Correct me if I missed something, but the STATOR magnet is IRON, not alnico! Its the stator (iron) that is demagnetizing, not the alnico magnets. Which makes sense; the alnico magnets are going to have a much stronger B-field than the iron, and perhaps the alnico magnets are forcing the magnetic domains in the iron to lose their alignment... Why the different magnets? There was some mention of asymmetry involved... is it asymmetric with respect to magnet material?

Yes, indeed! I tracked down some additional info on the subject. A very good description of Mylow's detailed explorations of the HJ configuruation can be found at the Pure Energy Systems web site, by Sterling D. Allan: http://pesn.com/2009/03/20/9501532_Mylow-replicates-Johnson-magnet-motor/ http://tinyurl.com/cwjkzy Mylow's rotor assembly consists of a flat aluminum disk (diameter 17 1/8 inches in diameter) with rows of alnico magnets glued to the surface in various asymmetrical configurations. Excerpts, and of particular interest to me: > Mylow is aware of the eddy current phenomenon: If you drop a magnet > down a tube of aluminum or copper, it will drop much more slowly due > to the eddy currents being created as it passes by the aluminum or > copper.

In regards to the energy issue, whether OU might exist, the following paragraph, IMO, is particularly revealing: > He [Mylow] stopped by the place he goes to get the stator magnet > remagnetized yesterday afternoon to get permission to give out their > name and address as part of our reporting. > They preferred that he not do that since they are doing this as a > favor to him, and they only want to receive commercial orders.

A good way to prove or disprove my conjecture would be to replace the aluminum disk with non-ferrite material, such as a high-strength plastic like Derlin. Machine a sheet of Derlin to the exact same dimensions as Mylow's original aluminum disk. Glue the alnico magnets to the disk and see if it turns. My prediction is that the Derlin disk configuration will not rotate because, as Mylow suspects, the "eddy currents" within the aluminum disk are playing a key role in the "physics" involved. With non-ferrite material, no eddy-currents, no rotation. Please note that the rotation speed of Mylow's aluminum disk appears to be extremely slow to begin with. It was recorded to be turning at only 77 RPM, this after a couple of days of continued use according to Sterling Allan's notes. The report states, "...the magnet works best for about two to three hours, after which it begins growing weak." IMO, there is very little energy that can be extracted from such a configuration. The disk begins to slow down after continued use as the alnico magnets slowly demagnetize. It does seem likely to me that the electrical eddies within the rotating aluminum disk is the culprit for the demagnetization of the alnico magnets. Perhaps I missed it, but what seems to be glossed over in Sterling D. Allan's analysis is the fact that Mylow's alnico magnets have to be re-magnetized - and particularly at what cost. Here's the key point: I suspect the amount of measured energy expended each time to re-magnetize Mylow's alnico magnets far exceeds the amount of energy that could be "extracted" during the total time period the aluminum disk is rotating. Regardless of whether OU exists or not, this is a fascinating experiment, and I congratulate Mylow's efforts. In a sense Mylow goal was to get the damn contraption to rotate, and the bloody thing is doing just that!!!! I hope Mylow enjoys a long overdue vacation, and continued cherished anonymity! Final thought: Regarding my diatribe that, IMO, no OU actually exists within Mylow's device, nothing would please me more than to be proven wrong.
