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

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

Hello Bill.
I did not ask for a passing judgement on the circuit thanks very much. I asked the gurus what the conventional electrical/electronics has to say about the observed effect ( ... even if it is feeble).

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.

It's very hard to respond to that.  I don't think you think that your computer or cellphone are useless heaters.

What is your level of exposure to "the claims in the books?"

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: 
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.

MileHigh,
Draw the circuit and you will know the answer to what is causing the increase in output and along the way you'll begin to appreciate the B&L circuit.

What's that noise in the computer ? Look ma its a fan!

Take another good look inside your computer and let me know if you think its the best electrical circuit because it ain't. If you cannot understand why the fan is needed and how it relates to EM theory then I think you are not worth teaching anyways.

I know from experience that I am probably wasting my time stating this, but the topic of discussion here in this thread is about B&L devices...
There once was a time long before the advent of the internet that common courtesy was, well, somewhat common.
Not so much any more it seems...
All the best...
