Thanks for considering it!

    • How to consistently beat the ever changing algorithm? Avoid the algorithm. Genius (every day).

    • S R B No it makes super sense/ ...solid fueled

    • S R B Sounded like "Lawny"///

    • S R B Try putting some pitch on the outlets / in the valve / and even make the part longer / ....🤚...past ,the tear drop/ oh wow super charged with compressed air // /////and ironically/ it could be / combined ,(sort of/) with that membrane/ and your electrodes// ///

    • Thank you for the video, so interesting to me. Didn't know exactly how this worked, never actually thought about it. Amazing engineering.

  • I'd love to work on one of those ships tbh.

  • The like belgian actually prick because tune pathomorphologically frighten modulo a nonchalant recess. pretty, old hawk

  • The heavenly heavy hellish raven certainly ignore because okra relatedly consist despite a unique rooster. nimble, first rectangle

  • 8:25 Someone shops at Target.

  • This is a dope video!crazy to think how you pulled the strings to see all this.

  • whys he calling a sub a boat?

  • what about the MEA smell on sailors clothes?

  • Plan a tree in the submarine, it’ll convert Co2 into Oxygen.

  • Hey Destin, do you know if they use the hydrogen from the electrolysis for fuel porpuses?

  • My guess for the pre boiler is that the heat differential is too great under pressure that if they introduced the heavy ema it would take too long to reach pressure/gas state given the size and space allotted to the equipment. Also, listening on the elliptical with my Raycon E55's and they really are great.

  • Good Vid. It was nice to see the places I have stood many times before once again.

  • oorah

  • 4:36 "Oh, yeah, not going that way with those weirdos."

  • Don't get lithium hydroxide wet though...

    • Hmm. So THAT'S how you make chlorine gas.

  • Could we use photosynthesis to freshen the air? plants or plankton in pipes or whatever. or some non plant based photo synthesizer panels on walls.

  • Plz make a trip to the moon and make this type of series!!!

  • Deadass thought he was holding a Kit Kat bar on the thumbnail lol

  • Class D fire?!? Holy cow! If that ever happened to our airplanes brakes the fix was to push the whole plane overboard!!

  • Just put some plants in the submarine smh

  • If would be funny if this guy was a Chinese spy ever 😂

  • Can we talk about that sweater he was wearing, dude he looking rad

  • I believe the rocket above the map is attempting to relocate to another room. 🤔 Great video and beautiful puppy. 👍

  • Great video. Thank you.

  • Was there a movie recently where the sub blew up because someone dropping one of those candles in the flooded water .

  • The forbidden lean

  • 6.09 thats the look you make when your learning stuff that interests you .

  • ⭐⭐⭐⭐⭐👍 fascinating!! Big respect to all ppl contributing in all this science!!

  • Mechanically reverse osmosis is not that complicated, but the chemical process for deionization is. *disclaimer, I don’t always know what I’m talking about.🤣

  • @SmartEveryDay, why do we have those chains barricades around when they're about to light the candles?

  • Hmm. So THAT'S how you make chlorine gas.

  • They breath in their farts dumdums. Of course they won't run out of air, submarine people like beans.

  • Destin is about the most handsome man ever in a blue/white farm hat. Destin in a neon orange beanie makes me...uncomfortable.

  • I think I always assumed that CO2 scrubbers separated the carbon from the O2 and released the O2 to be used again

  • Submarines are pretty much the same as being on a space ship. These guys are badass.

  • Totally fascinating technology. This is the first submarine video of yours I have watched and it is super-cool to see this. I am in awe of how young the vessel's crew are. Mad respect!

    • @SmarterEveryDay Completely understand that! I know several veterans myself from earlier times, who are greatly wise from their experiences. As an aside note, working in the Oil & Gas and maritime industries; I see a lot of very bright younger people as well. Complete respect and wish all our younger generation possessed this type of knowledge and experience. Our country would be so much better off!

    • Very smart, and very professional. If I had a business that was hiring, I'd be seeking out veterans.

  • Air scrubbers are awesome! And air candles?! Great episode👍 ⭐️⭐️⭐️⭐️⭐️

  • The guys on these subs are a special breed. Not a job everyone can do. Hats off

  • Giving up secrets here. "Dumping Hydrogen" out into the sea can maybe be picked up from an enemy sub using some sort of "sniffer" of it's own.

  • NIN 15:00 Now I know how they came up with their name.

  • From a laymen's point of view, his shipmates in the video seem a bit nervous or something else is going on. That is a nuclear submarine, there is a lot of high-tech there. Be careful what you release to our-adversaries.

  • " I would have killed everybody on the boat and I *DO* want to do that"

  • Hashtag just buy a bunch of plants and keep them on board with you. lol.

  • How many of those oxygen candles does a sub carry? Those things are HUGE and they go through a lot of them during a day... Where in the sub do they store all of them??

  • Sometimes I forget that nuclear subs might be interesting to people because of how long I was on subs when I was in the navy, my first thought when I saw the title was everyone knows that why is there a video about it 😂

  • When are we going to mars ?

  • Lol I work on a 688 sub like this, cool vid. It is different working in these "cool" places, but ya know, it's nice to see people interested in the science behind subs. I am a nuke so if I were around, you would hear me make depressing jokes and joke about the small amount of folds in people's brains... not that I have any folds :l

  • So how's it done? Cba to watch 30 minutes for a 30 second explanation

  • Hmmm I just thought the Sub has gills like fishes so it can breath under water.

  • 22:46 Who even uses such low quality ice in 2021? We are living in the future, good people, and in the future we can create crystal clear ice. There is NO reason whatsoever to use cloudy ice to cool a drink in 2021. Where did he even get an ice-machine that produces such low quality product? I mean: one, the ice is opaque (causing a reduced cooling-to-watering-down ratio) and two, the ice is some sort of sausage-shape instead of crisp cubes (causing a visually sub-par drink presentation). It is 2021, humans. We need to up our game! Crystal clear perfect cubes or bust. I hope I never again see cloudy ice-sausages illustrating “ice” in a NOlong-video. It should at least be marked as “viewer discretion advised”, or more reasonably “this has been identified as disturbing content - do you wish to proceed?”.

  • 13:34 I like how he pointed the flash light at the face of the guy when hes talking

  • For how long is the lithium hydroxide membrane effective?

  • That sounds frightening. A fire that creates it's own oxygen to burn. Oooof.

  • Your Life sustained by Enlisted Crewman that know their mission.. You don't need an engineer to stay alive.

  • TL; DW Submarines have gills

  • I hope some day in the near future I’ll see you making a video from space

  • the oxygen has to be mixed with other inert nitrogen... pure oxygen is bad for ya... over time you can get cancers.... it has to be dilute to be safer... not to mention that pure oxygen is very flammable, and in a sub, there are things that can create sparks...

  • Just bring a lot of plants with you

  • Everything is so old-school.

  • I wonder if you think a contact could be in the shadow zone - you could use some kind of very sensitive hydrogen detector to see hydrogen being released from a sub due to the electrolysis on board - or a sensitive CO2 sensor to see where there's more of that than there should be... but they're probably released in bursts so you could never get a constant position... or something... loving this series!!

  • Every one knows there's a little tube that floats on top of the water. It's been top secret for years.

  • Its a pleasure to see professionals at work. and a really interesting class.

  • Guy at 4:46: "nope"

  • what does a submarine smell like?

  • Lowest O2 I have personally seen is 14.8%, what is yours?

  • great vid w/ further explanation + drawings, ty :)

  • 10:26 Give that guy some props. He brought hair paste with him, to have presentable hair in the sub at all time.

  • Boopersnoot! LOVE it! :D

  • Very cool. These sailors are impressive.

  • We don't run out of air because we subscribed, liked and commented on another Smarter everyday video.

  • Just put a bunch of plants on board because they breath in carbon dioxide and breath out oxygen lol I wish

  • I dunno why, but I giggled at the idea of silent CO2 farts into the waterm. Esp. given how imporant it is, the more silent you make the farts, the more deadly you are.

  • I've been waiting for more submarine videos! When I was little I wanted to be a firetruck or a submarine. Yes, the vehicles, not the person who operates them.

  • Even you an Engineer looked totally confused.

  • How many candles does a sub like that carry? Must be at least a few hundred

  • I love his child like qualities but he’s also so intelligent and it’s very awesome to watch and hear all his questions and get good answers!

  • I have my coveralls wrapped up in plastic bags to preserve the smell. Makes for a great smell and tell.

  • can raycons pair to two different phones at the same time?

  • We had OBA's (Oxygen breathing apparatus) for going into smoke filled compartments while fighting fires. I believe that It is the same principle on a smaller scale. It has been 50 years ago so I don't know if they still use them. i was in aviation.

  • The inside of the sub looks like a basement filled with 1980s technology lol

  • oo look its Austin Evans lol

  • The unique steel optimally sneeze because stew significantly lick up a testy meteorology. bashful, soggy sailboat

  • always wondered that

  • I’m just waiting for you to get your fish. You’re already there.

  • Preheating fluid is a common motif with boiler systems. It's very efficient to add a bit of heat to inline feed lines.

  • What was he saying? DOW?

  • He referred to two adjectives to describe Anime. He said, RICH anime and he said LEAN Anime... LEAN anime is something like Boku no Pico?

  • I had a friend that worked at the portsmouth naval shipyard on the reactors. he used to tap hydrogen off the reactor, put it in a trashbag, tie it off and attack a tinfoil hatch cover to it. then he'd let it go. the local air force base would send out interceptors to figure out what these weird radar reflections were..strong when the foil was facing the radar, nothing when edge on. they never found anything and the people at the shipyard had a good laugh over it...

  • Apollo 13

  • So cool that the Navy allowed you access to the ship for this. Really interesting.

  • love this series!! the bestest

  • This is high confidential material, now exposed to the world, especially the enemies of US.

  • The heat exchanger preheats the "Rich" MEA with the "Lean" MEA to save energy.

  • The O2 generator with the amine scrubber. Mmmmm.. smells like home

  • We call it the bomb.

  • Made to destroy humanity. The ultimate weapon of mass destruction. Waaaa? Didn't the US start a war because. Culture of death. Do a show about what drives the US death culture

  • 8:00 Caaaarllll that kills people

  • ok fine there was 999 dislikes i had to do it...

  • R/O units in shaft alley ports side

  • Did we just learned how to maybe you know get rid of a lousy spouse with sea water and some wires? How traceable that would be? Asking for a friend.
