      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.

    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.

      Maybe while the camera was rolling. LoL. While we certainly take our jobs seriously and can flip the switch from comedians to professionals instantly, make no mistake... 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. You become brothers in the most prolific sense of the word. You will never find a better friend than a submariner.
