You are confusing angular velocity, rotational energy, and kinetic
energy with angular momentum and linear momentum.

What you're on about is varying net system momentum - ie. an N3 violation,
linear or angular. Sure, if the motor's off then CoM / CoAM applies, and
momentum's constant. I'm no

With the engine turned off (no thrust) putting the tether in place

They are closely related, as angular momentum (in classical mechanics)
is the sum of the angular momentum of each object in the system measured
about its own axis, along with the sum of the linear momentum of each
object crossed with its radius vector. Total angular momentum depends

Are you supposing that there's a fundamentally different interaction
manifesting inertia in angular vs linear accelerations? "Angons" vs
"linons" or something?

Just to point something out -- the EM drive obviouslydoesn't need to be
outside the craft to work, since it doesn't ejectmass.
Furthermore (and consequently), it violates conservation ofmomentum,

That's interesting. That would resolve the conservation violations.

That might be tricky to test for. For ordinary particles, you would put the
thing in a box and see if it stops thrusting. But neutr

A curious facet of the EM drive, such as the one now operating on the
Chinese space station is that it need not be on the outside of the
spacecraft, it’s thrust is independent of
“smooth” means. Let the
definition of ‘smooth’ games begin!
