    As a Submariner, the real limiting factor in how long a Nuclear submarine can stay submerged isn't oxygen, it isn't food or supplies, or even fuel. It's crew sanity. 😅

    subs are so scary im afraid of anything bad happening like that one russian sub that where a bomb blew up inside and killed a lot of the crew, then the survivors went to the back where it was safe; for now. and then a second explosion happend which killed more peeps. the only people who are alive by this point are a group of peeps who are in the very back part then, due to the oxygen generator breaking in the blast, they start running out of oxygen and it begins getting harder to breath them, being smart they tried to jumpstart the gen using some (some type of science tablet) but one of the peeps drops a couple into the salt water, making a third blast killing almost everyone. with the rest (injured surivures) they sufficate on carbon dioxide.

    submarines 60 years ago didn't had this much technology dedicated to produce air alone oxygen, they were still using filtration systems from the late 40's if they had any, for oxygen I don't know what were they using.

He worked on an aircraft carrier for the US Navy in some job related to nuclear power (which he never gave any details on).

    So, here is a challenge for you and probably for your other smart friend, the one who made the explosive baseball bat. What would happen if you get one of those huge fireworks that we see on the 4th of July and send it to the border of the atmosphere on one of those weather balloons and make it explode there. The real challenge is: how would you figure out how to film the explosion at enough distance to be able to appreciate the explosion and what would happen. Is there going to be enough oxygen for the thing to explode?

    Heat of absorption of CO2 and partial pressure of CO2 with aqueous solutions of MEA has been measured in a reaction calorimeter CPA122 at 40, 80, and 120 oC for 30 wt% MEA solution and at 120 oC for 10 and 70 wt % MEA solutions. Heat of absorption measured in this work is also differential in loading, i.e. CO2 has been added to the reactor in steps. An experimental set-up used by Kim and Svendsen (2007) has been used in this work after a small modification. Experiments show that heat of absorption depends both on loading and temperature, though the temperature dependency is not as high as was reported earlier.

    A subtle meta-analogy there between the oxygen candles and the reactor on the ship. The candles work by producing more oxygen than they consume, and the reactor works by producing more neutrons than it consumes.

    12:44 they are called "Clinkers" because in many industries the waste created if it is semi-solid and porous, it's called 'clinker'. e.g. the cement industry. For example, the ash formed by burning coal in a boiler will deposit 'clinker' ash or a glassy slag on the walls or surfaces of the boiler. Some bricks are also called 'clinker' bricks because of the porous appearance of them.

    Given that the problem is too much CO_2, and not enough O_2, I’m surprised the solution doesn’t involve a chemical process that strips the carbon off of the CO_2, completing both the oxygen generation and carbon dioxide scrubbing at the same time.
