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

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

      God i miss subs so much.

    3. Burntsider

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

    4. 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.

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

      I thought N.A.S.A. was bad but as for this ! ??? You lot are raving mad if you believe this !

    10. Bernd Kalauer

      A clinker is an artificial stone created by some chemical process. Initailly used for bricks, later for the material ground into cement. Makes sense here. But why is the chemical reaction regarded safer than having pressurized oxygen on board? Yes, and for long-term use, the MEA cycle is better than the LiOH cannisters.

      Does the air pressure in the submarine get adjusted to the depth they are diving?

      If Nasa had't an issue with burning stuff in spacecraft, this could have been a crossover with the LEM topic.

      I would think fires would be dangerous in a submarine. Guess not.

    23. Booqueefious

      I like breathing air


      It would be a need to know basis as a lot of what goes on in a Nuclear Sub would be CLASSIFIED TOP SECRET

      Wow how things have changed in 50 years. I did two patrols on the second Ballistic nuclear submarine ever built, USS Patrick Henry SSBN 599. Crossed the arctic circle under the ice. I was an A ganger like most of the men in this video. It so early in the program they let old diesel boat enginemem on the nukes. EN2SS

      Us : wow interesting Russians : hey hey write tht down

    30. petegalvs

      Count on the US military to have the most sophisticated technology on the face on the planet, and yet still be using a monochrome screen that has a physical switch and uses an 8-bit processor to check the atmospheric conditions of their nuclear submarine.

    31. perezm714

      Can the excess hydrogen that is tossed overboard be used as a fuel?

    32. biggingeryeti

      What is this? A submarine for ants?

    33. KarmaVor

      They split H and O2, but only use the O2?! Wtf?! Hydrogen is not used at all for their engines or power?! Seems soo inefficient 🤣

    34. Glen M. Danielsen

      Fascinating. 💛🙏🏼

      Interesting how CAMS does not have a large comprehensive display that shows the status of _all_ sections of the boat at once in a single sweep of the eye. Crew member has to move a dial to cycle through the sections. Odd.

    46. The Other Side

      *How many videos have you made about submarines? Are the US Navy so desperate for kids to send to war that they are using you to make this so appealing? Thy know the modern generation are crazy about technology more than all those "democracy and freedom" BS. So they are using you to spin this.*

    47. ATMAtim

      I bet the sailor named Dow is related to the Alden Dow Chemical family of his home state, Ohio. Other than the ad at the end, this was a pretty good video.

    48. Stoner Davxuh

      I heard that they don’t accept people with mental illness?! .... :(

    49. Fat Man

      I am asking myself why they didn't use sodium perchlorate, I mean it contains one oxygen molecule more, so it should result in a higher oxygen output. Or would sodium perchlorate consume more heat and therefore be less viable?

    50. ung427

      2:01 Closed Captions: Where you from? "I'm from Ohio" oh.. "From Samfrasant Ohio" Cool man, nice to meet you! "Love you too.." So so what do what do you do up here? "So uh, shear um, wool, I'm a cheeseman auxiliary, Ridinger, er, a recent mechanical hobo, vellum, practically, 90% of the boat." So where are you monitoring the Oxygen levels? "So, to mock the Oxygen levels uh, sin, cup in the middle of em, tuck, back, cams? Yeah? "Central Atmosphere mocketing station? and uh, man come and watch any on a monitors, Oxygen levels on there. Can you show me that? "Yes?" ....

      I want to know how much methane builds up, and if they have to address that as well.

    53. Joel Miller

      My favourite part of this series is watching Destin interact with the crew, It's Awesome!! Destin just asks to see it and it seems they're not expecting him to ask but then just show him and explain everything about anything they're pretty clever cool guys.

    54. marn200

      that dude on 4:56

    55. Aaron Koch

      The oxygen was low because Destin talking too much.

    56. eric vulgate

      'clinker' is waste from an industrial process.

    57. mike anderson

      They don't make air. The government found it much cheaper to train everyone to hold their breathe while submerged.

    58. dash8brj

      I bet those oxygen candles contain the same thing as the emergency oxygen generators on aircraft, just on a much larger scale (the aircraft ones run for about 9-12 minutes, enough time for the pilot to get down to an altitude where the oxygen concentration is high enough that supllemental oxygen is no longer needed). It still defies logic when you hear the officer say "were going to make oxygen by burning this candle". In this case chemistry > logic ;)

    59. roundedges2

      Do they use this on the USS Enterprise space ship? Or do they use dilithium crystals?

    60. A M-E

      Where do they get Nitrogen (or some other inert gas) so as to not die of oxygen toxicity?

    61. 『Nafiscooldoo』

      Because we breathe daaaaa

    62. LisztyLiszt

      How bad is the smell of farts in that submarine? That's the key question really.

      Easy, just bring some plants inside the submarine.

    67. Breadbowl

      navy ships make their own nitrogen too.

    68. JuaniX

      Hi, Destin! As always, amazingly understandable and incredibly interesting!! Thanks a lot for your content!! Cheers!

      Don't worry, my Co2 scrubber and electrolysis equipment worked well for every submarine.

    80. Werner Hannefeld

      first thought - CO2 regen and/or electrolysis. studying submarine hydroacoustic systems in a navy military center at my high school btw. Fire extinguishing systems are an interesting piece of engineering, and so are hydroacoustic systems too! Destin, you are a true inspiration for millions of people, your videos are GREAT!!!! Please make more videos about submarines! Greetings from Saint Petersburg, Russia:)

    82. GamblerMarco

      As a 38 year veteran in the HVAC/R industry, I burst out laughing when I saw that leak detector. i was expecting some special, super secret Navy detection device... Instead, I see same basic detector used by any refrigeration mechanic in civilian life for the last 40 years... actually, that is a newer version of detector, but same basic design as the first H10 detectors

      how smart you gotta be to be staff member in a submarine? geee

    88. jwpx11

      Hey Destin I have a physics question for you, its kind of hard to explain while typing but it concerns controlling gravity. I think I have a 33% chance of this theory being correct, if you are interested I can give you my email later. Thanks, Josh.

    89. Даниел Кулевски

      So what happens to people if the oxygen gets too high?

    90. Yann Roger

      I would have said that they would use some stuff to fix the C From CO² and release the O² in the process. And add few more O² to compensate the O that goes more likely somewhere else than the CO² It was very interesting.

    91. Gedeon R Baez

      So water rich with Hydrogen or carbon could mean a sub is close?

    92. Cozy Rules

      Dude that’s amazing glad I randomly found this

      When you were explaining "the Candle" on the Sub, I was reminded of the scene from The Martian where Matt Damon had to burn something to grow potatoes. Was Is, that the same process?

      Matthew 25:31-46 New International Version (NIV) The Sheep and the Goats 31 “When the Son of Man comes in his glory, and all the angels with him, he will sit on his glorious throne. 32 All the nations will be gathered before him, and he will separate the people one from another as a shepherd separates the sheep from the goats. 33 He will put the sheep on his right and the goats on his left. 34 “Then the King will say to those on his right, ‘Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world. 35 For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, 36 I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.’ 37 “Then the righteous will answer him, ‘Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38 When did we see you a stranger and invite you in, or needing clothes and clothe you? 39 When did we see you sick or in prison and go to visit you?’ 40 “The King will reply, ‘Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.’ 41 “Then he will say to those on his left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels. 42 For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, 43 I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me.’ 44 “They also will answer, ‘Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?’ 45 “He will reply, ‘Truly I tell you, whatever you did not do for one of the least of these, you did not do for me.’ 46 “Then they will go away to eternal punishment, but the righteous to eternal life.” -------------- ---------------------- ========================== ----
