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

[jeanna]

I want to report another interesting thing.

I left for 3 days and this time I kept all the circuits going while I was gone.

The phyllis replication is still going strong with a steady red led.
It stopped flashing last week sometime 10 days ago, perhaps and it is still steady.

The Plant battery #1 was out but I only had to move the 3 inch stub end of magnesium back into the soil and it has been lighting both of its leds all evening.

The other 2 are in similar plastic boxes.

One was blinking and it is still blinking, no matter what I do.

The other one originally gave so much mA that lidmotor made one like it and ran a bobbin bedini with it which I replicated.
I cannot get that one to go on.
Last week after prodding it for a while it went on and got brighter the second and third days and was very hard on the eyes.

The only difference between these is that the one which is now flashing has a lot of extra magnesium lose in the soil and this one which will not turn on does not.
So, perhaps the magnesium does replenish the mag in the ribbon.
I am still not convinced, but here is another thing:

The outside one which in the video I show having a ditch of dolomite for the bed of the ring of magnesium wire, was still on when I got there and still on when I left.
That is a really long time.

Hi all   sorry for not being around. i have been busy going to court about a house i own. the lawyer, contractors and work has kept me from doing any testing. i just hope it ends soon. i will try when time is available for more testing.

i also need to repair my modified solar garden light. it's used for a night light in the bath room. i just need to replace the circuit board for now.

I also wanted to let you all know that my lights are still on and working my voltage is down to 1.09 volts but it has been on since 4/4/2010. i am sure the voltage will come back up if i was to water it.

also i was thinking i would try a cell in a tub of pulled up weeds for composting. it would stay wet, put off heat, and may be make some power at the same time. please tell me what you think about this.

Pardon:

This is great news!  Nice work over there.

I hope things work out with your house.

This is great news.
How long and what gauge are the wires you used?

I only have 1 still going from back then which needs nothing but water.
I am doing a little study on how long the wires are etc.
Please do you remember how long the 2 wires are?

I love this idea.
There is a guy called theremart at the EF who has been working with compost.
I think this is a great place to experiment.

And good luck with the lawyer junk,

Hello Jeanna and All..
I'm a novice in the joule thief art, and I have to power some leds,but until now I had no success.I have tried a basic circuit found on the web,rated for only on led, but didn't worked with 10 led put in parallel.I have to build a trap for the tomato moth,and I have to power ten  5mm 3Volts Ultraviolet leds put in series.The earth battery seems a good solution, because the trap is far from my house . I have a couple of  ultracaps rated 20 Farad 2,5 Volts.Can you suggest me a circuit that accomplish this task?
Thanks for your time....
