    Perpetual motion is everywhere in space. Using that motion for doing work will always change the motion, and it will eventually no longer be useful. This is what a perpetual motion machine tries to do but can not.

      AFAIK even space will cool down and stop eventually. So not perpetual motion very low friction motion? I know that expansion also plays a role.
