The magnets in an alternator, again, are producing electric current. They're not producing the physical motion.

And an alternator still requires energy to make energy. It requires electrical energy to produce a field for the stator, and requires physical energy for the armature to spin inside that field, creating electron flow.

See: Physics - Conservation of Energy
And: Physics - Laws of Thermodynamics.

I, too, would love to see a magnet motor that actually works for something other than a dreidle (spinning top). I still don't think that those working on them are any closer to finding maturity in the field, though.
