<p> Abstract</p>

<p> Many researchers have speculated on the meaning of the phrase "non-<ent type='PERSON'>Hertzian</ent> waves" as used by Dr. Nikola <ent type='ORG'>Tesla</ent>. Dr. <ent type='ORG'>Tesla</ent> first began to
use this term in the mid 1890's in order to explain his proposed system
for the wireless transmission of electrical power. In fact, it was not
until the distinction between the method that <ent type='PERSON'>Heinrich Hertz</ent> was using
and the system Dr. <ent type='ORG'>Tesla</ent> had designed, that Dr. <ent type='ORG'>Tesla</ent> was able to
receive the endorsement of the renowned physicist, Lord <ent type='PERSON'>Kelvin</ent>.1</p>

<p> To this day, however, there exists a confusion amongs researchers,
experimentalists, popular authors and laymen as to the meaning of non-<ent type='PERSON'>Hertzian</ent> waves and the method Dr. <ent type='ORG'>Tesla</ent> was promoting for the wireless
transmission of power. In this paper, the terms pertinent to wireless
transmission of power will be explained and the methods being used by
present researchers in a recreation of the <ent type='ORG'>Tesla</ent>'s 1899 <ent type='GPE'>Colorado</ent>
Springs experiments will be defined.</p>

<p> Early Theories of Electromagnetic Propagation</p>

<p> In pre-<ent type='EVENT'>World War</ent> I physics, scientists postulated a number of
theories to explain the propagation of electromagnetic energy through
the ether. There were three popular theories present in the literature
of the late 1800's and early 1900's. They were:
1. Transmission through or along the <ent type='LOC'>Earth</ent>,
2. Propagation as a result of terrestrial resonances,
3. Coupling to the ionosphere using propagation through
electrified gases.</p>

<p> We shall concern our examination at this time to the latter two
theories as they were both used by Dr. <ent type='ORG'>Tesla</ent> at various times to
explain his system of wireless transmission of power. It should be
noted, however, that the first theory was supported by Fritz
<ent type='PERSON'>Lowenstein</ent>, the first vice-president of <ent type='ORG'>the Institute</ent> of Radio
Engineers, a man who had the enviable experience of assisting Dr. <ent type='ORG'>Tesla</ent>
during the <ent type='GPE'>Colorado Springs</ent> experiments of 1899. <ent type='PERSON'>Lowenstein</ent> presented
what came to be known as the "gliding wave" theory of electromagnetic
radiation and propagation during a lecture before the IRE in 1915.
(<ent type='PERSON'>Fig</ent>. 1)</p>

<p> Dr. <ent type='ORG'>Tesla</ent> delivered lectures to <ent type='ORG'>the Franklin Institute</ent> at
<ent type='GPE'>Philadelphia</ent>, in February, 1983, and to <ent type='ORG'>the National Electric Light</ent>
Association in St. Louis, in March, 1983, concerning electromagnetic
wave propagation. The theory presented in those lectures proposed that
the <ent type='LOC'>Earth</ent> could be considered as a conducting sphere and that it could
support a large electrical charge. Dr. <ent type='ORG'>Tesla</ent> proposed to disturb the
charge distribution on the surface of the <ent type='LOC'>Earth</ent> and record the period
of the resulting oscillations as the charge returned to its state of
equilibrium. The problem of a single charged sphere had been analyzed
at that time by J.J. Thompson and A.G. <ent type='PERSON'>Webster</ent> in a treatise entitled
"The Spherical Oscillator." This was the beginning of an examination
of what we may call the science of terrestrial resonances, culminating
in the 1950's and 60's with the engineering of VLF radio systems and
the research and discoveries of W.O. <ent type='PERSON'>Schumann</ent> and J.R. <ent type='PERSON'>Waite</ent>.</p>

<p> The second method of energy propagation proposed by Dr. <ent type='ORG'>Tesla</ent> was
that of the propagation of electrical energy through electrified gases.
Dr. <ent type='ORG'>Tesla</ent> experimented with the use of high frequency RF currents to
examine the properties of gases over a wide range of pressures. It was
determined by Dr. <ent type='ORG'>Tesla</ent> that air under a partial vacuum could conduct
high frequency electrical currents as well or better than copper wires.
If a transmitter could be elevated to a level where the air pressure
was on the order of 75 to 130 millimeters in pressure and an excitation
of megavolts was applied, it was theorized that;</p>

<p> "...the air will serve as a conductor for the current produced, and
the latter will be transmitted through the air with, it may be, even
less resistance than through an ordinary copper wire".2 (<ent type='PERSON'>Fig</ent>. 2)
Resonating Planet <ent type='LOC'>Earth</ent></p>

<p> Dr. James T. <ent type='ORG'>Corum</ent> and <ent type='PERSON'>Kenneth</ent> L. <ent type='ORG'>Corum</ent>, in chapter two of their soon
to be published book, A <ent type='ORG'>Tesla</ent> Primer, point out a number of statements
made by Dr. <ent type='ORG'>Tesla</ent> which indicate that he was using resonator fields and
transmission line modes.</p>

<p> 1. When he speaks of tuning his apparatus until <ent type='PERSON'>Hertzian</ent> radiations
have been eliminated, he is referring to using <ent type='ORG'>ELF</ent> vibrations: "...the
<ent type='PERSON'>Hertzian</ent> effect has gradually been reduced through the lowering of
frequency."3</p>

<p> 2. "...the energy received does not diminish with the square of the
distance, as it should, since the <ent type='PERSON'>Hertzian</ent> radiation propagates in a
hemisphere."3</p>

<p> 3. He apparently detected resonator or standing wave modes: "...my
discovery of the wonderful law governing the movement of electricity
through the globe...the projection of the wavelengths (measured along
the surface) on the earth's diameter or axis of symmetry...are all
equal."3</p>

<p> 4. "We are living on a conducting globe surrounded by a thin layer of
insulating air, above which is a rarefied and conducting
atmosphere...The <ent type='ORG'>Hertz</ent> waves represent energy which is radiated and
unrecoverable. The current energy, on the other hand, is preserved and
can be recovered, theoretically at least, in its entirety."4</p>

<p> As Dr. <ent type='ORG'>Corum</ent> points out, "The last sentence seems to indicate that
<ent type='ORG'>Tesla</ent>'s <ent type='GPE'>Colorado Springs</ent> experiments could be properly interpreted as
characteristic of a wave-guide probe in a cavity resonator."5 This was
in fact what led Dr. <ent type='ORG'>Tesla</ent> to report a measurement which to this day is
not understood and has led many to erroneously assume that he was
dealing with faster than light velocities.</p>

<p> The Controversial Measurement;</p>

<p> It does not indicate faster than light velocity</p>

<p> The mathematical models and experimental data used by <ent type='PERSON'>Schumann</ent> and
<ent type='PERSON'>Waite</ent> to describe <ent type='ORG'>ELF</ent> transmission and propagation are complex and
beyond the scope of this paper. Dr. James F. <ent type='ORG'>Corum</ent>, <ent type='PERSON'>Kenneth</ent> L. <ent type='ORG'>Corum</ent>
and Dr. A-<ent type='PERSON'>Hamid Aidinejad</ent> have, however, in a series of papers
presented at the 1984 <ent type='ORG'>Tesla</ent> <ent type='EVENT'>Centennial Symposium</ent> and the 1986
International <ent type='ORG'>Tesla</ent> Symposium, applied the experimental values obtained
by Dr. <ent type='ORG'>Tesla</ent> during his <ent type='GPE'>Colorado Springs</ent> experiments to the models and
equations used by <ent type='PERSON'>Schumann</ent> and <ent type='PERSON'>Waite</ent>. The results of this exercise
have proved that the <ent type='LOC'>Earth</ent> and the surrounding atmosphere can be used
as a cavity resonator for the wireless transmission of electrical
power. (<ent type='PERSON'>Fig</ent>. 3)</p>

<p> Dr. <ent type='ORG'>Tesla</ent> reported that .08484 seconds was the time that a pulse
emitted from his laboratory took to propagate to the opposite side of
the planet and to return. From this statement many have assumed that
his transmissions exceeded the speed of light and many esoteric and
fallacious theories and publications have been generated. As <ent type='ORG'>Corum</ent> and
<ent type='PERSON'>Aidinejad</ent> point out, in their 1986 paper, "<ent type='ORG'>The Transient Propagation</ent> of
<ent type='ORG'>ELF</ent> Pulses in the <ent type='LOC'>Earth</ent> Ionosphere Cavity", this measurement represents
the coherence time of the <ent type='LOC'>Earth</ent> cavity resonator system. This is also
known to students of radar systems as a determination of the range
dependent parameter. The accompanying diagrams from <ent type='ORG'>Corum</ent>'s and
<ent type='PERSON'>Aidinejad</ent>'s paper graphically illustrate the point. (<ent type='PERSON'>Fig</ent>. 3 &amp; <ent type='PERSON'>Fig</ent>. 4)</p>

<p> We now turn to a description of the methods to be used to build, as
Dr. <ent type='ORG'>Tesla</ent> did in 1899, a cavity resonator for the wireless transmission
of electrical power.</p>

<p> PROJECT TESLA:</p>

<p> <ent type='ORG'>The Wireless Transmission</ent> of Electrical Energy Using <ent type='PERSON'>Schumann</ent> Resonance</p>

<p> It has been proven that electrical energy can be propagated around
the world between the surface of the <ent type='LOC'>Earth</ent> and the ionosphere at
extreme low frequencies in what is known as the <ent type='PERSON'>Schumann</ent> Cavity. The
<ent type='PERSON'>Schumann</ent> cavity surrounds the <ent type='LOC'>Earth</ent> between ground level and extends
upward to a maximum 80 kilometers. Experiments to date have shown that
electromagnetic waves of extreme low frequencies in the range of 8 Hz,
the fundamental <ent type='PERSON'>Schumann</ent> Resonance frequency, propagate with little
attenuation around the planet within the <ent type='PERSON'>Schumann</ent> Cavity.</p>

<p> Knowing that a resonant cavity can be excited and that power can be
delivered to that cavity similar to the methods used in microwave ovens
for home use, it should be possible to resonate and deliver power via
the <ent type='PERSON'>Schumann</ent> Cavity to any point on <ent type='LOC'>Earth</ent>. This will result in
practical wireless transmission of electrical power.</p>

<p> Background</p>

<p> Although it was not until 1954-1959 when experimental measurements
were made of the frequency that is propagated in the resonant cavity
surrounding the <ent type='LOC'>Earth</ent>, recent analysis shows that it was Nikola <ent type='ORG'>Tesla</ent>
who, in 1899, first noticed the existence of stationary waves in the
<ent type='PERSON'>Schumann</ent> cavity. <ent type='ORG'>Tesla</ent>'s experimental measurements of the wave length
and frequency involved closely match <ent type='PERSON'>Schumann</ent>'s theoretical
calculations. Some of these observations were made in 1899 while <ent type='ORG'>Tesla</ent>
was monitoring the electromagnetic radiations due to lightning
discharges in a thunderstorm which passed over his <ent type='GPE'>Colorado Springs</ent>
laboratory and then moved more than 200 miles eastward across the
plains. In his <ent type='GPE'>Colorado Springs</ent> Notes, <ent type='ORG'>Tesla</ent> noted that these
stationary waves "... can be produced with an oscillator," and added in
parenthesis, "This is of immense importance."6 The importance of his
observations is due to the support they lend to the prime objective of
the <ent type='GPE'>Colorado Springs</ent> laboratory. The intent of the experiments and the
laboratory <ent type='ORG'>Tesla</ent> had constructed was to prove that wireless
transmission of electrical power was possible.</p>

<p> <ent type='PERSON'>Schumann</ent> Resonance is analogous to pushing a pendulum. The intent of
<ent type='ORG'>Project</ent> <ent type='ORG'>Tesla</ent> is to create pulses or electrical disturbances that would
travel in all directions around the <ent type='LOC'>Earth</ent> in the thin membrane of non-conductive air between the ground and the ionosphere. The pulses or
waves would follow the surface of the <ent type='LOC'>Earth</ent> in all directions expanding
outward to the maximum circumference of the <ent type='LOC'>Earth</ent> and contracting
inward until meeting at a point opposite to that of the transmitter.
This point is called the anti-pode. The traveling waves would be
reflected back from the anti-pode to the transmitter to be reinforced
and sent out again.

At the time of his measurements <ent type='ORG'>Tesla</ent> was experimenting with and
researching methods for "...power transmission and transmission of
intelligible messages to any point on the globe." Although <ent type='ORG'>Tesla</ent> was
not able to commercially market a system to transmit power around the
globe, modern scientific theory and mathematical calculations support
his contention that the wireless propagation of electrical power is
possible and a feasible alternative to the extensive and costly grid of
electrical transmission lines used today for electrical power
distribution.</p>

<p> <ent type='ORG'>The Need for</ent> a Wireless System of Energy Transmission</p>

<p> A great concern has been voiced in recent years over the extensive
use of energy, the limited supply of resources, and the pollution of
the environment from the use of present energy conversion systems.
Electrical power accounts for much of the energy consumed. Much of this
power is wasted during transmission from power plant generators to the
consumer. The resistance of the wire used in the electrical grid
distribution system causes a loss of 26-30% of the energy generated.
This loss implies that our present system of electrical distribution is
only 70-74% efficient.</p>

<p> A system of power distribution with little or no loss would conserve
energy. It would reduce pollution and expenses resulting from the need
to generate power to overcome and compensate for losses in the present
grid system.</p>

<p> The proposed project would demonstrate a method of energy
distribution calculated to be 90-94% efficient. An electrical
distribution system, based on this method would eliminate the need for
an inefficient, costly, and capital intensive grid of cables, towers,
and substations. The system would reduce the cost of electrical energy
used by the consumer and rid the landscape of wires, cables, and
transmission towers.</p>

<p> There are areas of the world where the need for electrical power
exists, yet there is no method for delivering power. <ent type='LOC'>Africa</ent> is in need
of power to run pumps to tap into the vast resources of water under the
Sahara Desert. Rural areas, such as those in <ent type='GPE'>China</ent>, require the
electrical power necessary to bring them into the 20th century and to
equal standing with western nations.</p>

<p> As first proposed by <ent type='PERSON'>Buckminster Fuller</ent>, wireless transmission of
power would enable world wide distribution of off peak demand capacity.
This concept is based on the fact that some nations, especially the
United States, have the capacity to generate much more power than is
needed. This situation is accentuated at night. The greatest amount
of power used, the peak demand, is during the day. The extra power
available during the night could be sold to the side of the planet
where it is day time. Considering the huge capacity of power plants in
<ent type='GPE'>the United States</ent>, this system would provide a saleable product which
could do much to aid our balance of payments.</p>

<p> MARKET ANALYSIS</p>

<p> Of the 56 billion dollars spent for research by the the U.S
government in 1987, 64% was for military purposes, only 8% was spent on
energy related research. More efficient energy distribution systems
and sources are needed by both developed and under developed nations.
In regards to <ent type='ORG'>Project</ent> <ent type='ORG'>Tesla</ent>, the market for wireless power transmission
systems is enormous. It has the potential to become a multi-billion
dollar per year market.
</p>

<p> Market Size</p>

<p> The increasing demand for electrical energy in industrial nations is
well documented. If we include the demand of third world nations,
pushed by their increasing rate of growth, we could expect an even
faster rise in the demand for electrical power in the near future.</p>

<p> In 1971, nine industrialized nations, (with 25 percent of the world's
population), used 690 million kilowatts, 76 percent of all power
generated. The rest of the world used only 218 million kilowatts. By
comparison, <ent type='GPE'>China</ent> generated only 17 million kilowatts and <ent type='GPE'>India</ent>
generated only 15 million kilowatts (less than two percent each).7 If
a conservative assumption was made that the three-quarters of the world
which is only using one-quarter of the current power production were to
eventually consume as much as the first quarter, then an additional 908
million kilowatts will be needed. The demand for electrical power will
continue to increase with the industrialization of the world.</p>

<p> Market <ent type='ORG'>Project</ent>ions</p>

<p> The Energy Information Agency (<ent type='ORG'>EIA</ent>), based in <ent type='GPE'>Washington</ent>, D.C.,
reported the 1985 net generation of electric power to be 2489 billion
kilowatt hours. At a conservative sale price of $.04 per kilowatt hour
that results in a yearly income of 100 billion dollars. The <ent type='ORG'>EIA</ent> also
reported that the 1985 capacity according to generator name plates to
be 656118 million watts. This would result in a yearly output of
5740 billion kilowatt hours at 100% utilization. What this means is
that we use only about 40% of the power we can generate (an excess
capability of 3251 billion kilowatt hours).</p>

<p> Allowing for down time and maintenance and the fact that the night time
off peak load is available, it is possible that half of the excess
power generation capability could be utilized. If 1625 billion
kilowatt hours were sold yearly at $.06/kilowatt, income would total
9.7 billion dollars.</p>

<p> <ent type='ORG'>Project</ent> <ent type='ORG'>Tesla</ent>: Objectives</p>

<p> The objectives of <ent type='ORG'>Project</ent> <ent type='ORG'>Tesla</ent> are divided into three areas of
investigation.
1. Demonstration that the <ent type='PERSON'>Schumann</ent> Cavity can be resonated with an
open air, vertical dipole antenna;
2. Measurement of power insertion losses;
3. Measurement of power retrieval losses, locally and at a distance.</p>

<p> Methods</p>

<p> A full size, 51 foot diameter, air core, radio frequency resonating
coil and a unique 130 foot tower, insulated 30 feet above ground, have
been constructed and are operational at an elevation of approximately
11000 feet. This system was originally built by <ent type='PERSON'>Robert Golka</ent> in 1973-1974 and used until 1982 by <ent type='GPE'>the United States</ent> Air Force at <ent type='GPE'>Wendover</ent> AFB
in <ent type='GPE'>Wendover</ent>, <ent type='GPE'>Utah</ent>. The <ent type='ORG'>USAF</ent> used the coil for simulating natural
lightning for testing and hardening fighter aircraft. The system has a
capacity of over 600 kilowatts. The coil, which is the largest part
of the system, has already been built, tested, and is operational.</p>

<p> A location at a high altitude is initially advantageous for reducing
atmospheric losses which work against an efficient coupling to the
<ent type='PERSON'>Schumann</ent> Cavity. The high frequency, high voltage output of the coil
will be half wave rectified using a uniquely designed single electrode
X-ray tube. The X-ray tube will be used to charge a 130 ft. tall,
vertical tower which will function to provide a vertical current
moment. The mast is topped by a metal sphere 30 inches in diameter.
X-rays emitted from the tube will ionize the atmosphere between the
<ent type='ORG'>Tesla</ent> coil and the tower. This will result in a low resistance path
causing all discharges to flow from the coil to the tower. A
circulating current of 1000 amperes in the system will create an
ionization and corona causing a large virtual electrical capacitance in
the medium surrounding the sphere. The total charge around the tower
will be in the range of between 200-600 coulombs. Discharging the
tower 7-8 times per second through a fixed or rotary spark gap will
create electrical disturbances, which will resonantly excite the
<ent type='PERSON'>Schumann</ent> Cavity, and propagate around the entire <ent type='LOC'>Earth</ent>.</p>

<p> The propagated wave front will be reflected from the antipode back to
the transmitter site. The reflected wave will be reinforced and again
radiated when it returns to the transmitter. As a result, an
oscillation will be established and maintained in the <ent type='PERSON'>Schumann</ent> Cavity.
The loss of power in the cavity has been estimated to be about 6% per
round trip. If the same amount of power is delivered to the cavity on
each cycle of oscillation of the transmitter, there will be a net
energy gain which will result in a net voltage, or amplitude increase.
This will result in reactive energy storage in the cavity. As long as
energy is delivered to the cavity, the process will continue until the
energy is removed by heating, lightning discharges, or as is proposed
by this project, loading by tuned circuits at distant locations for
power distribution.</p>

<p> The resonating cavity field will be detected by stations both in the
United States and overseas. These will be staffed by engineers and
scientists who have agreed to participate in the experiment.</p>

<p> Measurement of power insertion and retrieval losses will be made at
the transmitter site and at distant receiving locations. Equipment
constructed especially for measurement of low frequency electromagnetic
waves will be employed to measure the effectiveness of using the
<ent type='PERSON'>Schumann</ent> Cavity as a means of electrical power distribution. The
detection equipment used by project personnel will consist of a pick up
coil and industry standard low noise, high gain operational amplifiers
and active band pass filters.</p>

<p> In addition to project detection there will be a record of the
experiment recorded by a network of monitoring stations that have been
set up specifically to monitor electromagnetic activity in the <ent type='PERSON'>Schumann</ent>
Cavity. </p>

<p> Evaluation Procedure</p>

<p> The project will be evaluated by an analysis of the data provided by
local and distant measurement stations. The output of the transmitter
will produce a 7-8 Hz sine wave as a result of the discharges from the
antenna. The recordings made by distant stations will be time
synchronized to ensure that the data received is a result of the
operation of the transmitter.</p>

<p> Power insertion and retrieval losses will be analyzed after the
measurements taken during the transmission are recorded. Attenuation,
field strength, and cavity Q will be calculated using the equations
presented in Dr. <ent type='ORG'>Corum</ent>'s papers. These papers are noted in the
references. If recorded results indicate power can be efficiently
coupled into or transmitted in the <ent type='PERSON'>Schumann</ent> Cavity, a second phase of
research involving power reception will be initiated.</p>

<p> Environmental Considerations</p>

<p> The extreme low frequencies (<ent type='ORG'>ELF</ent>), present in the environment have
several origins. The time varying magnetic fields produced as a result
of solar and lunar influences on ionospheric currents are on the order
of 30 nanoteslas. The largest time varying fields are those generated
by solar activity and thunderstorms. These magnetic fields reach a
maximum of 0.5 microteslas (uT) The magnetic fields produced as a
result of lightning discharges in the <ent type='PERSON'>Schumann</ent> Cavity peak at 7, 14, 20
and 26 Hz. The magnetic flux densities associated with these resonant
frequencies vary from 0.25 to 3.6 picoteslas. per root hertz
(pT/Hz1/2).</p>

<p> Exposure to man made sources of <ent type='ORG'>ELF</ent> can be up to 1 billion (1000
million or 1 x 109) times stronger than that of naturally occurring
fields. Household appliances operated at 60 Hz can produce fields as
high as 2.5 mT. The field under a 765 kV, 60 Hz power line carrying 1
amp per phase is 15 uT. <ent type='ORG'>ELF</ent> antennae systems that are used for
submarine communication produce fields of 20 uT. Video display
terminals produce fields of 2 uT, 1000000 times the strength of the
<ent type='PERSON'>Schumann</ent> Resonance frequencies.9</p>

<p> <ent type='ORG'>Project</ent> <ent type='ORG'>Tesla</ent> will use a 150 kw generator to excite the <ent type='PERSON'>Schumann</ent>
cavity. Calculations predict that the field strength due to this
excitation at 7.8 Hz will be on the order of 46 picoteslas.</p>

<p> Future Objectives</p>

<p> The successful resonating of the <ent type='PERSON'>Schumann</ent> Cavity and wireless
transmission of power on a small scale resulting in proof of principle
will require a second phase of engineering, the design of receiving
stations. On completion of the second phase, the third and fourth
phases of the project involving further tests and improvements and a
large scale demonstration project will be pursued to prove commercial
feasibility. Total cost from proof of principle to commercial
prototype is expected to total $3 million. Interest in participation
in this project may be directed to the author.</p>
