>>11265084They don't have a super heavy built. They're not yet building one right now either. And their pad has barely begun construction. They're starting with Starship itself because that has a lot more issues they need to investigate and work out.
As for how they get that much fuel there, I'd suspect they'd use a pipeline like most of the airports in the world instead of clogging the roads with tanker trucks.
As for the far future, in his last presentation(might've been in the Q&A) Musk has stated that he's interested in producing his own Methane on-site from water, air and solar energy just like on Mars. This would mean a lot of the climate impact of Starship/Superheavy launches would be offset. But as I said, that's far away and will be pretty expensive to set up.
