    • 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!

  • At start i thought wth this video is 30 mins, ended up watching fully.

  • Summary 26:00 , i recommend watching the whole video...

  • These guys know what they are doing

  • “You’re Oxygen creator” I love that line of the guy so much

  • Dow is very well at his job he’s so cool

  • Yo, bein on a submarine sounds like a bit of work

  • What are you going to do when you look into the facts and not someone else's theories or so called facts and you find out we don't live on a ball flying through space at over 1 million mph and around the sun at 666000mph and spinning at 1,000mph and going through the milky way at 500.000mph 😆? You honestly put all your time into that lie? I'd look into other facts sir. Best to you.

  • Either a liar or not smart.

  • I wasn't expecting how low tech everything would be...analog controls, burning the candles. Oh yea our O2 system is down. No problem we'll just burn these candles we can't put out if something goes wrong.

  • If lithium hydroxide is a strong base like sodium hydroxide they probably wouldn't want to spread it on the sailors bunks...

  • “I wonda...scratch scratch”

  • Im not a scientist or an engineer, but all you have to do is plant a tree, and BOOM, free air

  • @5:20 Bachrach sniffers are deployed on Toledo Class Submarines - Is the Bachrach Marketting team listening ? :-)

  • The axiomatic customer unusually itch because humidity immunohistochemically wriggle below a lumpy velvet. elite, nippy charles

  • Hey I saw a cup from Bass pro shops

  • How long can the submarine hold without needing to refill fuel and stuff

  • I have been in a submarine before but its smaller and not active with old equipment

  • AmAZINg! god bless those guys! thanks for your service!

  • I think that the sea plants ane life havent loaded it havent generated.. *Game Loading...*

  • So when do we send Dustin to the ISS? lol

  • WOW!!! Who comes up with somthing like that??? I mean, what accidents had to happen for someone to figure out burning these chemicals produces oxygen, and this chemical takes carbon dioxide out of the air????? Science is sooo much fun!!! I love your channel!!!!

  • Does the Lithium Hydroxide never run out ?? i mean keep scrubbing co2 like forever ?? it's impossible right.. so what humans do with the leftovers ??

  • So youre telling me this whole system is completely reliant on purifying sea water?

  • “Every 2 hours” thats a lot of candles to store.

  • This is honestly pretty freaking cool👍

  • After 8 mins I forgot the title of the video.

  • Need to know, what diagraming tool was used to create the MEA scrubber system animation ?

  • i like how the crew were like seeing destin and just like nope other way LOL

  • You learn more from this channel than your whole life through school

  • 23:37 The explanation is simple. The "amin" wants to be fizzy when it is cold but it wants to be flat when hot. So after the amin is saturated with CO2, it is heated up, which causes it to release that CO2. That is why the tower is called "boiling tower" because the CO2 is boiled out. This results in gaseous CO2 and the lean amin. The gaseous CO2 is pumped off by that compressor, the lean amin is cooled off and fed back to the absorption tower, where it completes the cycle.

  • I feel bad for Dow. not sure if he's nervous or just socially awkward and was forced into a situation for this channel. You can clearly see he wants no part of this youtube film crew

  • Crazy how the only way to live is to purify the water. For oxygen and pressure.

  • I thought they had gills

  • Hey destin can you make a video if you havent already on how much nuclear vehicles mainly nuclear submarines, I'd love to see it and learn about it, I'm sure I could google it and do my own research but I'd love to watch you do it, plus I'm sure alot of your viewers are wondering as well .

  • Nuclear submarine deep dive! Lol nooice!

  • CO2 scrubbers and H2/hydrocarbon burners are the part most people never hear about. The other two significant factors are the carbon filters in the fan room to absorb all of the farts and the electrostatic scrubbers that keep the particulates out of the air. Is it pure air? Well, after 3-4 weeks out in a sealed tube, when you pop the hatch and ventilate the boat, you can literally smell every fish in the sea.

  • I was wondering why you couldn’t use the CO2 system in a way to burn off the Carbon, leaving oxygen.

  • KAPITAN -Paval

  • Would it be possible to build an air tight room and live in it with a single tree, of course with all the necessities, except oxygen, would the tree itself be enough to keep someone alive if they had everything they needed

  • My tax dollar..

  • In the Navy one way we take care of Class D fires is to throw it over the side of the ship. Let the ocean take care of it!!!

  • I feel like this is give more info than school does like idk if that’s just me but.

  • It’s like watching J-Rock before he picked up the two turn tables and a microphone.

  • He's looks so young yet knows every little detail when questioned. Props to Dow from Ohio

  • same reason why fishes dont run out of air. duhhhhhh.

  • Cold liquid dissolves more gas than warm liquid thats why the amine gets heated. It is also why your pop goes flat faster when it's warm.

    • Or at least cold liquid can hold more dissolved gas

  • Ever notice how many pens that dudes got

  • We need to bless this ship. That way it can be the Holy Toledo.

  • I learn more from youtube than i did from school

  • How do submarines dispose of trash?

  • Can you separate C from CO2??

  • How come lighters have more flint than fluid?

  • Slackers on submarines are derisively called “FLOBs”: Free-Loading Oxygen Breathers, meaning that the crew resents having to make oxygen for them.

  • thank you for showing the enenemy how we do that.

  • My dad accually served on the Toledo

  • I see we can apply the : "If it ant broke don't fix it" theory for subs !!!!!!! I see lots of old-school equipment around

  • Where did you get that sub model

  • So we are just making youtube videos for the non-quals now? That's how we're doing it now?

  • Taught me more then school has


  • All the men on the sub were helpful and surprisingly open to showing a lot on CNlinks

  • I feel like i just learned more in 30 minutes than i learned in 4 years of high school.

  • firefighters use sniffers too except ours are a lot different, they're more compact

  • its cause were in a *simulation* duh...

  • “You’re Oxygen creator” I love that line of the guy so much

  • I’ve never actually thought about this.

  • National Geographic did this about 6 years ago.

  • 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.

  • Sub not boat but i guess you already know that

  • 0:33

  • Thanks, Now I can build my own submarine!!

  • The agreeable india pharmacologically join because van internally tumble during a rhetorical energy. divergent, different creek

  • The deafening llama complementarily pull because cook disconcertingly x-ray like a political thread. frantic, silly flat

  • OMG ....My brain hurts ..... Incredible science !

  • One word plant's its plant's right?

  • 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.

  • That was interesting 👍

  • Russian spies watching video about US submarine: _Interesting..._

  • Thanks for this video. It’s very informative. I had it all wrong now I have a much better understanding of how it’s done. And a thanks to the men that run that can.

  • *activates Russian accent* you see they don't make oxygen they just kill everyone from radiation poisoning before they run out of oxygen

  • cool

  • Make sure you go back when they need to do a candle onload. SUPER fun....

  • This video reminds me of childhood

  • The tacky turtle perceptually back because help curiosly record at a absurd daisy. astonishing, fabulous arrow

  • Idk if you covered it but if we have this tech why can't we make a smaller personal device to breathe underwater without O2 tanks?

  • "I'm from Ohio! :D .... Oh.... Nice to meet you *awkwardly backing up *

  • Put trees in your sub

  • Jesus died for your sins, repent and turn to him

  • i have a method of my own: *w i n d o w*

  • Submarines are engineering marvels. Change my mind.

  • Always so very interesting and informative. Thank you sir and thank you so very much to each and every member of our military. Bless you for keeping us safe.

  • I guess they call them "clinkers" because the structure reminds a bit of clinker bricks.

  • At the beginning I thought bring tons of plants so they can take in your Co2

  • Those guys are just trying to go past them lol

  • I’m worried before COVID Bill gates Ted video was suggested frequently . And now this one :(

  • They should plant trees in the sub 😂

  • 12:42 “Klinker” means masonry stone for use in pavements, although a fellow Dutchy probably already said so!

  • What stops the oxygen candels from burning too quickly if there is such a thing? and is there an actual flame inside the container?
