I heard it’s nitrogen, which I think releases co² during the production process. You’re right though, could be worse; they could’ve used hypergolic thrusters.

Do you mean nitrous (N~2~O)? Straight up N~2~ shouldn’t be changing to CO~2~ unless some very interesting chemistry is happening, haha.

  They said during the production process, not on release.

    I’m pretty sure the “production” process is just compressing atmospheric air and separating out the other gases. The atmosphere is 78% nitrogen.

    It takes a lot of energy to compress a gas, and more energy to cool it so you can separate the nitrogen. Energy production typically (not always) releases co2.

    Ooh I misread that as being on activation, good catch

  I think what the means is that when making liquid CO2 you use a cryo-cooler. That cooler condenses the gas out of the air. Air contains CO2 and nitrogen (plus some other stuff). The games aren’t created but rather just a state change. Cryo coolers also take energy to run.
