Method of Proposal of Wireless Power Transmission System

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    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  andŠ    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    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  thatŠ    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.      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.Š      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    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.Š    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    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,Š    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    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.
