    • @Ahmad the newb By everybody in the sub.

    • THEY DONT MAKE OXYGEN!

    • 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

  • This was way more complicated than I wanted it to be. All of these guys are sooo intelligent. Mad respect to them. Thank you for the excellent video.

  • just put a plant and light, thank me later

  • If you got smarter everyday, you would not believe that a lunar lander ever landed on the moon.

  • isn't cams just to detect fires ;) it is kinda to shutdown vents ... to stop fires and in a bad case get some people choking ... casualties like that are the worst I guess

  • That’s cool i worked at an oil field Amine plant. We use it to remove H2S and CO2 out of the natural gas. I never knew that had one on a submarine. Crazy.

  • I was surprised when the guy said about the solidified ash left behind "they call them clinkers, I don't know why" it's because sometimes when conditions are right in a wood stove some of the ash almost glassifies and the chunks clink in the bucket when you clean out the ash. Really cool, I've heard about oxygen candles but never saw one in action.

  • E-5 mafia 🤙🏼

  • The candle striker is a Nine inch nail? Metal.

  • answering questions I didn't even think of; excellent channel!

  • We do not breath oxygen but air , 78% nitrogen , 21% oxygen , 1% other gases. Medical oxygen, 99% oxygen, is however considered as a drug or pharmaceutical product .

  • The malicious second cumulatively love because credit visually analyse within a short brochure. flawless, left trick

  • In the construction world it is a common thing for most people to say driving on frost causes it to freeze deeper into the ground. Would love to know if driving on it is the direct cause or if compaction of soil lowering the r value is the cause for it to go deeper?

  • Think of the pre heater for the MEA as a progressive heater that allows the mixture to come up to temp faster.

  • So many uses for 9 inch nails haha

  • If I had to guess, the pre-heater before the MEA boiler is to heat the MEA faster so less energy can be used in the boiler section, which might also save time. Because the liquid is moving through the heated pipe section, they can make use of convection and not have to wait on the convection flow within the tank.

  • Class Delta Fire.. Makes its own oxygen.. burns underwater.. Yeah it's .. neigh impossible to really put those out.

  • yo ! could I get one of those in my apt please ! this is here to show rich people how to oxygenate their bunkers just. before they nuke us. nice.

  • Thanks for the information I always thought subs had an iron lung

  • Pay close attention. Dow is the smartest guy on the ship.

  • (15:00) Nuclear Sub's can't run without 9 inch nails? EXCELLENT ! *diddleedoodiddleedoodiddleedoo!

  • I love watching and learning all the wicked coolness you teach!!!--- But I still feel the Franks and Beans of me😉🇺🇲👍👍 LOVE YOUR CHANNEL...

  • Giving away our secrets

  • So how do they get rid of hydrogen gas?

  • Destin is for sure a spy.

  • Not sure why I'm here. I was just moved to working on nuclear subs in the shipyard, why am I looking at them when I'm home. :o I blame your sultry, excited-to-learn voice, Destin.

  • its crazy that those candles were used in WW2 u-boats and im assuming other subs and its still used today, wild.

  • It's called a clinker because The word was passed on from UK submariners - original clinker bricks are bricks of clay made kinda shiny brittle and/or vitrified during a firing that exposes the brick to very excessive heat. Real/actual building clinkers are/were commonly used in the UK for building homes, to add historic looking appeal. People still use them to build homes that they want that certain aesthetic - it (more) often does from people using reclaimed clinkers now, as they aren't made very often anymore..... Phew, that's probably a bit too much info. But there you go, in short: a clinker is just a brick exposed to very very high heat.

  • So why don't they use a couple plants and shine some light on them? They tried it in a russian closed atmospherics experiment and the problem was the plants grew and quickly produced too much O2, causing a fire hazard, so they had to start burning plants to remove some of the excess O2. But with some good controls and experienced operators it should be perfectly feasible.

  • Can’t you just take the oxygen from the water

  • Why is this a half-hour long video

  • Dow doesn't seem to like talking much... Getting info from him is almost akin to pulling teeth!

  • i noticed you seemed a bit confused as to why the mea system used a preheater. I am fairly certain it has to do with gas retention. Hotter liquids retain less gasses than cooler ones.

  • "Why don't subs run out of air" 😳😳😳😳😳😳😳😳😳😳😳

  • Go navy

  • I have a better idea. Long tube. You’re welcome

  • Dow is from Southern Ohio. That part of the world seems to have very little annunciation. I work in that area quite a bit and it takes a good deal of time to pick out the dialect. I hear what he is saying as words but cannot discern where one word starts and ends. Dustin says "say it slower"..."no slower" and you still cannot pick it out...lol wicked smaaaart kid though

  • Better living thru chemistry

  • I always like your videos!

  • And just a few years a go a Submariner went to prison for taking a few unclassified photos.

    • Steve, you have a good point. The Sailor should be pardoned.

  • Finally another video from this series. Cool stuff :)

  • You got to go on a an operation sub. Way cool.

  • The spicy diploma virtually divide because font histochemically glue per a naive clef. plant, harmonious shoe

  • I can't even imagine a submarine crew with only women. I can't imagine how they would live in there for months, they would go crazy I think. Because there is no social aspect to this life, its just wake up do your practical job, repeat. I might be wrong of course

  • Prediction before I watch the video: starting with H2O2 and breaking it down to H20 and O2. Edit: I didn't think of electrolysis, and I didn't even know oxygen candles existed.

  • Recycling farts ♻️

  • Honors to the Navy Sub Guys! Thanks.

  • The late impulse immuhistochemically change because property currently irritate via a acid eyeliner. bouncy, friendly trunk

  • How long can you use the water to produce oxygen? What is done with the water afterwards.

  • clinker is term of making coke :or stony matter fused together, great video

  • you should do a video of UFOs and the reverse engineering of them?

  • The rough chocolate impressively possess because armadillo perplexingly obtain until a optimal population. dapper, thoughtful bugle

  • Can you please sell 6 of these to Australia, we order 6 but will take something like 30years to get them. From the France, bad deal.

  • did anyone else catch to pause blooper near the end at 27:27 - 27:29 watch the rocket over his shoulder at top right , can tell he paused, one of a few spots i noticed

  • Thank you for the detailed subtitles! Lip reading can be extremely difficult in changing lighting conditions.

  • I met a woman in college that worked on a submarine. She was a hoot to be around & the class loved her. When we all met, someone asked why she came to a community college. She said "I like the people, I like learning & it's really affordable."

  • Wow they use Nine Inch Nails to light candles when they're low on oxygen. Metal AF.

  • 22:33 Seriously, nobody is talking about that perfect pour? The bubbles man.

  • That aint the A-gang i remember. Ring the bell they said.

  • It's almost Rocket sceince😆🤣😅

  • As another great man of science says, "Science rules."

  • That screen reminds me of one of the few times I got to work in a pre 2000 dev environment. I love minimalist programming. The results are instant.

  • Clinker is probably a reference to the slag you get when turning ore into metal.

  • I bet you those are called clinkers because they are similar to the clinkers blacksmiths make when burning coke or coal as fuel in a forge. They look so much like giant cylindrical versions of the clinkers that come from forges.

  • CAMS tech knowledge: CAMS runs by mass spectrometry and infrared absorption, the best way to explain it is like a coin sorter.

  • 2:49 That's what the c in cams stand for...

  • "Im from ohio" "Oh."

  • Beans last night. Check methane levels.

  • The witty stew corroboratively nail because parentheses bacteriologically unlock a a few fierce author. milky, plastic whiskey

  • So we really need to light the candles because we are getting low on oxygen. *continues to interview*

  • i'd love to see a video about submarine communications. Radio and wireless in the water. You could make a video about that

  • A little over emphasis on breathing out CO2 at the beginning. Still 16% of exhaled air is O2 vs inhaled of 21%

  • Were running low on oxygen we gotta burn this candle Dustin: Oh hey can I interview you guys for a sec

  • As someone who has never served, I love that "politeness" is part of their training, they are just so friendly it's awesome ::)

  • I think the "preheating function" is just a heat exchanger with the output of the boiler stripper. Take the energy out of the lean MEA to better condense it and put in the rich MEA that you're about to boil. Save some time, save some energy loss.

  • liked for princess boopersnoot

  • You have such great energy. Love all you do!

  • Chlorine gas. "Carl that kills people."

  • As hvac mechanics we use a similar leak finder but much more handheld version

  • Now why don't people apply this type of technology to help climate change? If this works in enclosed area's, use it for factories, filters in vents etc....

  • I'm 65 and when I was in my 20's we had an oxy welder, a cheap one lol, that had a canister that you had to light a pellet to use for brazing. Now I know how it worked.

  • I got a good chuckle when he said the oxygen generator was "down." I spent 3 years on a boat and not once did we ever operate that piece of equipment. It's nickname was "the bomb" due to the fact that it generates hydrogen gas and can be extremely dangerous. When we went on mission and would stay underwater most of the time, we'd just load up on oxygen candles and burn them as necessary. It was not uncommon for oxygen to drop to around 17%, which makes you constantly tired no matter how much sleep you've gotten. The other thing is that clean, potable water is at a premium on a submarine. Our distiller could provide 10k gallons per day (if the operator knows what they're doing, if they weren't very proficient then significantly less). That's for the entire boat: drinking, washing dishes, laundry, showers, etc. We'd have to constantly remind people to limit their water use so that we didn't run out. It would make little sense to waste water on making oxygen when you can just burn a candle. Oh, and amine? It gets everywhere. Go up to any AC vent in the engineroom and you'll notice a slight drip of an oily substance. That's amine. It will funk your clothes up for weeks after, even with repeated washing.

  • i hear the soil on mars is full of perchlorate might be an easy way to make oxygen for astronauts on mars but...a class D fire on mars is also probably really bad lol

  • Bad gas. Could you find the leak? 😂🤣

  • FRIGGIN AWESOME

  • The MEA being processed is similar to a LiBr absorption chiller that uses steam or hot water to boil the H2O (which is the refrigerant) out of the bromide solution and repeats the cycle. This chiller also runs in a vacuum.

  • Imagine bein' aboard a nuke fast attack sewerpipe 54 yrs ago without all the super duper modern tech of today....Similar tech back then....We never ran out of O2.....Still here at 75..... arrrrr ;o)

  • Great, the subs are carbonating our sea water.

  • He said two at a time maximizes O2 output.. obviously that's true per minute, but did he mean overall output? Does the Oxygen in the candle bond with another molecule creating a waste bi-produce or the like which is reduced when another nearby candle is also consuming the incidental molecule?

  • When I was a young kid, I took my Snapciruits kit and put each end into a cup of saltwater in an attempt to produce hydrogen. Thankfully, I didn't poison myself, but one of the ends of the extenders turned bright green, like the Statue of Liberty, and the other turned bright orange, like unoxidized copper.

  • I suspect the paper like covers over the ends of the candles were to reduce the chance the candles ignite due to jostling during transit / storage. Great video.. I'm always thinking about how I can engineer 0 emission's sustainable environments, and it's always useful to watch how the old hands go about things :-)

  • "Clinkers" are depositis of creosote that build up in wood/coal stoves/furnaces. They caused issues an they looked like those spent oxygen candles I am guessing old school sub guys nicknamed them clinkers after they're burnt cause they look like "clinkers"

  • How come they don't use plants to help the process?

  • "so this is in the middle of the boat?" Sure, if you're a coner. Too bad they couldn't see the oxygen bleed back in shaft alley, or the CO burners. Another way to regulate the atmosphere is the obvious way. Ventilate at snorkel depth

  • 5:35 ALL THE SNIFFS love it

  • Does the submarine have a... SNATCH BLOCK??!!

  • Ever wonder how the emergency oxygen is supplied on a passenger aircraft? Tah Dah!!!!

  • Man i love to watch your every single video.. you are amazing..❤❤❤ I love science and you're making it way more exciting by your videos... love you man..

  • You don't get smarter every day. You become more knowledgeable every day through learning. Smart means intelligence and that cannot be learned.

  • 12:04 "Rock'n'Roll, like Marty McFly =)))
