      3. Whogives Afuck

        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.

        What resin and orientation did you use to make the electrolysis thing?

      My takeaway from this video: Princess Boopersnoot Well, you got me to watch your Raycon sponsorship. xD

    12. Brettlaken

      Are todays submarines nearly permanently submerged or do they still spend most of their time at the surface?

    13. Selena Gamya

      Why don't subs run out of air? It's called breathing through your nose.

    14. mugenrios2k

      One of my payloads for ISS is working on a system to scrub CO2 with out consumables (cansters) or the MEA/moving liquids. MEA process can not be used in 0G as the differences in density in the expelled co2 gas and the mea do not allow the co2 to rise out of the suspension. In 0g Buoyancy processing can not be utilized as a key part in separating gasses from liquids.

      I bet the mess hall never serves beans on that boat while the buckeye is burning those candles.

    19. wertewrtwert

      Preheating of the MEA is mostly likely a heat recycle, where the hot lean MEA is used to heat the rich MEA in some heat exchanger. This also effiecently cools the lean MEA, which increase its ability to absorb CO2 since cooler liquids have greater gas solubility.

    20. Richard Lighthouse

      When I read the title, I thought they were using electrolysis to get oxygen and just pump out the co2

    21. rdgk1se3019

      What about Methane?..........human farts.

    22. 288theabe

      26:47 best part of the video 😍😍😍😍😍

    23. Lorentari

      Before anyone says "We should just use CO2 scrubbers to reverse climate change" - CO2 scrubbers takes a LOT of electricity to run. Also, you are just capturing the CO2, not getting rid of it.

      They just roll down their windows..duh

    26. Jacob Moore

      I did electrolysis for a science fair project (testing the effects salt had on speed) and decided to take a sniff of the "oxygen" side, during a run with saltwater. Didn't even clue into the fact that since the house smelled like a pool something might be up. 😬 Glad I had the sense to step outside immediately into the fresh air as my airways drastically restricted! Needless to say, I stopped experimenting for the day!

    27. Nico Plowman

      As a retired U.S. Navy anti-submarine and multi-sensor specialist, I can assure you that all our nuclear subs CAN break through the ice to "get fresh air". Mainly they must have this capability to launch ballistic and guided missiles. They also have the ability to release "sensors/transmitters/receivers" that can break through the ice when necessary. The technology on our newest boats is mind blowing indeed. Just wait until you see the 6th gen fighters and bombers!

    28. gojewla

      I am surprised that electrolysis is fast enough to be practical for something like this.

    30. WD-40

      One can also use Calcium hydroxide a.k.a. slaked lime to absorb CO2. The products of the reaction are Calcium carbonate and a pure water.

    31. Little Prince Mica

      Oh I get to learn of the sn774 I have a toy if it

    32. LoneWolf7878 gmail

      So I'm not that smart 🤔 but what I'm hearing is even though you said many times "light a candle," you mean not just ANY old candle but a special candle that isn't manufactured for public use?

    33. Dom Vasta

      O2 partial pressure of 153 torr is normal where I am, but obviously the ambient pressure on the sub is higher so you'd be aiming for what? 160 torr? 200 torr would be a fire hazard.

    34. Unkle Buh

      My dog is cuter than yours. Jk cute puppers 😂

    35. Nicholas Gworek

      I work on this stuff for a living, developing and testing. Very cool video, well explaining the basics, showing stuff that a lot of people never knew.

    36. iyo8

      What do you do with the leftover Chlorine? Do you have leftover Chlorine?

    37. Stuff152

      Lol easy, just bring some enough small trees and bushes they make oxygen 😎😎

    38. Ole Rasmussen

      My first 2 seconds thinking: Oh, that's really simple Next 2 minutes of thinking: Okay, there are a million problems I can't answer

    39. Vale6332 _

      If we paid only half the attention to our teachers as we pay to this guy we'd probably all be A students.

    40. jin lim

      this is bs... the nuclear reaction with sea water creates oxygen...

    41. L P

      3:00 I was expecting to see the ammunition levels in the UA 571-C Remote Sentry Weapons System :)

    42. zuygj bnsv

      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 🙂

    43. Barry Mantz

      Don't watch the whole video! In Submarines they have a machine who gets the Oxigen out of water! (H2O) End of video!

      1. Barry Mantz

        @zuygj bnsv No, it's not! There never will be an enemy or a spy inside a submarine!

      2. zuygj bnsv

        Basically, a sub is Among Us irl.

    44. Neall Shandler

      What about the nitrogen component that's what we mainly breath.

    45. Etchy

      I was on the 705. Its amazing that nothing much has changed since I left back in 96.

    46. JonoZ

      Right now ALL of the yardbirds are WTF CAMERAS?! NOOOOOOOOO!

    47. larry heath

      With the new Mars rover having the MOXIE to create oxygen from CO2 - if we have the means / science to convert CO2 to Oxygen and have power from Nuclear Reactor of Sub why would they not use a MOXIE to take CO2 and remake Oxygen without having to use these candles.

    48. Clark Sarge

      Our AEOG was also always down. Thank God for O2 candles!

    49. Andrew Bowman

      It's like watching a grown 8 year old...

      Welcome to the US military. I am sure my phone has 100 times more memory than the CAMs system on this $1.5 billion

        But then its probably as robust and reliable asf ... no viruses or hackers

      "that is a very bad thing and it would kill people" but kaaaaarl xD

    55. LuCiF3R_OP

      When I saw the thumbnail I thought the guy on the thumbnail was joel kinnaman 😶

    56. buzz magister

      I always wondered why the crews of subs in films feared seawater getting to touch the batteries . I learned something today .

    57. Super Li李詣超

      Nice painting skills right there, appreciate it

    58. SheddyBear

      I love your videos Destin, but I am put off a bit at the more recent military-centric episodes.

      Hey guys this is Austin!

    61. Nootpocket

      The sable pull conversantly object because pleasure visually happen on a picayune outrigger. wealthy, chunky windshield

    62. Ayoub

      Engage with the woman --- Now that s something

    63. Harshit

      Seriously using Torr as unit of pressure? Didn’t expect this from the navy !!!

    64. Johann Carvalho Melo

      That's so cool ! Nice video

    65. relyk226 notnroht

      Could you imagine when the figure out how to perfect hydrogen engines the sub could run on made energy from the oxygen making.

      1. relyk226 notnroht

        Yeah but the idea is better than just dumping all of it once the concept is more perfected.

      2. Eddie J. G.

        It would be less energy than needed for the oxygen making.

    66. scarlet 001

      why dont u research the raycon product ohhh and can that submarine be applied to underground system like deeper the ground pressure will will high right i guess correct me if im wrong thank u

    67. Marius Tubac

      I have nice content too.

    68. agsn

      how about farting on submarine?

    69. Drain Man

      Just like i remember it.

    70. Black Panther

      Destin could probably pass a sub qual board by

    71. Connor Duffy

      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).

    72. Jackson Mabon

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

    73. Tim Schütze

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

        why? Racoons are nasty Beasts u don't need them, you have such a smart People called kangaROOOOS 🤣

    80. L Acepub

      Genius who ever that founded Candle's Idea for creating pure O² Brilliant

    81. 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?

    82. 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.

    83. Asad Marji

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

    84. Wouter Pomp

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

    85. subcook32

      Candle residue now tracked throughout berthing and crew's mess.

    86. Abdulaziz Gurra

      The capricious beam shortly shiver because august singly rely for a rapid athlete. sincere, satisfying acknowledgment

    87. Tapejara 150

      Dow explained it really good.

    88. Klaus Cottonswab

      He's a spy, now the enemy knows where to strike!

    89. utahraptorfast

      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.

    90. luc-ass Styker

      O2 Has been sabotaged

      Yo but doesn't hydrogen explode?

    95. Gary Schultz

      good show

    96. Stefan Mihai

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

    97. 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..

    100. 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!
