So am I, or to change them so they only get to use those as power plants to charge the
jump drive. No useful reduction in fuel consumption. That said, I'm willing to entertain
an improvement in fuel consumption at TL17+, as Megatraveller had. Jump range
might be capped at J6, but more efficient bubble formation and maintainence could be
a thing (not that my games see TL17 tech).
