.
Traditional Method Of Power Transmission
Need For Wireless System Of Energy Transmission
To minimize losses due to resistance of wire
To make the system more efficient about 90-94%
To eliminate inefficient & costly cables, towers & substations
To import & export electrical power internationally
Advanced Technology Of Transmission
Different Theories proposed are:
Transmission through or along the Earth
Propagation as a result of Terrestrial Resonance
Coupling to the Ionosphere using propagation through electrified gases
First theory given by:Fritz Lowenstein
Later two : Dr. Nikola Tesla
Coupling to the Ionosphere using propagation through electrified gases
Observation by Dr. Tesla:
Air under a partial evacuated vacuum can conduct high current better than Copper wires.
If transmitter is elevated to a level where air pressure is about 75 to 130mm & an excitation of Mega volts is applied, then the air will serve as a conductor for production of current.
The current can also be transmitted through air.
Propagation as a result of Terrestrial Resonance
SCHUMANN CAVITY RESONANCE
Earth behaves like an electric circuit & atmosphere acts like a weak conductor.
If there were no sources of charge, the existing electric charge would diffuse away in about 10 minutes.
There is a cavity defined by the surface of the Earth & the inner edge of the ionosphere 55 Kms up.At any moment the total charge residing in this cavity is 500,000Coulombs.
COLORADO EXPERIMENT
Schumann Resonance & Tesla Resonance
Practical Demonstration of Wireless Transmission
About the Plant:
Has a full size,51feet diameter,air core,RF resonating coil which is the largest part of the system.
130feet tower,insulated 30feet above ground.
Has a capacity of over 600 Kilowatts.
CONCLUSION
The successful resonating of the Schumann Cavity and wireless transmission of power on a small scale will require a second phase of engineering i.e.the design of receiving stations.
The third phase is further tests
The fourth phase is the improvements.
Total cost from proof of principle to commercial prototype is expected to total $3million.
