Random Musings

StevanC: Kudos! Excellent suggestions on the use of capacitors to make measurements. Incidentally, capacitors can also be called condensers.

There are SO many variables with this seductively simple-looking device. EXACTLY how are the coils wound? EXACTLY how are they wired? EXACTLY how are the cores constructed? What is the optimum rotational speed for any given build? What are the optimal dimensions of EVERYTHING? EXACTLY how does the non-magnetic shaft play a role in successful function?

Posted are a couple screenshots from the DVD. In watching the video I wondered about the non-magnetic shaft. In the chalk-board diagram John shows the magnetic circuit taking in environmental energy in four places: the midpoint of the stacked magnets, and the top and bottom of the shaft. It made me wonder if the core had to have a COMPLETE magnetic break at the shaft location. The chalk drawing shows the core being a solid piece with a non-magnetic shaft going through it, but is the relationship (ratio) between the core diameter and the shaft diameter important? It's not very clear in the closeup screenshot of the rotor shaft and core/coil assembly, but a set-collar can be made of non-magnetic material. Perhaps the each core (top and bottom) is actually two separate cores, making four cores in total?

This is just one more detail that may or may not be important, but certainly adds to the possible places where secrets can remain obscured, and/or overlooked. Wouldn't it be frustrating to find out that we were looking for the problem (or solution) entirely in the wrong place.

(Sigh...) As has already been lamented, wouldn't it be nice to have a working one to copy and then play with?
