Energy from the Ground - Self powered generator by Barbosa and Leal

[John.K1]

I am also a little bit confused with using the AC. The condition was to have POLARISED LOOP (+) .  It is quite logical as the grounding potential is (-)  and with the help of magnetic field can be free electrons attracted or pushed in to the loop. But this is not case of AC  (i think)  Also , I could imagine better functionality with very sharp ON/OF  - not sinus?

I think they used the ground / loop induction and transformer secondary one  open line to limit the increase of current in the loop
the electron trap is in the loop cable   
using 3 transformers with 2 turns each   the third to the  220 v ac / 12 v dc converter  back to the 12 v dc battery that supplies the 2 parallel primary of transformer 1 and 2
the loop in the third transformer is extended and closed by a 4th coil  primary  400 / 220 v ac   and secondary open line to one leg of load     
earth to another leg of load
Now you have a self generating power supply    hope somebody will try this

   John.K1:
   I'm not sure about any of this, either.  Maybe Toto can try it and let us know if he ever obtains any positive results. 

"The condition was to have POLARISED LOOP (+)" .
  Can you explain what is meant by having a "POLARIZED LOOP", in this case.

[John.K1]

I guess POLARIZED LOOP simply means to connect it to the positive terminal? As on the picture I posted before? That's what I read in their patent application? Have to experiment with that. And to be honest with you I do not believe it is so simple as they state. If yes - is here anybody who proved OU on that simple device? Sorry my pessimism I have no transformers to mess with that at the moment. I am just winding the E core and will try to use pulsed DC , 3 loops of pickup wire and grounding wire winded on that.
