Friction slows this. Even the gravitational differential of the planet slows this. It is physically impossible to have a system without energy losses, and it is physically impossible to draw energy out of this system for useful work without reducing the total energy in the system. There is no perpetual motion and can never be.
Then it isn’t free.
It can’t be.
