By TL10, fusion reactors are MUCH lighter and cheaper. > I'd assume that TLS would need filters and restocks of base algae > anyway...

My assumption means one meal out of 1,000 would be based on new stuff. That could be one meal out of ten for one percent of the population instead. > Is it intended just to get the crew there?

For realistic science, mass will be critical. This volume thingy comes from ancient Traveller game mechanics, which didn't want to re-calculate performance based on load. > Following the advice of TNG, you could have a ramscoop to collect > interstellar hydrogen and help pay for the trip (and preventing near-c > collisions with atomic particles)... VXi has a 'superscience' ramscoop and a regular ramscoop. I don't want to use the super technology, and the regular ramscoop is too heavy to make sense.

GT Spaceships had them. _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
