reactor/reaction is used to generate heat with boils water which creates steam which turns electricity generating turbines. That’s how all nuclear reactors work. Therefore you won’t plug the electrodes in to the reactor you’ll just plug them into the wall socket.

    Regarding the preheater: usually there is a rich to lean a mean exchanger in that position. Hot lean a mean leaving the reboiler exchanges with cold Rich amine on its way to be regenerated. this not only saves energy by preheating the rich amine, it also cools down the lean. Hotter amine doesn't absorb the CO2 as well

    We had three ways; 1. Oxygen banks-bleed it into the atmosphere. 2. Oxygen candles. Heat them and they omit O2 3. When we’re at periscope depth for message communications we used a snorkel and lower pressure blower. We did not have an oxygen generator

    instead of releasing it into the atmosphere, Those guys should store the hydrogen into tanks at the very least. it's useful, and they've got to create tons of it if they make so much oxygen via electrolysis. have it done, I'm sure hydrogen could be useful for the army loll.

    Very interesting. Great content. So, by my calculations, at the time you were filming, the oxygen percentage for the sub was about 19%. That is the O2 torr / total torr. 19% is fine for sustaining human life but I wonder why they don't shoot for 21% (what we typically breath at sea level). Any idea?
