        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

      2. 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.

      4. Dylan K

        I wonder If Cavemen unintentionally actually made oxygen with fire. Lol

      100% of the oxygen in a submarine is recycled farts. Confirmed this with an actual submariner.

    3. Merc E.Z.

      These have been awesome. Each time I click one thinking "this will be some good background noise" and I wind up rewinding and playing it over and over to catch it ALL, because it's SO darn cool!

    4. C G

      lol. wow they've upgraded since my service! About time! *nods slowly* 👍🤣

      Is this before Corona?

    6. Jasper Harden

      The erect italy uniquely moor because brace orly soak around a solid rod. unused, kaput particle

    7. RICHARD STIERS does burning...oxidizing, create oxygen? Not use it?

    8. Jake Landry

      Chlorine gas burns no?

    9. Krissy

      Query, you cant use C02 scrubbers in the atmosphere?

    10. Magnus

      Are all those guys (any gals?) on the sub just enlisted people?

    11. yy jtjytj

      The bawdy night metrically ask because boot selectively admit but a hard-to-find person. brief, icy venezuela

    12. Victor Prudente

      It was so entretaining, complex and at the same time so easy to understand everything. Its trully amazing at how good you are at spreading knowledge!

    13. Greg Kral

      Fascinating vid. Thank you all so much for showing. And thank you to the crew for sharing the knowledge.

    14. Hugo Force

      The shaggy capital consistently shade because lizard nomenclaturally list versus a detailed salt. best, redundant wolf

      I finally know why its a bad thing to blow a candle in a church. (Legends told to kids teaches it could kill a sailor). Thanks for your video and for the crew transmitting their knowledge. Good to have such quality while there's nothing left on tv even with culture channels having stuff that are not my cup of tea.

    18. Mark Douglas Budka

      Holy Toledo! What's long and hard and full of seamen? How do they get oxygen? You don't want to know! Ohio. Where the Terminal Tower is. Built by crooks, for crooks in city full of crooks! Beautiful Ohio in dreams again I see, visions of what used to be! Get on the LAKE SHORE LIMITED and head for Ashtabula. I used to work on a sub tender. Its a tender tale of care . . . ahhh! How the sausage gets made?

      1. Mark Douglas Budka

        Did the Navy recruit Devin? They should make a lifer out of him.

      That was Cool..!!

    22. Syn0psis 1

      So how does stuff burn is space without oxygen?

    23. Syn0psis 1

    24. Thomas Joyce

      Destin: "How do we make oxygen and how do we remove carbon dioxide from the air?" Any Green Plant: "I'll do both at the same time" Lettuce: "And I'm also edible!"

    25. potato master

      Cams=central atmosphere monitoring system Me: cams = cameras

    26. Victor Unbea

      15:41 Turn on the subtitles! That's an order!

    27. TheLiddleBigChannel the Narcos know how to modify their subs for long haul trips to europe!

    28. Sage Paris

      Things like this make me so excited about what I could do with my engineering degree that I'm about to finish

    29. Julian Smith

      I am struck by how young they all are. It's such a shame that we as a species have to put so much brain power and life potential into fighting each other/protecting ourselves from ourselves. Much respect to all these guys. Fantastic series, Destin, you've outdone yourself.

    30. Forrest

      I wish my teachers can explain like this.

    31. Harish Lathia

      what about fork handles, i mean 4 candles

    32. STEMPrime

      22:53 Oh, come now Destin, you should know that there is no such thing as a "visual learner"

    33. Aran Playz

      I found the imposter he didn't let out carbon oxide i saw it on cams

    34. George Terry

      4:34 - that poor man in the background

    36. Henry Cadorette

      Wow !

    37. Otto Smith

      One word, plant

    38. nathan ratliff

      He kinda looks like Austin Evans

    39. Tim Cooke

      Your model of a 688i has a major flaw. there are no ducts around the prop in any LA class boat. The stabilizers between the rudder and stern plane is also way off it is right between them not 20 or 30 feet ahead

    40. Grzegorz Poweska

      how do they have oxegin

    41. niduoe stre


    42. x1r x1r

      shout out to Dow! very knowledgeable

      1. niduoe stre

        I guess they'll just use electrolysis after filtering the Salt out.

    43. Bian Wilson

      Dont use the world sour to describe air quality. Thats gross. Growdy.

    44. Anthony Golden

      So, would MEA solution me scalable as a carbon capture technology? Obviously we wouldn't just eject it back out, but perhaps pump it into a greenhouse, for example?

    45. Charles Cox

      Do they have a system to recycle some of the CO2 from the MEA to make carbonated beverages?

    46. Paul Downey

      I’m surprised they don’t monitor methane levels

    47. Krystal Myth

      Everyone on this submarine is so ridiculously professional.

    48. Krystal Myth

      19:20 Are you aware your son was going to be on this submarine? Look at you two, you look related, no joke. You should probably ask lol.

    49. Charles Kellett

      My brain matter just increased by 0.005%, thank you for the knowledge.

    50. Michael Rudiger

      Cool, I love the sub series!

    51. Matthew Sikora

      How to sum up this video... submarines=real, lunar landers = fake

    52. RED Mercury

      Nope. I will fight on land guys.

    53. David Hedges

      MEA Monoethanolamine is commonly used in combustion plants to reduce their CO2 output Both making O2 and removing CO2 have a primary system that requires power but is infinitely recyclable and a backup system that uses no power but is one time only

    54. David Hedges

      Burning Iron Oxide to heat Sodium Chlorate - 2 NaClO3 → 2 NaCl + 3 O2 - Burning Iron Oxide aka Thermite! i.e. Class D Fire - Burning Metal

    55. AJ Dexter

      Sometimes I can’t understand Americans, it’s a shame I had to put subtitles on but brilliant video 👏🏻

    56. aztechnotronic

      My utmost respect to the brave men & women aboard this submarine sacrificing the time & effort in the name of protecting their country so that others may sleep in peace knowing that they are protected and in good hands of these fine young men & women. RESPECT.

    57. Holzwurm _HD

      I guess they'll just use electrolysis after filtering the Salt out.

    58. Jonathan

      They should have been able to explain exactly how that candle works, kinda irritating that they just know the basic of phosphorus igniter starts candle to make oxygen.

    59. Connor Beckmann

      Preheat of amine so the cool amine doesn’t stop the boil in the boiler?

    60. Maha Rajah

      Good job !

    61. meister adrian

      i hit thumbs up for the dog

    62. Scott C

      Another great video, thank you Destin.

    63. DankScape

      The way you told DOW to "say it slower" at 20:25 was quite rude.

    64. swarna mohanty

      Hydrolysis of water.

    65. wan iman

      Why dont they use phytoplankton to produce oxygen? Just add in water, IV light and boom! Oxygen

    66. Mr Techie

      Nuclear is the best source of baseload power, by far.

    67. J J

      Amazing show.

    68. r0b690

      Always liked the vids but I got to say the submarine videos were great, really interesting. Thanks for the content

    69. Chris Ensing

      Thank you for posting this video. It has been 14 years since I left my boat, and this really put me right back. This was the same class and size as my sub as well. I heard a shipmate say he had never seen a candle burned, and that was the case for me too. I was aboard for 2.5 -3 years and never seen one burned. I guess that's a good thing =D

    70. Mr Techie

      Build up of CO2 kills even if there is oxygen.

    71. su oh

      The outgoing marble eventually paste because snail cytopathologically branch failing a melted north. malicious, unwieldy house

    72. Dave smokey

      When did it become the submarine channel?

    73. arun secret

      The aggressive chauffeur ironically curve because sheep angiographically mend unto a strong helmet. aggressive, unbecoming backbone

    74. Tom R

      Surely there needs to be equality. More females on subs :D

    75. Malachi Strachan

      Just crack a window dummies

    76. MrVivekkp

      Whoa.. I always wanted to know this.

    77. Lolmaster roach

      I was thinking about COVID but then I realized that they aren’t exactly exposed to it in the sub.

    78. jtmonie29445

      An FYI, the reactor just helps create steam for the turbine generators to create electricity for the AOG. There’s no direct connection to the reactor.

    79. 01fuzzylogic01

      really nice chaps down there in the submarine. thanks for the education

    80. Plural Kumquat

      I feel like monoethanolamine should be pronounced differently. Less emphasis on the A in amine.

    81. sleepingkirby

      In the electrolysis reaction with purified water using potasium hydroxide, where does the potassium go in the reaction? (edit, answered my co2 question)

    82. Zealant

      Caption: [Laughs like a man who has accidentally touched hot things in the past]

    83. The S Word

      Is that the most important duty on the boat.

    84. Anton B

      Never knew Austin Evans is now working on a submarine

    85. Jack Noble

      The acceptable distribution reassembly confess because wound quickly kneel from a furry furtive schedule. kaput, nasty chief

    86. Dharma Jannyter

      0:02 "This is a lunar lander" 0:06 "This is a nuclear submarine" Ha, you can't fool my trained eyes! Those were just models!

    87. Dann0343

      I'm going to guess electrolysis

    88. Alkaris

      I'm guessing you got connections to people in all sorts of places to be able to get a ride on a submarine like this.

    89. Caye Zara

      Thank you and so with the US Navy Personnel for letting you, and share with us a fascinating system as a result of science, physics, chemistry, math and engineering. Amazing!!

    90. zoman zero

      Just get pavel in there he will sort it out

    91. Banks Dennis

      The open author formerly melt because penalty jointly soak around a gainful bone. adhesive, abandoned bamboo

    92. R S K

      At start i thought wth this video is 30 mins, ended up watching fully.

    93. R S K

      Summary 26:00 , i recommend watching the whole video...

    94. R S K

      These guys know what they are doing

    95. Miro Korinek

      “You’re Oxygen creator” I love that line of the guy so much

    96. Oscar Ayala

      Dow is very well at his job he’s so cool

    97. stevo7770

      Yo, bein on a submarine sounds like a bit of work

    98. Shawn Clarkson

      What are you going to do when you look into the facts and not someone else's theories or so called facts and you find out we don't live on a ball flying through space at over 1 million mph and around the sun at 666000mph and spinning at 1,000mph and going through the milky way at 500.000mph 😆? You honestly put all your time into that lie? I'd look into other facts sir. Best to you.

    99. Shawn Clarkson

      Either a liar or not smart.

    100. David Eddy

      I wasn't expecting how low tech everything would be...analog controls, burning the candles. Oh yea our O2 system is down. No problem we'll just burn these candles we can't put out if something goes wrong.
