If you spin for acceleration, you've got to have beefy designs to keep the thing from flying apart.
I'd imagined just aircraft wire (though I know there is better stuff now) for the 'rim' and a mylar or multi-layer film tube for the habitable
area. Using some of Buckminster Fullers super strong but lightweight designs should do the job. A heavy hub, maybe a water storage facilitiy, should
provide some stability.
You also need a relatively big space station to get it to work. Otherwise the gradient across you will make you yack like a sick cow. Consider: if
your head were at the axis and your butt at "1G", it's going to feel pretty damned odd.
I remember 40 years ago or so, going on a fairground ride where they spin a group of people in a barrel, vertical axis, I think there was room for at
least a dozen, and then move the floor down so you are stuck to the wall. It was weird, but after a short while most people could stand up, heads all
towards the axis, and do some pretty simple movements. The ride attendents were the experts of course. So yes, weird with a small diameter, but I'd
think fairly easy to adjust to if it were a couple of hundred feet dia.
There's other issues, tumbling and precession problems with weight imbalances, for example.
Yes, many challenges, but for long missions, or voyages, I'd think it was still the way forward. Guess I'm disappointed, being a long time SF fan,
that no plans seem to be on the drawing board.
Good posts all around in this thread.
Agreed! And thanks for the info about Gemini, I was not aware of that experiment with rotation. Have to look to see what reports there were on that,
and any conclusions.
