    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 geta 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 nottoo friendly :)the great thing about using a base like an amine to capture CO2 is that it is a simple acid base reaction toremove 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 going to make me one of those oxygen candles now :) I have never heard of them before but can think of somegreat uses for always thanx for a great channel and another great video.

    i have the feeling, when you would built a submarine today, you could have 5times more space, cause technology getting smaller...

    Did anyone else see "Why don't subs run out of air?" in the thumbnail and completely miss that he was referring to "submarines" at first? I can't be the only one who very much misread that.
