        @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.

      2. Stan Ervin

        @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?

      4. Dan Quayles ITS SPELT POTATOE!

        @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!

      5. Gw Builder

        @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.

    6. JaThe Winner

      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?

    10. Nabman11

      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.

    11. MrFrosty Vlogs

      cant they use a thermal camera or temp camera to find the leaked pipes? that would be easier and fast

      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?

    23. Josemanuel Piceno Vasquez

      Is it acceptable to call it a boat when it's a sub?

      1. Eddie J. G.

        Yes. Submarines are affectionately known as “boats”.

    24. Overdose Tech


    25. Viva Wö

      Why don't they simply use plants?

      1. Eddie J. G.

        How many plants do you think you’d need to make enough oxygen for 150 people? How much fresh water would they use up?

    26. Serial Chiller

      did u see that bass pro cup? i wont tell the time go look for it

    27. DimljenaRiba

      Im happy I witnessed a time where actual humans were on submarines! So much science... *wow*

    28. Themagicphonebooth Q

      So technically a submarine can be in space?

      1. treverios

        Not for long without the water for cooling and electrolysis. Furthermore, the hull was not designed for the low temperatures in space.

      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

      The whole game was a hide and seek

    50. Roger Finch

      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.

      1. Charles Quackenbush.


    51. Dan Lo Fat

      What do they do for nitrogen add

      1. Eddie J. G.

        We don’t need to replenish the nitrogen in the air; nothing consumes it.

    52. KopaZ

      TLDR: 2 H2O = 2 H2 + O2 AKA electrolysis.

    58. founder of coreism

      They could use the hydrogen as a fuel source instead on dumping it. And fresh water. HHO gas (hydrogen) exhausts 100% pure water.

      1. Eddie J. G.

        That reaction takes the oxygen back out of the air.

    59. Skyler Baird


    60. DontRobMe13

      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?

      1. Eddie J. G.

        Straight overboard through a “tailpipe”.

    61. aLiEn

      Thanks a lot for this knowledge.

    62. Toxichammertoe

      No need for extra equipment! Just put alot of plants in there, that solves the problem😉

    63. all the boost

      I used the same style HVAC sniffer at car dealerships as a auto tech.

    64. wolfpackflyboy

      @smartereveryday Is this the same candle/chemistry that’s in the EPOS and/or “Dixie cups” on airplanes?

    65. the Yesinator

      I am smartly dumb.

    66. Maherda Ekananda

      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.....?

    67. ideally CHIC

    68. ScottNJ

      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.

    69. Saintraft

      ahh yes... imagine if we had upgraded nuclear tech instead of abandoning it all these decades... fascinating stuff.

    70. Ck digital The Q of 6th

      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.

    71. Eric Starling

      I'm an ex A-ganger on an 688I boat. This exact boat type he visited. Awesome memories

    72. ʟᴏɴᴇᴠᴇɴᴛʜᴏʀɪᴢᴏɴ

      Does it really take 30mins to explain this?

    74. J Alexander Bill

      shocking lack of comments on Princess Boopersnoot.

    75. goguhu

      Kink is pretty much Dutch for 'brick'. It's the residue ash from burning, hardening into a ... brick.

    76. Bernie Lomax

      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.

    77. Caesar Ong

      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.

    78. Logan Cook

      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.

      1. Eddie J. G.

        Which fluids are you concerned with?

    79. Chuck Whitson

      I bet with the body odor, facts, bad breath it must smell terrible Inside after months

      1. Eddie J. G.

        We shower.

      2. Grampy Meyer

        It smells terrible the minute you board.

      We use sniffers in the oil and gas industry to find gas leaks and other harmful gasses such as H2S and explosive gasses.

    93. newbiekunchannel

      Topic Suggestion!!! "Military MRE" how is made, what is the science behind the calories to an actual soldier is using (carring guns, ammo, supplies)

    94. Eddie

      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.

    95. KodyKK

      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.

    96. Jay Patterson

      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!
