From Steve's interview and close examination of the test rig image, I
believe I know how the Steorn machine works.
Note the large aluminum disk has what appears to be four threaded holes around it's perimeter. Also note that to the left of the disk are threaded holes in the supporting mechanism. I believe four NeFeBo magnets are attached to the disk in 90 degree increments and one Neo is attached to the supporting mechanism. A mumetal shield is arranged with a camming device such that when the disk is rotated by hand, the attractive force of the magnets adds momentum to the disk. When the rotor magnet is nearest the stator magnet, the cam drops the shield between the magnets sending the disk over the "sticky point". The cam then lifts the shield and the next magnet approaches. They had to convince themselves that they could generate energy so a worm gear is added to the drive shaft. This drives a large pulley which is belted to a small pulley. The mechanical energy drives a generator which subsequently drives a motor. In a similar gear/pully arrangement they drive another shaft. If you look in the foreground of that shaft you will see a mechanical brake which can add a load to the driven shaft using the brass screw. Speed sensors are on the ends of each shaft. Just my opinion, I could be wrong. Terry
