You are correct!  I should have said a sphere with 1 meter radius, not
diameter.  I found the energy needed to raise to voltage from 0 to 1 Mv
with respect to ground.  2Mv reqires four times the energy.  If the sphere
does not arc, soon the motor will not be able to force charge into it at a
given rate.  The power is probably the intergral of this function over

Glad someone is checking up on me :-))
