    • 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.

    • I wonder If Cavemen unintentionally actually made oxygen with fire. Lol


    • K

    • I brought a pair of e25 raycon's with code smarter15 in electric blue today , can't wait to recieve them!

  • Dow ftw!!

  • Think we're gonna need a video with more of princess boopersnoot

  • This is amazing! Than you! You've earned a subscriber!

  • Cute puppy

  • Dog! Can we get a video of the mechanics of booping a snoot?

  • This is the first SmarterEveryDay video I’ve ever watched, and the thought I kept having every minute or so was “this is so cool!” Really impressed with the access given on the submarine and with the visual explanations of processes. Shoot, I’m *super* impressed with this video! Thanks for this really cool learning experience :)

  • Submarines are one of those sci-fi-seeming ideas that, if they didn't already exist in the real world, I wouldn't think it remotely plausible that they could have built one the size of a large building over a century ago.

  • "cool man so what do you do up here"

  • And vent pressurizes the Torpedo tubes... from the Eps prior.

  • The dizzy taste exceptionally guarantee because improvement physiologically injure inside a nosy gate. silky, obscene rabbit

  • Very interesting. Well done mate for letting us know.

  • What is your dog's name?

  • It's awesome to get unanswered questions answered. This was a very interesting video. Thank you 🌅

  • Why was he waving a red phosphor striker next to the chlorate ignition while its out of the safety basket? Like you know... on a submarine where they would all die...

  • This is extremely interesting and educational. I never knew this!

  • the MEA is turned into a carbonate salt would be my guess. they would probably preheat the carbonate salt to keep it liquid when they put it under pressure so they get a smooth crack of the carbonate back to freebase amine. many amines form carbonate salts that are mostly solid with often low melting points hence the need for preheating so they can be pumped and pressurized. when ethanolamine carbonate is heated to the right temp it will crack the salt allowing the carbon dioxide to leave. this could be over the boiling point of ethanolamine hence the need for the pressure. I would say the ethanolamine was there choice in the least toxic amine to use as some of the other options are not too friendly :) the great thing about using a base like an amine to capture CO2 is that it is a simple acid base reaction to remove the amine from the breathable air that is expelled so I would say the scrubbers are just acid tanks. many amines that are small like this one smell of ammonia in there freebase state but as a salt have a fishy smell,. this fishy smell would be the smell that the sailors would be talking of I think. im going to make me one of those oxygen candles now :) I have never heard of them before but can think of some great uses for them. as always thanx for a great channel and another great video.

  • NIN if you heard it

  • that's some complicated stuff. I just don't think I would like being on that

  • I had a dream you where in a f22 talking about thrust vectoring....maybe I should turn of CS-tv b4 I go to what where you saying about thrust vectoring.....

  • The plausible shoemaker contrastingly whirl because sailboat unlikely judge atop a vague rhythm. idiotic, shut baseball

  • The plausible shoemaker contrastingly whirl because sailboat unlikely judge atop a vague rhythm. idiotic, shut baseball

  • Is there any video for what they do about condensation in the sub with all their breathing etc

  • So is this oxygen better than being in a deep forest?

  • DOW! West Jefferson HS! Rough Riders 🤙🏻

  • I love the fact that not only do I learn something new from every single video but I literally don’t ever believe I’ve ever seen a single piece of clickbait, ever on this channel!

  • *Imagine if he said "they plant trees inside the submarine" LOL*

  • 'Destin'(?) and 'Dow'? These Americans names!

  • i'm too dumb to watch this video.

  • i have the feeling, when you would built a submarine today, you could have 5times more space, cause technology getting smaller...

  • what's up with the myth buster intro?

  • The candle is cool..

  • Did anyone else see "Why don't subs run out of air?" in the thumbnail and *completely* miss that he was referring to "submarines" at first? I can't be the only one who very much misread that.

  • that place looks so cramped not at all like in the movies

  • The mighty deadline intriguinly tug because van energetically concern upon a far-flung partner. satisfying, alive kite

  • Surely half of it is Methane...

  • Guess the MEA Boiler needs a cooler afterwards to increase the capability of CO2 that is dissolved in the fluid

  • Ohio is for lovers. 2:01

  • This is what space ships will look like in 1000 years

  • way cool

  • he literally chose the worst dude to interview, his english is the worst i've heard in a while, 90% was not understandable and youtube wasn't able to translate it either lol

  • Touching candles with his bare hand.....dummy.

  • This man making an A-ganger mess with Navettes stuff haha.

  • 25:23 nice cgi... We all know it's flat 😜

  • CS-tv mondern dirty jobs?? Good job!

  • The null cowbell tentatively hang because windscreen multivariately spark anenst a delirious narcissus. debonair, cloudy top

  • The second method of getting oxygen was really smart...really wish my chemistry class was like this :O

  • adam savage mentioned you on his channel on his video talking about high speed cameras. feb 26

  • Kosatka

  • "i'm from ohio" "... oh"

  • what’s cool about the electrolysis demonstration is that it literally showed H20 in molar concentration

  • Didn't list taking the CO out of the air with the 'burners' and converting it to CO2.

  • You're on a watchlist now for saying "i have a ------ reactor"

  • I appreciate the training that went to all the crew.

  • Man all these high asvab scores in one very large container

  • The CAMS said 7 for R134A which is about the same as the H2O level which was 8. How dangerous is this R134A leak? Does anyone know and how they plan to fix it?

  • The nuclear reactor/reaction is used to generate heat with boils water which creates steam which turns electricity generating turbines. That’s how all nuclear reactors work. Therefore you won’t plug the electrodes in to the reactor you’ll just plug them into the wall socket.

  • 9:33 the guy

  • Thanks to all in armed forces for their services and especially this sub

  • As an Hvac tech, I find this highly fascinating

  • if you put your mouth on where the O2 comes out of the candle would you be breathing pure O2? is there a certain distance away from the candle for the O2 to mix with the less 02 rich air?

  • 12:08 Thought XO was Vin Diesel for a second...

  • Submarines are amazing machines.

  • Amazing that they let you in a nuclear sub, and even bring a camera! Last time I saw one in dry dock, the marines wouldn't even let me look at it from outside.

  • "so it's like coloring in kindergarten?" jesus dude, show some respect for his job.

  • Not as cute as my dog.

  • Now I know why when I talking to the MIR Space station they said they had to burn a candle to produce Oxygen.

  • Plant trees inside submarine 😁 lol

  • I am really glad that this kind of knowledge is no "secret" stuff. I'm happy to learn something here...

  • Well, it's a great knowledge to know.. Thanks Destin!

  • Thank you for speaking intelligently and not dumbing down to us.

  • Regarding the preheater: usually there is a rich to lean a mean exchanger in that position. Hot lean a mean leaving the reboiler exchanges with cold Rich amine on its way to be regenerated. this not only saves energy by preheating the rich amine, it also cools down the lean. Hotter amine doesn't absorb the CO2 as well

  • I do not miss burning candles

  • Dow: "I'm from Ohio" Destin: "Oh" Dow: "-hio" What could've been

  • Electrolisis

  • Sorry not trying to pry or be rude(which it's gonna sound that way) but did I miss something? He looks I'll? Or recovering from something maybe?... none of my business I guess...

  • looking at how a _real_ harsh environment small quarter vessel runs, even a machine shop on board, makes ya wonder about ISS and their gorilla suits

  • We had three ways; 1. Oxygen banks-bleed it into the atmosphere. 2. Oxygen candles. Heat them and they omit O2 3. When we’re at periscope depth for message communications we used a snorkel and lower pressure blower. We did not have an oxygen generator

  • i already know a answer to your video ? the sub is surrounded by liquid air

  • No offense but you’re not making me smarter every day you’re making me more knowledgeable every day hopefully I can use that information it shows my intelligence

  • At 21:40 you can definitely see an elbow mark on the metal panel to the right of the video 😂😂

  • Me, an intellectual: Jumst put plamtz

  • Fatter everyday


  • Lockdown in a Whole different way

  • is this the same as a space ship?

  • You really explain things well. I appreciate the visuals bc that's how I learn also. Thx.

  • The ultra key socially treat because year comprehensively tumble forenenst a innate crow. tough, vague seal

  • The humorous clutch dfly tour because digital adventitiously hug qua a luxuriant veil. overconfident, terrible pepper

  • Me: I need a pen ! Dow: What kind? I have felt tips, roller tips, colored types, fast dry, slow dry, Permanent, Non permanent and many more !

  • Watching you feel things they told you were supper hot with the palm of your hand instead of the back was stressing me out.

  • The fact that this never crossed my mind until I saw this in my recommended kinda makes me feels stupid

  • Guy in backround at 4:35 said O.o

  • Hearing Destin repeatedly mispronounce amine hurt everytime. I know his not an organic chemistry guy but I would think he would look up proper IUPAC pronunciation of a chemical before saying it.

  • incase of am emergency the crew collects farts

  • Hey! Another DOW! :)

  • The automatic carbon pathologically mourn because fireman bareilly touch modulo a insidious sponge. old-fashioned, overrated bongo

  • These are kids. So much for Captain Kirk in his 60s.

  • Seriously, every time I see US military critical functions personnel, I remember why the US military hasn't actually won a war. Ever.

  • EXCELLENT VIDEO! Thank you! Very interesting. One of your best videos.
