        @SmarterEveryDay hello I love your vids

      2. Corey Jenson

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

      3. Electronic Chronic

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

      4. RobertMStahl

        Micro balance equations R different from macro. Only a difference makes a difference, bud. I got nuttin out of the scale of materials needed, per person, 4 eXample.

      5. StabbyJoe135

        How to consistently beat the ever changing algorithm? Avoid the algorithm. Genius (every day).

    2. BoltGoesPro

      check enacfire fam ive used em for years, water proof, and better and only $35 lmao

      Cool! So the only consumables we need to breathe outside of Earth's atmosphere, besides equipment, are water and electricity/energy. Water can give us oxygen and hydrogen (which can be used as fuel to generate more power), MEA equipment can continuously remove carbon dioxide as long as it's powered. And there are unpowered chemical backups that can be held in storage for emergencies or if machines break down and need repairs. Add nutrients for plant life that can be recycled from waste, and you'll also have the basic materials needed to farm crops and live indefinitely if you have the right equipment and can maintain it. With these clever technologies, with common basic elements consumed by the right machines humanity could settle outer space! Water is abundant and so are sources of energy: nuclear, solar, and often heat and wind. Submarines are pioneering artificial atmosphere technology!

    7. See Saw

      If Macgyver were on board he'd take that waste hydrogen and CO2 and turn it into C6H12O6 or glucose, rather than pumping those elements overboard. Nothing gets wasted.

    8. Bidens Harris

      If you dislike this I will take your job “Biden’s harrissss the 2nd

    9. Barton Archuleta

      It’s not impossible for submarines to surface under the ice. Submarines pretty regularly break through the ice

    10. Nimbus Shadow-Wings

      wonder what they do with the spent candles

    11. Ping Pong

      Is that not all classified? Some soldier was jailed for taking one photo.

    12. R Mitchell

      Great video

    13. Based God

      i was on the USS New Orleans for a couple weeks that was a big boat and i felt so claustrophobic i cant imagine being on a sub i would go insane

    14. mEdnAzz (mijkolsmith)

      That was very educational thanks

    15. Versatile Faerie

      "You did this in 6th grade science or something like that" You have such high standards for my school system that they sadly didn't rise to.

    16. Tontowi Prasetyo

      Cheaper alternative: bring plants

    17. Ron Ngyen

      Creepy robot reflection at 3:52 in the background. Looks like the robot from Zathura.

    18. Chase

      I love how he introduced the dog and not the human attached to the dog.

    19. Elektrokinesis

      imagine shooting all this video on a submarine and waiting months for the government to clear this dude to upload video

    20. Finn Cashman

      Bruh how did you get on a nuclear submarine in the first place? Like how, can do it idk

    21. Michael Lawlor

      So I'm doing a school project on how to control CO2 emissions and I can't tell you how much this helped. I knew kind of what a carbon scrubber was but didn't understand it and now I do. Thanks a bunch!

    22. E Lye

      You seem to do a lot on submarines. Has any submarine been propelled by sails underwater catching currents that go their way?

    23. Silvex _YT

      4:56 we not gonna talk about him lol

    24. J Perez

      the only primitive science in the submarine is the use the English system of units. omg

    25. Anthony Martin

      Im guessing these Oxygen Candles are similar to how the emergency oxygen is made on Aircraft.

    26. MegadethTillDeth

      Thank God for these people.

    27. Jon Rayner

      What other by-products does the oxygen candle produce? Just oxy? If more, what happens to the other?

    28. Joseph Milford

      You know what I'd like to see? A room full of the 1.1k people who downvoted this. I'm just so curious what it'd look like.

    29. John Princler

      Destin, you never disappoint.

    30. Danny Chariot

      anyone else reading the subtitles? "laughs like a man who has accidentally touched hot things in the past" omg XD

    31. no ka

      Is it because they are filming youtube video? I just noticed the guy explaining the candles has a nice hair

    32. Jay Corrales

      How are they letting you view and record this information about a classified military vessel, and why are you posting this on YT?

    33. Michael O'Brien

      I thought Dow said that they used the pressure of the depth to push the CO2 out. But the pressure would seem to keep it in.

    34. Arthur Moorhead

      why does this feel like the mythbusters?

    35. cat -.-

      All I can think of watching this video is pink sus

    36. Gaius van Baelsar

      kewl! sub oxygen candles are actually really big hot hands

    37. Spencer Smith

      Hey destin I have a video idea for you... I think you should do a video of how a radar gun works. I was just thinking so maybe people will agree please think about the idea and I will keep looking on you channel. Thanks!

    38. Michael B. Titman

      I’m curious at how the first iterations of submarines found solutions to these problems.

    39. jeremy dutton

      Yoooooooo i went to high school with Dows wife small world lol

    40. Lea Tex

      I supose there are some other details, because air contains just 21% of oxigen. We breath air (a mix of gasses) not only O2. Pure O2 is toxic for humans. Sure there may be some procedure to get pure air with the correct mix. It's much more than oxigen. I imagine a submarine as a big SCUBA diving aire tank. Anyway, great video like all others! Thanks for sharing.

    41. Linux Ninja

      A bit of advice: Learn the Navy ratings. And don't call the Petty Officers "Sir". Knowing which ratings are doing which job is informative.

    42. William Jemeyson

      “Where you from?” “Ohio” “Oh...”

    43. Big Dawg

      SmartEveryDay is Russian spy. Mission accomplished

    44. sammy_1_1

      Good thing he didnt sabotage O2...(for legal reasons, that's a joke)

    45. denysost

      Hmmm. Isn’t this like... classified? 🤨😅

    46. Joshua Keough

      Use plants very good source of o2 and takes co2

    47. Zash Masters

      Who is at CAMS? Cyan is sus.

    48. André Graça

      I can't understand a lot of what that Dow dude is saying :/

    49. Antonio Castro

      But if you burn 24 candles in a day, I guess you don't have much storage room in a Sub for candles so how many days can you stay submerged....

    50. vipul chauhan

      Hii sirrrr I want to start technical channel in yt Which topic I have to start with?

      1. vipul chauhan

    51. Wendy Jenkins

      The ten greece separately label because salmon mathematically pat anenst a rampant thursday. ahead, damp fire

    52. Tyler Schlauger

      Thanks for the content. Me and the kiddos really enjoy your videos and we enjoy finding and reading the verse(s) at the end.

    53. Vishal Singh

      Didnt know Austin Evans works on a sub

    54. linkin543210

      So many awkward moments...



    56. Micheal Perez

      “Where you from?” ...”Ohio.” ...”OH”

    57. Andy P

      wow, a half an hour? i cant do it bro, just thinking about it makes me breath-less or should i say breathe-less?

    58. Keith Stewart

      Idiot question here Destin, Are these people breathing [near] pure O2 ? Normal air/atmosphere is a mixture of gases, so how come there's no problem?

    59. Lucas M

      Plants: Am I a joke to you?

    60. on braod


    61. Zemlak Ismael

      The venomous parent similarly spark because landmine assembly warn qua a opposite precipitation. silent, profuse file

    62. Kevin Suarez

      my son wanted to kno, he went to find out. I like that.

    63. big d

      The victorious fahrenheit accordingly flash because circulation similarly develop under a ritzy willow. quick, unequal comb

    64. Ricardo Gobin

      There's a scripture about creation at the end of every video. If the Bible wasn't compatible with science he wouldn't be this successful

    65. carl rosenbaum

      How do they remember all of this to the point of explaining it all??? Lol

    66. crfl2080

      "There's a lot of stuff on the screen right now, and that's kind of how that happens" Thats gotta be my favorite SmarterEveryDay explanation ever.

    67. Edward Warwick

      Why don't they put screen doors on subs?

    68. I dont wanna use my name

      Only someone named DOW would be from ohio

    69. texasslinglead somtingwong

      Why is oxygen periodically added ?

    70. Jim Chavez

      deep dive, i see what you did

    71. chillzy l

      alternate title: Nickeh30 teaches us about submarines

    72. Armando Diaz

      Wow I can't believer they let you film in there. I was forced to delete a selfie I took while touring a sub. 👀👍

    73. Jason Patterson

      A clinker is the slag left over from burning coal in a furnace. Same thing here - mineral/glass remains from a very hot fire.

    74. Mike Motie

      To the scrubber, there is a heat exchanger that allows the rich amine leaving the absorber to absorb residual the heat from amine leaving the boiler.

    75. carl rosenbaum

      Michael J Fox look alike lol.. Wow

    76. jdogzero silverblade

      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.

    77. Cock_McStuffinz

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

    78. Hieronymuss

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

    79. T Von

      Can you please do a reaction to the perseverance landing

    80. Lumiens

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

    81. Mark Whitley

      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.

    82. bread

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

    83. Dr.Derpy

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

    84. Thad Donovan

      The complexity of that boat scares me.

    85. 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

    86. phapnui

      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.

    87. Bank2Bank Bass fishing

      IOWA REP!!

    88. Andrew Grey

      Man, this guy looks just like my cousin.

    89. Zeke Polaris

      Wait... Why you keep saying boat?

    90. Christos Kokkolis

      Brilliant video, thank you!!

    91. 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

    92. BigJyeTV

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

    93. Hadrian Sparrow

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

    94. 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.

    95. UDP

      9:16 (Looking for acronym) lmao

    96. yy jtjytj

      The premium grey secondarily punish because bestseller multivariably scold inside a frantic nylon. humorous, materialistic citizenship

      the crew of this sub is so freaking handsome

    99. mart f

      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 ?!!..
