@ Yaz:

Great link!  This appears to me to be combining both the earth battery (telluric currents) and the interception of radio waves in the air, both man made and natural.  His voltage output was impressive.  We will have to add this into the mix and see what the experimenters can do.  Have you tried any of this yet?  Can you invite the guy from that link to our topic here?  The more minds and ideas, the better.

G'day all,

Here is something I found on Tesla that is relevant. This is clearly about the project he was running with Stubblefield.

Tesla vs. Hertz

Tesla was not a theoretician by calling, but he made plenty of observations on the electrical nature of the universe that put him at odds with of official theory. In fashion then (and even now) was the theory of Heinrich Hertz, an interpreter of the physics of James Maxwell. Hertz explained radio propagation as transverse waves akin to light. Tesla was convinced that radio disturbances were standing waves in the ether akin to sound. When you drop a pebble into water, the disturbances you see in the form of concentric circles are standing waves.

Both Tesla and Hertz assumed the existence of an aetheric medium, but differed as to its energy transmitting properties. Tesla believed that the ether was a gas like medium, that electric propagation was very much like that of sounds in air, alternate compression's and rarefaction's of the medium, and that Hertzian waves could only take place in a solid medium. Tesla once said that Hertz waves are radiation and that no energy could be economically transmitted to a distance by any such agency. He said, In my system, the process is one of true conduction which can be effected at the greatest distance without appreciable loss.

When quantum physics and particle theory came into vogue, the aetheric medium was dropped out of electric theory altogether, but Hertz's theory was more compatible with the new concepts of propagation and therefore survived. By way of rubbing this in, the unit of frequency, formerly cycles per second (cps), was renamed in honor of Hertz (Hz), while only an obscure unit of magnetic flux density remembers Tesla. It is in respect to Tesla that I have reverted to the old unit in this book. Hertzian radio is straight-line, light-like radiation's that bounce off hills and mountains. Long distance Hertzian transmissions are explained in terms of radiation's bouncing off a radio reflective upper layer called the ionosphere. Tesla thought this was all nonsense and declared in 1919 that Hertzian thinking has stifled creative effort in the wireless art and retarded it for 25 years. Hertzian radio is aerial.

Most of us are conditioned to thinking in terms of aerial radio; the air waves, on the air. Tesla's radio is grounded; the lower end of the energized coil is rooted in the earth. Pure Hertzian radio has no such natural load. Tesla doesn't speak of antennas as such; the element he places aloft is an elevated capacity. Tesla said radio devices should be designed with due regard to the physical properties of this planet and the electrical conditions obtaining in same. Grounded radio is indeed more powerful than the Hertzian aerial. But this is true particularly for the frequencies Tesla was using. The higher frequencies do behave in a Hertzian manner. Yet grounding is all but a lost concept in consumer electronics. Up through the 1940's, AM radio receivers customarily had a terminal one was encouraged to connect to a cold water pipe or other deep earth connection. Ground the chassis of any of today's receivers, and, unless there is some kind of interference coming up through the ground (from fluorescent circuits, light dimmers, which are oscillators, or from the local Tesla coil), you will usually improve signal strength and range.

Among Tesla's contributions to radio was remote control. Tesla demonstrated a radio-controlled boat before crowds at Madison Square Gardens and sent another robot craft 25 miles up the Hudson River. Grounded radio works particularly well through water. Tesla's basic radio tuning tank circuit for receiving (coil plus capacitor between antenna and ground) was, and is, all by itself, a powerful signal amplifier, and a beautifully simple one, at that. But as radio developed over the years, the tank circuit shrank in size and the result was a loss in gain. This was compensated for by the addition of stage upon stage of complex amplification circuitry.

Tesla watched this development with bewilderment. Tesla knew that the most efficient long-distance radio took place in the lower frequencies, especially those close to the earth-resonant frequency. Frequencies well below the AM broadcast band were the favored ham frequencies in the early days prior to World War I. In fact, waves of 600 meters (500 kc) were considered short while considered fairly long were the waves of 1200 meters (25 kc). Like a lot of good real estate, many of these more radio-effective frequencies below the AM broadcast band have been appropriated for military use, but also for navigation beacons, weather stations, and time registers.

EDIT: On another page on the same website:

These are the words of Nikola Tesla, spoken in 1937; (part of a larger speech)

One of my most important discoveries--terrestrial resonance--which is the foundation of wireless power transmission and which I announced in 1899, is not understood even today. Nearly two years after I had flashed an electric current around the globe, Edison, Steinmetz, Marconi, and others declared that it would not be possible to transmit even signals by wireless across the Atlantic. Having anticipated so many important developments, it is not without assurance that I attempt to predict what life is likely to be in the twenty-first century.

@ Hans:

Once again, excellent information, thank you.  From what I have read of Tesla, the earth can and does act as a meduim for signal transmissions. (ie energy?) It is very interesting to me that he knew, even then, the resonant freq. of the earth. (very low)

@mramos:

I agree.  I have been following the Stiffler experiments and have always been wondering how we can tie this to the earth battery experiments we are working on here.  Please let us know of your results.  There are a lot of good minds here and I think we can get a handle on this thing before too long.

It is no surprise to me that Tesla knew the what is called now resonant frequency of earth about 7.8 Hz (Schumann resonance). With his earthquake machine he would have had to go much. much lower than this to cause the effects he did.

I seriously doubt though that Tesla was referring to the Schumann resonance.

According to Wikipedia: The fundamental mode of the Schumann resonance is a standing wave in the Earth-ionosphere cavity with a wavelength equal to the circumference of the Earth.

I think that Tesla was referring to the resonnant frequency of the ENTIRE MASS OF THE EARTH, which would have to be much lower.

How he cottoned on to this and how he measured it with the instruments of the day is an enigma to me.

Hey Guys!
  Interesting topic. I was doing some in-depth reading on earth battery experiments awhile back and I remember that they,
( I don't remember who), were sending a charge into the ground to get it going- like a syphon I guess. After that they would get a greater charge that would keep giving and get larger with time. I don't know if it works or helps but I thought i'd mention it.-JT
