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 thought he was going to say the headphones button Is so cool because they pause the music and turn up the outside noise to hear people better, not just to pause music like my $40cdn Poms that are a knockoff of Airbuds that are a knockoff of airpods lol but good enough.

too bad there's no way to effectively store the hydrogen produced during electrolysis on submarines. After spending all that energy to produce it, it would be nice to be able to store it for use as fuel or propellant

I am an ex-submariner from the 80s (SSN 678). It's amazing that so little has changed as far as O2 generation. Thanks for the video series. It brought back many memories.

Awesome video as always! The preheating stage at 23:37 with the MEA solution must be to increase the overall efficiency of the final heating stage, in a sub every space must the carefully design to ensure minimum space is occupied, taking advantage of the higher contact area of the pipes and preheating the solution during pumping to the final stage is cleaver and rises the overall efficiency of the process.

If I had to guess [prior to watching.] it's some combination of "compressed air tank storage, Rebreather style recirculation, or, my favorite option, Electrolysis based O2 production from water.

Hah. so Electrolysis was the one he talked about. and...I hadn't strongly considered the chlorine gas but..i had sort of mentally touched on "probably would purify it first, cause...sea water has fish poo and stuff. sooo...partial credit.

Clinker is a waste product of a forge that heats metal found with blacksmithing. Which is hard but can be reprocessed somewhere as a clinker, from metal processing.

Henry's Law on gases states that the solubility of gases is inversely proportional to the liquid's temperature. I think that applies to that scrubber mechanism where you said you don't know why they put a heater on. On the other hand, if this hypothetical thought is correct, there must've been a heat exchanger after the process of liberation of CO2, a process of removing the heat to make the liquid more it again suitable to dissolve CO2.

Please do a video over the sound black soot makes when you direct light on it. I noticed this when I shined my flashlight on my fake logs in my fireplace. I can’t find a good explanation for this. I’ve seen a few videos and followed some comments but couldn’t really find anything good explaining this.

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.
