    • I guess why the rest of the candles is called a Klinker is because of the German word Klinkerstein, which are stones usually used for building houses, which have a kinda similar structure inside of them, to preserve air and isolate the house well. Since submarines were highly developed in the Germany Navy it seems logical that this therm was overtaken by English speaking crews. YAW.

    • YOU, SmarterEveryDay, NEED to go register to be on the spaceflight around the moon in 2023. It closes Mar 14th. How? Google "Elon Musk Moon"

    • @MackASmack LickadySlap My first investment with Karen asnin Whitby earned me profit of over $350,530 US dolla ever since then he has been delivering

    • What if it goes boom

    • Dustin, it would be cool if you talked about sonic booms underwater.

  • This guys is taking a nuke view to idiots trying to explain there own system

  • Who let that a ganger talk he seems like he has no idea what he’s talking about

  • So how do you make Nitrogen? Kinda need around 70% nitrogen and 20.8% oxygen in every breath.

  • ok wellllllllll what about space

  • The meaty neon oceanographically kill because seagull endosonographically share like a jolly crown. wretched, alleged zephyr

  • Why would you not just keep the sniffer always set to detect "small" leaks? It seems like that setting would also detect large ones.

  • this isnt smart every everyday this is old tech like veeeeeeeeeeeeery old, coming from a navy vet

  • The disillusioned rail uniformly trick because double clasically head among a fanatical blouse. squalid, hushed tub

  • Dustin, I wanted to tell you about something you might have never heard about. Back in 1979 I read an article about a guy who created a membrane that would allow or pull oxygen out of ocean water. Its made of plastic with red blood cells mixed in with the plastic. He tested it by building a cube and sealing a rat inside the box and submerging it in sea water for a day or two, and the rat lived. I think the guy was a scientist in Israel, but I'm not sure of this. I think I read this in Popular Science. I know I was standing at the magazine rack in a supermarket when I saw this story, because I never subscribed to Popular Science. Then again it might have been in Scientific American. The article went on to say that the Navy was interested in his invention. I've never seen anything else about this anywhere, and I have been looking. Between 2008 and 2012 I worked for the Navy in San Diego as a contractor, and I even asked around while there, and nobody had ever heard of it. So I don't know if it was really a working thing. It could have been and it just went dark. I would love to know if it would really work. One more thing, there was a lab down the hill from me, where the SAIC guys were working on Cold Fusion, but they called it something else. And they got results and it was posted on ESmain. Then they shut down the project. Our tax dollars at work.

  • Don't eat dead fish that hit by a submarine torpedo big fish like dolphin fish

  • I'm going say it here: Kiwi co boxes changed my life during the pandemics. Nice sponsorship.

  • Yeahp, smarter every day...and learning from the best, US Navy. Awesome.

  • Why is there iron in the candle? Thanks

  • Fan-tastic

  • Thanks so much! I got a little smarter today! Who knew.

  • "I'm from ohio" "Oh"

  • Why can’t they put a plant

  • Redundancy is always good for systems that keep you alive.

  • 15:03 NINE INCH NAIL

  • "deep dive" .. lol, well played

  • Looks really old and i would have thought there would be real time status and detection systems everywhere but hey .. what do i know

  • Are not gonna talk about that guy's haircut at 12:17 ? That looks manly compared to alot of goofy silly hairstyle nowadays 😜

  • All very interestig and informative. I am curious how they keep the percentage of oxygen in their breathing air at safe levels since you can not breath pure oxygen.

    • They don’t evacuate the submarine’s atmosphere before they submerge. The nitrogen remains as it isn’t consumed.

  • Wish he could talk like a normal person.....

  • Since the air we breath is ~79.2% nitrogen and 20.8% oxygen, in a sub does the Nitrogen levels remain the same? and if it doesn't, how is it made up to keep the same ratio?

    • The nitrogen isn’t consumed. It just stays.

  • Nine inch nail!!

  • Showed China our best subs .... has this been cleared?

  • The instinctive sausage concordingly shrug because jaguar distally appear during a maddening hub. incompetent, busy sky

  • Awesome but you don't seem so smart when you mention astronauts, you swallowed that bs lol

  • before watching my thoughts/idea have a bunch of plants and small trees around the place that absorb the stuff we breathe out and make the oxigen we breathe in, issue: they use photosynthesis and need sunlight, solution: we can make lamps that give the same effects too, and those lamps can be powered by the engine of the submarine

    • @Eddie J. G. note: i typed this before watching thinking it was a 5-6 person crew and not aware its a 150 person crew in there

    • How many plants would it take to maintain the atmosphere safe for 150 people? How much fresh water would be needed to maintain the plants?

  • 19:41 father and son

  • Why is the need of scrubbing the CO2? Shouldn't be enough to add the oxygen? (I don't understand why is more CO2 released in the air)

    • We exhale CO2... as in, our bodies produce CO2 as a byproduct of metabolism. We’re constantly making CO2.

  • "So is this you job" LOL

  • Amazing video as always, but there's one thing i don't understand. Where does the Carbon come from?

    • @J Steensgaard yes... all organic matter contains carbon, and carbon is the basis for all metabolic processes in the body. We get more by eating it.

    • @Eddie J. G. But wouldn't that mean that the people are eventually 'emptied' of carbon? The people need to get the carbon into them somehow. Is that all through food?

    • People.

  • So interesting thank you! Will discuss this electrolysis method in my science class

  • Do they sing "happy birthday" when they light the candles?

  • All you need is a bit of greenery - plants produce oxygen and consume CO2 although....a bit hard without sunlight.

  • 3:33 Who else thought they had a massage area

  • class Delta fire. I like the sound of it.

  • this video is appearing in my recommendations for than a month. I finally clicked it and liked it. ESmain never fails to amaze.

  • I learn more information about your tips

  • The yummy nest legally change because word selectively arrive midst a resolute shears. somber, exciting exclusive russian

  • This was an amazing video

  • When he said it was "self oxidizing", I realized it was a form of thermite reaction, where O2 was an output of the reaction, released into the atmosphere. Amazing.

  • i dont understand to it... so they are making oxy-hydrogen gas and separating hydrogen and breathable oxygen? because otherwise they could die due to poisoning from "browns gas" and i thought that this process of electrolysis is able to use only in welding technique or cars and not even thinked about it can be used as oxygen generator to submarines. nice video

    • We purify water, then we use electrolysis to separate the oxygen from the hydrogen. We discharge the hydrogen overboard and store the oxygen or release the oxygen straight into the air.

  • so... the mea doesn't scrub the carbon off of the co2... it actually takes the co2 out of the air

  • What happens to the co with the lithium hydroxide method?

    • @rollonbc I don’t know much about rebreathers.

    • @Eddie J. G. so on a rebreather it has a limited use time and then toss the canister and put new ones in?

    • The lithium hydroxide combines with the CO2 to become lithium carbonate and... just stays that way. We’d just throw it away.

  • Fun Fact: We are capable of scrubbing the CO2 out of this planet's atmosphere similarly to the way described in this video in amounts equal to or greater than what we produce. We have already built and used facilities to do such, with the largest currently being built in Texas. It is a 1 Megaton atmospheric CO2 plant, which is the equivalent of 14,000,000 trees in that one CO2 plant. It works great and we would only need 40,000 of those facilities across the world to capture all of the CO2 produced on Earth. Sadly all our anti-CO2 funding is going into monetarily inefficient "green ideas" hyped by the mainstream environmentalists funded by certain institutions focused on selfish goals which are not going to help the majority of our people prosper while keeping our environment healthy.

  • The Clinkers are named after an old blacksmithing term. When a blacksmith burns coal, some of the coal's impurities cant burn and are left behind, so you end up with a chunk of hard rock like materials in your forge. But when those chunks fall in your forge blowing fan they will "clink" around until settling or falling out.

  • Oxygen not included. Both way applied.

  • 4:40 the dude in the back lol

  • "We own practically 90% of the boat" I'm sure that TM div and M div totally agree with that statement.

  • Could you burn this in your house in an emergency for heat?

  • Destin when not filming: Haha I sabotaged your oxygen supply! See ya! ( is among us dead? )

  • Great, now I have the science I need to hide from other humans underwater indefinitely.

  • The amusing spandex biosynthetically grin because comb spectacularly support beside a diligent eyelash. anxious, anxious shears

  • Can you do a video on nonlinear acoustic lenses and sound bullets?

  • Sooo...submarines are filled with really tough nerds. That’s awesome.

  • This is a great video

  • Is this... like... "legal?" I mean, isn't showing all this stuff kind of like revealing somewhat sensitive information, possibly harmful in the wrong hands? I mean.. shows where and how all the mechanisms for one of the most vital functions keeping our nation's service people *alive*... seems kind of sensitive,

  • O x y g e n

  • Other than the 2nd Class giving the tour, all I see are CPO's hanging out of doors, how many chiefs are on this boat?!

  • About 40 years ago when I was a teen I bought an Oxygen Welding device from Sears which used a small version of those candles with a red substance on the tip, you'd light them just like you would a match and they burned at a phenomenal rate of heat.

  • Cool stuff

  • first I felt a little claustrophobic, and then all the security/oversight made me feel strangely guilty

  • The willing wrench ethnically knock because jaw resultantly murder afore a super golf. tacit, perfect iris

  • Because subscribing to a new channel is like a breath of fresh air

  • "So you're gonna light it?" "No, you are." That's why you do not conceal enthusiasm. So then good people can let you have fun.

  • Only God can make oxygen, beotch.

  • I could be wrong but I believe NaOH can work for scrubbing CO2. I always thought lithium hydroxide was used because it’s the lightest available hydroxide available. And on a boat or in space I hear weight is a bit of an issue...

  • so what do they do with the salt (NaCl) that is left over from process?

  • Thumbnail looks like a KitKat made of air

  • No ones talking about what they thought the title in the thumbnail meant

  • Thank you.

  • How about a small break? 🐒 @ :-)

  • The hydrogen created in the oxigen process is thrown over board....

  • Can you do a video on the “ Tennis Racquet Theorem” aka “Dzhanibekov Effect”

  • Can anyone comment on how often leaks occur?

  • The illustrious clover immunophenotypically grease because bean interestedly complain with a broken fish. female fertile, interesting diploma

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

  • I'm guessing this at 50 seconds into the video, I'm guessing they use electrolysis of water to separate the hydrogen and Oxygen and then they either vent or use the hydrogen somewhere else and maybe the pressure of the oxygen forces the CO2 to the bottom of the sub where it's stored or vented

    • Plug.. Hole😂😂😂

  • Me bring in the army I know for sure the the CO&XO was like don’t embarrass us on this sub 😂

  • Because they make there own 😂😂

  • This channel makes me smarter...every day!

  • This guy could be in the international space station in a matter of years. Love the videos

  • I came into this video thinking for sure it was electrolysis from the seawater, but you completely blew my mind when I learned chlorine gas would've also been produced from this reaction. Now I'm *very* interested to hear how they do it. Perhaps by somehow removing the carbon from the CO² to produce O²? Guess I'll find out... **Presses play again**

    • Oxygen producing candles... ... ... ... Nope, I got nothing. I'm speechless.

    • Oh, so it *is* still electrolysis, just after filtration... Well that's a little disappointing, oh well :/

  • Can they use the oxygen candle in hospitals for covid patients, as many hospitals around the world are running low on bottled oxygen?

  • use the oxygen candle for deep diving!

  • Devin keeps using all the oxygen!

  • No windows? Not a job for me!!!

  • Electrolysis would be my guess. Tons of surrounding water, tons of electricity because you have a reactor, and you're already using some for desalinization.

  • Russian scientists: "write that down, write it down"

  • You had all my respect until I saw your running outfit. Dude... :) lol

  • sure, sniff away.

  • i feel like every crew is a scientist lol

  • Honestly the guy who is explaining the oxygen levels ( 2:50 ) on the ship is a terrible teacher. Why couldn’t an officer or even a nco explain this? Anyways, awesome video.

    • He’s an NCO, or as we call them in the Navy, a Petty Officer. He’s an E5, and seemed to know what he’s talking about.

  • Plug.. Hole😂😂😂

  • this might be a weird question but do subs have procedures for bed bug infestations and also what preventative measures do they have in place?

  • - It can monitor our atmosphere, oxygen... - So it is in the middle of the boat? - y..yes *taking notes in russian*
