      @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.

      @Gw Builder Rather sure that algae is an adequate producer of oxygen. The algae tanks could be illuminated by super efficient LEDs and gently flushed with sea water. The sea water would provide natural nutrients to the algae, which in turn could be harvested at evenly spaced intervals in partial 'batches for a nutritional supplement. Just an idea. Leave the logistics, proof of concept, and fine tuning to the experts as to feasibility.

    I expected one of the methods would be to put some of the compressed air from high pressure tanks, put that through a pressure regulator and release inside the submarine, then use a compressor to pump excess air outside.

    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 😶

    Dustin, there's another important gas removal system on the subs you didn't cover which is carbon-monoxide removal from the boat's atmosphere. Also, we always described the amine smell as a very strong fish smell.

    The preheater to the boiler stripper is nothing more than heat integration. Some waste heat from somewhere else on the ship is, I'm presuming, captured via a fluid and transferred there as a means to reduce the heating requirements of the boiler. Similar techniques are used in plants to offset utility costs. Here, probably done for safety reasons.

    I've seen an attempt to use this same technology to harvest hydrogen from water then inject it into the induction system of petrol/diesel engines which supposedly resulted in lower emissions and an increase in fuel economy however it's unclear if the end result was worth investing in as the gains were relatively small and therefore required that one do a lot of mileage for it to pay for itself. I believe the company was called 'CGON systems' and they were based in SW of England.
