CHLORINE GAS & SUBMARINES: MUST KNOW (be Smarter) Since world war ONE (the German submariners were more likely to be killed by CL gas than anything else. ANY leakage of SEA Water inside would end up in the BATTERY Banks Compartments. which ALWAYS were at the bottom of ship. Their weight also had the function of being a BALAST. and thus, The FLOOD of Sea water would submerge the Batteries(100s). the electrical shorts would immediately create immense levels of Chlorine gas. the gas would immediately invade the whole SUB and killed them, So they never knew what happened afterwards, whether the ship hit the bottom of the sea, Imploded or surfaced. They were all DEAD.

@David Scott So what has Taiwan or China got to do with the American Navy? Why do you think it does? It's not simple, it's arrogant. This is exactly why America has become the most despised nation on earth. If you travel outside of the US, have you not noticed this. You have a great military, but a third world health service. It's a shame, you don't understand this.

@Carol Cassidy Isn't it simple? They use their power to control others, and they are taking over Taiwan. So the more power they get the more land they're going to take.

Take water in, make oxygen out of it, humans transform oxygen in carbon dioxide, filter it, take carbon dioxide out. You are just like a tree that needs electricity and seawater to make "photosynthesis" hehe

7:08 "you did this in like 6th grade science or something like that" well i would have if my teachers where actually interesting and didn't just teach me me songs like the water cycle song out school never did science experiments we always where just told that something would happen if we did something else no hands on projects ever really happened except the few that where like make a bridge out of spaghetti or whatever but those where kind of basic. idk i just kinda hated my old school we never learned much it was really boring and made learning the opposite of fun but i have learned alot from you and some other youtube channels i wish i had better teachers cause all the ones i had where really boring my family tried to find a better school but we never found one but thats fine ive learned alot on my own to make up for it

The C in the CO2 is a byproduct of the crew's metabolisms, right? So ultimately the job of a scrubber is to suck the excess food out of the air and shoot it out the side of the submarine.

A clinker is a term that goes back to the days of burning coal. It’s a lump of fused coal residue. Coal fired steam trains had to have their fire boxes cleared of clinkers.

Why don't they use an OBOGS like high altitude aircraft. It's uses zeolite and a pressure swing system. OBOGS stands for on board oxygen generator which you could say all of these are but OBOGS is understood to mean said method.

My only contribution: "Clinkers" are the generic name for the waste material that come from burning coal (among other things). They do indeed make "clink" sounds as you shovel them out of a forge or furnace. At 12:45 the by-products look a lot like the structure of those, and I'll bet engineers familiar with coal engines had something to do with these contraptions somewhere along the line

I have a buddy in the navy who told me that basically, the only reason subs come back to port at something is just for supplies. If not for supplies they would just stay out at sea forever. He told me food was one of the big reasons, they can almost make everything they would need, I'm sure there's some other things too but, why not just do what whales do? Put something on the sub to collect krill and other small organisms to make food with. Like intravenous food or something

A better solution would be to split the C from the 02, then all you would have to do is get rid of the carbon left over.

I have to say, I enjoyed this video immensely. I served on the USS Lafayette (SSBN 616-G) from '78-'83 and I just happened to be the CAMS tech on my boat. It's been nearly forty years, so obviously there have been many upgrades(the display screen being the most obvious). But, none the less, seeing the cabinet and hearing crewman Dow discuss it's operation...I found myself in a state of reminiscing. Good times... God Bless our Armed Forces...and most especially our Submarine Fleet.

@SmarterEveryDay Somebody probably posted this already but I can't find it, so here goes. I can say with quite a bit of certainty that the "preheating function" the Dow was talking about had something to do with a heat exchanger (there is a wikipedia article about heat exchangers). The lean MEA from the boiler-stripper is too hot to absorb any CO2, so it has to be cooled down. Conveniently, the rich MEA from the absorber tower needs to be heated up. So a heat exchanger will do both at the same time using the heat from the lean MEA. This means that less energy from the reactor is needed to facilitate this process. I hope this helps.
Rassul Li
Rassul Li 18 dager siden
In case it doesn't make sense, lets use an example. say the lean MEA from the boiler is at 100 C, it has reached it's saturation equilibrium (very little CO2). It now doesn't pull CO2 from the air unless it is cooled down. So it goes into the heat exchanger with a hypothetical 100% efficiency, and cools down to 20 C (the temperature of the rich Amine), in that process, the rich amine rises up to 100 C from the original 20 C. At 100 C, the rich MEA is not at equilibrium, and tries to get there by releasing CO2. Sadly, nothing in the world has 100% efficiency and is perfectly insulating, so additional heat is applied by the boiler-stripper.

Sounds scary that they are running on the secondary system for oxygen because their primary is broken ... Probably they have some rules about how soon they need to fix it. I guess they can always surface if things go really really bad.

I'm 25, studying electrical engineering, and I learned so much in this series! I've never been fascinated with submarines until these videos. What I found extra fascinating was this episode especially highlighted the parallels between surviving in space and under the sea. Now if only these vessels were rated for deeper elevations in an effort to use their advanced sonar technologies to rule out if these Pentagon-confirmed UFO videos recently in the news, which on one occasion has been seen traveling between air and water seemingly unfazed, originate from the depths of Earth's unexplored oceans or not. If you think about it we actually know more about the surface of the moon or Mars than we know about the surface of the sea floor on Earth!
