Yes, of course. I think you got almost there - to finding a glimmer of
the ultimate tactic to push this to the limit.
Well, since were pushin' the limits . . .
Another well respected engineer friend of mine used this calculator:
http://www.magnetsales.com/Design/Tools1.htm
and came to the conclusion that, with the right configuration of rotor
magnets and spiral spacing he could get the bloody thing to self run
with, I think, seven rotor magnets. The combined torque from the
circular gradient on the other six overcame the "sticky spot" for
number seven. He even bought a number of 1" N48 cubes to give it a
shot. I'll have to encourage him to proceed with his toy.
BTW the flywheel discussion is quite interesting since the Steorn
forum seems to believe that the Steorn device needs gravity to get
past the "SS", ie, it only works with a vertical disk. Craigy seems
to be close to a replication:

For those not following the action, Grimer got Sean McCarthy to admit
that they had not built the 550 bhp motor. AAMOF, Sean says they have
never hooked one of their motors to a generator to try to make juice.
A bit suspicious, I'd say.
