@Stan Ervin Simple answer. The Chinese actually tried this exact experiment on the dark side of the moon in recent years with complete failure. Other similar experiments are being done on the space station with some success, but sunlight is still necessary. Some micro organisms were tested with success, but that information is apparently not available to the public. The idea is reasonable until put into reality. All known oxygen producing plant life (including algae) sufficient for human breathing require some form of sunlight in their photosynthetic process for oxygen to be produced. Submarines have been in existence since the Civil war, if there was a way to utilize plants in some form or other I'm sure the scientific community would be celebrating it right now. The Mars missions depend on such a discovery. There are multiple test facilities around the world challenging people to survive in the most inhospitable environments in preparation for the Mars missions and oxygen generation is the number one priority, water is second, and food, survivability along with many other situations follow in priority after that. In this instance there is overwhelming evidence in the proof of concept phase to eliminate that particular possibility, at least for now. I agree that there is always new information developing and the idea is absolutely reasonable to continue research because perhaps someone will indeed discover the missing ingredient. I actually grow, propagate, graft, and merge different species of plants and trees. Trying to maintain these plants in their optimal environment is challenging enough, imagine the types of modification required to sustain them without those systems. I am sure some of those modifications are probably happening on the station. The purpose is to go beyond the information we already have and explore new possibilities. I think the plant and algae ideas have huge merit; however, there are significant setbacks because with reduced sunlight oxygen production is reduced and toxicity is increased. The unknown is where the real possibilities are just waiting to be discovered.

@Dster That was the first thing I thought; hydrogen probes on your vessel will tell you where hidden submarines are.

@SmarterEveryDay You may want to do some research into Raycon. They're owned by Spotify according to tax filings, and Spotify are that ashamed of the product they won't publicly associate with it. Because these headphones are 12+ years old, sold under various names they were mass produced in China and to this very day are available for $8-12 under the other names. Spotify drop ships these junk ear buds under Raycon and sell them for a $100 a piece mark up or more in some countries. They are not a good product. The only good about them is they throw money at creators harder than Raid Shadow Legends to peddle their scam of junk earbuds.

@SmarterEveryDay How can you not know what a sniffer or an oxygen candle is? Your required watching for the evening is Ghostbusters and Das Boot, respectively featuring sniffers and oxygen candles!

@Gw Builder Rather sure that algae is an adequate producer of oxygen. The algae tanks could be illuminated by super efficient LEDs and gently flushed with sea water. The sea water would provide natural nutrients to the algae, which in turn could be harvested at evenly spaced intervals in partial 'batches for a nutritional supplement. Just an idea. Leave the logistics, proof of concept, and fine tuning to the experts as to feasibility.

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-"

Oh my god

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?

Man, its 3 AM here in India and I loved watching this video. Amazing piece of information. Hats off to the people on board the submarine as well.

in world war II they most certainly ran out of air.

How fortunate that you ran into your own dog.

So how was this done years ago before smart computers? Did they have to surface every now and then to pump in fresh air?

Genuinely very interesting. Thanks Destin.

iranian navy watching and taking notes

i thought they just put a plant in there

🔥🎥

Wtf Dustin, you lit a fire on a submarine....

Awesome only thing is we call them ships not boats lol

4:56 the facial expression is amazing

Can anybody tell me isn't hydrogen flammable so do they get rid of it after electrolysis 🤔

yeah, we pump it overboard through a diffuser to quietly release it into the ocean.

Nato strap, I like your style 😎

Okay so where's the navy barrel at? ;)

What lovely people. Really interesting.

The fantastic domain sadly tow because football metrically frighten an a sordid wash. nappy, nutritious south korea

Awesome. Learnt a lot! Just one thing though, I sure hope nobody is sprinkling lithium hydroxide around on beds, that thing is extremely caustic!

Mind Blown.

There was a British sub under the arctic doing Arctic Ice research when there was an accident with these candles. There was an explosion/fire almost killing everyone on board.

That is how those ice caps on poles are capt. Simple: put cool guys into submarine, send them to the pole. Admire those people.

The underwater tube of SCIENCE!
