There is an infinite supply of electricity in the universe. All you have to do is
rotate a piece of wire in a magnetic field FFS.

Rotating a piece of wire requires energy.

More than is produced by rotating the wire.

Then you rotate several bits of wire to give you the energy for that one.

No it's much easier than that you rotate the field. ;-)

Something to do with crop rotation IIRC ;-P
