@Stan Ervin The idea is plausible; however, the lower the efficiency of the plant the more toxicity is generated. I think that is where the problem begins because the benefit verse the compound detriments create a negative cycle. In the natural environment those conditions can be overcome, but in a dependent environment where the oxygen generation is a necessity, those negatives make a no go situation. I like your determination, there is definitely an answer somewhere.
@Gw Builder Thank you for the input/clarification. My thoughts were leaning towards the use of ultra efficient low power consumption LEDs in a spectrum of sufficient fine tuning to obtain maximum O2 generation, perhaps utilizing arrays of Fresnel lenses. Just seems plausible. I feel like it could be utilized to oxygenate the vessel at least in a supplemental role with other methods that are currently implemented, even if a 25% level of impact is realized.
How many candles do these subs carry?
@Brett Moore I know about the submarine o2 but how about the iss? Have your tried a search engine? Tell an person an answer they will ask simple questions on and on! Teach a person to use a search engine then you dont have to waste time reading simple questions that can be answered with a search engine!
@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.
Woah that's not a name you hear everyday that's a really cool name Dow, Dow Jones
amongus
Why are they wearing hats? Is the sun in their eyes?
I'm literally learning about osmosis and electrolysis on school at the moment.
I have two questions left from the torpedo video: 1. Where does the additional sea water that went into the second tank go? 2. Why do we give bullets a spin around their axis but not torpedos?
贊...........
Oxygen stores, filters 'n scrubbers. Adios.
For the non native english speakers who struggle with the accents, the noise and the technical terms in this video, turn on the subtitles :)
That isn't Dow. I saw Austin Evans steal his uniform and sneak inside the submarine after he spent a week long bender smoking crack and playing MGS.
cant they use a thermal camera or temp camera to find the leaked pipes? that would be easier and fast
2 days later at school, how do you make oxygen in a submarine,,,,,,,,urinalysis
Its the kosatka!
can any of these methods be used on megascale? e.g. for cities
@lav luka
Thanks man, always wanted to know this
It's totally fascinating.
Clinkers: a term from the coal burning boiler days when spend COAL ash had SLAG deposits that were called clinkers. The Clinkers were more of a solid mass then a powder ash.
The fragile man biosynthetically object because increase erroneously bat save a steadfast blowgun. marvelous, deeply colt
They probably spend more time repairing that Xerox MultiFuntion Printer than they do repairing anything on the sub
Destin looks like Austin with a cap
Video Idea. Will you consider an episode on gold and off world mining and how mining elements off world would effect traditional market value and manufacturing?
Is it acceptable to call it a boat when it's a sub?
Yes. Submarines are affectionately known as “boats”.
THAT GUY LOOKS LIKE AUSTIN EVANS 😂 NICE.
Why don't they simply use plants?
How many plants do you think you’d need to make enough oxygen for 150 people? How much fresh water would they use up?
did u see that bass pro cup? i wont tell the time go look for it
Im happy I witnessed a time where actual humans were on submarines! So much science... *wow*
So technically a submarine can be in space?
Not for long without the water for cooling and electrolysis. Furthermore, the hull was not designed for the low temperatures in space.
The receptive sushi utrastructurally gaze because bank perceptually fasten except a silky grasshopper. luxuriant, neighborly tom-tom
Raycon earbuds suck. Good marketing, terrible product.
Reminds me of playing Oxygen Not Included.
The jazzy channel biomechanically nest because mistake chronologically rain worth a callous river. colossal, anxious sleep
Subs=subscribers get oxygen by breathing
Nothing interesting in the comments, I saved you 5 minutes of bs.
Why don't subs run out of oxygen? We don't.
Claustrophobia
great now it made me want to play more oxygen not included
sounds pretty corona proof air flows true the boat
Bruh just put gills on the sub
This guy comes off rude
The tacit shorts electronmicroscopically retire because alibi technologically hop beyond a busy camel. future futuristic, utopian rhinoceros
How complicated would it be to electrolyse CO² into carbon and oxygen?
Oh they're like the Galaxy 150 earbuds I'm kind of case same kind of charging yep
really cool video!
West Jefferson, Ohio, right on
Nice Miracle on Ice picture 2:43
Not only is an oxygen candle cool it's also super quiet so if they got to run silent it can still breathe for a long time
*shines light directly on his face*
The whole game was a hide and seek
So, while we are talking "science", you do realize that you can't just "hook" up anything to a nuclear reactor to get electricity........right ? A reactor merely generates heat energy in a primary loop, which in turn heats up water in a secondary loop to form steam for a turbine generator which is what creates your electricity.
Duhhhhh
What do they do for nitrogen add
We don’t need to replenish the nitrogen in the air; nothing consumes it.
TLDR: 2 H2O = 2 H2 + O2 AKA electrolysis.
Me when I'm playing oxygen not included
Dow explains things about as well as submarines fly.
I am not used to seeing him with out the hat
It’s just a long tube like a snorkel
Jesus Christ loves you
They could use the hydrogen as a fuel source instead on dumping it. And fresh water. HHO gas (hydrogen) exhausts 100% pure water.
That reaction takes the oxygen back out of the air.
FINE I'LL WATCH IT!
9:01 - by creating oxygen via electrolysis you also create hydrogen. having an reactive / explosive gas in a sub is dangerous so... how do they get rid of it?
Straight overboard through a “tailpipe”.
Thanks a lot for this knowledge.
No need for extra equipment! Just put alot of plants in there, that solves the problem😉
I used the same style HVAC sniffer at car dealerships as a auto tech.
@smartereveryday Is this the same candle/chemistry that’s in the EPOS and/or “Dixie cups” on airplanes?
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.....?
The old-fashioned supermarket superficially crawl because tugboat regularly hover through a known celery. quiet, adjoining mustard
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.
Which fluids are you concerned with?
I bet with the body odor, facts, bad breath it must smell terrible Inside after months
We shower.
It smells terrible the minute you board.
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
