Tesla's Magnifying Transmitter "Replications"

[boguslaw]

I have stumbled upon that strange contradiction in Tesla words also. Once he said he is using high frequency then he stated frequency not higher then 35Khz or EM radiation occur.

After years of thinking I think I found astounding simple explanation of this contradiction, of course I'm only guessing.
Tesla never said about frequency in our current meaning of this word, except maybe when decribing Hertz radiation which is EM waves.
Tesla always work with speed of propagation of (longitudinal, sound-like) wave and with wavelength of it. He didn't need frequency, but he used this words as a the term for "repetition in time". So he produced very high frequency vibration (he was unable to measure actual frequency of it but he guessed it is much more then Mhz range) and the repetition of them or the train of vibration was his frequency of transmission wave.

You have to have a nice clean space between sounds of whistle or other instrument or you have dissonance when they overlap. This dissonance is radio or heat radiated in space. The other limitation is Earth system. Per analogy it is like ball filled with water and hydronic pump store energy in it (TMT). In receiver place pops a little bubble but it depends on elasticity of water surface. To fast pumping action and the wave forming bubble is too fast and elasticity cannot hold it back in regular oscillation mode and it breaks and spread water around.

Meyl probably just used a lower frequency to show a no output condition at
the receiver with a light at the transmitter on, then just go the resonant
frequency and the receiver light comes on, simple I can do it too.

You should build a setup and experiment with it.

People are free to think what they want, I think the higher the frequency the
more radiations there will be by default.

Maybe some day I will, but I don't have much money to spend and don't have much time to build either. I am now fully focussing on my moon-bounce project, because with the radio telescope in Dwingeloo we can use, we have an opportunity of a lifetime.

Anyway, I can't share any practical experience with you guys, but I can share my understanding of the fundamental concepts with you and I hope they are helpful.

In a way, you are right that with higher frequencies you get more radiation. All practical components have parasite components and the higher the frequencies, the more these parasite components stick their heads out of the sand, so the harder it becomes to control unwanted side effects from these parasite components. That is why RF engineering is so difficult.

So, when I say there is no fundamental frequency limit in using a wire as wave guide compared to using the earth as a waveguide, I say that in principle you can build a one-wire TMT system for any frequency you desire.

BUT that does not mean it is as easy to practically build one at 1 GHz as it is at 1 kHz. So, as a general rule you want to use the lowest practically possible frequencies. And since the most important factor for frequency dependency is the physical size of your system, you have some trade-offs to make.

Since your guiding wire needs to be a multiple of half a longitudinal wavelength, it is desirable to use high frequencies, because then you can do with shorter wires. The same thing goes for the top loads. The dimensions thereof get smaller the higher the frequency you use.

So, what I'm saying is that from the understanding of how your waves propagate, you can determine the optimal sizes of your load sphere/torus as well as the length of your guiding wire. The larger you can take these in practice, the easier it is to get everything function it in the way you intend it to, because the lower the frequencies you use, the less you have to worry about parasite components.

For example, a connecting wire of 23 cm length makes no practical difference when you are working at 1 kHz. It's just a connection at that frequency. But when you're working at the 23 cm radio amateur band around 1250 MHz you have yourself a nice radiating antenna with the same wire.

To sum this up: in theory, you can apply the TMT principle at any frequency you like, but at higher frequencies it becomes increasingly difficult to do so in practice and to prevent radiation in practice as well.

Can you give a reference of where Tesla states he uses High Frequency for
ground transmissions.

He clearly states in several documents the frequency must be lower then 35 Khz
or 20 Khz the different figures are a result of changing his opinion over time,
the patent says 20 thousand cycles per second. It means 20 thousand cycles
per second or 20 Khz. Why is that so difficult to accept ? Especially since it
makes sense. I have provided several references for Tesla stating the lower
frequencies namely less than 35 Khz.

References please.

Cheers

[dR-Green]

Well it's all relative isn't it. 20KHz is high frequency compared to 50Hz

I think boguslaw sort of has a point with the definition of frequency, but I also thought of this a few days ago and came to the conclusion that wouldn't make much difference. An "oscillation" would be a wave that goes positive and negative. "Frequency" could mean how often it peaks if you will. So whether it's positive or negative wouldn't make a difference. Except maybe now the "frequency" would be double that of the "oscillation rate", because for every wave you'd get two peaks.

3D model of TMT

Hi guys,

I just found a great 3D model of the TMT, with many interesting details, made with the open source tool Blender:

Free : Tesla Magnifying Transmitter, AKA Wardenclyffe Tower. A Technological Work of Art.


The Blender model can be downloaded here:

http://www.clipartillustration.com/freefiles/teslatower.zip

There's an accompanning video, which shows interesting details on the top load, but suggests there was no connection between the central shaft and the top load.


The artist said he based his model on the "Anderson drawing":

The *big* helper for me was a drawing I found called the Anderson_Drawing.gif. Search for that combined with terms such as “tesla” and the tower and such. I would upload it for you, but I do not want to breech any copyrights.

Also by searching in depth, you can find entire newspaper (largescale) graphics. They are highly-black/white contrast, but in studying those in comparison to other photographs, you can get a pretty good idea of how to assemble it. The Anderson Drawing will give you overall proportions, the photographs will help you with details. When you “get it right” everything falls together like a puzzle.

Some things in this model which I simply could not get right were:

1: The staircase.
2: The floor of the dome.
3: The actual device its built around.

There is also an underground apparatus to you can find online involving waterways and such. Trying to take those rough plans and making them an accurate model, though…very hard.

Somewhere out there, no doubt, there are accurate plans and photographs to be shared. Perhaps someone will get generous one day? As things become more open source and available in our day, Tesla’s original “share it for free” should perhaps motivate modern authorities on his work to share what they have.

Update: A very interesting article "rare notes" on the Tesla Tower:

http://www.capturedlightning.com/temp/Rare_Notes.pdf

Update 2: In one of these "rare notes" Tesla talks about a lambda/2 strip with a length of 93/200 miles. I calculated a frequency of about 300 kHz for such a wavelength...

You Guys always overload my IQ!

An "oscillation" would be a wave that goes positive and negative. "Frequency" could mean how often it peaks if you will

Wouldnt an oscillation be a wavelength and the frequency just a time factor?
If gamma rays are a shorter wavelength than a radio wave, then there are more gamma wavelengths than radio wavelengths in a certain time period or frequency. Would that be correct?

If gamma rays are a shorter wavelength than a radio wave, then there are more gamma wavelengths than radio wavelengths in a certain time period or frequency. Would that be correct?

An oscillation would have or express a certain wave length based on how fast its oscillating, this is like measuring the distance between each repeating + peak, or from the start of one whole wave/oscillation to the next (how much space is there between any two repeating points basically).

If you think of waves on water, the distance between each wave peak is the wave length.

"Frequency" would (could) be how frequently an event occurs, like how many peaks per second. With an oscillation that would be how many whole waves per second. So here the frequency, how frequently a peak event occurs, would be double that of the rate of oscillation. Because while the oscillation needs to go "0, +1, 0, -1", and that is "one cycle", you have got two peaks, so the "frequency" (of peaks) would be double.

If gamma rays are a shorter wavelength than a radio wave, then you can fit a lot more gamma ray peaks and troughs into the same amount of physical space. There would be a lot more oscillations in an equal amount of time/space. There can't be "more gamma wavelengths" because they are all the same length, another wavelength would no longer be called "gamma". "More wavelengths" would be like another radio station broadcasting - they can't use your wavelength otherwise you'll both be on the same radio station, they'd need to use a different wavelength therefore a different frequency, and then they can coexist.

"More wavelengths" in this context I think is the same as saying "wave band", like you could call "light" and "sound" particular "wave bands", because all colours and pitch of sounds are different wavelengths to each other, but they fall into the same "wave band" that we have named accordingly

Thinking about this submarine project has led me to think an interesting thought... Coil capacitance.

A capacitor inside the sub is not much use, because once it has been drained then it needs to charge back up again. It works like a fast charging and discharging battery in this respect, so of no practical use in terms of improving performance. That is, it affects things in the dimension of time, but nothing else.

But what if there was a bigger capacitor - one that can deliver the energy to the load, rather than storing it as a part of the load. What if there was a big capacitor outside the tub of water, so when there is a load demand there's some energy already available externally that can be delivered.

What if the coil itself acted as the capacitor. I'm pretty sure this sort of effect is already happening to a certain degree, but what if there's a lot more to it than that. If the coil could temporarily store (more) energy, then when the sub draws power it wouldn't only be drawing power directly, like an instant "push-pull" effect between input and output, but rather there's this "elastic band" type of effect due to the capacitance. And so you'd get a constant supply of power "out of the coil" due to it acting like a large external capacitor rather than just depleting what little energy can be stored in a smaller low capacitance coil.

I haven't explained that properly because I don't want to write an essay at the moment and I haven't really thought it through yet, but the image of it in my head certainly makes sense

[edit] If the rate of vibration of the load is infinitely higher than that of the coil/supplying circuit, or let's say 100 times so I can write about it, if the load "sucks" energy out 100 times faster than the supplying circuit is supplying it, then capacitor or no capacitor in the load, it's using more faster than what's coming in. For every charge/discharge cycle of the coil, the load is trying to take it out 100 times faster, so the capacitor in your load is going to be useless. But if the coil can store more energy, then this wouldn't be such a problem?

[boguslaw]

I have explained it and I'm sure it will work. Normal capacitor is a break in circuit. With proper connecting of coil itself via load or parallel to load we should be able to join coil inductance and capacitance in the self-feeding system without break. The only problem is to find resonant frequency. It has to match RLC resonance and support magnetically coil part of circuit (for example being 1/4 of wavelength of applied vibration). I'm 100% sure with strict setting it will work ! Distributed capacitance is however very hard to measure.

Where did you explain it?

Anyway I've just been doing the first test of the "extra coil". Results are very good so far I had to change from 28.8g 13 metres of 24 SWG wire to 28.6g 8.25 metres 22 SWG because the 24 SWG wouldn't fit. (So now I also have 2 matching lengths of wire to make more secondaries for the small coils). But the output is better than before, also using 50pF more capacitance. Same spacing between the turns on the extra coil as there is in the spiral coil. Obviously the "resonant length" or whatever hasn't been taken into consideration here because I did it by weight. Originally the 24 SWG would have been the same length as the spiral primary but since it didn't fit on the frame, there's now about 8.25m of thicker wire. I'm pleased with the results so far anyway. I'll post all the details and measurements soon. My initial thought, also since I tried about 21m of 26 SWG once before, is that the extra coil should not be longer than the secondary. Shorter seems to be ok, but longer did not yield good results. But that coil wasn't a "real" test so I can't be sure about that at the moment.

[dR-Green]

Hi all. I've uploaded a video of a test of the coil here. I included the normal setup at the start to be able to compare.

Tesla Flat Spiral Coil And "Extra Coil" Test-01 - YouTube

Also I just found it possible to light an incandescent bulb without wires connecting to the coil. Transmitting into the pot of soil, connecting the bulb to the other copper pipe lights the bulb (with suitable "load" on the other side of the bulb IE a piece of metal). I can also place a jar of water on the soil, and connect the bulb to the lid and it lights up. The wire coming out of the bulb is completely safe to handle with the jar method, no sparks of any kind, and it even lights a fluorescent.

Very interesting stuff

nice

ok question...

did you move your hand into the bulb and see if you could "feel" a pressure build or push back if you will against your hand?

Eric says in virtually every video that you can feel the pressure from the hot cathode being transmitted.

Not really, I can feel heat. It gets hard to tell if I'm imagining things or if it's cool in one direction and hot in another. [edit] I'm not using vacuum bulbs either.

But I can most definitely confirm that it attracts a piece of aluminium tape

Suspending the tape from a point anywhere but directly above the globe it is theorised to be attracted to would exclude gravity as the cause.
