    This is the first SmarterEveryDay video I’ve ever watched, and the thought I kept having every minute or so was “this is so cool!” Really impressed with the access given on the submarine and with the visual explanations of processes. Shoot, I’m *super* impressed with this video! Thanks for this really cool learning experience :)

    Submarines are one of those sci-fi-seeming ideas that, if they didn't already exist in the real world, I wouldn't think it remotely plausible that they could have built one the size of a large building over a century ago.

    the MEA is turned into a carbonate salt would be my guess. they would probably preheat the carbonate salt to keep it liquid when they put it under pressure so they get a smooth crack of the carbonate back to freebase amine. many amines form carbonate salts that are mostly solid with often low melting points hence the need for preheating so they can be pumped and pressurized. when ethanolamine carbonate is heated to the right temp it will crack the salt allowing the carbon dioxide to leave. this could be over the boiling point of ethanolamine hence the need for the pressure. I would say the ethanolamine was there choice in the least toxic amine to use as some of the other options are not too friendly :) the great thing about using a base like an amine to capture CO2 is that it is a simple acid base reaction to remove the amine from the breathable air that is expelled so I would say the scrubbers are just acid tanks. many amines that are small like this one smell of ammonia in there freebase state but as a salt have a fishy smell,. this fishy smell would be the smell that the sailors would be talking of I think. im going to make me one of those oxygen candles now :) I have never heard of them before but can think of some great uses for them. as always thanx for a great channel and another great video.

    The nuclear reactor/reaction is used to generate heat with boils water which creates steam which turns electricity generating turbines. That’s how all nuclear reactors work. Therefore you won’t plug the electrodes in to the reactor you’ll just plug them into the wall socket.

    Regarding the preheater: usually there is a rich to lean a mean exchanger in that position. Hot lean a mean leaving the reboiler exchanges with cold Rich amine on its way to be regenerated. this not only saves energy by preheating the rich amine, it also cools down the lean. Hotter amine doesn't absorb the CO2 as well
