Ok.
So to say, this edy current , cooper magnetic "free energy" bla bla bla stuff is not wort to build and experiment with it.
Actually I'm not searching for any solution to heat my house, I have a normal heating system and it is working perfect for me.
I was just stumbled in that kind of articles on the net, and some of them wrote about that "invention" like an alien stuff...
I'm familiar with Lenz's law etc. but im far away from free energy, perpetumobile and that stuff you know...
