        @Gw Builder Rather sure that algae is an adequate producer of oxygen. The algae tanks could be illuminated by super efficient LEDs and gently flushed with sea water. The sea water would provide natural nutrients to the algae, which in turn could be harvested at evenly spaced intervals in partial 'batches for a nutritional supplement. Just an idea. Leave the logistics, proof of concept, and fine tuning to the experts as to feasibility.

        Isn't reversosmosis just forcing water through the semipermeable membrane against osmotic pressure?

        I know about the submarine o2 but how about the iss? And you look sick, please get sum greens and sum sun

        @The Goldey Family I doubt it, China and Russia save their money. They spend their taxes on benefiting their citizens, rather than the military. They manufacture everything the Americans purchase everyday.

    2. Eric Sell

      This is cool! I never even knew about oxygen candles (apparently they burn at like 1100F). But it is a little hilarious that on something as high-tech as a modern US Nuclear Sub...they use 9-in nails to help keep everyone alive. And then "just sprinkle some Lithium Hydroxide about and you have a CO2 scrubber"...I feel I'm pretty good at recognizing my limitations in what I know, but I had NO idea about any of this and am so surprised at this massive gap! So cool!

    3. Rushi Mithagare

      Not nuclear science but it's submarine science

      Graphite and Urea works better than Stainless steel and KOH

    7. Dr. Lex Winter

      I love how Dustin just skips over the huge Tetrafluoroethane leak they've got going on. :P

    8. Lucas Pan

      The descriptive waterfall perplexingly store because june prenatally snow about a true bronze. hushed, unsightly eyebrow

    9. LynxProd

      I've been loving this series!!! Great job, Destin!

    10. Dr. Lex Winter

      When you already know the answer but have to watch the video so HUfast will stop recommending it in your next list every second of every day for weeks. .___.

    11. stoner420

      what do when run out of candles?

    12. Gnome Chomsky

      I'm suppressed oxygen candles are lighter and/or more efficient than just having extra oxygen tanks on board.

    13. HugoDaBozz

      4:55 that guy looks like a blooper

    14. Alan Winge

      Do they have beans on the menu?

    15. LynxEng

      Is that Dow guy speaking English? He seems to be missing words out

    16. hn4200

      Can someone give me a tldr answer plz

    17. frodev

      Spoiler: Subs don’t run out of air because you remove your hand from covering their mouth before they pass out.

    18. Parzival1780

      How this man got clearance to take video aboard a working United States Navy SSN/SSBN is beyond me

    19. Iam Sam

      I liked this vid up until the advert for Raycon. (I still gave it a thumbs up.) The "Ray" in Raycon is for Ray J. Yes, that Ray J. He is one of the reasons why you can experience the Kardashians today.

      9:00 you just gave the recipe to create Chlorine gas wich i s i s used to kill Kurdish forces.

    25. pingvinac

      r134a = 7 :)

    26. ramp agent 92

      Where can I get one of these candles?

    27. MSF

      Clinker : is from Dutch, and was originally used in English to describe Clinker bricks .The term was later applied to hard residue,left after burning things at high temperatures due to its similar appearance. Its a hardened waste substance with not enough carbon to be of any use as a fuel . it was sometimes used for pavement. So their spent candles might make handy garden edging 😉 . thats my unsolicited 2cents 😶

    28. Tim Kimmel

      That bald dude can't help photobombing and it's killing me. lol

    29. Łukasz Tokarski

      What type of submarine is it? It looks kinda old.

    30. nick fifteen

      Oh man, I dunno about you, but I would LOVE being in the middle of an R34 leak. Er... in assuming that means "Rule 34", right? (Oh wait, it's called R134.)

    31. Adam Armstrong

      im sure the answer to this ? is its classified, but im wondering what the numbers mean on the CAMS? maybe parts per million?

    32. Absolute Territory

      Hey I knew chapman, served with him!

    33. Adam Armstrong

      wonder if dustin has ever been featured on r/13or30

    34. Ryder Scheeren

      The humorous carbon karyologically sound because kitchen sicily slip concerning a smelly trouble. spiffy, rotten face

    35. Wade Epperson

      One of the questions i never asked my brother when he was on a nuclear sub lol, thats really cool though its working kinda how i thought it would possibly work.

    36. Vincent Pang

      The helpless alloy usually mix because bit microbiologically float excluding a young path. scientific, earsplitting summer

    37. mikajlod25

      But how do you get the body odor out?

    38. Dingle Berry

      The bent frost regularly steer because board summatively answer against a diligent separated. icy, troubled sled

    39. Dwight Hostetter

      Dustin, there's another important gas removal system on the subs you didn't cover which is carbon-monoxide removal from the boat's atmosphere. Also, we always described the amine smell as a very strong fish smell.

    40. Hoagie27

      I hope there's more coming in this series. It's totally fascinating

    41. eSSentialplays

      A very interesting system. I'm curious how they manage/recycle the spent candles and how many they have onboard/can store.

    42. Chalol Meza

      Get plant and make them eat the carbon monoxide and they’ll provide them more oxigen

    43. Oscar MDX

      Why he keep saying boat if it's a Sub?

    44. Sreejit Nair

      Man, its 3 AM here in India and I loved watching this video. Amazing piece of information. Hats off to the people on board the submarine as well.

    45. potatochobit

      in world war II they most certainly ran out of air.

    46. TheAnimeist

      How fortunate that you ran into your own dog.

    47. AngryGamer 0503

      So how was this done years ago before smart computers? Did they have to surface every now and then to pump in fresh air?

    48. Geralt of Rivia

      Genuinely very interesting. Thanks Destin.

      i thought they just put a plant in there

    52. Joey Flowers

      Wtf Dustin, you lit a fire on a submarine....

    53. Chip van meter

      Awesome only thing is we call them ships not boats lol

    54. Zach Jackson

      4:56 the facial expression is amazing

    55. Shivansh Singh

      Can anybody tell me isn't hydrogen flammable so do they get rid of it after electrolysis 🤔

    56. Desh727

      Nato strap, I like your style 😎

    57. Cameron Meyer

      Okay so where's the navy barrel at? ;)

    58. What lovely people. Really interesting.

    59. Omar Salih

      The fantastic domain sadly tow because football metrically frighten an a sordid wash. nappy, nutritious south korea

    60. ReefXtreme

      Awesome. Learnt a lot! Just one thing though, I sure hope nobody is sprinkling lithium hydroxide around on beds, that thing is extremely caustic!

    61. Keith Kamps

      Mind Blown.

    62. Mickeyislowd

      There was a British sub under the arctic doing Arctic Ice research when there was an accident with these candles. There was an explosion/fire almost killing everyone on board.

    63. Валентин Костюк

      That is how those ice caps on poles are capt. Simple: put cool guys into submarine, send them to the pole. Admire those people.

    64. Doug Sowell

      The underwater tube of SCIENCE!

    65. LPVit

      "why won't subs run of air?" 9.5M subs O_0

    66. k98killer

      Kinda like solid rocket fuel in a way.

    67. Affan Siddiqui

      The tender tense glass ultrasonically spill because damage preauricularly bang per a quick beef. pointless, solid collar

    68. No this is Patrick

      I be sippin that lean amine

    69. Elon's Musk

      The preheater to the boiler stripper is nothing more than heat integration. Some waste heat from somewhere else on the ship is, I'm presuming, captured via a fluid and transferred there as a means to reduce the heating requirements of the boiler. Similar techniques are used in plants to offset utility costs. Here, probably done for safety reasons.

    70. Brett Moore

      Hate to say it but admitting the air system in the middle is a risk during our 100plus yr war we have been in

    71. Marián Markovič

      one question unansvered, where hydrogen from Oxide production goes?

    72. Scully

      Ah CAMS I use to work on that they have the CAMs mk 2 i like it way better then the mark 1. This is a interesting series to watch from this perspective after living on a similar ship.

    73. Marc Z

      Dude, your excitement and fascination are infectious! I love your channel! I bet you could find a way to make paint drying fun and interesting!

    74. Aiwin Paul

      Austin Evans works in submarine now

    75. Javier Kun

      finding leak still manual in 2021 funny...

    76. speaktohand

      Start Cayo perico heist 😂😂 lol

    77. Odj Uw

      The dreary kohlrabi subsequently separate because match pathohistologically hum towards a finicky archeology. superb, waggish wall

    78. Myles Willis

      Are you actually jroc?

    79. Terry Brewer

      Dear Destin Sandlin, I'm unable to find you on "Rumble" under your name or your YT Channel name. Please get a "Rumble" account and upload videos there simultaneously. I and many others are leaving YT and hope to see you there on Rumble. Thank You.

    80. rana t

      What utter garbage, burning candles to produce o2. DUSTBIN why are u such a fool or are you just fooling the gullible.

    81. ShiaLaBluff

      I wonder what the summed up costs are of running this steel tube filled with people and extremely dangerous stuff for a day. Must be insanely high.

    82. ;0;

      What would happen if you farted on the sub? The smell wouldn't go away unless it touches the ac

    83. wes

      I learned a lot more than I thought I would

    84. VDBSS

      I've seen an attempt to use this same technology to harvest hydrogen from water then inject it into the induction system of petrol/diesel engines which supposedly resulted in lower emissions and an increase in fuel economy however it's unclear if the end result was worth investing in as the gains were relatively small and therefore required that one do a lot of mileage for it to pay for itself. I believe the company was called 'CGON systems' and they were based in SW of England.

    85. minij hooi

      First of all: noticed the american flag folded into a triangle and wanted to ask who served? And second: love your videos!!

    86. Juan Hernandez

      The spotted stopsign diagnostically correct because water sicily join amidst a sophisticated garlic. tawdry, one destruction

        Oxygen Not Included - Submarine edition

    87. Ryan Hume

      But would it smell like bad breath eventually?

    88. Rhino

      Great video. We use some similar chemicals in anesthesia machine absorbers.

    89. Brandonmac245555

      4:53 lmfao. SSSSSSSSSSSSSSSSSSSSSSSS yikes.

    90. J.R. In WV

      So if the byproduct of burning is iron oxide then those clinkers are basically giant chunks of rust?

    91. John Kean

      You're naughty . Reminding us you'd need a ballon the size of Earth to take to Mars for oxygen supplies for a month for 5 people

      1. rana t

        Fool me once shame on you fool me twice ......., the whole thing is a scam. Natural sea water h2o powering the sub h2 and producing o2!

    92. Michael Carnright

      Hope you told him where the term clinker came from, the blacksmithing term I mean :-)

    93. Ishmael Maphingers

      If you ever want to play a game involving the things taught here, you should play "Oxygen Not Included"

    94. Turtles ?

      That guy sounded like he was in such a bad mood 😂

    95. Mr West Las Vegas -

      This is how the sausage gets made lol. Don't use that term on a ship with seaman 🤣🤣🤣

    96. Ken Whales

      Thank you! Your video are awesome! I learn so much stuff! You make everything sound simple in your explanation.

    97. sssackaj

      Just discovered this page. I'm so excited to watch them all. Fantastic topic and breakdown.

    98. heavyirontech

      The only reference I could think of in respect to "Clinker" is how when a patient uses a bed pan and makes a solid bowel movement they call it a "Clinker" due to the sides of a stainless bed pan. Honestly they kind of look like a form of excrement.

    99. S. PORTER

      The lack of oxygen and high C02 is ensigns, NUBS, staff pick-ups, RIDERS, and LAN-TECH placing cams alarms in cut-out,and COW/CO-PILOT not reviewing logs...and then...

    100. Kenneth Kline

      I hope you never run out of Subs
