plans
Mike,
There are a lot of powerful concepts with HV electromagnetics, but what these guys are doing is far from what Gray did.
Also, over the years of them selling their plans, I have yet to see anyone get over 1.0 cop on anything they claim. Especially, their oil/drum heater.

so far i have been useing the existing rotors in a modified form while trying to find a place to buy the right kinds of materials to build new rotors with.... this has been quite vexing, i am looking for sheet material to make laminations from. i have googled various terms for motor/transformer laminations and it seems theres a much bigger variety metal than i thought. commonly called "electrical steel" but a whole slew grade terminalogy. a local metal fab shop in town with a laser cutter has sheets of astm a36 cold rolled steel which is not considered "electrical steel" and other companies i talked to on the net have told me they think a rotor made with that kind of metal would get really hot! i called a local metal supplier to talk to there metalurgist about it but he didnt know anything about the magnetic reactions of diferent grades of steel!!
so he wasnt very helpful. the best information i found so far came from, national material company
