I'm guessing there would be some environmental impact? It can't exactly be carbon neutral burning all that fuel?

It can be if the fuel is synthesized from carbon dioxide in the atmosphere with solar as a power source.

Doesn't have to be carbon neutral; just has to be better, or not much worse, than whatever alternative transportation you'd use to get to your destination.
