      Wouldn't 'Let's go get smarter together' or 'today' or something of the likes be a bit more appropriate, due to it being an instance of becoming smarter rather than a culmination of instances at once? I feel like 'let's go get smarter every day' for one specific instance of becoming smarter is a bit misplaced and misnomed in comparison, and leads to a moment of awkwardness in my mind; as if it's advice, rather than a welcoming invitation. Maybe it's a solo perception, but here's to hoping this mention of insight can provide some benefit. Cheers, Destin.

    Flat coke still has CO2 in it, but it has the same amount of CO2 as the atmosphere whereas the fizzy coke has an excess amount of dissolved CO2 and it needs to escape and equalise. This is why coke doesn’t fizz before the bottle is open. And this is known as Henry’s law for anyone interested, it’s one of the gas laws.

    I think they call them clinkers in reference to a blacksmithing term (it was probably used in many other industries, too) It generally refers to un-burnable impurities that remain after whatever fuel you're burning has been spent. Like when you are blacksmithing and burning coke (purified coal), you get solid lumps of impurities that you need to remove.

    The reason why they are called clinkers is because of the sound that is made when they cool down, same thing happens when you burn coal, you also get glass/silicate and ash as the byproduct with coal. My knowledge of this comes from working with a coal boiler in our house that used to be a part of a train engine, I would ask my dad questions about it all the time. It was used to heat a huge church house by the way, it was pretty good.

    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!
