        @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.

      2. Chip Elliott

        How many candles do these subs carry?

      3. Dan Quayles ITS SPELT POTATOE!

        @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!

      4. Gw Builder

        @Stan Ervin Simple answer. The Chinese actually tried this exact experiment on the dark side of the moon in recent years with complete failure. Other similar experiments are being done on the space station with some success, but sunlight is still necessary. Some micro organisms were tested with success, but that information is apparently not available to the public. The idea is reasonable until put into reality. All known oxygen producing plant life (including algae) sufficient for human breathing require some form of sunlight in their photosynthetic process for oxygen to be produced. Submarines have been in existence since the Civil war, if there was a way to utilize plants in some form or other I'm sure the scientific community would be celebrating it right now. The Mars missions depend on such a discovery. There are multiple test facilities around the world challenging people to survive in the most inhospitable environments in preparation for the Mars missions and oxygen generation is the number one priority, water is second, and food, survivability along with many other situations follow in priority after that. In this instance there is overwhelming evidence in the proof of concept phase to eliminate that particular possibility, at least for now. I agree that there is always new information developing and the idea is absolutely reasonable to continue research because perhaps someone will indeed discover the missing ingredient. I actually grow, propagate, graft, and merge different species of plants and trees. Trying to maintain these plants in their optimal environment is challenging enough, imagine the types of modification required to sustain them without those systems. I am sure some of those modifications are probably happening on the station. The purpose is to go beyond the information we already have and explore new possibilities. I think the plant and algae ideas have huge merit; however, there are significant setbacks because with reduced sunlight oxygen production is reduced and toxicity is increased. The unknown is where the real possibilities are just waiting to be discovered.

      5. Dr. Lex Winter

        @Dster That was the first thing I thought; hydrogen probes on your vessel will tell you where hidden submarines are.

    2. wolfpackflyboy

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

    3. the Yesinator

      I am smartly dumb.

    4. Maherda Ekananda

      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.....?

    5. ideally CHIC

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

    6. ScottNJ

      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.

    7. Saintraft

      ahh yes... imagine if we had upgraded nuclear tech instead of abandoning it all these decades... fascinating stuff.

    8. Ck digital The Q of 6th

      They mastered the production task of O2 to last very long, but not infinate, which is why they surface eventually. This kind of 'Oxygen'nizing'(to nick name it) still renders in excise of carbon build up stored away, which could be combined with other elements, like say hydrogen to conjure food as carbohydrates, so on a planet like Mars, these resource are not to limited, depending where you are or how long you must be there, if humans ever master pure artifical production of atmospher, they wouldn't need a planetary realms to survive.

    9. Eric Starling

      I'm an ex A-ganger on an 688I boat. This exact boat type he visited. Awesome memories

    10. ʟᴏɴᴇᴠᴇɴᴛʜᴏʀɪᴢᴏɴ

      Does it really take 30mins to explain this?

    11. Little69

      Plz make a reverse osmosis video

    12. J Alexander Bill

      shocking lack of comments on Princess Boopersnoot.

    13. goguhu

      Kink is pretty much Dutch for 'brick'. It's the residue ash from burning, hardening into a ... brick.

    14. Bernie Lomax

      I used to build the HEX power supplies that run the oxygen generating equipment in the Ohio class. Small company called Treadwell had that contract and they outsourced most of the work to other contractors, we got a lot of that work for 30 years.

    15. Caesar Ong

      I cringed a bit when you said "filtered by reverse osmosis". We in the membrane community usually refers to filtration as anything mechanically separated, ultrafiltration is the cutoff for mechanical filtration, anything with smaller pores/molecular void spaces like nanofiltration and osmotic processes we call membrane separation. It can be a bit confusing since "nanofiltration" has the word filter in the name.

    16. Logan Cook

      Ask someone what happens if there is a leak on a nuclear sub. I'd bet the farm they would have a more intelligent answer than "well then we would have a leak". Thanks don petit. Sorry but you mentioned the lunar lander and i remembered when you asked Don about a leak in a space situation.

    17. Chuck Whitson

      I bet with the body odor, facts, bad breath it must smell terrible Inside after months

      1. Grampy Meyer

        It smells terrible the minute you board.

    18. Woody Wang

      Everyone knows people on subs take shallow breaths thats why....geeesh

    23. Revtune

      These ships literally have a natural gas plant on board. Amine towers, scrubbers, conditioners, yikes. Those things are jammed packed.

    24. diego g.

      21:35 how many pens does he has to carry?

    25. Dilan Singh

      I saw carbon dioxide kill co2 on cams and vent

    26. The chaos system

      Loved all this information and the candles that’s cool never knew about the candles but everything else expected knew about and keep on with the education much appreciate it and it’s always good to refresh your memory on things that way you can never forget

    27. Darren Swails

      20:33 look like an outline of a whale to his right..

    28. André Luz

      clinkers because of cement

    29. Shawn Wilson

      Thanks for helping me with my fish checkout 👍

    30. Revtune

      We use sniffers in the oil and gas industry to find gas leaks and other harmful gasses such as H2S and explosive gasses.

    31. newbiekunchannel

      Topic Suggestion!!! "Military MRE" how is made, what is the science behind the calories to an actual soldier is using (carring guns, ammo, supplies)

    32. Eddie

      Cold liquids tend to absorb (for lack of a better term) gasses more readily than warm liquids. This explains why cold amine is sprayed, compressed...etc.

    33. KodyKK

      To preface this I don't work on a submarine but I have ran amine units. Usually the exchanger to heat up the rich amine before the stripper is exchanging heat with the hot lean amine to cool it before meeting up with the gas, in this case the air. Lean amine usually works best when its somewhere around 15 degrees warmer than the gas it is coming into contact with.

    34. Jay Patterson

      Brilliant and detailed explanation of all the processes. I thought it was much more simple, and I had no idea they had to use oxygen candles and have a controlled metal fire onboard the sub, YIKES!!! Amazing solution but it seems so brute force when operating beside a nuclear reactor!

    35. UShaikh1

      today we become smarter with dustin

    36. Chucky Cheese

      That kid is so smart! What a nice lad

    37. Jay Playz

      So that’s how pavel stays down there so lomg

    38. Ziffer777

      But where do they get the nitrogen from?

    39. Jason Lin

      Do oxygen with baking soda right?

    40. Josh Keller

      Why wouldn't they be using the co2 as source of power

    41. ĶĮŁĽŔ-X / X-ÇŁÅŇ

      BAD GAS BUSTERS!! DO DO DO DO DO DO DO DO DOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!

    42. bleustraveller

      Bill Gates says cow farts and submarines cause global warming.

    43. JuJu B

      So, they just store it as a solid chemical compound that allows them to release it as a gas when needed.

    44. Bryan Duke

      Carbon scrubbers like in bubble less tanks in diving

    45. jeremy

      Sir we're going to need you to get back these candles get extremely hot. Destin: *gets closer*

    46. Erick Tun

      This was fascinating and educational. Thanks Destin!

    47. viktor gregovic

      Among us players:„cams”

    48. cam261

      Who downvotes a video like this? 😂 awesome stuff.

    49. Donkey Kong PEZ Dispenser

      So the burning a candle gives you oxygen and salty rust? Or is it rusty salt? That is so cool!

    50. 1Maklak

      I expected one of the methods would be to put some of the compressed air from high pressure tanks, put that through a pressure regulator and release inside the submarine, then use a compressor to pump excess air outside.

    51. Dj johnson

      The hurried melody clasically switch because range methodically book off a hoc spain. idiotic, sick cucumber

    52. Roary

      Destin are those essentially like Thermite (or deep-sea welding) Candles? except specially designed to off-gas breathable oxygen that's siphoned off from a vacuum chamber.

    53. GodOfCows

      "Soviet spy gets intelligence on US sub" circa 1969

    54. Craig Simpson

      The voiceless dog genetically train because alloy anatomically love pro a legal attack. arrogant, quack divorced

    55. Chop Labalagun

      in other words MEA means the submarine farts co2

    56. Ronald Leifur

      Petty officer Dow knows his stuff. Bump him up a pay grade 👏🏼👏🏼👏🏼

        Oh my god

    59. Dr. Lex Winter

      Who hasn't made an oxygen candle for fun? C'mon! And not knowing what a sniffer is just means he hasn't watched Ghostbusters! D: Or Das Boot for that matter! Shameful! That's now his homework for the day.

    60. 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!

    61. Rushi Mithagare

      Not nuclear science but it's submarine science

    62. just_a_guy

      4:29 hi there, phil swift with flextape!!! the super strong air proof tape *slap*

    63. David Prock

      Graphite and Urea works better than Stainless steel and KOH

    64. Dr. Lex Winter

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

    65. Lucas Pan

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

    66. LynxProd

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

    67. Dr. Lex Winter

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

    68. stoner420

      what do when run out of candles?

    69. Gnome Chomsky

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

    70. HugoDaBozz

      4:55 that guy looks like a blooper

    71. Alan Winge

      Do they have beans on the menu?

    72. LynxEng

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

    73. hn4200

      Can someone give me a tldr answer plz

    74. frodev

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

    75. Parzival1780

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

    76. 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.

    83. ramp agent 92

      Where can I get one of these candles?

    84. 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 😶

    85. Tim Kimmel

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

    86. Łukasz Tokarski

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

    87. 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.)

    88. 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?

    89. Absolute Territory

      Hey I knew chapman, served with him!

    90. Adam Armstrong

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

    91. Ryder Scheeren

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

    92. 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.

    93. Vincent Pang

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

    94. mikajlod25

      But how do you get the body odor out?

    95. Dingle Berry

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

    96. 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.

    97. Hoagie27

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

    98. eSSentialplays

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

    99. Chalol Meza

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