Via BB, fun with physics:
I think it’s particularly clever that they made the track a Möbius strip, in order to demonstrate how the gravitational field can be used to both float and suspend the superconducting magnet. Reminds me of this bit from chapter 5 of Communion of Dreams:
The man was a bit of a lunatic. But he was a brilliant engineer who had an almost intuitive understanding of the Apparent Gravity phenomenon, and was the first to propose that it could be adapted for use as a propulsion system. He figured out a way to trick an AG field into thinking that it was in a stable inertial reference by projecting it in front of a ship, and thereby essentially have the ship – and generator – continuously ‘fall’ into the field. The Hawking was the first ship equipped with the new reactionless drive system.
