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

Chet:

If Clarence is real he will do just what you are hoping for.  But, if he presents amateurish junk data then that should be stated by someone.  Don't blame me for "scaring him away" either.  I believe he claims he is a 77-year-old grown man, correct?

BringDown:

I can only assume that you are stating that from a position of ignorance.  Your computer, your cellphone, and your multi-megabit home wireless network, and your 19-megabit per second over-the-air local digital television stations are all working just fine, correct?

MileHigh,

Sorry mate but the computer, cellphone and the wireless networks are worthless heaters and you know it. Don't know if you know how they work or if you are claiming that it is the only way to work with electric circuits but you should take another good look at the claims in the books.

Forget Barbosa and Leal for a moment because that would be too much for you to handle. Who can tell me the theory and what is going on with this simple circuit ? Anyone ?

First, that is no where near "10 times more light' as claimed.  Second...what is so special about what he is doing?  He is using a variable air cap and is changing the capacitance of his circuit.  His inductor was changed by the addition of the magnets to the ferrite. (We all did this 7 years ago in the JT topic)  Then he added a ceramic cap to the inductor.  Where is the short?

Let me know when he can light 400 leds from his single AA battery like I did 7 years ago, and then we can talk.  Every one of my 400 leds were brighter than his "10 times brighter" leds

But there is something wrong with it. The big 4 awg secondary became way to hot!!! the plastic around the conector melt after 2 min. ...

Hi Wistiti. From Clarence's description of having very low current (around approx. 1.3 to 1.5 Amps or so) in his secondary loop
(with no load connected, I think), it sounds like he may well have the two secondary windings connected to each
other as phase opposing. Try connecting the connecting wires on the secondaries the other way around, and see
if that reduces the current in the secondaries.
All the best...

Well, it's hard to state exactly why when just looking at that clip because there are no scope traces to be found.

The guy says this: 

This joule thief works much better when the ferrite core is shorted with a wire - a magnet or a capacitor. I adjust the trim capacitor for the best resonance.

He says "better" meaning "brighter."  Notice that he doesn't even discuss the fact that the draw from the battery has increased.  He says "best resonance" but the problem is that a Joule Thief doesn't even resonate.

A possible short answer is that the effective inductance of the toroidal transformer is reduced a lot, causing higher frequency operation and increased current draw from the battery.   But without a proper bench analysis you are flying blind.  However, without some kind of agreed upon metric like Lumens per watt of power draw, "better" is not even defined.
