All you would need to get the rotation right would be a sidereal
drive from a telescope equatorial mount.
If you extracted any energy from the wheel motion wrt earth though,
its angular velocity would change to closer to that of earth, until
it matched and no more ennergy would be available. No free lunch
there, but the answer to the above question is yes.
