Re: Tesla's Energy Transmission (Warning Long Post)
Hi Terry,
I think you amy misunderstand my idea - I will explain

The Springs system worked at "about" 40kW. "Similar" power distribution
ground systems "I" have worked with can "sink" (gulp) 250 Megawatts with
ground effects at 100 yards away being zilch. Yep, that's here in dry
sandy Colorado too... I think the "ground" can sink one "heck of a lot of
juice".
They ground systems you have worked with are, I presume, distributed ground
systems which imediately makes them less likely to create a resonant sytem
beacuse of the phase shift. They are also not tuned to the earth resonant
frequency which means they not only do not achieve resonance but probably
cancel out their own effects by destructive interference.
I was under the impression the Colorado springs system was about 125kVA?

100 MegaJoules???? If I remember right, he used about say 30kV at 60 Hz.
That would give a cap value of 1.85mF. Tesla's salt water caps fell far
short of that... The 1899 Colorado Springs power plant was not in the 100
megawatt class...
I'm working from the reported terminal voltage and the estimated terminal
capacitance - a 100pF capacitor at 10MV is 100MJ - the starting energy is not
to critical - it could be much less and the system would still work.

Where is "it written" that Tesla got a 120 foot spark, and where "on Earth
in 1899" did he find a Giga Joule????
The arcs went from the top of his transmitter to ground - the tower was about
120 feet tall.
The giga joule is the total energy stored in the resonant wave within the
earth - on each cycle more power is added to the wave until the power
dissipation in the earth is equal to the power input at which point the wave
energy remains constant.

One has to remember that the output "load" of a Tesla coil is basically the
local capacitance of the surrounding objects with loss. This represents a
very "local" effect. There is little that allows energy to travel outside
this local area of a Tesla coil even if it is a "big one" like Tesla used.
Tesla made one great "Tesla coil number uno". However, the world power
transmission thing seems to have fallen to pieces. Sounded good but it has
never been demonstrated, proven, worked, etc...
I am not talking about a local capacitive effect - the simple fact of
conduction - that if you shove a shedload of charge into a conductor it will
try and equalise throughout it - means that the charge waves from the
Colorado springs magnifier could propogate through the earth. The reason
nobody has repeated these observations is that the magnifier has to be
expressly designed to created these effects. It has to be tuned to the right
frequency and have a very, very large Ctop.
Sorry, but after 80+ years of playing with it, the results are still zero...
It is easy to "write and say" things like "1 Giga Joule" of energy (even in
Tesla's day). However, "Me thinks" I would notice it, if it was really
true ;-))) Even a Giga Joule is not that much power by today's standards
of power generation. Lasers and other "single shot" systems can easily
reach that "standard". However, no known Tesla coil system comes within
0.5% of it....
I'm not saying that the magnifier was pumping anything like 1GJ.
