More food for thought:
Imagine a wheel with an alternator attached on it's center axis.
Surrounding the wheel is a set of permanent magnets, equally spaced around the wheel, all having their south poles pointing inwards towards the wheel.
At the rim of the wheel there's an equal amount of electromagnets, which are all powered by the alternator through a set of solid state switches, which are fired according to a specific scheme.

As the wheel turns and the electromagnets are about 10 degrees ahead of the permanentmagnets all the electromagnets are energized to make south poles on top, which creates a repelling force between the 2.

When the electromagnets are 1/2 way between the permanent magnets the polarity of the electromagnets are switched, making north poles on top, which creates an attractive force between the 2.

As the electromagnets closes in on the perm.magnets they're all de-energized at about 10 degrees before they meet.

Then they stay de-energized until they're about 10 degrees ahead of eachother again and the cycle is repeated over and over.
Question:
Would the wheel want to turn itself around according to the alternating attracting/repelling (electro)magnetic forces, making it accellerate......beyond control....?
Feel free to enlighten me as to why this never would work IRL.
