    do they need to replace gases like nitrogen?

    @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.

    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.

    Should be classified info, we do not want adversaries to steal our submarines' oxygenated technology, it is crucial because we want our adversaries submarines to surface for air often so we can detect and track them, especially CHINA, they are master in chemistry but also master in stealing IP and technology so we need to be more careful with sharing or educating these kind of military technology. My point here is to protect our military technology from foe.

    You’d think it’s easy, there’s water everywhere. It has oxygen in it, and co2 can remove carbon to leave oxygen from that too... you just need a way to expel the hydrogen and or carbon.

    Do we see how they monitor and manage heat on-board? Seems like the submarine is producing a lot of heat. Do they just use a refrigerant to transfer heat to the surrounding water? And if so, how much do they have to insulate the ship? If the power cuts out what's their backup cooling system?

    I see my boy at 13:00 got that sneaker chit so he doesn't have to wear boots huh 😂 Edit: I learned something new myself. Apparently on submarines boots aren't required. I believe I saw the XO wearing sneakers so I got curious. It seems submariners aren't required to wear boots underway. I'm sure there's other reasons but sneakers are quieter than the Navy issued boots and obviously that's paramount when in the Silent Service. I never spent time on a submarine, I was either afloat or attached to aviation so there's a lot I don't know about submariners. Even being in the Navy for almost eight years, you still taught me something new even if inadvertently!

    Man, I served on the Tennessee (an Ohio class sub) from 02-05. Cool to see somebody talk about this. One of the most surreal experiences was being on patrol and slowly having O2 levels drop. We got increasingly tired. When we surfaced and got back to a normal oxygen level, everybody on the boat was wired and couldn't sleep for a few days.

    12:45 "We call these Clinkers. Honestly I have no idea why we call them Clinkers" Clinker bricks are clay bricks that are too close to the heat source in the kiln. They come out overcooked, a darker color and usually misshapen and made a metallic ringing sound when you 'clinked' them together. They were rejects and discarded until their use was popularized during the Arts and Crafts architecture movement. Modern kilns are able distribute their heat more efficiently so they don't produce clinkers in the same way, but you can still buy bricks that are molded to give that misshapen and fire glazed look.

    1. Out the tube as it pushes out the torpedo. 2. Torpedos have control surfaces, navigate themselves and are self-propelled. They don’t need a spin to keep them straight any more than the submarine itself needs one.
