A couple of friends and I were having a drink last night and trying to figure out how you could engineer an omega so you could get from the central rotating section to either end without getting squashed in gears, or chopped in half as a doorway slid past. We had trouble seeing how it could be done. (admittedly we are an embalmer, computer tech, and a barman. Not an engineer, or starship designer to be seen.) Any ideas, or should I put this on the slighty drunk conversations shelf, next to my mates idea about how to sell the air that Jesus breathed.
