I have just visited the library here at Southampton University to take a look at it. When the motor was energized, it accelerated the lead flywheel toward it's top rated speed. Harvey Morgan has confirmed that there is a kind of spin field momentum that Professor Eric Laithwaite had in mind when he performed his dual flywheel tests with a separating partition between the two wheels. Should anyone decide to research this further I would suggest that they take account of what my 'vacuum spin' theory is about.
Aether rotation involves radial electric charge displacement and vice versa.
So, spin a flywheel and as it builds up speed there will be charge displaced radially in aether coextensive with that wheel. If the flywheel is thin in relation to its diameter and it has the face of another metal flywheel closely adjacent, the charge displacement might be sensed across the small air gap between the flywheels. It could conceivably induce an opposite polarity charge displacement in the second flywheel, and though not itself rotating initially, this might cause the second flywheel to have, inside it, aether in spin in the opposite direction. Then that second flywheel could begin to pick up that spin and so go around in a direction opposite to that of the primary wheel. Turn the drive power off and the first wheel stops accelerating and begins to slow down, but if that charge displacement is determined by acceleration it will subside immediately.
