Ok thats what i thought originally i was just trying to understand.


This is in reference to the electromagnetic self sustaining model

A microphone or telegraphic relay would modulate the secondary coil in turn stepping down voltage and upping the current in the primary which would in turn send that modulated pulse through the bolt into the earth.

The bolt being polarized like a magnet since this version states that in the patent must serve a purpose..The bifilar coil is most likely to act as the capicator. See tesla's ozone patent

maybe over saturation of the core results in the magnetic energy going elsewhere.  Meaning more energy coming in to the core that was present from the shorted bimetallic couple.

This is exactly along my lines of thinking, the earth is being charged. I don't think the earth by itself will give you any useable charge, you need an antenna for a postive and a big grounding plate for a negative isolated from each other and the coil acting as a tank or capacitor to hold and build the charge. We all know a capacitor has two sides a + and a minus - and the earth is the minus and the air is the plus. I honestly don't feel your going to be able to take two minus and make it work any more than you can make a magnet with two South poles. Not meaning to sound negative, just my way of thinking.

I think there is something going on that the digital meters are not going to pick up. I made a galvanometer last year. It is 60 wraps of varnished mag wire around a compass with the ends sanded and separated for connections. It reads electrons flowing through its wires by a change in the direction of the point of the compass. You can see the direction by the left hand rule and 'watch' the current.

I have had this out at moments but I have never seen much of a response with the earth battery so I almost missed this.

Of course this might have been the main tool someone in 1898 had to check current. So, anyway, it was on the table when I was taking pictures for records. I had to move it once and when I passed it over the spike it reversed polarity.  I am not using it as a galvanometer, just a compass, right now.

I took pictures and made records of the behavior of this compass around each of the 3 spikes I have made.

There is something happening that is changing the magnetic field around these spikes. And this is without any galvanic reax because they are all dry and there is no battery involved.

I will put this together and report tomorrow.

Hey all:

I will post a couple of pics.

15 mA!
.79 vdc
1.0ac

This was tested by simply wetting the cotton.  I am not done with it yet, just could not wait to see if it works, and it does.

This one is a close up.  Here you can see the single layer of copper, iron wire, insulated copper wire and cotton string.  All possible connections have no shorts to each other, or to the core.. I did not count the windings but it is as many as you can fit winding bifilar over 10" long coil area.  This is just the first layer.  Excellent results here Joe.  Anyone can replicate this.  I believe I am getting the exact same readings a you did Joe. (or very close)  I also read .25 vdc dry, just sitting on my table.  I can't wait to finish this and stick it in the ground.

@ Joe:

You were correct.  I did a quick test while seeing if the new cell works.  I noticed that in a dead short on mA readings on the meter, they seem to slide off slowly.  Much more slowly than my other earth cell set-up.  But, as fast as you can disconnect/re-connect the test probe, it is right back to 15 mA.  It is like instant recovery.  Probably a very useful feature for priming the secondary don't you think?  Man, if we used a secondary winding of a few thousand turns, we will probably get knocked on our ass testing the things. Ha ha.
