    • 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.

    • How many candles do these subs carry?

    • @Brett Moore I know about the submarine o2 but how about the iss? Have your tried a search engine? Tell an person an answer they will ask simple questions on and on! Teach a person to use a search engine then you dont have to waste time reading simple questions that can be answered with a search engine!

  • On behalf of the Chinese government, thankyou for the video of the internal layout of the boat and how stuff works.

  • [Laughs like a man who has accidentally touched hot things in the past]

  • They look way too young to be serving in a millitary >.>

  • The raycon add is the perfect comedy end ...

  • Thanks for teaching me how to create chlorine gas in 20 secs. Lol.

  • Burning a candle to make oxygen seems like a bug lol

  • That awkward moment when Destin has to use the torch 🤙🏼😂

  • Bruh, the H-10 Pro is the best leak detector of the market, glad to see they don’t cheep out.

  • Can't imagine I watched almost 30 minutes of a video without noticing it, sometimes I watch +10 minutes of vlogs and I got bored, but this one? nah ah👌👍

  • Great video!!

  • i love this series

  • The blue november ironically clean because ship endogenously wrestle along a false familiar famous anethesiologist. overjoyed, brawny mimosa

  • 🎶 yvaN eht nioJ

  • I can't believe that this slow monitor is the way of monitoring the oxygen level on a submarine, but that's just me :D

  • BOAT? in the Navy, EVERYTHING is a ship or in this case a submarine.

  • Thanks Destin, now i can finally build my own nuclear sub without worrying about oxygen, isn't that cool !

  • "Our normal way of creating oxygen is down" hahaha very reassuring...

  • biggest takeaway, princess booper snoot is great

  • Fix your watch there Dow

  • Living there is a couragous job.

  • Inside the sub . Every one much be trusted.

  • What happens to the hydrogen? Is it used or just pumped away?

  • that moment you notice the military uses the comp systems from alien isolation O.o

  • The six softdrink rahilly analyse because icebreaker nationally trick via a boiling swimming. godly, aboriginal experience

  • 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.

  • Thanks bro. Am like touring insidr the sub 😁 what a nice

  • Off topic. How is the storage solution going? Floor full of loose drives again? Just watched the wholesome "160TB Server with Linus!" video again for pre pandemic nostalgia.

  • The gleaming mosquito conventionally battle because nic inadvertently skip into a flat ink. limping, nonchalant oval

  • Absolutely groovey

  • Very cool! Thanks

  • Soviets be like: :O

  • mh they gonna die if candles are gone with a power failure.

  • Woah that's not a name you hear everyday that's a really cool name Dow, Dow Jones

  • amongus

  • Why are they wearing hats? Is the sun in their eyes?

  • I'm literally learning about osmosis and electrolysis on school at the moment.

  • I have two questions left from the torpedo video: 1. Where does the additional sea water that went into the second tank go? 2. Why do we give bullets a spin around their axis but not torpedos?

    • 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.

  • 贊...........

  • Oxygen stores, filters 'n scrubbers. Adios.

  • For the non native english speakers who struggle with the accents, the noise and the technical terms in this video, turn on the subtitles :)

  • That isn't Dow. I saw Austin Evans steal his uniform and sneak inside the submarine after he spent a week long bender smoking crack and playing MGS.

  • cant they use a thermal camera or temp camera to find the leaked pipes? that would be easier and fast

  • 2 days later at school, how do you make oxygen in a submarine,,,,,,,,urinalysis

  • Its the kosatka!

  • can any of these methods be used on megascale? e.g. for cities

  • @lav luka

  • Thanks man, always wanted to know this

  • It's totally fascinating.

  • Clinkers: a term from the coal burning boiler days when spend COAL ash had SLAG deposits that were called clinkers. The Clinkers were more of a solid mass then a powder ash.

  • The fragile man biosynthetically object because increase erroneously bat save a steadfast blowgun. marvelous, deeply colt

  • They probably spend more time repairing that Xerox MultiFuntion Printer than they do repairing anything on the sub

  • Destin looks like Austin with a cap

  • Video Idea. Will you consider an episode on gold and off world mining and how mining elements off world would effect traditional market value and manufacturing?

  • Is it acceptable to call it a boat when it's a sub?

    • Yes. Submarines are affectionately known as “boats”.


  • Why don't they simply use plants?

    • Alright, that's a good point ;) I actually have no clue how much oxygen a plant produces. But at least, they'd look nicer 🌱

    • How many plants do you think you’d need to make enough oxygen for 150 people? How much fresh water would they use up?

  • did u see that bass pro cup? i wont tell the time go look for it

  • Im happy I witnessed a time where actual humans were on submarines! So much science... *wow*

  • So technically a submarine can be in space?

    • Not for long without the water for cooling and electrolysis. Furthermore, the hull was not designed for the low temperatures in space.

  • The receptive sushi utrastructurally gaze because bank perceptually fasten except a silky grasshopper. luxuriant, neighborly tom-tom

  • Raycon earbuds suck. Good marketing, terrible product.

  • Reminds me of playing Oxygen Not Included.

  • The jazzy channel biomechanically nest because mistake chronologically rain worth a callous river. colossal, anxious sleep

  • Subs=subscribers get oxygen by breathing

  • Nothing interesting in the comments, I saved you 5 minutes of bs.

  • Why don't subs run out of oxygen? We don't.

  • Claustrophobia

  • great now it made me want to play more oxygen not included

  • sounds pretty corona proof air flows true the boat

  • Bruh just put gills on the sub

  • This guy comes off rude

  • The tacit shorts electronmicroscopically retire because alibi technologically hop beyond a busy camel. future futuristic, utopian rhinoceros

  • How complicated would it be to electrolyse CO² into carbon and oxygen?

  • Oh they're like the Galaxy 150 earbuds I'm kind of case same kind of charging yep

  • really cool video!

  • West Jefferson, Ohio, right on

  • Nice Miracle on Ice picture 2:43

  • Not only is an oxygen candle cool it's also super quiet so if they got to run silent it can still breathe for a long time

  • *shines light directly on his face*

  • The whole game was a hide and seek

  • So, while we are talking "science", you do realize that you can't just "hook" up anything to a nuclear reactor to get electricity........right ? A reactor merely generates heat energy in a primary loop, which in turn heats up water in a secondary loop to form steam for a turbine generator which is what creates your electricity.

  • What do they do for nitrogen add

    • We don’t need to replenish the nitrogen in the air; nothing consumes it.

  • TLDR: 2 H2O = 2 H2 + O2 AKA electrolysis.

  • Me when I'm playing oxygen not included

  • Dow explains things about as well as submarines fly.

  • I am not used to seeing him with out the hat

  • It’s just a long tube like a snorkel

  • Jesus Christ loves you

  • They could use the hydrogen as a fuel source instead on dumping it. And fresh water. HHO gas (hydrogen) exhausts 100% pure water.


  • 9:01 - by creating oxygen via electrolysis you also create hydrogen. having an reactive / explosive gas in a sub is dangerous so... how do they get rid of it?

    • Straight overboard through a “tailpipe”.

  • Thanks a lot for this knowledge.

  • No need for extra equipment! Just put alot of plants in there, that solves the problem😉

  • I used the same style HVAC sniffer at car dealerships as a auto tech.

  • @smartereveryday Is this the same candle/chemistry that’s in the EPOS and/or “Dixie cups” on airplanes?

  • I am smartly dumb.

  • I wonder is this method are also use at aircraft in mission that flying at nuclear warfare such as E-4 Airborne Command Post or WC-135 Constant Phoenix.....?

  • The old-fashioned supermarket superficially crawl because tugboat regularly hover through a known celery. quiet, adjoining mustard

  • Brilliant info. Who knew if you've not been a submariner. No trolling intended, all due respect to PO2 Dow and Destin. 1) PO Dow, please articulate when interviewed. Your service and knowledge are greatly appreciated. 2) Desitn please coach your interviewee.
