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

I infer no "undertone" whatsover,I just read the thread .
And as a result am quite aware of Farmhands opinions on this as well as the purpose of his experiment.
thx

No offence, safety first. 

This time I tripped the house safety switch as well as my portable one, If I didn't warn the other humans of the possibility I would be in trouble for interrupting their TV programming session. hehehe And it did it while not even driving the transformer, I had the active line disconnected.

I guess I need to look at a variac schematic to make an accurate drawing and analyse it, there was 1.7 volts potential between the house neutral and my ground stake it's enough to force over 30 Ma of current out of the neutral line into the ground by the looks of it, I think the house grounds are sus, they need checking by an electrician, I think my ground stake is much better.

OK, now it's obvious why the safety switches tripped. See drawing below. If the variac was not there it might not have tripped the safety switch. If there is any current mismatch over 30 mA between the active and neutral lines the safety switch trips to save lives. This disallows any electrical connection to the grid and so an isolation transformer would need to be used, so that takes me back to my original experiment using an isolation transformer and my ground stake, except this time the ground wire will have an electrical connection to the high current loop.

The drawing below will not work with safety switches for obvious reasons.

Cheers

P.S. With 100 Volts applied to the transformer about 30 Watts is consumed and the single loop red cable has 188 amperes flowing in it. The ground wire is not connected to the loop in the photo.

Hi Farmhand
thanks for the test results
I did not use the neutral on the output.....  only a step down transformer  220 v  to 24 v    and the 24 v   winding removed with 2 turns
the loop end connections I can touch  with a clampmeter reading of 190 amps   .  this one I discovered while I accidentally touched the ends of the loop
the  60 w lamp is dim  maybe due to the winding   must have used the 220 v winding as output.....
the toroid used by Igor Moroz i think is more suitable to insert in the loop
the cable in the loop heats up very fast to 85 degrees Celsius  with 220 v ac  input
Beside earth connection   we can use a flyback hv  to inject on the loop ends   and the toroid within the loop can pick up the induction for the load.....
I think the Neutral you used and the Induction in the loop are the ones to be used for loading and will not trip the upstream fuse
Another way to increase induction in the loop is wrap the earth wire or copper tube and reduce heat at the same time

I'm not finished yet, looking at the drawing it has a + and a - so I think I'll rectify the output of a transformer (so it's isolated from the grid) and feed the "device transformer" with lumpy DC, that will give me a setup more like the Barbosa and Leal drawing. Meaning there will be a positive and a negative at the input to the transformer with the loop on it, and I will be able to try a load between the grounded loop and the negative side of the transformer input, as it is shown in their schematic. I'll see what happens with that.

Cheers
