guys, i'm new here. please forgive if i'm a bit clumsy or act like a fool. i was wondering how do you connect two rotating cicrcles. specifically, suppose there are two huge spherical disc( torus). there is a distance of, say, 500 m between them. both are rotating at thier indiviual revolutions. my question is: how do you connect them i don't want them to stop rotating ( minimising friction, of course). i have no idea what method or technolgy would be use for this process. specifically, i request you to consider this scenario in the light of space settlemnt( stanford torus). kindly help me.
