I might try that, but it would be a different concept. And there is already an entire book centered on this idea :-) * GURPS Traveller has better modular vehicle rules than 3E Vehicles or the Expansions. But neither of these is very good when it comes to big multi-module stations -- how do you deal with the stress when one module has the engines and the others hang from each other? * Modules for a ground station would have a definite up and down, and some sort of landing gear (real skids or underbelly skids, probably). A space station has more freedom. > >One kW-hour from a TL9+ fuel cell requires 0.115 H and 0.0575 > >LOX, roughly 0.62 lbs. plus tanks.

One rE cell is 100 kWh, so that powers a one-ton hyperdrive for ten hours, not one, right? So 4 pc, not 0.4 pc.

I can't guess the pricetag, but probably over $10M.
