Good time, lancaIV!
This patent really belongs to Yanchuk, I gave it as an example of the interaction of the windings on the core! The generator of Slobodian, like his "desktop rotator," I have been studying from the very day of its publication. Last Generator with a motor, I'm not interested. The first two models are Slobodian, interested. However, according to my calculations, the model of 10 kW will not produce more than 5 kW. It has self-rotation, and it is true. But his model is nothing more than the symbiosis of Adams, Muller and Bedini. What could be a patent? A design can only issue a certificate.
I realized this when my model was developed by the UNI generator (second design, my closed Source project). This method is the same for everyone, we just several times invented what was previously invented and hidden. If you want to safely hide, put in a prominent place and slightly change the information.

In the first book, the price is reduced

Why to sell a book $55 if you know the secret of free energy?! 
How can you affirm that you know the secret when you have not been able to build a workable generator?
We have to be damn naive to buy that.

Are you probably joking about the secret? For such a sum, just hand out. Good lunch is more expensive. And more importantly, the "Big Secret" is still on the way: "there is little time for translation"!

I wouldn't even accept the sum if I was paid to read such huckster's spiel.
