hi there kukulcangod

about getting more current or voltage I have my setup wired in paralel so im getting more current on each plate the size of the corucatted iron sheets are 8 meters 50 cm by 3 meters 70 cm was getting 9.00 ma it's dropped to about 6.00 ma

the jule theif still works if a battery is used  I think the circuits they have in the solar garden lights are designed to use a lot less current so thats good for us all have

managed to get four white leds going with the jule thief your right there about using more plates in the ground wish I could find flat sheets of copper back this way as with more surface area on the positve plate would most likely see a big

improvment. also back this way I use about 10 turns on my jule thief just use the standared jule thief circuit this way have also found that the first try I had the white leds I was using would not work i had tryed to use one red and two white leds as thats all I had at the time was a dud had success using all  red or all white.

@ All:

Here is my latest earth battery video:

Here I am lighting seven 10mm, high output leds. (28,500 MCDs each)  Each has a forward voltage of 3.5-4.5 volts at 40 mA's.  I am using a basic joule thief circuit and 2 supercaps. (10 Farad each)

To see the wiring of this earth battery, you can check out my 2 earlier videos on my new battery set-up.

Thanks.

So are you charging the supercaps with the JT that's running off your EB?  Sorry if the vid explained this I have no sound on this particular comp.

Ys, the caps are empty when I start.  I hook the earth battery to the JT circuit and the leds light.  While they are lit, the supercaps are also charging as well.  I can have them light for, say, 10 minutes, and disconnect the circuit from the EB and the leds stay lit for about 5 minutes or so.  That is how I know the caps are charging.

I am now lighting 100 leds from the earth battery:
