Earth Electrical Energy Datalogging Experiments

[sm0ky2]

i just replaced my "experimental electrodes" with similar ones made from copper wire and got very little voltage (0.05v)

so my set-up only works with the differing metals. in my case it is steel wire vs copper.

i have not yet ruled out some sort of galvonic reaction in my particular set-up, at least for the voltages above 0.6 that i get from the standard "EB" arrangements i have made thus far.


umm.. i thought i described it thoroughly before, but ok..

"parallel" meaning all wires are connected to the negative terminal of the "EB"

in reference to the above video,
i scratched the oxidized layer off of a soda can, and placed my meter between the can and a piece of copper wire sitting on my desk.

reading:  0.5v

copper/alum battery,  i think this was invented by alejandro volta some 209yrs ago??

So you twirled the wires and scraped the ends then you put one end of each of them into the ground and the other end of all of them together onto the copper probe?

Nothing extra is connected to the steel pipe? Only 30 of these things that are very small as things go maybe 1-2 inches total spiral length?

Then in between the 2 wires that connect the steel pipe to the copper with the expels you stuck a joule thief and you can light 30 leds (i am sure these are parallel)

Is this how you are doing this?

I do not think yours could be galvanic.
Just a tiny bit.
for some reason you need to have a touch of galvanic with all the magnetic earth currents to make the thing do work. But earth batteries are mostly not galvanic, I am sure of that.
(I am not talking about putting a plastic cup in the ground with electrodes in it. I am waiting to see about that.)

Thanks. please confirm my explanation.

btw, my Cu or C ar both the pos side of my battery . the steel is the neg.

ok i dont understand what you're saying..
i'll try again::

copper is the positive side of my battery. 3x   6-inch square copper plates tied to the + lead. (bottom end stuck in the ground)


the steel pipe and all the coiled steel wires are connected to the - lead. (bottom ends stuck in the ground)
between the + and - is placed the load. This is where the joule thief goes.

by themselves: (with respect to the copper lead)
2-ft stainless pipe gives me 0.68v max
2-inch coiled steel wire gives me 0.98v max



so far all my LEDs are light up across the transistor. if i connect ANYTHING to the secondary of the joule thief, the current draw is too much for the EB and all my LEDs go out. So, at this point the secondary of my JT is just open ended.

Thank you Sm0ky2, I have it, now! 

I better get something to cover the steel wire I have so I can try this. I dunno, it just might be a breakthrough.

Thanks,

jeanna
