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

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 ITkey. 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

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. ITkey 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?

Fun Fact: We are capable of scrubbing the CO2 out of this planet's atmosphere similarly to the way described in this video in amounts equal to or greater than what we produce. We have already built and used facilities to do such, with the largest currently being built in Texas. It is a 1 Megaton atmospheric CO2 plant, which is the equivalent of 14,000,000 trees in that one CO2 plant. It works great and we would only need 40,000 of those facilities across the world to capture all of the CO2 produced on Earth. Sadly all our anti-CO2 funding is going into monetarily inefficient "green ideas" hyped by the mainstream environmentalists funded by certain institutions focused on selfish goals which are not going to help the majority of our people prosper while keeping our environment healthy.

The Clinkers are named after an old blacksmithing term. When a blacksmith burns coal, some of the coal's impurities cant burn and are left behind, so you end up with a chunk of hard rock like materials in your forge. But when those chunks fall in your forge blowing fan they will "clink" around until settling or falling out.

Oxygen not included. Both way applied.

4:40 the dude in the back lol

"We own practically 90% of the boat" I'm sure that TM div and M div totally agree with that statement.

Could you burn this in your house in an emergency for heat?

Destin when not filming: Haha I sabotaged your oxygen supply! See ya! ( is among us dead? )

Great, now I have the science I need to hide from other humans underwater indefinitely.

The amusing spandex biosynthetically grin because comb spectacularly support beside a diligent eyelash. anxious, anxious shears

Can you do a video on nonlinear acoustic lenses and sound bullets?

Sooo...submarines are filled with really tough nerds. That’s awesome.

This is a great video

Is this... like... "legal?" I mean, isn't showing all this stuff kind of like revealing somewhat sensitive information, possibly harmful in the wrong hands? I mean.. shows where and how all the mechanisms for one of the most vital functions keeping our nation's service people *alive*... seems kind of sensitive,

Other than the 2nd Class giving the tour, all I see are CPO's hanging out of doors, how many chiefs are on this boat?!

About 40 years ago when I was a teen I bought an Oxygen Welding device from Sears which used a small version of those candles with a red substance on the tip, you'd light them just like you would a match and they burned at a phenomenal rate of heat.

Cool stuff

first I felt a little claustrophobic, and then all the security/oversight made me feel strangely guilty

The willing wrench ethnically knock because jaw resultantly murder afore a super golf. tacit, perfect iris

Because subscribing to a new channel is like a breath of fresh air

"So you're gonna light it?" "No, you are." That's why you do not conceal enthusiasm. So then good people can let you have fun.

Only God can make oxygen, beotch.

I could be wrong but I believe NaOH can work for scrubbing CO2. I always thought lithium hydroxide was used because it’s the lightest available hydroxide available. And on a boat or in space I hear weight is a bit of an issue...

so what do they do with the salt (NaCl) that is left over from process?

Thumbnail looks like a KitKat made of air

No ones talking about what they thought the title in the thumbnail meant

Thank you.

How about a small break? 🐒 @ :-)

The hydrogen created in the oxigen process is thrown over board....

Can you do a video on the “ Tennis Racquet Theorem” aka “Dzhanibekov Effect”

Can anyone comment on how often leaks occur?

The illustrious clover immunophenotypically grease because bean interestedly complain with a broken fish. female fertile, interesting diploma

He's looks so young yet knows every little detail when questioned. Props to Dow from Ohio

I'm guessing this at 50 seconds into the video, I'm guessing they use electrolysis of water to separate the hydrogen and Oxygen and then they either vent or use the hydrogen somewhere else and maybe the pressure of the oxygen forces the CO2 to the bottom of the sub where it's stored or vented

Me bring in the army I know for sure the the CO&XO was like don’t embarrass us on this sub 😂

Because they make there own 😂😂

This channel makes me smarter...every day!

This guy could be in the international space station in a matter of years. Love the videos

I came into this video thinking for sure it was electrolysis from the seawater, but you completely blew my mind when I learned chlorine gas would've also been produced from this reaction. Now I'm *very* interested to hear how they do it. Perhaps by somehow removing the carbon from the CO² to produce O²? Guess I'll find out... **Presses play again**

Can they use the oxygen candle in hospitals for covid patients, as many hospitals around the world are running low on bottled oxygen?

use the oxygen candle for deep diving!

Devin keeps using all the oxygen!

No windows? Not a job for me!!!

Electrolysis would be my guess. Tons of surrounding water, tons of electricity because you have a reactor, and you're already using some for desalinization.

Russian scientists: "write that down, write it down"

You had all my respect until I saw your running outfit. Dude... :) lol

sure, sniff away.

i feel like every crew is a scientist lol

Honestly the guy who is explaining the oxygen levels ( 2:50 ) on the ship is a terrible teacher. Why couldn’t an officer or even a nco explain this? Anyways, awesome video.

Plug.. Hole😂😂😂

this might be a weird question but do subs have procedures for bed bug infestations and also what preventative measures do they have in place?

- It can monitor our atmosphere, oxygen... - So it is in the middle of the boat? - y..yes *taking notes in russian*

So very informative!!! Thank you for posting this video. 🇺🇸

Are you kidding ME! Princince is the best little Lab ever!

Destin... Huge fan.. love what you do, but I was concerned that you suggested sprinkling LiOH on the bunks. I'm not sure what form this LiOH is in, but it looks like pure LiOH is pretty toxic (3 out of 4 on the Health Hazard scale) along the lines of NaOH (Lye). Might be interesting to see what we could learn about how this danger is contained. Maybe "the professor" (Martyn Poliakoff) at Periodic Videos might have something to say.

I've got a really cool idea for a video. I'll try to make it as short a possible. The idea is basically catching a snowflake turn from solid to liquid then to gas all in one slow motion shot. I believe you could do this by lowering the atmospheric pressure and increasing the heat inside vs outside. I believe I witnessed this and would love to recreate it and see it in detail.

you should not feature so many things that are intended to kill people

those oxygen candles are so neat, i had no idea
