On April 15, 2007 as part of an off-list discussion of Nikola Tesla's system 
for the transmission of electrical energy without wires, Gerry Reynolds 
noted that while creating a mathematical model which is representative of 
the Tesla wireless system, "areas of uncertainty will arise during this 
process and then we can agree on where the uncertainty is and propose 
experiments to empirically answer those questions."  At this point in the 
discussion some areas of uncertainty are,

     1) To what degree are grounded Tesla coil transmitters sources of radio 
waves in the far field zone?

     2) If the vertical cylindrical conductor between the top turn of the 
helical resonator up to the elevated terminal is shortened and at the same 
time the resonator itself is lengthened, how are far-field radio wave 
missions effected?

     3) Does Maxwell's theory accurately predict the degree of electrostatic 
coupling when the spacing between the two elevated terminals of a Tesla coil 
transmitter and a Tesla receiving transformer pair is more than a few 
wavelengths?

     4) If it were possible to ionize a path from Earth's surface to the 
upper troposphere, what power and wavelength UV laser would be required?

     5) How much power would be required to maintain ionization in the 
troposphere between transmitter and receiver, assuming that this portion of 
the path can somehow be ionized?

     6) Does Earth resonate at a frequency of not more that 12Hz that 
corresponds with a theoretical terrestrial resonance frequency of 11.787 Hz?

Questions #1 and #2 can be answered by testing the emissions of various 
Tesla coil transmitters following the guidelines set out in "FCC Methods of 
Measurement of Radio Noise Emissions From Industrial, Scientific, and 
Medical Equipment."

Question #3 can be answered by extensive signal strength measurements using 
the experimental apparatus described in #3 below.

Addressing question #4 will require the experimental apparatus described 
below and various UV radiation sources.

Here is Dr. Tesla's generalization in regards to question #5:

     "As to the influence of rarefaction upon the electric conductivity 
imparted to the gases it is noteworthy that, whereas the atmospheric or 
other gases begin ordinarily to manifest this quality at something like 
seventy-five millimeters barometric pressure with the impulses of excessive 
electromotive force to which I have referred, the conductivity, as already 
pointed out, begins even at normal pressure and continuously increases with 
the degree of tenuity of the gas, so that at, say, one hundred and thirty 
millimeters pressure, when the gases are known to be still nearly perfect 
insulators for ordinary electromotive forces, they behave toward 
electromotive impulses of several millions of volts, like excellent 
conductors, as though they were rarefied to a much higher degree." [SYSTEM 
OF TRANSMISSION OF ELECTRICAL ENERGY, Sept. 2, 1897, U.S. Patent No. 
645,576, Mar. 20, 1900.]

Dr. Tesla used an artificial atmospheric pressure of 135 mm Hg in a 
sectional 50-foot long evacuated glass tube to collect data about the 
properties of air plasma.  Note that the rarified gas inside of the 3" 
diameter sectional glass tube was plain air.  No other substances such as 
mercury were added as that would have altered the air's conductivity.

     "I took a tube 50 feet long, in which I established conditions such as 
would exist in the atmosphere at a height of about 4 1/2 miles, a height 
which could be reached in a commercial enterprise. . . . Then, on the basis 
of the results I had already obtained, I established those conditions, 
practically, in my laboratory.  I used that coil which is shown in my patent 
application of September 2, 1897 (Patent No. 645,576 of March 20, 1900), the 
primary as described, the receiving circuit, and lamps in the secondary 
transforming circuit, exactly as illustrated there.  And when I turned on 
the current, I showed that through a stratum of air at a pressure of 135 
millimeters, when my four circuits were tuned, several incandescent lamps 
were lighted."

An answer to question #6 will require considerable resources that might be 
brought to bear if a large group of people come together with this common 
vision.

To begin answering the above questions the collection of performance data 
using the following experimental apparatus is required:

1) A system for one-wire transmission between a Tesla coil transmitter and a 
Tesla coil receiving transformer with ground for return.

2) A system for electrical transmission between a Tesla coil transmitter and 
a Tesla coil receiving transformer through a partially evacuated glass tube 
with ground for return.

3) A system for wireless transmission between a Tesla coil transmitter and a 
Tesla coil receiving transformer with ground for return.

The following is a general description of an experiment that can be 
performed with apparatus #3.

First, place a tuned Tesla coil transmitter and Tesla coil receiver pair at 
a distance exceeding a few wavelengths and put the system into operation to 
demonstrate its functionality.

That radio waves are not involved in the transfer of energy (to answer 
question #1) can be shown by testing the emissions of the Tesla coil 
transmitter following the guidelines set out in "FCC Methods of Measurement 
of Radio Noise Emissions From Industrial, Scientific, and Medical 
Equipment."  If the Tesla coil transmitter is found not to be a radio wave 
emitter then the connection between the Tesla coil transmitter and the Tesla 
coil receiver must be by some means other than radio waves.

The radio wave emissions testing is to be done using a conventional radio 
receiver that is tunable to the Tesla coil transmitter's operating 
frequency, and which is sensitive only to radio waves.  The radio wave 
receiver's antenna must be configured in such a way so that it interacts as 
much as possible with radio waves and as little as possible with the 
non-radiating emissions of the Tesla coil transmitter.  Some appropriate 
antennas for this purpose are the vertical 1/2-wave dipole antenna suspended 
high above the ground to minimize capacitive coupling to the earth, the 
tuned air loop antenna, and the tuned ferrite loop-stick antenna.  A 
conventional radio wave transmitter connected to a dipole antenna as 
described above should be used to test the efficacy of the standard radio 
wave receiver.

The basic assumptions behind this comparative study of a conventional radio 
transmission-reception system and a "Tesla wave" transmission-reception 
system are as follows:

1) The emissions associated with an operating Tesla coil transmitter are 
predominantly non-radiating with reduced emissions in the form of radio 
waves.

2) Radio receivers connected to conventional non-grounded or 
non-counterpoise radio antennas are more sensitive, to a degree yet to be 
determined, to radio waves than they are to the non-radiating 
electromagnetic field energy associated with an operating Tesla coil 
transmitter.  Non-grounded radio antennas can be constructed, the 
performance of which approach that of the ideal radio antenna.

3) Grounded Tesla receiving transformers are more sensitive, to a degree yet 
to be determined, to the non-radiating energy associated with an operating 
Tesla coil transmitter than they are to radio waves.  Grounded Tesla coil 
transmitters and Tesla coil receivers can be constructed, the performance of 
which approach the ideal in both cases.  Radio transmitters with tuned 
grounded or ground plane antennas are also capable of emitting the form of 
electrical energy associated with an operating Tesla coil transmitter and 
that radio receivers with this class of antenna are also capable of 
collecting the predominant form of electrical energy associated with an 
operating Tesla coil transmitter.

It follows from this, if the energy from an operating Tesla coil transmitter 
is well collected by a Tesla receiving transformer, but is not well 
collected by a radio receiver connected to non-grounded or non-counterpoise 
radio antenna, while at the same time the radio receiver does well collect 
energy from a radio-wave transmitter connected to non-grounded or 
non-counterpoise radio antenna, all of these operating at the same 
frequency, then the electrical energy from the Tesla coil transmitter that 
is well collected by the Tesla receiving transformer is not predominantly in 
the form of radio waves.  If this is found to be true, the cause-and-effect 
relationship will shed some light on question #3.
