Spindizzy

The Dillon-Wagoner Graviton Polarity Generator, or more informally Spindizzy, is a kind of Gravity drive. As per the source material the Spindizzy affects gravity through rotation and magnetism. The original fictional concept was that if rotation + mass produces magnetism via gravity then rotation + magnetism produces artificial gravity. This was based of off the then not very well understood, and somewhat inaccurate real world measurements of the magnetic fields of large rotating masses such as the Sun and the Earth.

While the fictional Spindizzy drives were more efficient if they were lifting larger masses, there is only one known example of a Fenspace Spindizzy, Grover's Corners, so there has been no basis for comparison.
