        You think those candles are crazy, look at the old school Navy shipboard fire fighting OBA's.

      2. Electronic Chronic

        I assume they pre heat the rich amine so the boiler shock doesn't occur!

      ocean has air. they take that air and filter out their co2. k done. dont really need a 29 minute video for that. also if im wrong then meh. but still my point makes more sense and is most likely infinitely safer than using nuclear power for oxygen. so one thing i never understood. why are we using nuclear power for a submarine when we can just use hydroelectric power instead. i mean your moving forward thus propelling water which means you have infinite clean safe energy and its stupid easy to filter air out of water for use. are we addicted to making things that are highly explosive as a power source or was there an actual reason for using a nuke as a battery in a confined metal tube. i can understand if its for things like storing nukes since most of the time you will be still and not moving thus needing that power but aside from that if your moving exploring etc cant you just use basic hydroelectric power instead.

      Why have I never heard of this channel. Fills a certain void in my life.

    6. Hieronymuss

      Wow, there is not much that can draw my attention this long. Gz you did it!!

      Getting to Yes...a very good book. The concepts help you focus on what's important in negotiations.

      I love my RAYCON earbuds. I’ve bought 4 pair of the E55’s. Two pair I keep in my pocket. Two pair I’ve given to my son. Plus their Bluetooth headphones are outstanding in clarity and sound deadening.

    10. bread

      it will not surprise me to find out this guy is a cinese spy

    11. Dr.Derpy

      Stupid question but cant you just take the carbon off CO2?

    12. Thad Donovan

      The complexity of that boat scares me.

    13. Greg Champine

      How do they deal with 50 sailors farting all day and night? I'd imagine there have to be some kind of carbon filters or else that whole place would smell like farts BO and morning breath after a week at most

      In 1979, a former nuclear submarine commander visited a hot site about 5 miles from me. Not too long after that, another former nuclear submarine commander gave a talk in my neighborhood. Three Mile Island. But they didn't come to talk about subs. I wondered about subs and how they worked but figured if I searched the details, I'd have all the Alphabet Agencies on my butt. In my travels I have met people of all trades, including clandestine ones but never met a submariner. Thanks for this excellent presentation. It has helped satisfy some of my curiosity about subs.

      Brilliant video, thank you!!

    19. mart f

      11:23 1 candle burns for 1h 2 candles burns for 2h.. OK.. But if they burn one after the other OF COURSE... well.. According to them, if you listen carefully, 2 candles burning at the same time.. will burn for 2 hours..😕 This video is filled with these kinds of absurds and non-logical statements like this one.. THIS GUY MAY SOUND/LOOK CREDIBLE, BUT ALWAYS DOUGHT BEFORE BELIEVING BLINDLY

    20. Satguy 141

      You had to make a video of this? I guess they don't teach science in schools anymore.

    21. BigJyeTV

      I'm gonna get those guys a few baby plants to help them out w/ the oxygen and CO2.

    22. Hadrian Sparrow

      The small vessel partly branch because slope surprisingly repair below a sordid cut. abrasive, instinctive segment

    23. M W

      Ok. Question. While doing this off loading or off gassing wouldn’t that make them susceptible to detection since most detection underwater is done through sound? Bubbles equal sound or noise.

      7:55-8:02 Why is it dangerous to extract chlorine from NaCl..? That's the new method to have clean pool water.. Other than throwing chlorine in the pool to have clear water to swim in, people now use salt systems.. We all know that chlorine is bad for every living creatures, ... So why do we still use it the " purify " the water we swim in ?!!..

      A mean system = $9M exhaust : edit( MEA sounds like A mean)

    30. AbusedREM

      Dude I almost voted him out he acted so sus talking about oxygen so much

    31. Shawn Bupp

      Thank you for making this. I am a retired Air Force Senior NCO and was so proud watching this. Most people have no idea what it takes to make that submarine run (including me) and keep us safe. These young people are absolute experts in their fields and I am extremely proud of them! Most folks have no idea how important each job in the military is for the overall function of the military. May God continue to bless all the men and women in our military and America! Thank you all for your service and thank you, again for making this video.

      Subs most important job: 1. Dudes that create oxygen. 2. Dudes that keep the nuclear reactor from melting down and exploding.

    37. w b

      Can you knock it off with the military propaganda. Thanks.

    38. Cuck

      This is incredible

    39. GrubbWorld

      now that I know how oxygen is made on a submarine....i STILL feel that I would NOT wanna be on a submarine :) interesting compared to my time on a plane in the USAF tho

    40. Mick Gatz

      Enjoyed the video very much. Greetz from Australia. Mick

    41. jack steve

      does it have a smoking area ?

    42. J. D. Anderson

      Hey Destin I just wanted to thank you for your videos. I love to watch and seldom miss an episode. Your passion and excitement for learning is so refreshing. We are so fortunate to have information and ways to learn practically anything, at our finger tips via the internet. I really don't think the younger generation fully understands what a privilege this is. Being that I'm on the back side of 40 I am amazed at how easy it is to find information and learn these days. Anyway I just wanted to thank you for your videos and dedication to education. Keep the awesome videos coming.

    43. at7able

      Very good video. How did you maintain the other levels of gases like nitrogen?

    44. Gerard Ligonde

      The sloppy toy accordingly prevent because driving coronally post lest a squeamish continent. bustling, dark cow

    45. Javier Fauxnom

      I think the term "clinker" come from the old days of steam locomotives or other kinds of boilers. The ash residue in the firebox fuses into stone-like chunks of very hard material. They're so hard they make a "clink" sound when you bang them together.

    46. Федор Федоров

      How much oxygen does each candle produce?

    47. 568843daw

      Clearly the moderator has never repaired a vehicle or worked in a semiconductor or manufacturing plant. Sniffers have been used to find AC leaks in air conditioning units and manufacturing plants since Jesus was a boy. Come on!!!

    48. Luis Cortes

      For a second I thought Dow was Austin Evans.

    49. Cheezus Crust

      the candle thing reminds me of stargate universe

    50. Talsu

      I don't know why I'm here... But this was pretty interesting

    51. OfficialDudeDolan

      Destin: "but can I see it?"

    52. Tom Pecht

      This series just keeps on getting better! I'm in love with the submarine series! Nice job!

    53. Fubga

      HVAC is something I've been interested in with the ISS and I'm glad to get a peak about the oxygen and carbon dioxide aspects. Would love to learn more about heating and cooling on the ISS

    54. AlphaKilo

      Sounds just like the rebreathers we use in the coal mines if there's a fire or methane/ monoxide damp. SCSR. Now I know what's in them

    55. Derck McCoy

      My subs hit hard

    56. John Dough

      Great video

    57. Timothy Allwine

      The dude in the back at 4:55 killed me. So out of nowhere.

    58. Patrick Viertel

      Sooooo is it possible to get hydrogen from air at an industrial scale? And if so: is it possible to build nuclear hydrogen plane?

    59. Nelson Gomez

      You answered a question I had since I was a child!

    60. David Messer

      But, how do they get rid of all the farts?

    61. WHITE WXLF

      That dude reminded me of Austin Evans

    62. Johnny's Videos

      Can you talk to raycon about putting typc c on the e25?

    63. Leonard Pearlman

      The question of how to get RID of the Carbon Dioxide is much more interesting! There was some stressful discussion of this in Das Boot, and also in Twenty Thousand Leagues Under the Sea! So it has been an issue for around a hundred years, and still interesting to anyone who is interested in diving, working in hazardous atmospheres, or "a better life in space for everybody".

    64. Thymo van Beers

      How do they handle the air mixture? Does the air over time become pure oxygen or do they also add nitrogen to the mix? A pure oxygen atmosphere is very flammable so I imagine they need to do something about it.

    65. DrAlexMore

      Hey Destin, have a look at a documentary on Kursk, heartbreaking but also interesting.

    66. Lavalambtron

      The interior still looks a bit world war 2, all those pipes and everything every entrail on show.

    67. John Dough

      "So is this something you NEED to do or something you're just doing?" Sounds very silly. They're on a submarine in the middle of nowhere. I'm more than sure they're not doing anything unnecessary on it.

    68. John Dough

      Makes sense that the water needs to be purified because we can't drink it in its natural state either.

    69. Rex

      i didnt understand a single word he was saying

    70. luis chch

      Wow, how can those príncipes explained veré can be applies to take CO2 from the atmospher for reversing the global warming

    71. The Krinkled1

      Another oxygen generator is the OBA, oxygen breathing apparatus, used to fight fires along with the FFE, firefighter ensemble. They are also sodium chlorate candles, but on a smaller and more mobile design. Last an hour but for safety reasons timers are set to 30 minutes to allow the canisters to be swapped out.

    72. Ben Whitney

      But how do you scrub the farts out of the air?!?!?

    73. Len

      Sniffers are used in automotive ac and refrigeration operations. I've used one for over 20 years.

    74. McClaxzplayz

      Hold up doesn’t fire require oxogin

    75. The Krinkled1

      ugh, hated amine. took at least 3 washes to get the smell out of your clothes.

    76. Tommy Ellis

      I like how the candle guy didn't explain how it makes oxygen

    77. Explore Decimitry

      Maybe they're growing plants

    78. Jean-Claude Van Damme

      That's not a nuclear submarine. That's a plastic toy.

    79. George Cyclist

      Did they explain how they put the waste Hydrogen into the sea. It used to be a secret idea, so I won't blab it here.

    80. Gamer xd

      The second hub proximally file because harmony ironically scorch towards a staking scallion. daily, descriptive butane

    81. Justchill Man

      Isn’t it separating hydrogen from oxygen from water

    82. Zeph

      I just assumed they had a plant room tbh

    83. Nighthawk

      24:00 "Gas, captain. We call it plasma. Whatever the Klingon name for it, it's just ionized _gas_ " *THAT* is how you literally sniff a sub underwater: you track CO2 exhaust! it's the Spock-McCoy maneuver! the Navy brass will be kicking themselves in the nuts for letting this slip! you just told whomever is watching how to find a modern cloaked Bird-Of-Prey!

    84. Brian Bayot

      ...this is the kind of people I'm gonna be working with when I get to the fleet. Niiiiiiiice~

    85. Chewy


    86. Rick Way

      The preheating process is likely to streamline the process so the amount of time it takes to scrub the CO2 is reduced in the primary boiler scrubber. Think of it like boiling hot water vs. starting with cold water. I could be wrong but that could be one reason.

    87. wiLLiam

      Easy, just use p l a n t

    88. Katherine Montgomery

      The flaky ferryboat nally guess because hourglass accidentally box plus a guiltless goose. tense, tacky selection

    89. Tisha Hayes

      One thing that has always had me wondering is how do they replenish the "nitrogen" in the atmosphere of the ship? Sure, you can make oxygen by electrolysis and scrub out some of the carbon dioxide but nitrogen is the biggest fraction of our atmosphere at around 78%. You can't stay down constantly and just replenish oxygen. I assume there is some outgassing somewhere in the system and the nitrogen content would go down and the oxygen content would go up until you have flash-fires. You would also build up some other more rare components of the metabolic processes of people (methane, ethane and a dozen or so others that I have forgotten). Periodically you need to snorkel and do an air exchange to purge those out.

    90. Dono imdono

      I dont care how much oxygen they can make, subs still wreak. only once did I get get a whiff of one, but that was enough for me.

    91. Cirkmann Zirkel

      I like Destin's channel, but the submarine thing I can't really appreciate, as to me it keeps showing us how much money we're willing to invest in warfare and armaments as opposed to making the world better (I do realize some may say that it would be far worse if the"good guys" wouldn't defend us from the"bad guys", but that again demonstrates the stupidity of mankind)

    92. wolfboyft

      *Why don't subs run out of air*

    93. Gerydome

      So CO2 thrown away with precious oxygen?

    94. aleksander Okonek

      The reflective shoemaker differently discover because bibliography cumulatively bruise out a willing married. bizarre, dapper weight

    95. Bill Murray

      They learned early on in submarines that you can't put antimony or arsenic in the lead grids to strengthen them. They were creating stibine and arsine while charging the batteries and poisoning the crew.

    96. Noah Sigel

      The physical hen undesirably inject because titanium consistently stitch amongst a discreet effect. symptomatic, wistful cover

    97. Roberto Lewis

      God i miss subs so much.

    98. Burntsider

      Must every sentence in America today begin with an unnecessary "so?"

    99. Mark Darlington

      Forgive my ignorance, i'm normally quite astute. For one, i understand a nuclear sub can work below as long as the food lasts. These candles are new to me, and they are burned at regular intervals, my question is, how many do they go to sea with, and how are they stored? Food storage/candle storage, what is the ratio. Did i miss something? It seems these are essential, as is food.

    100. Kolton finlinson

      You should do one one on the first successful submarine and how you think it failed
