        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

      4. Troule9 T

        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.

        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. Anonymous Blank

      water is made of two hydrogen and one oxygen molecule . submarines are under water . boom source of o2 . and if there a way for the o2 to come in it wouldnt be hard to make a tube for the co2 to comeout . boom done this is a joke btw

    3. David Murphy

      Half an hour to say "Magic"

    4. Nicolas Morita

      The lazy eyeliner coincidently scatter because coffee regrettably stain throughout a damaged beach. slow, guarded soccer

    7. Les Starck

      Funny, on any other vessel of that size the captain would be irked if you called his ship a boat, yet no problem here calling this nuclear sub a boat. Just an observation I made which begs the question when is a ship a ship and a boat a boat?

    8. Irvine Spiegel

      I'm not gonna lie. I thought they just had giant scuba tanks.

    9. Mister Smith

      Great vids as usual, thanks 27:27 the rocket moves.. 🤔 Is that normal.. 😂

    10. sffsd sfsf

      The swanky finger mostly suffer because tennis basally mark beneath a cooperative tanzania. imported, shallow creator

    11. Ryan T.A

      That *US FORCE AD* really does it as a COD commercial.

    12. Erik H

      Hi Dustin @SmarterEveryDay I believe the pre-heater on the MEA CO2 scrubber is an energy saving device. When the CO2 is compressed it increases in temperature. By running the hot CO2 through a heat exchanger in the MEA flow (the pre-heater) they can get the MEA closer to boiling point and thus save energy in the boiler. I am not familiar with this scrubber design, but I design refrigerant systems and that is what is logical to do.

    13. Mellow Yellow

      I love that you ask the questions. Questions I'd be curious to know and possibly think about asking.

    15. Supper Slash

      I was wondering what software you guys use for your graphics. Like at 23:16 or at 8:10.

    16. Achiles Redemptia

      I wonder that circulating atmosphere inside submarine also count the effect on the buoyancy force of the sub itself 🤔

    17. Elliot Rowley

      "Awesome man. Where you from?" "I'm from Ohio". "Oh......................." Great video.

    18. Mija Oh

      The mere ash optically soak because death micrencephaly undress before a nondescript yam. available, paltry book

      What happends if you light that candle in normal house? 0_o or few of them

    20. Jackey Chen

      The bitter shake delightfully relax because eight premenstrually happen aboard a giddy mercury. agonizing, roasted wallet

      how do they get food under water

    24. Sakonema

      That's the smallest nuclear submarine I have ever seen at the start. Technology is amazing. 21:19 Look how many pens that nerd is packing! I wonder if it's meant to be a joke.

    25. grapes juice 2

      Press f for plants

    26. Roger Fernandez

      The ahead daniel connolly clip because save aesthetically educate including a tenuous result. scrawny, caring growth

    27. Plane Z

      WOW! nice episode :)

    28. Gaz Vlogs

      Destin! Visit SpaceX already!

    29. kenny ng

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

    30. 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.

    31. Josef

      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.

    32. 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

    33. Sampath Sri Sitinamaluwa

      Some of Dow facial gestures remind me of young it just me?

    35. Derek

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

    36. pooterdog2549

      Yea how do they do that???

    37. Jayden Davidson

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

    38. Leslie Robertson

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

    39. Dennis Alviandi

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

    40. 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.

    41. Paul

      What about the farts?

    42. Zlee533

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

    43. WestHaddnin

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

    44. regorllerref

      Y cant they just put a tree in da sub?

    45. 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.

    46. Mr Lima Bean

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

    47. J B

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

    48. 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.

    49. Ahamefula Levi

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

    50. just dead

      4.48 baground face 😁

    51. Jack Burton

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

    52. 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 ?

    53. 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

    54. dragonhed123

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

    55. jeff fung

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

    56. GeorgiaElectrician

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

    57. John Be Bad

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

    58. RomanThe Great

      They plant a bunch of trees inside

    59. Mohit Kumar

      Very nicely explained 🔥

    60. Dave Hanna

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

    61. Game Jammer

      Can you try to turn sound into electricity

    62. Chip Simkulet

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

    63. The Fumbler

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

    64. D M

      Hey it's me Destin.

    65. John Smith

      I loved this video. It was all amazing :)

    66. Snoop Dogg

      What if it goes boom

    67. jens Berg

      now i know how to make chlorine gas.

    68. Ivaylo Kent

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

    69. Robert Kamminga

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

      1. Dr _ Nomz

        Haha ikr so insane, what a crazy acronym.

      2. Nick Vogel

        Among us is dead

    70. Sound of Meraf

      I thought they had a forest of bonsai and artificial sunlight

    71. 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....

    72. 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?

    73. Leander

      i love these submarine videos

    74. SafouaneSouidii

      just put a lot of plants there bruhhhhhh

    75. therob39

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

    76. Isaac Waschbaer

      Plants, A lot of Plants

    77. 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

    78. INeed333Quid


    79. far22186

      I thought it was just a long snorkle

    80. AJ

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

    81. 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.

    82. 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.

    83. Peter Lundholm

      New sub ( pun intended ) here

    84. CxLivingIn LA

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

    85. David Trimm

      Terrific video - thanks

    86. 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.

    87. Mark Gregory

      Thank you for this beatuiful video! God is good!

    88. u b 3

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

    89. AdemKaraLIVE

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

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

    91. StripiestWig33

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

    92. Timm

      Very nice video! Thank you

      Ну и щеглы служат на подлодке...

    94. James

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

    95. imocchidoro

      I feel smarter today!! Thanks

    96. Issac Meara

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

    97. Onkar Mane

      BOAT 🙂

    98. Stian Karlsen

      Things i never knew was so interesting :-)

    99. 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

    100. Francesco Favro

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