    In 1979, a former nuclear submarine commander visited a hot site about 5 miles from me. Not too long after that, another former nuclear submarine commander gave a talk in my neighborhood. Three Mile Island. But they didn't come to talk about subs. I wondered about subs and how they worked but figured if I searched the details, I'd have all the Alphabet Agencies on my butt. In my travels I have met people of all trades, including clandestine ones but never met a submariner. Thanks for this excellent presentation. It has helped satisfy some of my curiosity about subs.

    Hey Destin I just wanted to thank you for your videos. I love to watch and seldom miss an episode. Your passion and excitement for learning is so refreshing. We are so fortunate to have information and ways to learn practically anything, at our finger tips via the internet. I really don't think the younger generation fully understands what a privilege this is. Being that I'm on the back side of 40 I am amazed at how easy it is to find information and learn these days. Anyway I just wanted to thank you for your videos and dedication to education. Keep the awesome videos coming.

    The question of how to get RID of the Carbon Dioxide is much more interesting! There was some stressful discussion of this in Das Boot, and also in Twenty Thousand Leagues Under the Sea! So it has been an issue for around a hundred years, and still interesting to anyone who is interested in diving, working in hazardous atmospheres, or "a better life in space for everybody".

    How do they handle the air mixture? Does the air over time become pure oxygen or do they also add nitrogen to the mix? A pure oxygen atmosphere is very flammable so I imagine they need to do something about it.

    The preheating process is likely to streamline the process so the amount of time it takes to scrub the CO2 is reduced in the primary boiler scrubber. Think of it like boiling hot water vs. starting with cold water. I could be wrong but that could be one reason.

    One thing that has always had me wondering is how do they replenish the "nitrogen" in the atmosphere of the ship? Sure, you can make oxygen by electrolysis and scrub out some of the carbon dioxide but nitrogen is the biggest fraction of our atmosphere at around 78%. You can't stay down constantly and just replenish oxygen. I assume there is some outgassing somewhere in the system and the nitrogen content would go down and the oxygen content would go up until you have flash-fires. You would also build up some other more rare components of the metabolic processes of people (methane, ethane and a dozen or so others that I have forgotten). Periodically you need to snorkel and do an air exchange to purge those out.

    Forgive my ignorance, i'm normally quite astute. For one, i understand a nuclear sub can work below as long as the food lasts. These candles are new to me, and they are burned at regular intervals, my question is, how many do they go to sea with, and how are they stored? Food storage/candle storage, what is the ratio. Did i miss something? It seems these are essential, as is food.

    A clinker is an artificial stone created by some chemical process. Initailly used for bricks, later for the material ground into cement. Makes sense here. But why is the chemical reaction regarded safer than having pressurized oxygen on board? Yes, and for long-term use, the MEA cycle is better than the LiOH cannisters.
