    Even reusable rockets use a tremendous amount of fuel. Falcon 9 burns 700,000 gallons per second.

      Untrue, that’s many times over the 25,000 gallons of kerosene they keep on board. That’s still a lot of gas, but not 700,000 gallons, not by a long shot. If it burned that much per second it wouldn’t even produce enough thrust to carry its own fuel payload

        To inject a source, there’s 395,700 kg total propellant on the first stage, and a burn time of 162 seconds. That gives about 2,442.6 kg/second, and assuming it’s fuel balanced it comes out to something like 700 liters of RP-1 per second. Could OP have been using thousands of gallons instead, by accident?

        It’s still a lot, though, while a space elevator is just a really tall elevator, or alternatively an EV that goes up and down.
