Does the Earth Have a Net Electric Charge, and Can That Be Tapped?

Very cool.  I look forward to reading that.  Have you ever tried my tree experiment with your DMM?  I wish more folks would.  I want to see if it is just my trees that are negative and the ground here is positive.  Maybe it is like this all over the world?  OR, maybe there are + and - trees?

Please folks, just try sticking one probe into a tree and the other in the ground.  If you get a - reading, reverse the probes and tell us what it reads.  My one tree out front is about 1 volt DC -.

Thanks Dave.

Hello Bill,

I tried your experiment today, I stabbed one probe into the tree root and the other as far away as I could into the ground. The ground read as positive and the meter read approx. 56 mv.

@RR2

try sticking the tree at a point higher up if you can, and notice the difference.

update:

the type/size of the tree may have something to do with it.

Large oak in the front yard was in the mv range,
   but the smaller flowering tree in the back yard reads 0.2v

just for shts n giggles i stabbed the wooden fence post and got nothing.....

Ive done that and have gotten voltage. If the ground is damp you should get voltage. The voltage decreased the further up I went on the post.

Could be just like wire. The longer the wire the larger the voltage drop.

I may try drilling a hole to the core on some oak or myrtle trees in my pasture. I have some that grow close to the bank of the pond also.
