I wonder how feasible it would be to rotate a ringworld at a speed not to replicate gravity, but to negate the sun's gravity. So at 1AU it would orbit in roughly the same length of time as Earth itself.
- TheLoneWolfling 12y agoYou'd actually want to rotate it at slightly faster than orbital velocity, I think. Tension is much stronger than compression, especially at larger scales. But then you don't have the "nice" way of keeping the atmosphere in.
- electromagnetic 12y agoMy thought was something like a Stanford Torus, because then you could simply add additional rings on different orbital inclinations to build an almost sphere out of rings (reminiscent of M.C. Eschers drawing) and given good design you could create rings with day night cycles.
