True, but I have no idea how to model that. Sadly the "Gasbag" description in
Spaceships 7 seems rather generic. I understand your concern about the expanded volume (I'd add 3 to the SM of the gasbag based on
my first quote from GURPS Mars) but I think the increased area of the envelope would be amply countered by Mars lower gravity and Hydrogen's increased efficiency as a lifting gas there. The cost issue I'll grant (what sort of premium should I tack on?) but impracticality is a tech issue I'm not qualified to comment on. I stand by my preference for Hydrogen as a lifting gas on Mars for reasons
I've previously stated and consider it an intrinsic part of my "Domed Mars" setting.
