ION, Itsu, All,
I have to ascertain some basic facts that I have mentioned before, although not explicitly enough. This may have created some confusion. These basic facts were mentioned in my reply #76. What I am going to say now, which stems directly from these basic facts, has to be taken very seriously.
The magnetization frequency range for the device in Fig.7 given by McFreey, 50 - 4000 Hz, is very wide. This does not mean that every gain material will work at the lower frequency range. In fact, according to the information presented in reply #76, the device in Fig.7 will not work at all, at 50 or 60 Hz, if the gain material is copper or even aluminium. The lowest frequency for copper will be close to 1000 Hz, it will be slightly lower for aluminium. The device in Fig. 7 becomes quite difficult to implement at these frequencies. The device only looks simple when presented as in Fig.7. As I mentioned before, device in Fig.6 is much easier to replicate (Fig. 6 is the essence of Mark's technology). I can guide you through this as well. My offer of guidance was, in fact, related mostly to the device in Fig.6. Itsu's coils can be used in this implementation. Long coils are not needed.
I also have an idea how to simplify the approach in Fig. 7, but will not present it until I verify it. I hope this helps.
