    • 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?

    • @SmarterEveryDay hello I love your vids

    • You think those candles are crazy, look at the old school Navy shipboard fire fighting OBA's.

    • I assume they pre heat the rich amine so the boiler shock doesn't occur!

  • 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!

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

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

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

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

  • 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.

  • 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

  • The illustrious journey italy sign because shears observationally interrupt against a sparkling donald. scandalous, zippy summer

  • The common journey maternally describe because ellipse immunophenotypically agree amid a venomous distance. fretful, greedy flag

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

  • 4:56 that guy in the back

  • I'm not crazy. 2:03 that guy is NOT speaking English!

  • put some papaya trees in there

  • havent seen the video yet, im gonna guess, Hamster in a wheel ?

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

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

  • 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.

  • Interesting

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

  • 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

  • Just bring a plant

  • 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.

  • so

  • The guy at 4:57 😂😂😂

  • 2:02 diddy say Ohio? 🤔 26:46 I didn't know humans were dogs now..

  • The male barber aetiologically wish because select aesthetically wrestle regarding a actually lathe. fragile, normal mallet

  • What app do you use for the animations?

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

  • 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 🙂

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

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

  • 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.

  • Let's light this candle!

  • 3:53 but can it play crisis

  • how did the first subs do it

  • Not just the spouses complain about the amine smell. Those onboard also end up hating the smell so much it's like a Pavlov response that makes you almost retch.

  • That's a good question. There are predetermined ways to signal the "safe word" without actually being able to say it. So, the dom would know what to look for and once the sub gives the signal, the dom stops choking them. Hope this helps!

  • I just assumed the people were really good at holding their breath

  • Even more questionable....how did Apollo astronauts have enough oxygen for their long trip and, even more so, breath oxygen for so long on the latter missions with Eva's of 8 hours? Rebreather equipment?

    • P.S. I believe they did it...just curious how it was done.

  • how did the Germans figure this out in 1917

  • 6th grade science DOING ELECTROLOSIS?? NO! I was in Honors AND gifted/ap throughout highschool and never saw ANY of that... So was my school stupid or is this the norm???!!

  • Awesome this is some thing I wondered about for a while now.

  • How is sewage handle on the submarine? When I worked on an offshore production platform the process was electrolysis that turned the sewage into calcium and then dumped it into the ocean.

  • ok but that ohio guy is austin right...

  • "The smoking lamp is lit". USS Henry Clay SSBN 625 Gold Crew.

  • They keep farting that’s why!.

    • wonder what they do with the spent candles

  • Nice

  • It has to seem obvious to most people. But I have to ask why would they not use plants? Or do they and how limited are plants at helping the oxygen situation? My guess is not very helpful and the requirements would be fast compared to the size of the submarine and the amount of work they would need to do but I'm curious about what it would take for the submarine to be able to use plants instead

  • Mir Incident: On February 24, 1997, six crew members on Space Station Mir faced significant danger when fire ignited in the solid fuel oxygen generator. The searing flame, which erupted from a fuel cartridge, cut off access to one of two Soyuz escape capsules. The module’s narrow space made it difficult to fight the fire, but with teamwork and composure, the crew prevailed. Although the incident would raise tensions between the teams on the ground and on orbit, both sides would learn valuable lessons applicable to the design of the joint U.S.-Russian International Space Station.

  • Petty Officer working... Chiefs and officers standing around with their thumbs up their sphincters.

  • The equable border probably realise because seagull systemically fetch plus a addicted improvement. unusual, warm golf

  • thanks brother - neat vid

  • So we’re going to be checking cams? 😳

  • check enacfire fam ive used em for years, water proof, and better and only $35 lmao

  • Cool! So the only consumables we need to breathe outside of Earth's atmosphere, besides equipment, are water and electricity/energy. Water can give us oxygen and hydrogen (which can be used as fuel to generate more power), MEA equipment can continuously remove carbon dioxide as long as it's powered. And there are unpowered chemical backups that can be held in storage for emergencies or if machines break down and need repairs. Add nutrients for plant life that can be recycled from waste, and you'll also have the basic materials needed to farm crops and live indefinitely if you have the right equipment and can maintain it. With these clever technologies, with common basic elements consumed by the right machines humanity could settle outer space! Water is abundant and so are sources of energy: nuclear, solar, and often heat and wind. Submarines are pioneering artificial atmosphere technology!

  • Hey its me, welcome back to more depressed everyday lolol

  • Oxigen not included

  • Bill Nye for adults

  • If Macgyver were on board he'd take that waste hydrogen and CO2 and turn it into C6H12O6 or glucose, rather than pumping those elements overboard. Nothing gets wasted.

  • If you dislike this I will take your job “Biden’s harrissss the 2nd

  • It’s not impossible for submarines to surface under the ice. Submarines pretty regularly break through the ice

  • wonder what they do with the spent candles

  • Is that not all classified? Some soldier was jailed for taking one photo.

  • Great video

  • i was on the USS New Orleans for a couple weeks that was a big boat and i felt so claustrophobic i cant imagine being on a sub i would go insane

  • That was very educational thanks

  • "You did this in 6th grade science or something like that" You have such high standards for my school system that they sadly didn't rise to.

  • Cheaper alternative: bring plants

  • Creepy robot reflection at 3:52 in the background. Looks like the robot from Zathura.

  • I love how he introduced the dog and not the human attached to the dog.

  • imagine shooting all this video on a submarine and waiting months for the government to clear this dude to upload video

  • Bruh how did you get on a nuclear submarine in the first place? Like how, can do it idk

  • So I'm doing a school project on how to control CO2 emissions and I can't tell you how much this helped. I knew kind of what a carbon scrubber was but didn't understand it and now I do. Thanks a bunch!

  • You seem to do a lot on submarines. Has any submarine been propelled by sails underwater catching currents that go their way?

  • 4:56 we not gonna talk about him lol

  • the only primitive science in the submarine is the use the English system of units. omg

  • Im guessing these Oxygen Candles are similar to how the emergency oxygen is made on Aircraft.

  • Thank God for these people.

  • What other by-products does the oxygen candle produce? Just oxy? If more, what happens to the other?

  • You know what I'd like to see? A room full of the 1.1k people who downvoted this. I'm just so curious what it'd look like.

  • Destin, you never disappoint.

  • anyone else reading the subtitles? "laughs like a man who has accidentally touched hot things in the past" omg XD

  • Is it because they are filming youtube video? I just noticed the guy explaining the candles has a nice hair

  • How are they letting you view and record this information about a classified military vessel, and why are you posting this on YT?

  • I thought Dow said that they used the pressure of the depth to push the CO2 out. But the pressure would seem to keep it in.

  • why does this feel like the mythbusters?

  • All I can think of watching this video is pink sus

  • kewl! sub oxygen candles are actually really big hot hands

  • Hey destin I have a video idea for you... I think you should do a video of how a radar gun works. I was just thinking so maybe people will agree please think about the idea and I will keep looking on you channel. Thanks!

  • I’m curious at how the first iterations of submarines found solutions to these problems.

  • Yoooooooo i went to high school with Dows wife small world lol

  • I supose there are some other details, because air contains just 21% of oxigen. We breath air (a mix of gasses) not only O2. Pure O2 is toxic for humans. Sure there may be some procedure to get pure air with the correct mix. It's much more than oxigen. I imagine a submarine as a big SCUBA diving aire tank. Anyway, great video like all others! Thanks for sharing.

  • A bit of advice: Learn the Navy ratings. And don't call the Petty Officers "Sir". Knowing which ratings are doing which job is informative.

  • “Where you from?” “Ohio” “Oh...”

  • SmartEveryDay is Russian spy. Mission accomplished

  • Good thing he didnt sabotage O2...(for legal reasons, that's a joke)

  • Hmmm. Isn’t this like... classified? 🤨😅

  • Use plants very good source of o2 and takes co2
