Single AA battery to light WHITE LED for long-long time

[Groundloop]

@Bill,

Yes it could be so. I really don't know. I did some experimenting with ground batteries some years ago.
I used Zinc and Copper plates in the ground. I found that the ground battery works but the output was
very low. I did compute that if I wanted any real power (to use a heat, light etc.) then I would have to
make my batteries cover a football field. I do not know if a earth battery is improved by coiling etc.
because I have never tried that.

Anyway, I did measure the frequency of my circuit. I put a pickup antenna close to the circuit and used my spectrum analyzer to see the output. My center freqency is close to 2MHz.

[EDIT] I did measure 62,5 KHz with my scope. So the 2MHz is an over harmonic oscillation.
          I'm sorry for my mistake.

2MHz, What is mean ? I never use the osciloscope and I am still limited in my knowledge of electronics.
I'm just do it with my lovely bread board

Is it oscilating frequency... ?

Oops , it's out of area harmonize , 30 Khz --- 350 Khz     

I forget to tell, 1200 mm length of coil , it's not exactly must follow,  i'm just fill the toroid )
i don't know the formula.

"Joule Thief" makes switch on and off about 50,000 times a second (50Khz). It's within that harmonize area. Maybe they don't know "the harmonize area"

Please find oscilating frequency in that area, 350 Khz is the best efficient

@zon,

It means that the oscillator runs with 2 million pulses each second. Those pulses create radio waves.
Those radio waves can be picked up with an antenna and sown on a frequency spectrum display.
My frequency spectrum display is connect to my computer so that I can "see" all the radio waves
in a graphic chart. The strength of the signal is at left on the graph and the frequency at the bottom.
The stronger the signal the higher up the graphic will go. It is measured in dBm (decibels over Milli Watt).

[EDIT] It is the frequency of the oscillator. I'm not sure if your low frequency is better. For the first time in my 5 year long research into free energy (and in my 40 years of playing with electronic) have I seen something that I find amazing! I have never before seen a LED being light up from a "dead" battery. The voltage stays the same and the circuit just keep going and going and going........... 

[EDIT] I found that the oscillator runs at 62,5KHz and the 2MHz I saw on my spectrum analyzer was an over harmonic oscillation frequency. I'm sorry for my mistake!

Hi Groundloop,

With highest respect but I cannot help but notice: dBm is decibels over Milli Watt and not volt, ok?  (See your link too.)  When you see using symbol dBu, it surely means decibels over microVolt but here the V symbol is usually omitted just like the W symbol in case of dBm, right?

@gyulasun,

Yes, you are 100% correct.

[EDIT] Circuit still running.
