I'd like to approach this from a different angle.
It obviously takes a long time to get Newman's flywheel to rev up to
around 100 RPM. It's also true that even with a tiny torque force
applied, given enough time (and minimal friction to contend with) any
heavy flywheel can eventually be made to

But I'll try. Be warned that I'll probably get this wrong.
First of all, saying it's a 1000 pound flywheel doesn't tell us much.
The moment of inertia of the flywheel is what matters, and that
depends on the shape, not just the mass.

Stephen,
If your initial and impressive stab at calculating the amount of
torque generated in the Newman flywheel appears to be tremendous, (and
I gather you seriously dispute your conclusions), I would agree with
you. And, of course, Newman ain't telling us how much torque is being
generated. He

If power equals energy over time I am not sure there
