Other than throwing chlorine in the pool to have clear water to swim in, people now use salt systems.. We all know that chlorine is bad for every living creatures, ... So why do we still use it the " purify " the water we swim in ?!!..

These young people are absolute experts in their fields and I am extremely proud of them! Most folks have no idea how important each job in the military is for the overall function of the military. May God continue to bless all the men and women in our military and America! Thank you all for your service and thank you, again for making this video.

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.

  • I feel like Dow is the kind of guy that knows a ton, but just isn't the best at speaking. He's probably got all of his duties down to the point where he could do them with his eyes closed (Not literally, of course, being in a submarine and all that) in addition to knowing enough that he gets to work on the Nuclear Sub in the first place, but explaining things is a completely different beast from just knowing things, so he talks a bit slower while arranging his thoughts, and occasionally thinks faster than he speaks. Same, submarine dude, same.

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.
