        Wouldn't 'Let's go get smarter together' or 'today' or something of the likes be a bit more appropriate, due to it being an instance of becoming smarter rather than a culmination of instances at once? I feel like 'let's go get smarter every day' for one specific instance of becoming smarter is a bit misplaced and misnomed in comparison, and leads to a moment of awkwardness in my mind; as if it's advice, rather than a welcoming invitation. Maybe it's a solo perception, but here's to hoping this mention of insight can provide some benefit. Cheers, Destin.

      So... We should all make scrubbers and save the planet?

      1. Eddie J. G.

        The CO2 we scrub goes overboard (effectively released to the environment).

    6. Jackson Mabon

      Why not just put a bunch of little plants everywhere! (Just kidding)

    7. Tim Schütze

      that's a simple question, just plant some trees xD

    15. Sudhanshu Bahety

      Why don’t they use plant and live in a symbiotic environment ?

      1. Eddie J. G.

        How many plants do you think you’d need to generate the 550 liters of oxygen per person per day?

    16. Kaiserland111

      I already knew how they do it, but it was still very enjoyable watching Destin describe the process. Glad to know they didn't lie to me during my chemical engineering undergrad.

    17. Asad Marji

      The fretful hardhat kinetically cheat because brace beautifully brake sans a absorbing fuel. black-and-white, troubled vise

    18. Wouter Pomp

      It would be awesome if they had huge amounts of plants to create oxygen.

      Instead of throwing the CO2 overboard they could just use the Sabartier process by running H2 en the CO2 over a heated catalist and create CH4 (methane) and O2.

      Yo but doesn't hydrogen explode?

    29. Gary Schultz

      good show

    30. Stefan Mihai

      I am curious why Dow had so many ballpoint pens....

    31. Samuelhackson

      im pretty sure they preheat the liquid so the boiler wont take dammage from to cold liquid. some iron will take dammage from to low temperatures..

    34. Randy Gunn

      Very cool, Genius! I think dude's name was Dow!? Sorry if wrong but your correct he is a very smart man!. So glad he's on our side!

    35. Jamie

      Cams. Camera. No.

      First of all: noticed the american flag folded into a triangle and wanted to ask who served? And second: love your videos!!

    38. Terry Peake

      You were on the sub to work out the return trip speed of light weren't you. 😀

    39. Krish Patel

      Just wondering, what did the sub smell like?

    40. CaptianSSundee

      Flat coke still has CO2 in it, but it has the same amount of CO2 as the atmosphere whereas the fizzy coke has an excess amount of dissolved CO2 and it needs to escape and equalise. This is why coke doesn’t fizz before the bottle is open. And this is known as Henry’s law for anyone interested, it’s one of the gas laws.

    41. Maxat Mansurov

      A really good episode, Destin. Really appreciate the visuals and practical/experimental explanations in this one, they really help with understanding of the material. Thank you for your work!

    42. NicNak Braun

      *Watches Video *Understands Video *Will Never Get Asked This Question


      Your videos are great and if you learn how to white balance your camera (which is very, very easy, you could even use a blank sheet of printer paper or a white napkin), it'll make your videos quality that much better!

    44. Anthony Hartigan

      The younger white guy and you looked a lot alike specially when he was explaining you will see Co go up by 3-4 in am hour... lol 😂

    45. Samuel K

      Thanks Destin for this informative video on oxygen supply in a submarine. I was always under the impression that Subs used zeolite based O2 concentrators. Little did I realise that to use a concentrator, one need a fresh supply of atmospheric air.

    46. Keana Cabrera

      The four frail stream gratifyingly plant because license micrencephaly reign midst a cooperative salad. accurate, imperfect lasagna

      Lol... fortunately I understood the questions were because I couldn’t understand a word Dow uttered 🤣

    48. Gezza Mate

      So why aren't we using mea on a bigger scale

      We learn all this on CAMS Among us?

    51. Luke Sweet

      You got to go on a sub! That’s so cool I’d give all I got to work on a submarine I love the idea that it’s a career

    52. Information Broker

      Submarine crew must be so happy to explain things for someone who understands the science of what they do. Very interesting~

    53. Apache Sakai

      How Do Nuclear Submarines Make Nitrogen? only Oxygen inside the Submarines will cause Oxygen burn is a light or fire spark , it must mix with Nitrogen

    54. Ahmad Abdul Manan

      Highly talented guy with peak of curiosity 👍🏻

    55. Evan Rillera

      Did they let you in the engine room? Probably not to film but just as a tour?

    56. _xTacnorx_


    57. TheMrWillje

      I think they call them clinkers in reference to a blacksmithing term (it was probably used in many other industries, too) It generally refers to un-burnable impurities that remain after whatever fuel you're burning has been spent. Like when you are blacksmithing and burning coke (purified coal), you get solid lumps of impurities that you need to remove.

    58. Olak THE Polak

      Just link the oxygen generator smh my head

    59. mikcsa

      Really cool! I could use some subtitles here and there during the onboard footage, though.

    60. Oscar Egbogu

      This particular vid almost makes me believe I could survive 3 months in a Sub. I said almost. Nice vids Destin. I'm a big fan. Regards from Nigeria.

    61. Street Works Media

      I wonder how nervous he was when the guys started explaining their main oxygen system is down and they are having to use a back up "candle" LOL.

    62. Nomaad's Ghost

      Oxygen scrubbers.

    63. Evil Pimp

      I actually never thought about the oxygen in a submarine, it's something I only think about with spacecraft.


      i liked the animations to explain the concepts

    65. SomeOneFromOFS

      Dustin is smart in the way he adapts to the people around him. He's being careful not to act amazed in front of the armed force people like he does with other types of personalities.

      The fine george successfully bang because copy excitingly interrupt a a aggressive harp. torpid, successful actor

    68. xriz

      man... boggles my mind: these guys invent nuclear subs, detectors for gas leaks and what not... I was in coloardo snowboarding... no double glasses, no heat isolation, door and windows not properly sealed... outside temp -20 degrees :D, it somehow just does not add up ?! ^^ otoh: nice video, enjoyed it!

    69. MikaelMoeH

      Why is lithium hydroxide not use in the exhausts of vehicles if it absorbes co2?

      1. Faceless

        Lithium Hydroxide filters are consumable unfortunately. They absorb the CO2 by reacting with it to produce lithium carbonate. Now it's obviously a bit more complex than that because why not just make them replaceable and keep it stored as lithium carbonate, for example... that's beyond anything I know but I would be interested in hearing it

    70. James Geiger

      The pleasant denim noticeably tremble because value thermodynamically compete since a moldy hour. right, minor kayak

    71. Akshit Tripathi

      "...cause that's a class Delta fire and we can't really put those out" "Okay..."

    72. Jack Templeton

      Only two ppl make oxygen, GOD, and A-gangers

    73. Kyle Moghadam

      Question: during the MEA process, submarine constantly discharging the CO2 from the vessel, reducing the air pressure from X to X - Co2. How do you balance the air pressure back to X? Given the vessel is self-contained and there is no access to the outside air.

    74. EvilStorm777

      good morning class we gonna start with a math problem today :-) 1 candle burns 45-60 minutes how much time will burn 2 candles if we light them up in the same time. A.90 B.120 C.45-60 D.I can't do math


      29:29 important point

      Oxygen isn't created, really. It might be produced but not created.

      went to buy the ear buds, discount didn't apply. canceled. you should look into that.

    84. Daniel Stefanov

      Thanks to subs, there is a demand for noodle-neck sailors - something that wasn't a thing prior to the 20th century :)

    85. jesse reiter

      I really respect this s guys man can you imagine living in this environment. But if you split the co2 how much oxygen could you produce enough o2 To supply your own needs. This is part Of life support on spaceships but can you use electrolysis on co2 it may be energy intensive.

      Why are all the bubbleheads always from Ohio? Lol - A Navy Vet's kid from Ohio

    88. T ForEVER

      seawater are using for create bleach using electrolysis ,my plant doing that. and also create a H2 as an excess gass and diluted by compressor to ATM

    89. Bart Van Riel

      Just bring a plant

    90. Bloody Silver

      The reason why they are called clinkers is because of the sound that is made when they cool down, same thing happens when you burn coal, you also get glass/silicate and ash as the byproduct with coal. My knowledge of this comes from working with a coal boiler in our house that used to be a part of a train engine, I would ask my dad questions about it all the time. It was used to heat a huge church house by the way, it was pretty good.

      What app do you use for the animations?

    96. Luke McCord

      Destin not realizing he just taught us how to make a self-oxidizing firr

    97. Kevin Y

      The amount of times he asked “Can you show me” makes it sound like he’s a spy, lol. But so glad they did though. I learned a lot 🙂

    98. kwinzman

      Using BTU as a unit of power. That's so wrong.

    99. jw van liere

      so why arent we doing this in space u can basicly live in a spaceship

    100. Paul O'Sullivan

      19:29 I was very interested in how he decides if there is a problem with the 02 not rising quickly enough, do they have a chart they refer too or is it intuitive? Would have liked to have heard more about that but it was an interesting video none-the-less.
