  • 19:29 I was very interested in how he decides if there is a problem with the 02 not rising quickly enough, do they have a chart they refer too or is it intuitive? Would have liked to have heard more about that but it was an interesting video none-the-less.

  • That's a good question. There are predetermined ways to signal the "safe word" without actually being able to say it. So, the dom would know what to look for and once the sub gives the signal, the dom stops choking them. Hope this helps!

  • Even more did Apollo astronauts have enough oxygen for their long trip and, even more so, breath oxygen for so long on the latter missions with Eva's of 8 hours? Rebreather equipment?

    • P.S. I believe they did it...just curious how it was done.

  • Awesome this is some thing I wondered about for a while now.

  • How is sewage handle on the submarine? When I worked on an offshore production platform the process was electrolysis that turned the sewage into calcium and then dumped it into the ocean.

  • It has to seem obvious to most people. But I have to ask why would they not use plants? Or do they and how limited are plants at helping the oxygen situation? My guess is not very helpful and the requirements would be fast compared to the size of the submarine and the amount of work they would need to do but I'm curious about what it would take for the submarine to be able to use plants instead

  • Mir Incident: On February 24, 1997, six crew members on Space Station Mir faced significant danger when fire ignited in the solid fuel oxygen generator. The searing flame, which erupted from a fuel cartridge, cut off access to one of two Soyuz escape capsules. The module’s narrow space made it difficult to fight the fire, but with teamwork and composure, the crew prevailed. Although the incident would raise tensions between the teams on the ground and on orbit, both sides would learn valuable lessons applicable to the design of the joint U.S.-Russian International Space Station.

  • Cool! So the only consumables we need to breathe outside of Earth's atmosphere, besides equipment, are water and electricity/energy. Water can give us oxygen and hydrogen (which can be used as fuel to generate more power), MEA equipment can continuously remove carbon dioxide as long as it's powered. And there are unpowered chemical backups that can be held in storage for emergencies or if machines break down and need repairs. Add nutrients for plant life that can be recycled from waste, and you'll also have the basic materials needed to farm crops and live indefinitely if you have the right equipment and can maintain it. With these clever technologies, with common basic elements consumed by the right machines humanity could settle outer space! Water is abundant and so are sources of energy: nuclear, solar, and often heat and wind. Submarines are pioneering artificial atmosphere technology!

  • 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.
