	THAT will cost efficiency, LOTS of efficiency,
	unless slowing is done with gears, or VERY carefully
	designed rotor.  And getting gears to live at
	50,000 RPM is tricky.  I believe that where
	Gas turbines are used for Shaft output (RR, Power
	Plants, choppers (??) they run them slower.  a LOT
	slower.

	Normal engineering practice limits such 3600 RPM and
	down.  Stresses in materials go up as square of speed.

	3,000vac and up.

	It CAN.  But.  It also needs to be INSULATED for the

	are routinely wound for 5,000VAC and thereabouts.)
