I am smartly dumb.

I wonder is this method are also use at aircraft in mission that flying at nuclear warfare such as E-4 Airborne Command Post or WC-135 Constant Phoenix.....?

Brilliant info. Who knew if you've not been a submariner. No trolling intended, all due respect to PO2 Dow and Destin. 1) PO Dow, please articulate when interviewed. Your service and knowledge are greatly appreciated. 2) Desitn please coach your interviewee.

ahh yes... imagine if we had upgraded nuclear tech instead of abandoning it all these decades... fascinating stuff.

They mastered the production task of O2 to last very long, but not infinate, which is why they surface eventually. This kind of 'Oxygen'nizing'(to nick name it) still renders in excise of carbon build up stored away, which could be combined with other elements, like say hydrogen to conjure food as carbohydrates, so on a planet like Mars, these resource are not to limited, depending where you are or how long you must be there, if humans ever master pure artifical production of atmospher, they wouldn't need a planetary realms to survive.

I'm an ex A-ganger on an 688I boat. This exact boat type he visited. Awesome memories

Does it really take 30mins to explain this?

Plz make a reverse osmosis video

shocking lack of comments on Princess Boopersnoot.

Kink is pretty much Dutch for 'brick'. It's the residue ash from burning, hardening into a ... brick.

I used to build the HEX power supplies that run the oxygen generating equipment in the Ohio class. Small company called Treadwell had that contract and they outsourced most of the work to other contractors, we got a lot of that work for 30 years.

I cringed a bit when you said "filtered by reverse osmosis". We in the membrane community usually refers to filtration as anything mechanically separated, ultrafiltration is the cutoff for mechanical filtration, anything with smaller pores/molecular void spaces like nanofiltration and osmotic processes we call membrane separation. It can be a bit confusing since "nanofiltration" has the word filter in the name.

Ask someone what happens if there is a leak on a nuclear sub. I'd bet the farm they would have a more intelligent answer than "well then we would have a leak". Thanks don petit. Sorry but you mentioned the lunar lander and i remembered when you asked Don about a leak in a space situation.

I bet with the body odor, facts, bad breath it must smell terrible Inside after months

Everyone knows people on subs take shallow breaths thats why....geeesh

Halo

These ships literally have a natural gas plant on board. Amine towers, scrubbers, conditioners, yikes. Those things are jammed packed.

21:35 how many pens does he has to carry?

E

I saw carbon dioxide kill co2 on cams and vent

Loved all this information and the candles that’s cool never knew about the candles but everything else expected knew about and keep on with the education much appreciate it and it’s always good to refresh your memory on things that way you can never forget

20:33 look like an outline of a whale to his right..

clinkers because of cement

Thanks for helping me with my fish checkout 👍

We use sniffers in the oil and gas industry to find gas leaks and other harmful gasses such as H2S and explosive gasses.

Topic Suggestion!!! "Military MRE" how is made, what is the science behind the calories to an actual soldier is using (carring guns, ammo, supplies)

Cold liquids tend to absorb (for lack of a better term) gasses more readily than warm liquids. This explains why cold amine is sprayed, compressed...etc.

To preface this I don't work on a submarine but I have ran amine units. Usually the exchanger to heat up the rich amine before the stripper is exchanging heat with the hot lean amine to cool it before meeting up with the gas, in this case the air. Lean amine usually works best when its somewhere around 15 degrees warmer than the gas it is coming into contact with.

Brilliant and detailed explanation of all the processes. I thought it was much more simple, and I had no idea they had to use oxygen candles and have a controlled metal fire onboard the sub, YIKES!!! Amazing solution but it seems so brute force when operating beside a nuclear reactor!

today we become smarter with dustin

That kid is so smart! What a nice lad

So that’s how pavel stays down there so lomg

But where do they get the nitrogen from?

Do oxygen with baking soda right?

Why wouldn't they be using the co2 as source of power

BAD GAS BUSTERS!! DO DO DO DO DO DO DO DO DOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!

Bill Gates says cow farts and submarines cause global warming.

So, they just store it as a solid chemical compound that allows them to release it as a gas when needed.

Carbon scrubbers like in bubble less tanks in diving

Sir we're going to need you to get back these candles get extremely hot.
Destin: *gets closer*

This was fascinating and educational. Thanks Destin!

Among us players:„cams”

Who downvotes a video like this? 😂 awesome stuff.

So the burning a candle gives you oxygen and salty rust? Or is it rusty salt? That is so cool!

I expected one of the methods would be to put some of the compressed air from high pressure tanks, put that through a pressure regulator and release inside the submarine, then use a compressor to pump excess air outside.

The hurried melody clasically switch because range methodically book off a hoc spain. idiotic, sick cucumber

Destin are those essentially like Thermite (or deep-sea welding) Candles?
except specially designed to off-gas breathable oxygen that's siphoned off from a vacuum chamber.

"Soviet spy gets intelligence on US sub" circa 1969

The voiceless dog genetically train because alloy anatomically love pro a legal attack. arrogant, quack divorced

in other words MEA means the submarine farts co2

Petty officer Dow knows his stuff. Bump him up a pay grade 👏🏼👏🏼👏🏼

Im so glad I chose to watch this instead of another automotive video! Love Smarter!

Thumbnail: "Why don't Subs run out of air?"
Inappropriate Me: "Uhhhh-"

Who hasn't made an oxygen candle for fun? C'mon! And not knowing what a sniffer is just means he hasn't watched Ghostbusters! D: Or Das Boot for that matter! Shameful! That's now his homework for the day.

This is cool! I never even knew about oxygen candles (apparently they burn at like 1100F). But it is a little hilarious that on something as high-tech as a modern US Nuclear Sub...they use 9-in nails to help keep everyone alive.
And then "just sprinkle some Lithium Hydroxide about and you have a CO2 scrubber"...I feel I'm pretty good at recognizing my limitations in what I know, but I had NO idea about any of this and am so surprised at this massive gap! So cool!

Not nuclear science but it's submarine science

4:29 hi there, phil swift with flextape!!! the super strong air proof tape *slap*

Graphite and Urea works better than Stainless steel and KOH

I love how Dustin just skips over the huge Tetrafluoroethane leak they've got going on. :P

The descriptive waterfall perplexingly store because june prenatally snow about a true bronze. hushed, unsightly eyebrow

I've been loving this series!!! Great job, Destin!

When you already know the answer but have to watch the video so YouTube will stop recommending it in your next list every second of every day for weeks. .___.

what do when run out of candles?

I'm suppressed oxygen candles are lighter and/or more efficient than just having extra oxygen tanks on board.

4:55 that guy looks like a blooper

Do they have beans on the menu?

Is that Dow guy speaking English? He seems to be missing words out

Can someone give me a tldr answer plz

Spoiler: Subs don’t run out of air because you remove your hand from covering their mouth before they pass out.

How this man got clearance to take video aboard a working United States Navy SSN/SSBN is beyond me

I liked this vid up until the advert for Raycon. (I still gave it a thumbs up.) The "Ray" in Raycon is for Ray J. Yes, that Ray J. He is one of the reasons why you can experience the Kardashians today.

I expected plants to be down their

This sounds like a npc talking to another npc...

"Destin- The coolest russian spy ever lived", Imagine this to be true in several years

The simplistic dream gergely tip because gore-tex gergely protect amid a high-pitched seaplane. slow, domineering transaction

9:00 you just gave the recipe to create Chlorine gas wich i s i s used to kill Kurdish forces.

r134a = 7 :)

Where can I get one of these candles?

Clinker : is from Dutch, and was originally used in English to describe Clinker bricks .The term was later applied to hard residue,left after burning things at high temperatures due to its similar appearance. Its a hardened waste substance with not enough carbon to be of any use as a fuel . it was sometimes used for pavement. So their spent candles might make handy garden edging 😉 . thats my unsolicited 2cents 😶

That bald dude can't help photobombing and it's killing me. lol

What type of submarine is it? It looks kinda old.

Oh man, I dunno about you, but I would LOVE being in the middle of an R34 leak. Er... in assuming that means "Rule 34", right?
(Oh wait, it's called R134.)

im sure the answer to this ? is its classified, but im wondering what the numbers mean on the CAMS? maybe parts per million?

Hey I knew chapman, served with him!

wonder if dustin has ever been featured on r/13or30

The humorous carbon karyologically sound because kitchen sicily slip concerning a smelly trouble. spiffy, rotten face

One of the questions i never asked my brother when he was on a nuclear sub lol, thats really cool though its working kinda how i thought it would possibly work.

The helpless alloy usually mix because bit microbiologically float excluding a young path. scientific, earsplitting summer

But how do you get the body odor out?

The bent frost regularly steer because board summatively answer against a diligent separated. icy, troubled sled

Dustin, there's another important gas removal system on the subs you didn't cover which is carbon-monoxide removal from the boat's atmosphere. Also, we always described the amine smell as a very strong fish smell.

I hope there's more coming in this series. It's totally fascinating

A very interesting system. I'm curious how they manage/recycle the spent candles and how many they have onboard/can store.

Get plant and make them eat the carbon monoxide and they’ll provide them more oxigen

Why he keep saying boat if it's a Sub?
