      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.

    Why is lithium hydroxide not use in the exhausts of vehicles if it absorbes co2?

    • Faceless


      Ora fa

      Lithium Hydroxide filters are consumable unfortunately. They absorb the CO2 by reacting with it to produce lithium carbonate. Now it's obviously a bit more complex than that because why not just make them replaceable and keep it stored as lithium carbonate, for example... that's beyond anything I know but I would be interested in hearing it

    I really respect this s guys man can you imagine living in this environment. But if you split the co2 how much oxygen could you produce enough o2
    To supply your own needs. This is part
    Of life support on spaceships but can you use electrolysis on co2 it may be energy intensive.

    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.
