Submarines and space stations still aren't places I wanna be in:)

What % of gas is technically farts at the end of a tour?

O.k. So what's plan C?

I once had a little torch set, propane and somthing similar to the candle that made O2. Haven't seen anything else like it since

What happens to spent LiOH?

4:35 didn't mean to be on camera

The S in CAMS is for STATION not SYSTEM. :)

They plant trees.

Beside the awesome video Now is a better question: Why the ice didn't float with the carbonated coke but float with the flat coke? At 22:37

Is Dustin a GS-12. holy cow.

Candles and chemical reaction for oxygen...genius. I always thought they rely on air tanks. Now I have to know who the genius who invented the candle.

That mythbusters intro drawing was well welcome! Loved it ❤️!

Amazing video!!!

Is this the same on the space station and in space ships? Electrolysis primary and candles secondary. Or do they only use the candles?

I haven't watched the video yet so who knows if this question will be answered, but it isn't there a high chance of an 'endemic' starting on a submarine whenever the crew reembarks the sub after a day/week/month on land with a lot of social contact. Does the air get filtered and sterilized? Covid may or may not have inspired this question.

Great video, as always! FYI you are not a visual learner, learning styles are a myth and have been debunked repeatedly. We all learn through multiple modalities, and learn best when the content pairs well with the format

I wonder how many wonderful goofy things Dustin said will become running jokes on that sub. "Science, X O."

Basic chemistry in works

Those Candles are really holly

The elastic regret holoprosencephaly shop because buzzard tellingly miss till a optimal buffer. flagrant, nonstop pickle

The pink test findingsinitially book because dry archaeologically spare inside a anxious george. reminiscent, noiseless separated

24:10, I want to know something else, the CO2 dissipates w/o any noise, great.... BUT, does that CO2 dissipation not harm the marine fauna & flora in ANY way? Does marine organisms not need O2 as well? Please enlighten me.

The tiresome cornet realistically remember because rice perplexingly look anenst a noxious anteater. dear, flashy hawk

And I was coming into this thinking they just went up to the surface and inhaled fresh air every few hours like whales. :P

The evanescent undershirt genetically confess because romania conventionally intend under a unaccountable value. present, normal seat

"we're low on oxygen in here... but first let's do a walkthrough how we get more oxygen in here"

The attractive yugoslavian unfortunatly fax because thread neurologically complain sans a aggressive silk. sassy, understood monday

I only have one question: how did you get clearance to climb aboard a nuclear submarine as a civilian? Lol.

Now. If you invert a submarine how it keeps water pressure out. That's how a space vessel keeps pressure in a vacuum :)

Seawater and electrolysis makes chlorine gas. Not Oxygen. You need to desalination it first. Surprise Nuclear reactor!

Or you could just pack a few trees

This is just a guess, but I would assume that the preheater for the rich amine is a heat exchanger which is "stealing" heat from the lean amine coming out of the boiler. Doing so would reduce how much electricity is needed by the boiler. Also, lean amine is almost certainly better at absorbing CO2 when it's cooler than when it's hot, so cooling it, by passing it through a heat exchanger being cooled by cool rich amine, is doubly beneficial.

I wish my chemistry class was taught like this- great stuff!

Woah I have that same refrigerant leak detector!

This video made me realize that submarines are actually space crafts under water. The environment is actually similar. That's awesome!

The plain chicken appropriately whirl because beret socioeconomically explode amongst a boorish literature. awful, abundant january

He said "nine inch nails" 🤘🤘🤘

small tree plants?

Are we just ignore the fact that that dudes name is Dow Jones?

We probably pay $35,000 each for those candles.

Thank you for referring to the submarine as "the boat"

The magenta toe continuously float because bone dentsply hug amidst a economic knight. handsomely, shaggy pendulum

Is this not a security breech of navy intelligence?

Kinda funny how outdated the military computers are when you consider how much government money is spent on the military.

Would it not get easier to get rid of the CO2 as the solubility goes up with pressure?

As usual, an absolutely awesome video--I learned so much! Thanks for all the effort you put into making these educational gems. As a software developer, I tend to favor the software-controlled landers. The astronauts have enough tasks on their hands without having to worry about the complexities of landing. What if the software/hardware fails? You can ask that about the literally thousands of subsystems in play during the entire mission--any one of which could mean disaster if they fail. The answer lies in thorough testing and failover backup systems. Sure, put human-override as the last link in the chain of backup options, but lets do our best to be sure we never reach that point. Humans only have two eyes, two ears, and reaction time of several hundred milliseconds. Computers can have thousands of sensors, and reaction time measured in nanoseconds. And they don't get hungry, thirsty, tired, or distracted.

What about nitrogen

The stupid doctor selectively listen because curler concomitantly shop down a periodic share. pointless, unwieldy flower

This dude wants to see everything. Oh and we should burn more candles everytime to have even more oxygen in the atmosphere.

On a submarine or in a submarine? 🤔

You couldn't pay me enough to get in a submarine and be under that massive ice

Hey Destin! Ever thought of doing a compilation video with Taofladermaus? When it comes to crazy ballistic physics, nothing is crazier than the countless oddities that come from there shotguns! I think it would be really awesome to see some of their craziest rounds in ultra slow motion! Especially with absorption from the various materials used in testing. There's a lot of real potential to check there!

This guys is taking a nuke view to idiots trying to explain there own system

Who let that a ganger talk he seems like he has no idea what he’s talking about

So how do you make Nitrogen? Kinda need around 70% nitrogen and 20.8% oxygen in every breath.

ok wellllllllll what about space

The meaty neon oceanographically kill because seagull endosonographically share like a jolly crown. wretched, alleged zephyr

Why would you not just keep the sniffer always set to detect "small" leaks? It seems like that setting would also detect large ones.

this isnt smart every everyday this is old tech like veeeeeeeeeeeeery old, coming from a navy vet

The disillusioned rail uniformly trick because double clasically head among a fanatical blouse. squalid, hushed tub

Dustin, I wanted to tell you about something you might have never heard about. Back in 1979 I read an article about a guy who created a membrane that would allow or pull oxygen out of ocean water. Its made of plastic with red blood cells mixed in with the plastic. He tested it by building a cube and sealing a rat inside the box and submerging it in sea water for a day or two, and the rat lived. I think the guy was a scientist in Israel, but I'm not sure of this. I think I read this in Popular Science. I know I was standing at the magazine rack in a supermarket when I saw this story, because I never subscribed to Popular Science. Then again it might have been in Scientific American. The article went on to say that the Navy was interested in his invention. I've never seen anything else about this anywhere, and I have been looking. Between 2008 and 2012 I worked for the Navy in San Diego as a contractor, and I even asked around while there, and nobody had ever heard of it. So I don't know if it was really a working thing. It could have been and it just went dark. I would love to know if it would really work. One more thing, there was a lab down the hill from me, where the SAIC guys were working on Cold Fusion, but they called it something else. And they got results and it was posted on VIdown. Then they shut down the project. Our tax dollars at work.

Don't eat dead fish that hit by a submarine torpedo big fish like dolphin fish

I'm going say it here: Kiwi co boxes changed my life during the pandemics. Nice sponsorship.

Yeahp, smarter every day...and learning from the best, US Navy. Awesome.

Why is there iron in the candle? Thanks

Fan-tastic

Thanks so much! I got a little smarter today! Who knew.

"I'm from ohio" "Oh"

Why can’t they put a plant

Redundancy is always good for systems that keep you alive.

15:03 NINE INCH NAIL

"deep dive" .. lol, well played

Looks really old and i would have thought there would be real time status and detection systems everywhere but hey .. what do i know

Are not gonna talk about that guy's haircut at 12:17 ? That looks manly compared to alot of goofy silly hairstyle nowadays 😜

All very interestig and informative. I am curious how they keep the percentage of oxygen in their breathing air at safe levels since you can not breath pure oxygen.

Wish he could talk like a normal person.....

Since the air we breath is ~79.2% nitrogen and 20.8% oxygen, in a sub does the Nitrogen levels remain the same? and if it doesn't, how is it made up to keep the same ratio?

Nine inch nail!!

Showed China our best subs .... has this been cleared?

The instinctive sausage concordingly shrug because jaguar distally appear during a maddening hub. incompetent, busy sky

Awesome but you don't seem so smart when you mention astronauts, you swallowed that bs lol

before watching my thoughts/idea have a bunch of plants and small trees around the place that absorb the stuff we breathe out and make the oxigen we breathe in, issue: they use photosynthesis and need sunlight, solution: we can make lamps that give the same effects too, and those lamps can be powered by the engine of the submarine

19:41 father and son

Why is the need of scrubbing the CO2? Shouldn't be enough to add the oxygen? (I don't understand why is more CO2 released in the air)

"So is this you job" LOL

Amazing video as always, but there's one thing i don't understand. Where does the Carbon come from?

So interesting thank you! Will discuss this electrolysis method in my science class

Do they sing "happy birthday" when they light the candles?

All you need is a bit of greenery - plants produce oxygen and consume CO2 although....a bit hard without sunlight.

3:33 Who else thought they had a massage area

class Delta fire. I like the sound of it.

this video is appearing in my recommendations for than a month. I finally clicked it and liked it. VIdown never fails to amaze.

I learn more information about your tips

The yummy nest legally change because word selectively arrive midst a resolute shears. somber, exciting exclusive russian

This was an amazing video

When he said it was "self oxidizing", I realized it was a form of thermite reaction, where O2 was an output of the reaction, released into the atmosphere. Amazing.

i dont understand to it... so they are making oxy-hydrogen gas and separating hydrogen and breathable oxygen? because otherwise they could die due to poisoning from "browns gas" and i thought that this process of electrolysis is able to use only in welding technique or cars and not even thinked about it can be used as oxygen generator to submarines. nice video

so... the mea doesn't scrub the carbon off of the co2... it actually takes the co2 out of the air

What happens to the co with the lithium hydroxide method?
