Abstract
Many researchers have speculated on the meaning of the phrase
"non-
Hertzian waves" as used by Dr. Nikola Tesla. Dr. Tesla 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 Heinrich Hertz
was using
and the system Dr. Tesla had designed, that Dr. Tesla was able
to
receive the endorsement of the renowned physicist, Lord Kelvin.1
To this day, however, there exists a confusion amongs researchers,
experimentalists, popular authors and laymen as to the meaning
of non-
Hertzian waves and the method Dr. Tesla 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 Tesla's 1899 Colorado
Springs experiments will be defined.
Early Theories of Electromagnetic Propagation
In pre-World War 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 Earth,
2. Propagation as a result of terrestrial resonances,
3. Coupling to the ionosphere using propagation through
electrified gases.
We shall concern our examination at this time to the latter
two
theories as they were both used by Dr. Tesla 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
Lowenstein, the first vice-president of the Institute of Radio
Page 1
Engineers, a man who had the enviable experience of assisting
Dr. Tesla
during the Colorado Springs experiments of 1899. Lowenstein presented
what came to be known as the "gliding wave" theory
of electromagnetic
radiation and propagation during a lecture before the IRE in
1915.
(Fig. 1)
Dr. Tesla delivered lectures to the Franklin Institute at
Philadelphia, in February, 1983, and to the National Electric
Light
Association in St. Louis, in March, 1983, concerning electromagnetic
wave propagation. The theory presented in those lectures proposed
that
the Earth could be considered as a conducting sphere and that
it could
support a large electrical charge. Dr. Tesla proposed to disturb
the
charge distribution on the surface of the Earth 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. Webster 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. Schumann and J.R. Waite.
The second method of energy propagation proposed by Dr. Tesla
was
that of the propagation of electrical energy through electrified
gases.
Dr. Tesla 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. Tesla 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;
"...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
(Fig. 2)
Resonating Planet Earth
Dr. James T. Corum and Kenneth L. Corum, in chapter two of
their soon
to be published book, A Tesla Primer, point out a number of statements
made by Dr. Tesla which indicate that he was using resonator
fields and
transmission line modes.
1. When he speaks of tuning his apparatus until Hertzian radiations
have been eliminated, he is referring to using ELF vibrations:
"...the
Hertzian effect has gradually been reduced through the lowering
of
frequency."3
2. "...the energy received does not diminish with the
square of the
distance, as it should, since the Hertzian radiation propagates
in a
hemisphere."3
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
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 Hertz waves represent energy which is radiated
and
Page 2
unrecoverable. The current energy, on the other hand, is preserved
and
can be recovered, theoretically at least, in its entirety."4
As Dr. Corum points out, "The last sentence seems to
indicate that
Tesla's Colorado Springs experiments could be properly interpreted
as
characteristic of a wave-guide probe in a cavity resonator."5
This was
in fact what led Dr. Tesla 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.
The Controversial Measurement;
It does not indicate faster than light velocity
The mathematical models and experimental data used by Schumann
and
Waite to describe ELF transmission and propagation are complex
and
beyond the scope of this paper. Dr. James F. Corum, Kenneth L.
Corum
and Dr. A-Hamid Aidinejad have, however, in a series of papers
presented at the 1984 Tesla Centennial Symposium and the 1986
International Tesla Symposium, applied the experimental values
obtained
by Dr. Tesla during his Colorado Springs experiments to the models
and
equations used by Schumann and Waite. The results of this exercise
have proved that the Earth and the surrounding atmosphere can
be used
as a cavity resonator for the wireless transmission of electrical
power. (Fig. 3)
Dr. Tesla 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
Corum and
Aidinejad point out, in their 1986 paper, "The Transient
Propagation of
ELF Pulses in the Earth Ionosphere Cavity", this measurement
represents
the coherence time of the Earth cavity resonator system. This
is also
known to students of radar systems as a determination of the
range
dependent parameter. The accompanying diagrams from Corum's and
Aidinejad's paper graphically illustrate the point. (Fig. 3 &
Fig. 4)
We now turn to a description of the methods to be used to
build, as
Dr. Tesla did in 1899, a cavity resonator for the wireless transmission
of electrical power.
PROJECT TESLA:
The Wireless Transmission of Electrical Energy Using Schumann
Resonance
It has been proven that electrical energy can be propagated
around
the world between the surface of the Earth and the ionosphere
at
extreme low frequencies in what is known as the Schumann Cavity.
The
Schumann cavity surrounds the Earth 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 Schumann Resonance frequency, propagate with
little
attenuation around the planet within the Schumann Cavity.
Page 3
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 Schumann Cavity to any point on Earth. This will result in
practical wireless transmission of electrical power.
Background
Although it was not until 1954-1959 when experimental measurements
were made of the frequency that is propagated in the resonant
cavity
surrounding the Earth, recent analysis shows that it was Nikola
Tesla
who, in 1899, first noticed the existence of stationary waves
in the
Schumann cavity. Tesla's experimental measurements of the wave
length
and frequency involved closely match Schumann's theoretical
calculations. Some of these observations were made in 1899 while
Tesla
was monitoring the electromagnetic radiations due to lightning
discharges in a thunderstorm which passed over his Colorado Springs
laboratory and then moved more than 200 miles eastward across
the
plains. In his Colorado Springs Notes, Tesla 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 Colorado Springs laboratory. The intent of the experiments
and the
laboratory Tesla had constructed was to prove that wireless
transmission of electrical power was possible.
Schumann Resonance is analogous to pushing a pendulum. The
intent of
Project Tesla is to create pulses or electrical disturbances
that would
travel in all directions around the Earth in the thin membrane
of non-
conductive air between the ground and the ionosphere. The pulses
or
waves would follow the surface of the Earth in all directions
expanding
outward to the maximum circumference of the Earth 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 Tesla was experimenting with
and
researching methods for "...power transmission and transmission
of
intelligible messages to any point on the globe." Although
Tesla 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.
The Need for a Wireless System of Energy Transmission
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
Page 4
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.
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.
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.
There are areas of the world where the need for electrical
power
exists, yet there is no method for delivering power. Africa 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 China, require the
electrical power necessary to bring them into the 20th century
and to
equal standing with western nations.
As first proposed by Buckminster Fuller, 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
the United States, this system would provide a saleable product
which
could do much to aid our balance of payments.
MARKET ANALYSIS
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 Project Tesla, the market for wireless power transmission
systems is enormous. It has the potential to become a multi-billion
dollar per year market.
Market Size
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.
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
Page 5
comparison, China generated only 17 million kilowatts and
India
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.
Market Projections
The Energy Information Agency (EIA), based in Washington,
D.C.,
reported the 1985 net generation of electric power to be 2,489
billion
kilowatt hours. At a conservative sale price of $.04 per kilowatt
hour
that results in a yearly income of 100 billion dollars. The EIA
also
reported that the 1985 capacity according to generator name plates
to
be 656,118 million watts. This would result in a yearly output
of
5,740 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 3,251 billion kilowatt hours).
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 1,625 billion
kilowatt hours were sold yearly at $.06/kilowatt, income would
total
9.7 billion dollars.
Project Tesla: Objectives
The objectives of Project Tesla are divided into three areas
of
investigation.
1. Demonstration that the Schumann 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.
Methods
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
11,000 feet. This system was originally built by Robert Golka
in 1973-
1974 and used until 1982 by the United States Air Force at Wendover
AFB
in Wendover, Utah. The USAF 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.
A location at a high altitude is initially advantageous for
reducing
atmospheric losses which work against an efficient coupling to
the
Schumann 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,
Page 6
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
Tesla 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 1,000 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
Schumann Cavity, and propagate around the entire Earth.
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 Schumann
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.
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.
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
Schumann 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.
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
Schumann
Cavity.
Evaluation Procedure
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.
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
Page 7
presented in Dr. Corum's papers. These papers are noted in
the
references. If recorded results indicate power can be efficiently
coupled into or transmitted in the Schumann Cavity, a second
phase of
research involving power reception will be initiated.
Environmental Considerations
The extreme low frequencies (ELF), 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 Schumann 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).
Exposure to man made sources of ELF 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. ELF antennae systems that are used for
submarine communication produce fields of 20 uT. Video display
terminals produce fields of 2 uT, 1,000,000 times the strength
of the
Schumann Resonance frequencies.9
Project Tesla will use a 150 kw generator to excite the Schumann
cavity. Calculations predict that the field strength due to this
excitation at 7.8 Hz will be on the order of 46 picoteslas.
Future Objectives
The successful resonating of the Schumann 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.
