EER Joule Thief using an earth battery to start a joule thief.

[kb24]

Hi,

I am new member in this forum. I am currently working on a project about earth battery. I am using a 2cm x 10cm plate of copper and zinc. My reading was 0.8V and 0.1mA per cell.

After reading so many post, i found out that joule thief can be used to power up my earth cell, so i make a joule thief from tutorial on youtube. But the joule thief i use can be only used on battery and not earth battery. May i know why?

And i read from earlier post that lightsaber has done a joule thief for earth battery. May i know the how to build it?

Good Morning everyone
I have been working with earth batteries for most of the sommer and fall and recently came across the idea of a jule thief.
I built a joule thief and it works well on just a battery. However when i hook it up to my earth battery the voltage actually goes down from .899 volts to .458 volts. Does any one have any idea what direction i can go to correct this?
Let me know.
thanks
Scott

Add more Earth cells in both series and parallel to up the voltage and amps. You could also upgrade the materiel's as well as their size. A small common copper and zinc setup doesnt put out many milliamps. Check out the difference in amps of the dry cell compared to the earth cell.

@ All,  I am testing a joulethief powered by 1x AA rechargable battery with 1x LED lit + charging a supercap,
          and I left it on overnight and I lost  4 mV on the run battery, but gained 192 mV on my supercap.

          Is this overunity by any chance ?

          I will be doing more experiments.

          Sorry I know this does not belong in this thread, but I wondered why all the main members seem to
          have left the joulethief thread !

@freepow, I am NOT posting this to scold you or anybody.
It sort of sounds that way, so sorry. I mean NO unkindness. 


I don't know why anybody uses the wrong thread knowingly.
that happened early on with this thread.

If I recall, this thread is about using an earth or plant (potted inside) battery to run a jtc.
It requires a pretty good jtc because the amperage in a plant battery is very low.

So, this was supposed to be a thread about getting the right amounts and parts together so anybody anywhere in the world with very little resources could have a light.

I think it was hard for people to keep from diverging, so when I accomplished what I was after, I stopped posting.
That is all recorded and anyone who wants to can look it up.

I don't mind repeating myself a little, because I still remember when others gave me that courtesy, but I am busy with other things and all that anybody needs is already posted somewhere around here.

About self running circuits, check out lasersaber's ringer or kooler's captret threads on the joule thief forums.
There is plenty to encourage and work with over there.
