They call the burnt candle a clinker because it resembles the burnt coal when forging. In the bottom of the forge, there is a trap, so the gas line doesn't get clogged. And it clinks when cleaning the trap. So, the debris is called clinkers. Amazing as usual. Thanks for taking us along.

[@havenstapleton1450]

This was my exact thought! ‘Somebody’s been a trainer before!’

[@scissorbeaksgames8208]

Submarine service is a training environment. Formal training is held weekly for every division. Informal training is held daily on every watch. Chiefs train their group, the more qualified watchstanders within that group then train everyone else who comes to them for assistance. It is very much hands on training but just as much of it is theoretical in nature. Everyone learns to teach their job to the new unqualified guys coming aboard. Every individual develops into a trainer/teacher. The more we train our shipmates to do their job, the more opportunity we have to learn more advanced tasks. The civilian job sector could learn a lot from this method.

[@havenstapleton1450]

Having transitioned to the civilian workforce, I couldn’t agree more. I was happy to have a good job but not pleased to have very little guidance for complex tasks.

The reason why they are called clinkers is because of the sound that is made when they cool down, same thing happens when you burn coal, you also get glass/silicate and ash as the byproduct with coal.

Yes, the other stuff like weapons and controls are super cool, but it's the details of what you need to survive is even more important and interesting. As someone who plans on going to Mars and will be older (so a one-way trip), I've been studying stuff like this this so that I can perform multiple roles while there. If I don't get to go to Mars, this is still super interesting because this is what's NECESSARY to do anything else on the boat. I hope you got to film a ton of other "mundane" things on the boat because this is the real meat of what makes these super complicated machines work. Like the kitchen stuff you did, mundane compared to nuclear tech but super cool because everyday people can relate to them and we all do it, just in a different way.

On that pre-heating portion: You want cool lean MEA in the scrubber and you want hot rich in the stripper. So you could either put a refrigerator or radiator behind the stripper and waste all the heat you put into the MEA or you can use a heat exchanger. With a heat exchanger you transfer the hear from the rich MEA you want to cool down into the lean MEA you want to heat up. This reduces the need to put additional energy into the system for heating and cooling.

[@Obi117kh]

But why does it have to be cool and lean and hot and rich?

[@Willcol100]

@@Obi117kh CO2 is soluble in cool basic solutions and when it is dissolved it becomes a carbonate ion. MEA is a base so when solutions of it are cold and carbonate free they can collect CO2 from even from CO2 depleted sources such as breathable air. Carbonate ions become unstable at high temperature decomposing to produce pure CO2 gas which can be ejected from the submarine. Ergo you want it cool for the part of the cycle when it is absorbing CO2 and thus going from lean to rich and hot when you want it to emit CO2 gas to reduce the richness and return to being lean. You have to go through this cycle as MEA has a maximum capacity for CO2 absorption before it won't absorb more. Note the same cyclical reaction can be done with the Lithium Hydroxide however were as hot for MEA is 150-200 C hot for Lithium hydroxide/carbonate is 1300-1400 C.

@@reallynotbob6 everyone on the submarine that wears dolphins has qualified submarines. To qualify you have to have general knowledge of all systems on the boat. You need to be able to draw them. Supply power to them (fire). Isolate and cross-connect them. Any person if they had to should be able to save the boat (subs traditionally are called boats not ships). Everyone onboard is also trained in firefighting, damage control and firearms. Not enough room to carry people who only have 1 job.

I'm enjoying this video series more than I enjoy Netflix.

[@robotsix6268]

Of course you do.

[@kylancook3477]

Its getting easier to dislike netflix...

[@muzaaaaak]

Real people. Not actors. And we don’t have to listen to anyone’s political views.

[@jamessutter6700]

So say we all..

Netflix = Dumber Everyday

15:37 "don't actually touch it" . That sudden increase in the tempo of his speech shows a tremendous ammount of experience and professionalism. Respect.

[@CyberSystemOverload]

Can we all just take a moment and give a huge shout out to Dow. This young guy is in charge of monitoring the life support systems that keep the Navy warriors alive. He is proud of what he does. One day he might well command a boat. Respect from the UK.

[@kencrawford6494]

All the sailors we saw seemed great and very eager to teach the science and show off the tech they were allowed to. I can see why any Navy would do this, it's probably a great recruiting tool and makes them look great

Dow Selby was one of my father's great uncles. Dow Selby owned and operated a Blacksmith shop in Dunsmuir, California Siskiyou County during late 1800's through the early to mid 1940's

Missed the "Destin Starts a Fire on a Nuclear Submarine" clickbait title.

[@ireallyreallyhategoogle]

It wouldn't even have been clickbait since it's true. He started the worse possible kind of fire, one that can't be put out.

[@boblaw4483]

I'm happy he's not click baiting me on learning videos

[@lovablesnowman]

"Small arson prank on a nuclear submarine gone wrong! (I nearly killed over 200 people!) NOT CLICKBAIT

[@ireallyreallyhategoogle]

@@lovablesnowman Now THAT would be clickbait.

"I lit two huge candles on a submarine low on oxygen and then this happened"

[@benstanfill363]

The way they talk about a delta force is hilarious. "that's one the fire you don't want" "you don't want to leave that open, that's a delta fire and we can't... Put those out". Fantastic series, I just love every episode and so much of each episode. There's no boring parts.

Delta = Class "D"

I failed school big time and math was my worst subject and I still struggle today. However watching this episode of making oxygen I knew straight away with your experiment with the Salt sea water what the outcome would be before you said it. This is an example of the various things that in my school days I failed at, I strived to learn something new. I have been in vocational positions my teachers said I would never be in and I have raised a family (to Grandkids now) kept food on the table and have learned new things. This why I had to place a comment on this channel that... These clips and explanations opens up an amazing wealth of learning, also confidence boosting. Thanks to KZbin and your sponsors it opens corridors and also makes over feel that they have the brain to learn. Last comment was 2 years ago so hope this is still being monitored and thank you for your clips.
