      PLANTS do both scrubing CO2 and making Oxygen. How many plants would it take to do the same job as these alternatives? How about a comparison video? I'm sure many other fans like me would like to know.

    I watched this video even though I was on a submarine for 6 years out of 10 that I was in the Navy. You did a great job explaining everything. Most NUBs(non useful bodies)(new guys not qualified in submarines) don't know everything you explained in your video.

    Looks like 10-15yr old tech running the sub. I am amazed to see so much of our military equipment with old equipment. The B-52 recently had its end of service date changed. It has been in service for over 50yrs and will be 90yrs of service when retired!! Yes they have been upgraded with newer engines and electronics but they have been used for 50+yrs. Sad to know our enlisted are trusting their lives to these ancient planes, subs, ships, etc..

    I'm gonna guess electrolysis of water to h2 and o2. Edit: dynamite on that hit. Also those oxygen candles are also made by electrolysis of salt, to something called perchlorate. Edit again: never mind, it's chlorate. Same thing more or less. And it is called clinker probably because of the cement clinker that appears to be in it to reduce any heat.

    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.

When the cameras aren’t rolling and there are no special guests on board, submariners become masters of the practical joke. We definitely find ways to create entertainment for sure.
