Default Re: GURPS Spaceships Design Spreadsheet

More wish list stuff:
  1. Campaign options to define non-standard operating environments. Examples:
    1. Local gravity. Could affect liftoff and ground movement.
    2. Solar irradiance. Affects solar power systems.
    3. Atmosphere molecular weight* and temperature (°K). Affects gasbag lift. (See below.)
  2. A "hot air gasbag" system that uses 1PP to heat the gas inside and thus increase the lift. Option: List of lifting gasses used to inflate gasbag. Each has its own lift potential. Default to Earth air.
I'm considering a Martian Blimp design and discovered that the higher Mol. Wt. of the Martian atmosphere would increase gasbag lift by 53%. (Assuming H₂ is used; CH₄ would have about the same lift on Mars that H₂ does on Earth).
