      I thought he was going to say the headphones button Is so cool because they pause the music and turn up the outside noise to hear people better, not just to pause music like my $40cdn Poms that are a knockoff of Airbuds that are a knockoff of airpods lol but good enough.

    23:35 It's a continuous batch process, so the liquid is pre-heated before moving into the boiler so as not to dramatically reduce the temperature of everything already in the boiler.

    It's been 30 years since I served on a submarine, and I can close my eyes and still smell amine and diesel fuel. Oh and wives HATED the smell. Most guys were made to strip outside before being allowed in the house, and then were made to scrub repeatedly in the shower before even being able to be in the same room with their wives. The smell never completely comes out of fabric.

    That MEA reminds me of human bood. Its like the MEA is hemoglobin, the CO₂ is O₂ and instead of pressure changing CO₂ solubility in MEA, PH changes binding of O₂ and hemoglobin.

    hahahahaha they don't burn candles! hahahahaha those are for emergency situations! the environmental systems on the subs are MORE than capable of producing all the oxygen (and hydrogen) needed for the coners and the engine room.... i'll just leave it at that... if you're lighting those candles for real.... you're probably in a REAL BAD situation...

    I'm not going to watch the video but just wanted to say that if you run an electrical current threw water from point a to point b you get oxygen bubbles in the center. Now leave this technology to the imagination & you can invent many things to help a human breath under water. You can even create a rebreather under water is done correctly and safely.

    23:40 The misterious preheater is most likely a heat exchanger. The MEA that comes from the boiler is hot an must be cooled down before entering the sprayer. That heat is transferred to the rich MEA before entering the boiler.
