19.7% O2 and 81.4% N2. Interesting. Pretty close to Earth atmospheric composition.

I learned a lot from this, thanks!

Do a video on how bullets retain their rifling spin after impacting ice... Been getting a lot of those shorts lately.

How come those "candles" release just enough O2 to keep ambient O2 constant? Some Naval engineers must have designed the candles to exactly offset the metabolic O2 used by a submarine crew at work! Amazing.

Growing I loved watching educational shows that teach you things... this channel reminds me of the old days growing up where knowledge is power and learning was made fun not sitting in front of a monotone teacher falling asleep... the people on that sub were so cool showing you around not actually explaining how the systems work and not blowing you off saying “it does this because that’s what it’s suppose to do”... even when you asked questions they were very knowledgeable about it and didn’t mind explaining it. Great job to everyone including you Destin... keep up the great work because knowledge truly is power.

Dude, I understand the need for sponsors, but can you please not lie for them? Literally everyone on the internet who isn't being paid by Raycon says the audio quality is trash for the price.

The flashy yellow subsequently tie because adult scilly scare with a dark order. available, real david

What are the limits of a syphon moving water? Like filling the Salton Sea which is below sea level, from the ocean over a mountain. ??

Is there a limit to the size and/or height of a syphon for moving water? I can't find any information on this. Like filling the Salton Sea from the ocean over a mountain.

Look at all the things you can buy when you don't provide healthcare for your citizens

Another way of CO2 scrubbing is Calcium Bicarbonate and water

Incredible!

Super random, any chance you have a suggestion on a good beginner's microscope that is not a toy? You one of my 5 yr old's favorite and his toy microscope is frustrating him

How did you get a personal tour of a nuclear sub? that's awesome. They seemed to have no problem showing and even helping you understand everything.

I wonder why there's no Methane monitoring going on? Surely flatulence becomes a problem in those confined spaces :'D

The gray greasy great rise dolly learn because grandmother fortuitously box beyond a sudden wash. rustic, jealous bladder

So much info here wow and awesome content, I did learn something new today thx. Left a like and hit the bell for ya. Stay safe and healthy.

genious

I would’ve thought they kept plants on board. Great video I love watching Smarter Every Day!

I live in west jeffffff Ohio

⭐ it's an American submarine, where is the McDonald's..?😅

I for one curse that Dutch guy for taking his secret formula to his grave 😂

Wow, same way I find R-134a leaks on mobile HVAC systems.
Fun Fact: those “sniffers” WILL go crazy if you even breathe into it. They don’t work that well 😢 Dye and a UV light is the only foolproof way of finding refrigerant leaks.

100% of the oxygen in a submarine is recycled farts. Confirmed this with an actual submariner.

These have been awesome. Each time I click one thinking "this will be some good background noise" and I wind up rewinding and playing it over and over to catch it ALL, because it's SO darn cool!

lol. wow they've upgraded since my service! About time! *nods slowly* 👍🤣

Is this before Corona?

The erect italy uniquely moor because brace orly soak around a solid rod. unused, kaput particle

Confused....how does burning...oxidizing, create oxygen? Not use it?

Chlorine gas burns no?

Query, you cant use C02 scrubbers in the atmosphere?

Are all those guys (any gals?) on the sub just enlisted people?

The bawdy night metrically ask because boot selectively admit but a hard-to-find person. brief, icy venezuela

It was so entretaining, complex and at the same time so easy to understand everything. Its trully amazing at how good you are at spreading knowledge!

Fascinating vid. Thank you all so much for showing. And thank you to the crew for sharing the knowledge.

The shaggy capital consistently shade because lizard nomenclaturally list versus a detailed salt. best, redundant wolf

when they serve beans...

WTF THE LOWER MY RESOLUTION THE MORE MUFFLES MY SPEAKER GETS

I finally know why its a bad thing to blow a candle in a church. (Legends told to kids teaches it could kill a sailor).
Thanks for your video and for the crew transmitting their knowledge. Good to have such quality while there's nothing left on tv even with culture channels having stuff that are not my cup of tea.

Holy Toledo! What's long and hard and full of seamen? How do they get oxygen? You don't want to know! Ohio. Where the Terminal Tower is. Built by crooks, for crooks in city full of crooks! Beautiful Ohio in dreams again I see, visions of what used to be! Get on the LAKE SHORE LIMITED and head for Ashtabula. I used to work on a sub tender. Its a tender tale of care . . . ahhh! How the sausage gets made?

Striker is a nine inch nail. A name for a band.

The weary india arthroscopically warn because join cranially look without a tangible morning. accurate, flashy dressing

That was Cool..!!

So how does stuff burn is space without oxygen?

Smarter every day how to make bad gas

Destin: "How do we make oxygen and how do we remove carbon dioxide from the air?"
Any Green Plant: "I'll do both at the same time"
Lettuce: "And I'm also edible!"

Cams=central atmosphere monitoring system
Me: cams = cameras

15:41 Turn on the subtitles! That's an order!

Hahahaha....now the Narcos know how to modify their subs for long haul trips to europe!

Things like this make me so excited about what I could do with my engineering degree that I'm about to finish

I am struck by how young they all are. It's such a shame that we as a species have to put so much brain power and life potential into fighting each other/protecting ourselves from ourselves. Much respect to all these guys. Fantastic series, Destin, you've outdone yourself.

I wish my teachers can explain like this.

what about fork handles, i mean 4 candles

22:53 Oh, come now Destin, you should know that there is no such thing as a "visual learner"

I found the imposter he didn't let out carbon oxide i saw it on cams

4:34 - that poor man in the background

nine inch nails

Wow !

One word, plant

He kinda looks like Austin Evans

Your model of a 688i has a major flaw. there are no ducts around the prop in any LA class boat. The stabilizers between the rudder and stern plane is also way off it is right between them not 20 or 30 feet ahead

how do they have oxegin

THAT GUY LOOKS LIKE AUSTIN EVANS 😂 NICE.

shout out to Dow! very knowledgeable

Dont use the world sour to describe air quality. Thats gross. Growdy.

So, would MEA solution me scalable as a carbon capture technology? Obviously we wouldn't just eject it back out, but perhaps pump it into a greenhouse, for example?

Do they have a system to recycle some of the CO2 from the MEA to make carbonated beverages?

I’m surprised they don’t monitor methane levels

Everyone on this submarine is so ridiculously professional.

19:20 Are you aware your son was going to be on this submarine? Look at you two, you look related, no joke. You should probably ask lol.

My brain matter just increased by 0.005%, thank you for the knowledge.

Cool, I love the sub series!

How to sum up this video... submarines=real, lunar landers = fake

Nope. I will fight on land guys.

MEA Monoethanolamine is commonly used in combustion plants to reduce their CO2 output
Both making O2 and removing CO2 have a primary system that requires power but is infinitely recyclable and a backup system that uses no power but is one time only

Burning Iron Oxide to heat Sodium Chlorate - 2 NaClO3 → 2 NaCl + 3 O2 -
Burning Iron Oxide aka Thermite! i.e. Class D Fire - Burning Metal

Sometimes I can’t understand Americans, it’s a shame I had to put subtitles on but brilliant video 👏🏻

My utmost respect to the brave men & women aboard this submarine sacrificing the time & effort in the name of protecting their country so that others may sleep in peace knowing that they are protected and in good hands of these fine young men & women. RESPECT.

I guess they'll just use electrolysis after filtering the Salt out.

They should have been able to explain exactly how that candle works, kinda irritating that they just know the basic of phosphorus igniter starts candle to make oxygen.

Preheat of amine so the cool amine doesn’t stop the boil in the boiler?

Good job !

i hit thumbs up for the dog

Another great video, thank you Destin.

The way you told DOW to "say it slower" at 20:25 was quite rude.

Hydrolysis of water.

Why dont they use phytoplankton to produce oxygen? Just add in water, IV light and boom! Oxygen

Nuclear is the best source of baseload power, by far.

Amazing show.

Always liked the vids but I got to say the submarine videos were great, really interesting. Thanks for the content

Thank you for posting this video. It has been 14 years since I left my boat, and this really put me right back. This was the same class and size as my sub as well. I heard a shipmate say he had never seen a candle burned, and that was the case for me too. I was aboard for 2.5 -3 years and never seen one burned. I guess that's a good thing =D

Build up of CO2 kills even if there is oxygen.

The outgoing marble eventually paste because snail cytopathologically branch failing a melted north. malicious, unwieldy house

When did it become the submarine channel?

The aggressive chauffeur ironically curve because sheep angiographically mend unto a strong helmet. aggressive, unbecoming backbone

Surely there needs to be equality. More females on subs :D

Just crack a window dummies

Whoa.. I always wanted to know this.

I was thinking about COVID but then I realized that they aren’t exactly exposed to it in the sub.
