      @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.

      @Gw Builder Thank you for the input/clarification. My thoughts were leaning towards the use of ultra efficient low power consumption LEDs in a spectrum of sufficient fine tuning to obtain maximum O2 generation, perhaps utilizing arrays of Fresnel lenses. Just seems plausible. I feel like it could be utilized to oxygenate the vessel at least in a supplemental role with other methods that are currently implemented, even if a 25% level of impact is realized.

    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?

    So, to explain the pre-heating of the MEA, it is done by a heat exchanger. Think of it like a radiator, on one side you have the recently boiled Lean MEA, on the other you have the cold Rich MEA. The thermal energy is transferred across the heat exchanger, simultaneously cooling the Lean MEA and heating the Rich MEA. It's more efficient in several ways. 1) if you already have something hot nearby, why waste the energy heating it up if you can sap heat from something you want to cool. 2) cool MEA absorbs CO2 better, so you spend less energy cooling it before it is sent back to the absorbing tower.

    To those wondering why you need to heat up the MEA. Any physicists among us thought : "Why is this not a perpetuum mobile ?" The secret lies in the heating. By heating, you get the molecules in a higher energy state, that then allows them to be active once again after dropping the CO2 the have. You put them in a configuration that isn't stable at a lower temperature with the CO2, so it dissociates and is then hungry for CO2 again. Note : I am not familiar with this case in particular, it's just my experience and knowledge of chemistry that tells me it's what's probably happening.
