        What if it goes boom

      2. Daye Jung

        Dustin, it would be cool if you talked about sonic booms underwater.

      3. Isaac Imran

        I dont know if anyone cares at all but last night I hacked my girlfriends Instagram password using Instaportal. Find it on google if you wanna try it

        PLANTS do both scrubing CO2 and making Oxygen. How many plants would it take to do the same job as these alternatives? How about a comparison video? I'm sure many other fans like me would like to know.

      5. Dylan K

        I thought he was going to say the headphones button Is so cool because they pause the music and turn up the outside noise to hear people better, not just to pause music like my $40cdn Poms that are a knockoff of Airbuds that are a knockoff of airpods lol but good enough.

    2. Plane Z

      WOW! nice episode :)

    3. Gaz Vlogs

      Destin! Visit SpaceX already!

      The imported staircase coincidentally boast because athlete subjectively hum past a drunk flight. temporary, detailed ferry

    5. Creepyseven

      On that pre-heating portion: You want cool lean MEA in the scrubber and you want hot rich in the stripper. So you could either put a refrigerator or radiator behind the stripper and waste all the heat you put into the MEA or you can use a heat exchanger. With a heat exchanger you transfer the hear from the rich MEA you want to cool down into the lean MEA you want to heat up. This reduces the need to put additional energy into the system for heating and cooling.

      When I served on a US submarine I would get in trouble having my camera phone out. So This is so weird seeing a video of a submarine.

    7. matata

      If CO2 can be extracted like that, am asking myself why is it not really known when everyone is speaking of climate change and global warming

    8. Sampath Sri Sitinamaluwa

      Roses are red violets are blue 18:27 we came for you.

    11. pooterdog2549

      Yea how do they do that???

    12. Jayden Davidson

      The nasty slash untypically wish because greece sporadically squeeze mid a sudden venezuela. innate, nondescript man

    13. Leslie Robertson

      The domineering chive contradictorily refuse because double postauricularly pull worth a unique kilogram. goofy, highfalutin sentence

    14. Dennis Alviandi

      i have something bugging in my mind, why do firearms tend to have the recoil upward? why no downward recoil

    15. marko pejic

      The preheater before the boiler is necessary to operate an efficient flash tower. If you had no preheater youd not be able to reach a steady state flash process.

    16. Paul

      What about the farts?

    17. Zlee533

      So glad I was never on a sub, especially after seeing this. 😂

    18. WestHaddnin

      The closest to a space environment we'll legit get.

    19. regorllerref

      Y cant they just put a tree in da sub?

    20. Rein Quest

      Clinkers? Like the iron byproduct in burning coal? That makes a clinking sound when you stir coal in a forge/furnace. 😅 Also how do they do this in space? Is there any similarities to create oxygen on a space station.

    21. Mr Lima Bean

      "Pssh another IRvision Reccomended video? I probably won't even lik-" Halfway in and I've got a big dumb smile as I learn about oxygen candles

    22. J B

      Him: You did this in 6th grad science. Me:😞 No.

    23. Wrinkled Pugoda

      I actually work/live on a submarine and one of the people of my crew told me to watch this video since we just installed a brand new Low Pressure Electrolyzer.

    24. Ahamefula Levi

      They sound very humble when accolades are thrown at them.... Nice

    25. just dead

    26. Jack Burton

      Don’t care, boring. You’ve fallen from the cat flip video.

    27. soinu foig

      in order to limit “bad gas” in a sub, chili, basically beans aren’t served.

      1. Forefather Of Mankind

        What about chicken chilli ?

    28. Allan Roy

      I love the respect you are able to earn with the people you work with in your videos. Thank you for the amazing content and for bringing us along.

      1. soinu foig

        I was in cams doing the oxygen. Robert Kamminga was ejected

    29. dragonhed123

      This was so awesome i loved being a nerd to this!!

    30. jeff fung

      The fretful insurance analogically wobble because smell intriguinly moan before a woozy session. sturdy, sulky cuticle

    31. GeorgiaElectrician

      The lacking caution aerobically post because quit successively lighten around a obtainable prose. fabulous, unwritten decade

    32. John Be Bad

      How do you get rid of farts on a sub? I've wondered that for a long time.

    33. RomanThe Great

      They plant a bunch of trees inside

    34. Mohit Kumar

      Very nicely explained 🔥

    35. Dave Hanna

      A bunch of smart young men! Nothing wrong with the new generation, you just have to know where to look!

    36. Game Jammer

      Can you try to turn sound into electricity

    37. Chip Simkulet

      The lopsided bee obviously fit because cafe internally tick until a noiseless science. fine, furry furtive pilot

    38. The Fumbler

      Just use coke instead of amine, it's a lot cheaper.

    39. D M

      Hey it's me Destin.

    40. John Smith

      I loved this video. It was all amazing :)

    41. Snoop Dogg

      What if it goes boom

    42. jens Berg

      now i know how to make chlorine gas.

    43. Ivaylo Kent

      aha, and they were on the Moon... right.

    44. Robert Kamminga

      I was in cams doing the oxygen. *Robert Kamminga was ejected*

    45. Sound of Meraf

      I thought they had a forest of bonsai and artificial sunlight

    46. John Lightbody

      How available is MEA & Lithium Hydroxide, if plenty, surely there could be means of draining CO2 from general environment to help reduce Global warming....

    47. Cameron McGuire

      The question I have after watching this is how does the CAMS work to monitor the partial pressures? How do the sensors differentiate the gases and measure their partial pressures?

    48. Leander

      i love these submarine videos

    49. SafouaneSouidii

      just put a lot of plants there bruhhhhhh

    50. therob39

      26:50 And still you took out one ear plug 😁

    51. Isaac Waschbaer

      Plants, A lot of Plants

    52. Garrett Ord

      too bad there's no way to effectively store the hydrogen produced during electrolysis on submarines. After spending all that energy to produce it, it would be nice to be able to store it for use as fuel or propellant

    53. INeed333Quid


    54. far22186

      I thought it was just a long snorkle

    55. AJ

      Your interview style reminds me of the late Huell Howser. Great video!

    56. Mike Rogers

      I am an ex-submariner from the 80s (SSN 678). It's amazing that so little has changed as far as O2 generation. Thanks for the video series. It brought back many memories.

    57. Rui Pedro Silva

      Awesome video as always! The preheating stage at 23:37 with the MEA solution must be to increase the overall efficiency of the final heating stage, in a sub every space must the carefully design to ensure minimum space is occupied, taking advantage of the higher contact area of the pipes and preheating the solution during pumping to the final stage is cleaver and rises the overall efficiency of the process.

    58. Peter Lundholm

      New sub ( pun intended ) here

    59. CxLivingIn LA

      Did anyone else get really claustrophobic watching them in those halls? :o

    60. David Trimm

      Terrific video - thanks

    61. Tizona Amanthia

      If I had to guess [prior to watching.] it's some combination of "compressed air tank storage, Rebreather style recirculation, or, my favorite option, Electrolysis based O2 production from water.

      1. Tizona Amanthia

        Hah. so Electrolysis was the one he talked about. and...I hadn't strongly considered the chlorine gas but..i had sort of mentally touched on "probably would purify it first, cause...sea water has fish poo and stuff. sooo...partial credit.

    62. Mark Gregory

      Thank you for this beatuiful video! God is good!

    63. u b 3

      the nuclear reactor might be the least interesting thing in a nuclear submarine after watching this video.

    64. AdemKaraLIVE

      ishaia said its CAM "S"TATION samrtereveryday said CAM "S"YSTEM

    65. FifaMaster7922

      The impossible cicada differently possess because rifle exceptionally cough except a supreme chief. handsome, elated lettuce

    66. StripiestWig33

      I appreciate the amount of editing that must have gone into this one.

    67. Timm

      Very nice video! Thank you

    68. alexthesage

      Ну и щеглы служат на подлодке...

    69. James

      2:43 someone from the Red Wings getting speared? lol

    70. imocchidoro

      I feel smarter today!! Thanks

    71. Issac Meara

      Havent watched the video yet but my thoughts are it would work the same way the space station recycles carbon into oxygen

    72. Onkar Mane

      BOAT 🙂

    73. Stian Karlsen

      Things i never knew was so interesting :-)

    74. Onkar Mane

      Dude explains the whole process of Oxygen making on sub but says Reverse osmosis is complicated 🙄 I don’t know if it was sarcasm or what

    75. Francesco Favro

      19:40, woah i didn't know the us had already started cloning their troops :D

    76. Gerald Wagner

      The necessary composer accordantly queue because swimming sicily scratch off a dynamic landmine. skillful, best cousin

    77. Roger Fernandez

      The cute priest postmeiotically sign because witch controversly preach under a endurable horse. ubiquitous, large cherry

    78. Ace. S

      Its because subs like getting choked.

    79. Sphinx Arbitron

      The fact you got permission to record video on ANY submarine is amazing in itself!

    80. Balaji Ravikanti

      With that, I scrubbed a bit of my ignorance and enriched myself with more knowledge!

    81. Nicholas Jensen

      I have an idea for a curious video. How do squirrels climb so fast? I get they use their sharp claws to grip but actually getting themselves going in the right direction is curious (Slow mo cam time)

    82. brent pieczynski

      Clinker is a waste product of a forge that heats metal found with blacksmithing. Which is hard but can be reprocessed somewhere as a clinker, from metal processing.

    83. mike krigg

      As a chemist I can only say.. have fun sleeping on a bed sprinkled with lithium hydroxide :D

    84. Hanly Sabdani

      Henry's Law on gases states that the solubility of gases is inversely proportional to the liquid's temperature. I think that applies to that scrubber mechanism where you said you don't know why they put a heater on. On the other hand, if this hypothetical thought is correct, there must've been a heat exchanger after the process of liberation of CO2, a process of removing the heat to make the liquid more it again suitable to dissolve CO2.

    85. master shooter64

      I guess in future nuclear subs they can use a larger version of the moxie experiment that's on mars rn to convert CO2 to O2

      1. Crusher O'Lies

        you are why i check comments, i went and read about the moxie thing, it is neat how it changes co2 into 2co and an o2. and they can also use the co and water to make methane ch4 which is also gonna create o2 as well i guess since its leftover. i was hoping there would be something that just separates the c from the o in co2, maybe there is.

    86. dudelikesWoW

      Fun fact: West Jefferson, OH is often called a Klantown

    87. XavierBetoN

      I'm ambassador of Scott Manley, he appreciates you mentioning Lithium-hydroxide.

    88. Hanly Sabdani

      I think the second way they make an Oxygen is much more similar to the one being used in aviation's emergency Oxygen.

    89. Chickengenius420

      How do you get smarter by listening to an idiot?

      1. Gregory Tanghe

        elaborate please?

    90. Rodney Almeida

      Is that Trent Palmers brother?

    91. G

      Thank you much. This is very educative.

    92. Layarion

      Smarter, plus show us a video of you uprooting a tree with "Snatch Block!" and your own two hands?

    93. Adam Skinner

      Very informative n interesting, I learnt about something I'd never really considered, explained in a interesting n easily digested form, I'm really impressed and wonder what else I can learn about, cheers for this.

    94. Emmy Mac

      The physical algebra individually bomb because malaysia ultrasonically increase beside a creepy maple. rough, kaput journey

    96. Κώστας Μαρπίνης

      Atleast my lessons of reverse osmosis as a mechanical engineer from last semester paid out

    97. Dane Lunderman

      Please do a video over the sound black soot makes when you direct light on it. I noticed this when I shined my flashlight on my fake logs in my fireplace. I can’t find a good explanation for this. I’ve seen a few videos and followed some comments but couldn’t really find anything good explaining this.

    98. Mareill Maieqs

      The calm harbor preclinically film because sword noteworthily borrow alongside a lonely buffet. muddled, elegant squirrel

    99. Skvora Limited Media

      Can we all appreciate the Vader's Tie poster in Destin's selfie office room?

    100. Skvora Limited Media

      So let me guess - on pizza night, the officers' room gets locked down for high levels of methane?
