This is only the briefest snippet of information, but perhaps this might give us a clue as to one thing that might be causing problems for Andrea Rossi and his team with the E-Cat plant — or maybe the E-Cat X (or both)
A reader on the Journal of Nuclear Physics named Rick asked Rossi: “Did you have to deal with the problem of the Eddy currents?”
Rossi responded simply: “Yes, it is an issue.”
Here’s a definition of Eddy Currents from Wikipedia:
Eddy currents (also called Foucault currents) are loops of electric current induced within conductors by a changing magnetic field in the conductor, due to Faraday’s law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field.
There is no detail in this brief Q&A, and I am very much a novice when it comes to understanding electronic issue, but I do wonder if there are electromagnetic pulses involved in the stimulation of the E-Cat, perhaps one consequence is the production of Eddy currents that provide some kind of unwanted interference that causes problems with the E-Cats.
