All electrical devices depend on the motion of electrons. These motions are fully described by Newton's and Maxwell's formulations. No over-unity is possible. Cold fusion, on the other hand, depends on the motion of free nucleons. Now we are dealing with the motion of the strong nuclear field. Its a new ball game, not well described by anyone, and free energy may be possible.
What I did was apply Maxwells equations to moving carriers of the strong nuclear force and showed, at least in my mind, free energy was possible. What happens is a strong long range nuclear magnetic force is induced. My work on that area is now complete. http://www.angelfire.com/scifi2/zpt/chapterf.html I am now doing what I consider to be my last experiment. I have a small copper tube, the kind that connect refrigerators to the water system and I am using it as a wave guide. In the tube I have placed a wire coated with Vaseline. In the Vaseline I have embedded micrometer meter sized nickel particles. The device is now soaking in hydrogen. After a week or so I will stimulate the device with sparks. I have a neon bulb connected to the end of the pipe to monitor the RF energy in the system. I will monitor the bulb and temperature of the device. I don't expect it to work because I have already built devices of similar design that did not work. That's were I am at, papers complete and last experiment in progress. Don't expect to hear much from me in the future. Frank Zndiarsic
