Abstract

A wireless power transmission system comprising a transmitting inverted Tesla Coil or Magnifier connected to the ground by its high voltage terminal using a capacitive earth connection and transmitting power through the ground to a subsequent receiving Tesla Coil or Magnifier being well earthed through a capacitive earth connection or conventional earth with the distance between the two earth connections of the transmitter and receiver plus the length of the coils in the transmitter and receiver forming a tuned length and the system thus composed being operated at a frequency that is an harmonic or close to an harmonic of the tuned length thus established.

Claims

1-68. -68. (canceled)

69. An AC power transmission system comprising:

a transmitting coil connected to the ground using a capacitive earth connection buried in the ground located between the coil and the ground and transmitting power through the ground through the capacitive connection to a subsequent receiving coil which is well earthed through a capacitive earth connection buried in the ground or conventional earth connection with the distance between the two earth connections of the transmitter and receiver plus the length of the coils in the transmitter and receiver forming a tuned length and the system thus composed being operated at a frequency having a wavelength that is an harmonic or close to an harmonic of the tuned length thus established.

70. A system as claimed in claim 69 where the transmitting coil has a large capacitance on an elevated terminal and is used as the neutral side during power transmission.

71. A system as claimed in claim 69 where the transmitting coil is caused to impress voltage into the ground through buried capacitive earthing devices.

72. A system as claimed in claim 69 where the transmitting coil is brought into resonance with the second receiving coil to maximize the amount of energy available in the receiving coil.

73. A system as claimed in claim 72 where additional coils are added for transmission and reception of power by having each of them being located in a triangular grid pattern so that the transmitters and receivers that are within range of each other all use the same frequency or a harmonic of each other'"'"'s frequency augmenting the action of the other transmitters and receivers.

74. The system as claimed in claim 69, wherein the capacitor is formed from a first metal plate and at least a second metal plate.

75. The system of claim 74, wherein the first metal plate is formed as a substantially closed volume.

76. The system of claim 75, wherein the substantially closed volume is a sphere.

77. The system of claim 74 wherein the first metal plate is substantially enclosed by the second metal plate.

78. The system of claim 74 wherein the first and second plate is are located within the earth.

79. The system of claim 74 wherein the first plate is located at or near an earth/air interface.

80. The system of claim 69 wherein the capacitive earth connection is buried substantially in the earth.

81. The system of claim 69 wherein the capacitive earth connection is buried entirely in the earth.

82. A method of transmitting AC power through the earth between at least one first coil assembly and an at least one second coil assembly;

said method including forming a tuned network from said at least one first coil assembly and said at least one second coil assembly;

the method further comprising;

connecting a substantially capacitor between the at least one first coil assembly and earth;

connecting the at least one second coil assembly and earth;

such that a tuned path is formed through the earth between the at least one first coil assembly and the at least one second coil assembly when the at least one first coil assembly is excited at a predetermined frequency;

whereby AC power is transmitted through the capacitor and through the earth from the at least one first coil assembly to the at least one second coil assembly.

83. The method as claimed in claim 82 where the transmitting coil has a large capacitance on an elevated terminal and is used as the neutral side during power transmission.

84. The method as claimed in claim 82 where the transmitting coil is caused to impress voltage into the ground through buried capacitive earthing devices.

85. The method as claimed in claim 82 where the transmitting coil is brought into resonance with the second receiving Coil to maximize the amount of energy available in the receiving coil.

86. The method as claimed in claim 85 where additional coils are added for transmission and reception of power by having each of them being located in a triangular grid pattern so that the transmitters and receivers that are within range of each other all use the same frequency or a harmonic of each other'"'"'s frequency augmenting the action of the other transmitters and receivers.

87. The method of claim 82, wherein the buried capacitor is formed from a first metal plate and at least a second metal plate.

88. The method of claim 87, wherein the first metal plate is formed as a substantially closed volume.

89. The method of claim 88, wherein the substantially closed volume is a sphere.

90. The method of claim 87 wherein the first metal plate is substantially enclosed by the second metal plate.

91. The method of claim 87 wherein the first and second plate are located within the earth.
