   @armagdn
   Many thanks for putting things in a way I could understand. That was the key to
make all the parts start to form together. I have had quite a time with the AC aspect
of coils and such. Something kept nagging at me and you finally led me to it.  Q
   I happen to have a copy of the 1959 ARRL and it has starting on page 56 a great
put it in plain text copy of what you are doing. Even does the harmonics. If I didn't
know better, I would say "LC Tank" and more than one.  And darn if it doesn't talk
of Q being the multiplier for the circulating power in the tank. A tank with 50ma at
100 Q is circulating 5amps in there! True the secondary would drag that down but...
Has to be heavy wire in there also to handle it, can we say lamp cord?
   This is just too much in the right direction to pass up trying. So I know where I
will be for a while. Get 11 days off from work thanksgiving holliday.   

   Now to find that freq calculator site that also gives the q of the circuit input.

"This is just too much in the right direction to pass up trying."



Here is a quote from a leading tesla expert speaking at an AERO conference.
"When you start using reflective kilowatts which is what were talking about here, it constitutes a new form of reactive power. And the reason why its so exciting is, because the same grid, that is in place today, carrying kilowatts, if it were carrying reactive power could service 1000 times more customers without increasing the size of the generating facility. Its just the nature of the beast. Its actually dictated by the terms of the maximum power transfer theorem. Which very clearly shows you , that you maxed uot on your transmission capabilities while the source impedance is equal to the conjugate of load impedance. So if you are doing that game resistively you’re immediately restricted by very severe limitations. But if you switch it to an impedance that is primarily reactive, and reduce resistance way down, which means your Q is going to go way up, then all of a sudden you are dealing with monstrous amount of power for the same input. This is the whole idea of Tesla’s concept, but nobody is using it. And its in every engineering book around, just gotta understand what it really means."

   And to think, I just read that in the '59 ARRL manual. I have to confess tho,
I was really dense on the aspect of AC. The more I study it, the more it shows
me. Not just 60hz but RF in general. Owe you a beer or two.

I got some questions. 

Firstly, has anyone repeated Tesla's Colorado Springs experiment where he powered an incandescent light bulb?  Is this what the Tesla experts are doing right now?  If so, where can I get this information?  I have looked and cannot find anything!  Just alot of bogus misconceptions on how his system is suppose to work - none of them are correct.  armagdn03, yours is the closest but I haven't fully read everything - don't have alot of time these days.


Secondly,

This is the whole idea of Tesla’s concept, but nobody is using it.

I am doing it! 

As of this Monday I was able to transmit about 30 Watts to power a 25 Watt incandescent light bulb through the ground plane - would be more efficient but I kept the ground plane separated from earth ground for safety reasons, so the transmitter had a slightly different frequency than the receiver.  If the ground plane is removed the light bulb turns off.  Its purely reactive power transfer.  Actually, you convert real power to reactive, send it down the ground plane as reactive, then transform it back to real power for usage.  So basically, I successfully reproduced Tesla's Colorado Springs experiment.  My next goal, for this Friday, is to test to see how well it works in an earth ground.  Then to eventually see how far I can take the receiver from the transmitter - this is not radio transmission either - its a weird reactive power ground wave which everyone seems to ignore.  My frequency is way too high (750kHz) for the earth though so I don't think I'll get very far. 

Again, I wanted to know if I'm the only one doing this since I can find no where on the internet where people have repeated this.  Tesla's work has been around for a while so I doubt I'm the first.  On these very forms people are using single wire transmission to power LEDs, but I haven't seen anyone take it to the higher scale.  The max my transmitter will send is 300 Watts but this is because of my power supply.  My input is only 3kV - I haven't taken it up to full power either because I'm scared of the repercussions - resonance of high Q coils is a scary thing.  But luckily I haven't made any large arcs, other than the noise from the spark gap (and the glow of the bulb) you wouldn't know its on.  I can 100% back Tesla's claims, his method works and is way better than the present mode of power transmission. 

Please, if you can give me more information as to what people have done that would help.  I am presenting my work at a conference in two weeks.  Would be nice to be the first, but I doubt it.

Thanks,
Charlie

One more thing:

True the secondary would drag that down but...

Actually, you can get around the damping effect the primary has on the secondary.  Its quite easy.  The secondary only acts as a regular transformer with high coupling to input energy into the system.  You use an "extra coil" as the main high Q resonator and keep it as far from the primary/secondary as possible.  Mine is only 4 feet away but I didn't want to make it any higher since the top of my transmitter is about 15 feet.  The wire length connecting the bottom of the extra coil does not factor in.  It seems these coils are quite impervious to what is applied to them on the bottom - the magic seems to happen at the top. 

In fact, this was rather confusing to me when I first read Tesla's colorado spring notes.  He never tells you that hes using the secondary as a regular transformer - I've heard it referred to as "the driver" setup.  But when you start doing the calculations of his secondary, it is not tuned to anything and has nothing to do with the extra coil.  He only uses it to input energy (and he never tells you, he just starts doing it out of no where).  He changes directions very rapidly in the notes and you can almost miss it.  Then if you look at his 1915 patent, the latest Tesla coil patent, you will notice that the bottom of the coil is actually a regular transformer, the primary wound tightly around a secondary.  The "Extra coil" is cleverly drawn above it but if you don't pay attention you would never notice that fact since the extra coil is drawn without separation between it and the secondary.  If you follow that patent you will not build the proper device to transmit energy.  The top toroid is way too large, the coils are too tightly wound, and the "extra coil" is too close to the secondary.  I'm almost positive Tesla did this on purpose because he didn't want to give away the secret of his transmission method.  Following that patent would only give you a device to generate large sparks - if that, nothing more.  Oddly enough, he writes his notes as if he knew someone would be reading them - someone other than him.  And because of that I feel he purposely left things out. 

I am still learning things, its an on going process, haha!
