[Spaceships 7] Homebrew: Expanding on Gasbags

I'm fairly sure that if hydrogen had twice the lifting power of helium (as suggested by your numbers) we'd use it for gasbags more, flammable or not.

however, spaceships does things by weight, and that's throwing me for a loop when I try to compare the numbers online with the numbers on the internet: people are always comparing volumes.

which means that you can probably save weight by using hydrogen, but you should probably be paying twice as much for the system because the expensive part (the gasbag) is twice is big, even if the whole things weighs about half as much.
