@Stan Ervin Simple answer. The Chinese actually tried this exact experiment on the dark side of the moon in recent years with complete failure. Other similar experiments are being done on the space station with some success, but sunlight is still necessary. Some micro organisms were tested with success, but that information is apparently not available to the public. The idea is reasonable until put into reality. All known oxygen producing plant life (including algae) sufficient for human breathing require some form of sunlight in their photosynthetic process for oxygen to be produced. Submarines have been in existence since the Civil war, if there was a way to utilize plants in some form or other I'm sure the scientific community would be celebrating it right now. The Mars missions depend on such a discovery. There are multiple test facilities around the world challenging people to survive in the most inhospitable environments in preparation for the Mars missions and oxygen generation is the number one priority, water is second, and food, survivability along with many other situations follow in priority after that. In this instance there is overwhelming evidence in the proof of concept phase to eliminate that particular possibility, at least for now. I agree that there is always new information developing and the idea is absolutely reasonable to continue research because perhaps someone will indeed discover the missing ingredient. I actually grow, propagate, graft, and merge different species of plants and trees. Trying to maintain these plants in their optimal environment is challenging enough, imagine the types of modification required to sustain them without those systems. I am sure some of those modifications are probably happening on the station. The purpose is to go beyond the information we already have and explore new possibilities. I think the plant and algae ideas have huge merit; however, there are significant setbacks because with reduced sunlight oxygen production is reduced and toxicity is increased. The unknown is where the real possibilities are just waiting to be discovered.

@SmarterEveryDay You may want to do some research into Raycon. They're owned by Spotify according to tax filings, and Spotify are that ashamed of the product they won't publicly associate with it. Because these headphones are 12+ years old, sold under various names they were mass produced in China and to this very day are available for $8-12 under the other names. Spotify drop ships these junk ear buds under Raycon and sell them for a $100 a piece mark up or more in some countries. They are not a good product. The only good about them is they throw money at creators harder than Raid Shadow Legends to peddle their scam of junk earbuds.

I cringed a bit when you said "filtered by reverse osmosis". We in the membrane community usually refers to filtration as anything mechanically separated, ultrafiltration is the cutoff for mechanical filtration, anything with smaller pores/molecular void spaces like nanofiltration and osmotic processes we call membrane separation. It can be a bit confusing since "nanofiltration" has the word filter in the name.

Ask someone what happens if there is a leak on a nuclear sub. I'd bet the farm they would have a more intelligent answer than "well then we would have a leak". Thanks don petit. Sorry but you mentioned the lunar lander and i remembered when you asked Don about a leak in a space situation.

Cold liquids tend to absorb (for lack of a better term) gasses more readily than warm liquids. This explains why cold amine is sprayed, compressed...etc.

To preface this I don't work on a submarine but I have ran amine units. Usually the exchanger to heat up the rich amine before the stripper is exchanging heat with the hot lean amine to cool it before meeting up with the gas, in this case the air. Lean amine usually works best when its somewhere around 15 degrees warmer than the gas it is coming into contact with.

Brilliant and detailed explanation of all the processes. I thought it was much more simple, and I had no idea they had to use oxygen candles and have a controlled metal fire onboard the sub, YIKES!!! Amazing solution but it seems so brute force when operating beside a nuclear reactor!

This is cool! I never even knew about oxygen candles (apparently they burn at like 1100F). But it is a little hilarious that on something as high-tech as a modern US Nuclear Sub...they use 9-in nails to help keep everyone alive. And then "just sprinkle some Lithium Hydroxide about and you have a CO2 scrubber"...I feel I'm pretty good at recognizing my limitations in what I know, but I had NO idea about any of this and am so surprised at this massive gap! So cool!

Clinker : is from Dutch, and was originally used in English to describe Clinker bricks .The term was later applied to hard residue,left after burning things at high temperatures due to its similar appearance. Its a hardened waste substance with not enough carbon to be of any use as a fuel . it was sometimes used for pavement. So their spent candles might make handy garden edging 😉 . thats my unsolicited 2cents 😶
