Re: Tesla's Energy Transmission (Warning: Another Long Post)
Hi Mike,
nice to see I'm not alone :-) My comments:

I seem to remember reading that he used a 60kV Westinghouse transformer.
That would increase the energy by a factor of 4 from what state above in
that
respect alone. Also, didn't he use a rotary gap that would deliver a
firing
rate MUCH higher than 60Hz? This would allow the use of a smaller cap and
much more power throughput. I thought he used toothed wheels that allow for
break rates well over a thousand BPS.
I think the actual drive set up is irrelevant - the recorded terminal
voltages tell us all we need to know.

I thought the 120 foot sparks were indeed achieved once - just before he
blew
out the Colo. Spgs. power company's generators :o). I was under the
impression that the longitudinal "ground" waves were to be achieved by
operating down around 20kHz or less. I am also under the impression that
Tesla was attempting to excite a natural earth resonance(Schumman resonance
as they are now called) of about 7.8 Hz or perhaps a harmonic of such. All
of this was a result of his observation of lightning (see his paper "The
Problem of Increasing Human Energy").
Tesla was not attempting to excite the Schumman resonance as this is an
earth/ionosphere effect not a ground effect. The whole point of my theory is
that he was using charge waves, which are not subject to the inverse square
propogation law.

If I understand what I have read about all this, Tesla's longitudinal waves
would travel along the surface like the waves in a pond after a rock was
tossed into it and that with the proper frequency, the waves would
constructively interfere with each other after reaching the opposite point
of
the earth. Note that he never claimed to actually transmit current (which
would be incredibly lossy as Terry points out), but rather, he was intending
to create nodal points that one could then "pick off energy" by placing two
strategically place ground rods that would always be at different
potentials.
With the properly tuned receiver, one could utilize telluric currents and
it
would place no load on his generator. Incidentally, I also think that what
he said about getting usable amounts of energy could have been merely a
matter of perspective. In his days, there were no televisions or washing
machines or refrigerators(ok you get the idea). A usable amount of power
might have simply been enough for a couple of lightbulbs and a radio
receiver. A person in the middle of nowhere might appreciate that amount of
freely available power.
One other note about this is that in order to achieve this, Tesla
actually avoided the streamer discharge that we all try to maximize these
days. That is why his Wardenclyffe tower was designed with such a large
topload(I forget at the moment, but wasn't it about sixty something feet in
diameter?).
68
Another point is that his tower was over two hundred feet tall.
There would be no "local" objects to load down his tertiary coil, would
there? With such a large radius of curvature, tremendous voltages could be
achieved without the spark discharge and then the Q of the secondary would
be
very large. In this mode of operation, I believe the quarter wave theory is
valid rather than the lumped element notion that is valid with streamer
discharge. These are two entirely different modes of operation.
I agree on your point that the ¼ lamda operation does not apply under
streamer loaded conditions. The effects that this lack of streamer load had
on the behaviour of the resonant system are also obvious.

I seem to remember reading about a system that operated in Canada during
Tesla's lifetime, although is was not as large as the Wardenclyffe tower. I
also just recently read about some so called Scalar weapons and a "Tesla
Shield" developed by the Russians that are reported to work from Tesla's
principals. These were said to have been witnessed by pilots in Afganistan
who saw the effects from several miles away, so who knows how accurate this
is. I just mention it to stir up a little controversy :o)
I to have read of these huge russian tesla coils - although some of the stuff
eg. mind control, which they are creditted with seems a little far fetched.

It is also easy to dismiss Tesla's theories if you are trying to think about
them in regards to conventional EM theories, but unless someone actually
duplicates his work EXACTLY, how can it be proved that he was incorrect?
Perhaps it is due to my lack of electronic training(I learned most of what I
know on my own) that allows me to think that there could be more than meets
the eye in this area. I have read and reread as much of the available
material about Tesla in hopes of catching on to what he was really thinking,
which is difficult to do this since one has to filter through other's
opinions and ideas as to what Tesla himself was thinking. All I can really
say is that he insisted that his longitudinal waves were not like the
ordinary Hertzian waves and yet we still today try to equate the two.
My point is that they were not an EM phenomenon.

I won't give up my opinion on this at this point :o) I still think Tesla
had something there that nobody today quite understands as he did. I will
not change my mind until someone builds a coil system EXACTLY like Tesla's(
with a fifty foot plus diameter primary/secondary and the correspondingly
large tertiary coil and topload etc.), then pumps a few megawatts into the
system, and THEN shows that he was wrong.

I don't think that will be necessary - or possible.
