And there lies the rub. According to Mylow the Alnico magnets gradually weaken in strength, particularly after only several hours of operational use. What phenomenon could be causing the gradual degradation of their strength? Terry is right to point out that the fact that the Lorentz force (which I had eluded to) would seem to hinder the disk's rotational speed, making it stop dead in its tracks. I brought up Lorentz Force simply because I was at a lost to come up with a better speculative explanation as to what kind of "physics" might be involved. Again, I repeat, what seems to be glossed over here is how much energy must be expended to remagnetize the alnico magnets. My suspicion is that if one took that operational cost into consideration there may actually be no OU, since in order to "close the loop" one would have to use the energy derived from the rotating disk to remagnetize the magnets. From what I gather the rotational speed of the Mylow disk is woefully inadequate to the task. Therefore, no real OU exists here. > 2) Mylow reports the stator magnet getting cold during operation. > This has been reported before.

But that would involve a conspiracy of sorts! ;-) Also, such a hypothesis would not seem to need a stator PM configuration at all. I would think the rotor configuration would rotate all on its own. Incidentally, I recall Mylow stating that he reversed the position of the stator magnet 180 degrees. This, in turn, caused the disk to rotate in the opposite direction. Personally, I wish someone would construct a disk made of a non-magnetic/ferrite material like Derlin to see if it would continue rotating. My uneducated bet is that once the alnico magnets are repositioned on a Derlin constructed disk, along with the stator PM, the entire assembly will not rotate. My suspicion is that the aluminum disk is an essential component of the physics involved. But again, this is all speculation on my part.
