    • @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.

Please do a video explaining that I'm sure you will have fun doing a video with 50 Cals

  • 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.

    alfpolo29alfpolo296 hours ago
  • 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.

  • 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!
