    pretty sure it’s propelled by compressed air.

    still very wasteful, but at least not burning dangerous chemicals for funsies.

      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 (N2O)? Straight up N2 shouldn’t be changing to CO2 unless some very interesting chemistry is happening, haha.

            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.

          I think what they mean 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 gases aren’t created but rather just a state change. Cryo coolers also take energy to run.

      Yeah just compressed nitrogen, but still very wasteful and excessive and stupid. That’s enough. No one said it was putting out toxins.

      Dude, shut up. elon has data centers with diesel generator covered roofs, etc, etc.

      Your “uhh technically…” doesn’t help anyone here?
