Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

[resonanceman]

I got my  coil  finished  enough  to  test.

I still  have  some  things to do .   like  cut the  copper  winding  shorter.
I am going to  try to  match the  inductance with the  iron  winding .

I am going to wait  a few days ...........mostly because my thumbs hurt




I learned  alot about how NOT to wind  a coil ....

one of the  things  I wanted to test is   if  bigger wire is better.

I used   # 6 copper   
I got  some  Iron  wire for tying  rebar
I made a cable   with 12 strands .  It was a little oversized .. I think I would use 10 strands next time .

I am thinking that  larger wire  has less resistance .......so  the small  currents   generated  will carry through  easier . 
I was shooting  for  a cable of iron wire about the size of the insolated  copper
I wanted the  iron larger  because  it is higher resistance , ......

I see that my voltage is low compared to others .
I think that may  be in part that my outer windings are pretty loose .

If you can't  read the meter the voltage I got was  .54 V

Sorry about your thumbs. 
I'm confused.  Is the larger wire more resistance, or the smaller wire?
I found things went faster (setting up something to revolve around..did not measure output) when I used thinner wire, but I didn't think about the length of it.  However I remember someone else mentioning cutting the wire shorter and he got better voltage.  Do you mean by larger, thicker, or longer?  Or could it be both?
Are you wanting more resistance?  What does this achieve?
Interested,

this  was one of my posts before I changed my name here.

The  copper  for my coils  was  25 ft  of #6  wire .....usually used for ground  wire for  electrical  boxes  and  things like that.



As I undersand it   ........any  voltage will travel farther  in a larger diameter  wire than in a smaller one .......... 
I am  not  sure if larger  wires  will pick up more energy in an earth battery ...... I am guessing they will
Also ..... with the galvanic  reactions going on ......a large wire will last longer than small wire.

I see  I ididn't  explain  things  very well ..........I said .

I wanted the  iron larger  because  it is higher resistance , ......

What I meant by this ......... Iron  has alot more resistance than  copper ....... to make  up for this ......I wanted to  make the  iron wire larger diameter   to help lower the effective  resistance a little . 


I also  tried  to  trim the copper wire  to tune  the windings to the same  inductance ........ it turns  out both wires went down in inductance  when I trimmed  the copper.

@ Chad:

Nice readings!  I began checking the cell within an hour of fully burying it.  One thing I did notice, it took me a while, when I left the test leads hooked up and walked away for a bit...the vdc kept increasing, little by little, bit by bit.  I got my best readings after being hooked to the meter for about 30 minutes.  Once I checked the mA, which was very high for me, then the volts were back down a bit, but came back as before, over time.

Bill

PS:  I just checked again and, for a brief moment, I saw 69 mA on the meter!  This dropped quickly to about 57.  I hooked the positive lead to my carbon rod and negative to the core of the Stubblefield cell and read 1.3 vdc.  Funny, hooked up this way, the mA's were below 10.  I am able to add the volts but, this is hooked in parallel this way, not series so the mA's should go up not the volts!!!!!  I have no idea what is going on out there.

Thank you Gary.  That makes sense.  My thinner wire (Cu) did not do so well in another experiement over the long run, so you're right about lasting longer.  I'm learning alot here.
Now , have any of you done this around something that involves movement and got different readings?  I keep wondering about that tree.  It has sap and water, and osmosis and diffusion involved...  You've got me thinking.
Second, do any of you know the type of soils you are working with and are marking these down?  There are shapefiles available through many university GIS sites and state GIS sites, and even Country GIS sites.  Many of them are free.  You can get a free 60 day version of GIS from www.esri.com >go to products>go to ArcView> find free 60 day version and fill out the info.  They have sent me 3 of them without question (they know I'm a student though)  and they include discs to teach you the basics of using it.  It would be great if you added that data to your experiment so you would know the soil type, then you could look up that type and know the metals in those soils.  Some are aluminum rich esp in rain forest areas, some are high in iron, like Georgia.  Would this help?  If you need anymore info on GIS just send a note.  I'd be glad to help.

@ Bill
I see you got 1.3v Ac reading on the cell you buried, thats pretty good.

How are the readings progressing, are they going up, are even or falling over the last few days?


I just hooked some fishing line to my spring and tensioned it.
Having done this, I think the spring is way to strong, if so, I'll replace it with a re-verb spring.we shall see.

Over the weekend I made a driver coil, using ultra fine copper wire I took off a 12v horn relay coil.
I wound 430 turns on a 1/32" steel wire as the iron pole (couldn't find a small enough nail)

I have glued all this together so tomorrow I'll test it out and see if it will work.

@ Jim:

Yes, but that was with my one carbon electrode in the mix.  The plus from my carbon rod was tied to the copper lead on my coil, and the minus was the iron core.  Otherwise, just the coil alone was .93vdc.  Alone it gave the best mA readings also.  Good luck with your experiments.  I can't wait to see how they turn out.
