An important improvement can be made in the previous design: the second set of rollers (between the green sector at a X speed) and the outer ring (in red, and grounded) can be located directly on the outer ring, like shown in the second drawing below.
What are the consequences ?
First in some circumstances we don't need the second set of rollers: if the rim of the green sector is a real circle (not only a cross), we have just to put the assembly inside the outer ring, and the green sector will just roll easily around the internal rim.
IMHO it was the way used in the ancient time for the flowerbowl, a reversed waterwheel, like suggested earlier here:

where the 'double speed' wheel assembly acts as a hamster in her cage.
