    I supose there are some other details, because air contains just 21% of oxigen. We breath air (a mix of gasses) not only O2. Pure O2 is toxic for humans. Sure there may be some procedure to get pure air with the correct mix. It's much more than oxigen. I imagine a submarine as a big SCUBA diving aire tank. Anyway, great video like all others! Thanks for sharing.

    ocean has air. they take that air and filter out their co2. k done. dont really need a 29 minute video for that. also if im wrong then meh. but still my point makes more sense and is most likely infinitely safer than using nuclear power for oxygen. so one thing i never understood. why are we using nuclear power for a submarine when we can just use hydroelectric power instead. i mean your moving forward thus propelling water which means you have infinite clean safe energy and its stupid easy to filter air out of water for use. are we addicted to making things that are highly explosive as a power source or was there an actual reason for using a nuke as a battery in a confined metal tube. i can understand if its for things like storing nukes since most of the time you will be still and not moving thus needing that power but aside from that if your moving exploring etc cant you just use basic hydroelectric power instead.

    In 1979, a former nuclear submarine commander visited a hot site about 5 miles from me. Not too long after that, another former nuclear submarine commander gave a talk in my neighborhood. Three Mile Island. But they didn't come to talk about subs. I wondered about subs and how they worked but figured if I searched the details, I'd have all the Alphabet Agencies on my butt. In my travels I have met people of all trades, including clandestine ones but never met a submariner. Thanks for this excellent presentation. It has helped satisfy some of my curiosity about subs.

These young people are absolute experts in their fields and I am extremely proud of them! Most folks have no idea how important each job in the military is for the overall function of the military. May God continue to bless all the men and women in our military and America! Thank you all for your service and thank you, again for making this video.

    Hey Destin I just wanted to thank you for your videos. I love to watch and seldom miss an episode. Your passion and excitement for learning is so refreshing. We are so fortunate to have information and ways to learn practically anything, at our finger tips via the internet. I really don't think the younger generation fully understands what a privilege this is. Being that I'm on the back side of 40 I am amazed at how easy it is to find information and learn these days. Anyway I just wanted to thank you for your videos and dedication to education. Keep the awesome videos coming.
