Originally, the anti-gravity mechanism creates a gravity field upwards stronger than Earth's gravity. The jade disc wheels around the torus not shielded from this anti-gravity field. In the diagram, on the right side, gravity downwards charges the jade; there should be no bottom support.
Have a nice day...
