Hey roger i like your industrious will to get some work done on this. If you do try it please be careful, nano coatings, electricity, un tested designs etc can all add up to danger if extreme caution is not utilized. If i were you i would not embark on certain parts of the research without a lab partner present, at least to point out the obvious and double check stuff.
I think it is unimportant that Keche is already seen as a charlatan to many, as it seems you trust him
enough to try replicating his blueprints. Aside from his track record i am always alarmed to see things like, "The primary
energy is vastly different from anything conventional physics has worked with in the past." Without any further explanation offered. I mean plasma is not outside the realm of physics, nor is electro magnetism, so at least a hint of what is happening would
be nice.
I am curious if you have studied Bruce Depalma, homopolar generators, faraday disk, or the N machine. Depalma studied electrical engineering at havard and taught physics at MIT for 15 years. A few more credentials then Keche.
Or if you have heard of Paramahasa Tewari. He was a nuclear engineer who worked for the department of atomic energy in india for most of his career. While he has not published blueprints for his generator design, he has published his work regarding the electron, and what he calls space vortex theory (no not just like decartes) which explains where the "over unity" energy can come from without violating the law of conservation of energy. The beauty of his work is it is married with and agrees with the accepted body of physics. He just delves into the structure of the electron as a stable vortex created around a void etc.
Again i dont want to dissuade you from trying, since i am sure you will learn many things in trying to replicate any design. Just keep in mind how much research and testing it takes to deliver a design thats polished and working, even on a small proof of concept level. Goodluck and please be careful.
