The surge that you have seen in your earth battery setup could very well have been a telluric spike.  It fits the characteristics of one.  Whats the frequency of the spikes?  I read that they occur somewhere between 5-6 mins i cant recall the source though atm. 

I have read some interesting info in regards to what is being experimentally shown.

In Earth's Electrical Environment (1985 or 1986 published ).  In the section on telluric currents it notes of 2 types of telluric currents.  Shallow and Deep.  Shallow telluric currents are exhibited due to difference between the geomagnetic field of the earth and the position of ocean currents or conductive medium in the soil layer ( ie mineral deposits ).  Deep currents are independent of geomagnetic field and tend to occur during tectonic activity.   

@IotaYodi    I agree the mountains have alot to do with the output of EB's.  Differences in ground potential, altitude and proximity to propagation areas of telluric currents ( old fault lines ) .  Tesla made some mention of this during his Colorado Springs experiments, and before Wardenclyffe his parameters for a wireless communication network included a high-altitude station,  some of which were balloon elevated.  Just food for thought.

Also to make note as I just thought of this,  one of the reasons that EB's perform really well around the roots of trees is possibly due to the tree itself.  Now this is commonsensical, but what does a root system of any plant do?  Suck in water, now if it just happen to suck in some water past our EB exciting it via galvanic reaction,   well that is just purely beneficial for us

oh and if you are picking up ground leakage,  some easy ways to test are checking its electrical frequency and its waveform ( sine ) 

Quoteparameters for a wireless communication network included a high-altitude station,  some of which were balloon elevated.

This would be more line of sight rather than the gain of power. The higher you go the further the distance a signal can be sent.

Quoteis possibly due to the tree itself

The capillary system of the tree itself would become part of the circuit. This would also include the leaves. The telluric currents also travel through trees and plants. Plus you have an electrical potential of 100 volts per vertical meter. A 25 foot tree would have about an 800 volt potential. I would think that NS used the trees as the negative.  Experiments should be done with both dry and wet trees of different heights with an NS coil. A tree with thicker bark might be a better conductor.

@all

Don't forget that Tesla wireless system was in fact not aerial but better illustrated as earth being the wire , in a single wire system .

What is common to all electric system  ... Ground !

Is there someone on the receiving end ...

Only in part in my mind. The Earth may have completed the circuit but with the power generation being transmitted through the air.
