Wardenclyffe - Tesla's true intention
I have been studying Tesla's work for a few years and I would like to present my findings here.
Tesla often used mechanical analogies to describe electrical apparatus. In fact a lot of his work after roughly 1900 is not described in direct terms. Let me start with a small walkthrough of his famous article 'THE PROBLEM OF INCREASING HUMAN ENERGY' written in June 1900: Quote:

The work referred to concerns using an intermediate product to condition the start product. When cooling air; it is first cooled a bit, then this cool air is used to cool incoming air so that in the next cooling step a lower temperature can be reached. By repeating this over and over, any temperature can be reached. Translated to electrical systems it could mean:

Tesla describes 3 of the 5 components that are required to generate energy from the ether. These 3 components are the key components:
1 – an oscillator that produces a constant frequency. It is well known how he used a spark gap and capacitor in combination with the primary coil to establish this. 2 – a high frequency transformer; a tuned primary and secondary coil. 3 – an extra coil, as he called it, in which through resonance any desired voltage can be achieved. Because the wire length in this coil is one quarter of the electrical wave length, one side of the coil shows a high current at 0 volts, the other end a high voltage at 0 current. This means that an excellent ground connection is essential. Now, why would Tesla not describe components 4 and 5? The 'dynamo of special design'. The answer is that he has already done so. Component 4 = component 3 and component 5 = component 2 but tuned at a different frequency. So the generating part has been fully described. However, if you try to reconstruct it, you will find that there is still one more problem to be solved: how do you connect the first 3 components to the last 2? If you read on in this article you will find that he starts talking about passing electricity through the air. In the pre-hearing interview of 1916 he describes this experiment but he uses 'sectional pipes' to represent a continuous medium. This does not make sense. In combination with this article it does make sense. Find the video on youtube where Eric Dollard demonstrates longitudinal electricity for Borderland Science at roughly 30 minutes you will see a set up that looks surprisingly much like Tesla's. Also not that Eric says he uses + because that seems to work best. There is appearantly a difference and so a connection of this type will have a rectifying effect. This turns the 'dynamo of special design' into a giant crystal receiver oscillating at a different frequency that the system that sets it into vibration. This means that you can get power from this receiving system without consequence for the first system. In other words: For Free. The article continues explaining how you can distribute electrical energy without wires all over the globe. But that part has been described pretty clearly by the master himself. Additional proof that this is the true system that Tesla designed for Wardenclyffe can be found in some documents that Leland Anderson copied from the Tesla Museum in Beograd. These circle the web under the name of 'rare notes'. I hope this will trigger new research and new studies of Tesla's writings. The only true master of electricity!

Ok. Here is what I think Tesla was trying to say : there is a lot of energy in radio waves but not in Hertz waves - those are rather like heliographic messages - not usable. We can catch those real radio waves and convert them into cold electricity which is normal electric current but on high frequency (this is famous "cold electricity"). Radio waves are hot but light, cold electricity is dense.
You can forget about electrons but Tesla was not against them (he knew they exist but as a wave packets in pure vacuum, else those are quantum stages or ether "density"). The most important article was about the heterodyning as a method how atoms catch radio waves. Transmit in order to receive. We are at the edge of the REAL radio age. I fully support explanation , seems the comprehension is just at the corner ! Universe is simple, we make complicated everything. Important: Look how easy everything coul be explained : 1.Ether is gaseous and all gases are a higher heat stage, must be cooled to condense into liquid 2. In gases only longitudinal waves are supported naturally but transverse are possible but highly impractical. Longitudinal are natural and are bases for two effects : pressure and sound. Two different effects like gravity and electromagnetism. This is the key to every force in nature. Prana and Akasha you see ?

@ GSM
I was reading Ernst's very interesting thread this morning. ![]() "This turns the 'dynamo of special design' into a giant crystal receiver oscillating at a different frequency that the system that sets it into vibration. This means that you can get power from this receiving system without consequence for the first system." This rang a lot of bells. @ Ernst Great thread! I would love to host the "rare notes" if you have them please. ![]()

Thanks for the responses so far!
@ GSM True! Tesla also mentioned that possibility but he did not support it because for the progress of human kind also inter-connection is essential. But today that has been taken care of by the internet.... Perhaps today he would also support the idea of many small generators. @ soundiceuk I have them as PDF, how can I forward them to you? ... Oh I just read that purelyconstructive has a link for you. Those are indeed the ones that I was refering to. One must keep in mind that the top-terminal of the free-system is not a metal sphere. It is a (almost) vacuum bulb. Remember Colorado Spring Notes where he 'suddenly' starts measuring the capacity of vacuum tubes? (If you don't I can look up the date for you) And the video of Eric Dollard...

There is probably someone here with more MOSFET experience than I have. Perhaps you can help me out.
Of course I am working on a proof of concept of the above system. But as every item has to be hand made this takes a while. Meanwhile, I thought to experiment a bit with the 'plasma bridge' and receiver coil. The biggest coil I have (84 cm diam, 72 cm height) has a SRF of about 160 KHz. So, to quickly have a rectified 160KHz high voltage source I was thinking about a TV/monitor fly-back transformer. I have a TC4421 MOSFET driver and a IPP60R380 MOSFET. I connect the driver directly to the MOSFET and I feed the driver directly with a TTL level signal. Using 5 V for the FBT everything holds pretty well, though the driver does get a bit warm. Using 12 V the driver gets a bit hot but the MOSFET (factory calls it 'cool mos' ![]() All voltages, currents and frequencies are well within specs. The only thing I can think of is that the driver is a bit too rough on the FET, pushing the dV/dt too high. Anyone? Suggestions?

Actually, there are 2 reasons why I started this thread:
1- to get your opinion about what I have found 2- to trigger more/new research in Tesla's writings As for the second reason, some extra info that may be of use: - always remember that his main focus was on electricity. When he writes about something outside of this field, this can mean 2 things: he is actually describing an electrical system or he has an electrical system in his mind which he may or may not have written about earlier and he has found an mechanical equivalent that he thinks may be usefull as well. In either case his mechanical system has an electrical equivalent. - he strongly believes in the existance of ether and opposes Einsteins ToR equally strongly. - electricity he describes mostly as a fluid, capacitor as a piston, coil as something that creates a vortex, induction as cohesion/adhesion etc. - his inventions always are highly practical. For this and other reasons you should have a look at patent 1113716, filed just before 1119732 which is commonly believed to be his magnifying transmitter. I can see no practical use and the esthetical value is questionable. I still do not understand what he has in mind here. - some of his later work include a speedometer and ship log. I strongly believe that he is refering to ways to extract energy from the movement of earth (=ship) through space (=ether=sea). A note on vortices (please read Prof.Dr-Ir. Konstantin Meyl's work): When you drain a bath tub, you will see a vortex in the water. You can distinquish 2 opposing forces here. One inward force, mainly present in the water. And one outward force; centrifugal force mainly present in the centre of the vortex (air). The reason why you see this vortex is the boundary between the inside (air) vortex and the outside (water) vortex. This kind of vortex is round in 2 dimensions. Now, if we could have a 4 dimensional vortex, that would be round in 3 dimensions (ball). It would be rotating and on its outside we would see a force towards its centre. Does someone see a similarity here with planets? ("now I understand how the cosmos works", Tesla said when he discovered his rotating magnetic fields) Meyl shows the relation between electricity and magnetism is also a vortex field. One is the outward force, the other the inward. This view is very helpful when trying to understand Tesla's work. (hope to see new threads on his work)

If in such configuration MOSFET is getting hot then there is no chance to make it work; also use big sink and cooler. I'm at the same stage, mostly everything ready but no experience with electronics makes it hard and I must be very careful to not damage any part. ![]()

Thank you all for the links.
Here is an interesting email I received this morning ![]() Hello all, I have replicated the power propagation via the ground. It is still the higher harmonics which will get through the ground to the receiver. Have a look at my latest video and please watch the previous videos to see the evolution to this stage for you to replicate. https://www.youtube.com/watch?v=Rj6rY7wgM0I

My first suggestion is to use plentiful decoupling capacitors very near to the supply pins of the TC4421 (1uF, 470nF, 47nF, all in directly parallel with the supply pins if you have not done so. I say this I suspect the nearfield of the coil(s) may induce unwanted voltages in the driver circuit. Also try place a 1 kOhm or so 'terminating' resistor directly across the input pin and the neg. supply pin of the TC4421 to prevent it becoming high impedance for any moment, to be able to pick-up any nearfield induction, this will not affect the TTL drive level at all. If these are of no help, then it may be about duty cycle, you wrote all the voltages and currents are within spec, the MOSFET dissipation simply exceeds the power level which could be allowed for free air cooling without using any amount of heat sink. At 12V supply voltage and at the same ON time for the MOSFET the self-dissipation is many times higher than at 5V, just consider the FBT's drain coil's DC + AC impedances: how much peak current can flow when the FET is ON, that current heats the FET. What you wrote on the driver's high speed switching and due to this the flyback pulse may approach or exceed in amplitude the limit of the MOSFET drain-source max voltage rating, well this could surely increase the FET's dissipation too. An oscilloscope test on the drain peak pulse voltage is in order of course. So maybe using a normal heat sink for the MOSFET is the solution, if the peak drain voltage is also ok, that is all, once you are satisfied with the currents and voltages. ? rgds, Gyula

Thank you, Gyula, for your suggestions!
I will surely implement all of them in the next attempt. Unfortunately the MOSFET that I was using is no more... ![]() But I think I still have 2 spares of this same type. Extra information: The duty cycle is pretty high, about 90% or so. This gives the best performance with an FBT. I did use a small heat sink, but that was obviously not enough. I use an old PC power supply (400W or there about). I tried with a 7 Ohm 60W resistor between the driver and the FET in order to limit this current a bit. That is when the FET went to FET-heaven. There is an extra diode (1KV/60A) across the drain-source to take care of the pulse that the FBT returns. Anyway, thanks again for your help! Ernst.

FET overheating
Hi Ernst,
All of gyula's suggestions are good ones. So be sure and follow them. Also you may not know what killed you FET when you added the 7 Ohm resistor. I will try to explain if you don't mind. When a transistor is turned fully on it is dissipating the least amount of power compared to being only partially turned on. When the transistor or FET is only partially turned on it is acting like a resistor so it will heat up a lot more than when it is turned fully on. As you reduced the gate voltage by putting the 7 Ohm resistor in the circuit you restricted the amount the FET could turn on and thus created even more heat in the FET. Mosfet driver chips help to overcome this problem by making sure the FET is either all the way on or all the way off so as to dissipate the least amount of power in the FET. We want our power to be dissipated in our load not our FET. Also you should be aware it is normal for power FETs to get pretty warm when running. Even with a heat sink they will feel pretty warm. They should not get hot enough to burn you though. Hope this helps. Quote:

Thanks for explaining, Carroll!
Yes, when you put it this way, it makes perfect sense. I have always been pretty succesfull, designing and building digital/computer circuits, but outside of the digital world, I fail where everyone else seems to succeed ![]() Imagine my surprise when my first 3-coil Tesla transformer worked (almost) straight away. ![]() The power supply for my new Tesla coil will be ready soon. Perhaps I should just stay with that. Thanks again! Ernst.

Can a ZVS be tuned to 160 KHz?
It's not just HF-HV. I need to be able to tune it's frequency to the SRF of the receiving coil.

If I got your question correctly you mean you use MOSFETs as switches to discharge capacitors, right? If yes, then you may wish to consider ALL the resistances and impedances that are included in the discharge circuit path. First thing is the capacitor itself you wish to discharge, see this link and in the Table you can see typical series resistance values for different electrolytic capacitor values and at different max working voltage ratings: Capacitance ESR typical values chart Suppose you have a capacitor of 220uF. 250V DC rated and you have charged it up to ,say, 200V DC voltage. From the Table in the link you can read 0.5 Ohm series resistance for a 250V rated 220uF capacitor. Now you discharge this with a decent srewdriver, that surely has some milliOhm maximum resistance which is negligible with respect to the inner resistance of the 0.5 Ohm. What current is involved when you short this capacitor? Simply apply Ohm's law and you get 200V/0.5 Ohm = 400 Amper peak current. And in case you happen to use a MOSFET switch that has an ON resistance under 1 Ohm (of course there are much lower values available) say you use a power FET with a 0.1 Ohm Drain-Source ON resistance, adding this to the 0.5 Ohm and using Ohm law again, you get 200V/0.6= 333.3 Amper. Of course I do not know your actual circuit total inner resistances and impedances to figure out the actual peak current which however must have surely exceeded your MOSFET max allowed drain-source current ratings. Even if you use 20-30 Amper drain current rated MOSFETs, you may easily exceed that limit and the device fails. So what you can do is study all the inner resistances and impedances of the components in advance which are in the path of the discharge current. Capacitors are very, very good voltage sources, due to their normally very low inner impedances, meaning huge current can flow out from them till the full discharge. Another issue can be the drain source voltage rating of the MOSFET because in case there is an inductance in the discharge path, the switch-off spike may exceed its rating. rgds, Gyula

Let me assume 1 Ohm for the cap inner ESR and let me assume a worst case 1 Ohm reactance for the 6uH and let me assume a 1 Ohm drain-source ON resistance for your MOSFET switch and let me assume 290V in the capacitor, the discharge current in the moment of the switch-on is 290/(1+1+1) = 96.6 Amper, this immediately starts reducing as the stored energy in the cap is reducing of course. Question is what is the drain-source current rating for your MOSFET, is it able to cope with the near 100A peak current and if yes, then for how long time (consult data sheet, it normally includes SOA, the maximum Safe Operational Area figure for pulsed conditions too). IF your 8uF is charged up for 430V, then the discharge current in the very first moment is 430/3=143.3A! Notice 1: my numbers above are assumptions of course but the 8uF capacitor's ESR is surely around 1 Ohm or lower, this could be known from the cap's data sheet if the type is a decent one, identifyable at all or could be measured by an ESR meter if available. Notice 2: unfortunately, for best power MOSFETs in the 500V or higher drain-source voltage rated ranges they have at least 45-50 milliOhm ON resistance at 30 Amper drain current. See this data sheet for instance: http://www.st.com/internet/com/TECHN...CD00002391.pdf or see these here: http://www.fairchildsemi.com/ds/FD/FDL100N50F.pdf and http://ixapps.ixys.com/DataSheet/DS1...00N50Q3%29.pdf (you can have them at Digikey). Notice 3: Consider the 8uF cap as a voltage source, this has the assumed 1 Ohm inner ESR resistance, then comes in series with the ESR the assumed 1 Ohm coil impedance, then in series comes the FET 1 Ohm ON resistance, these form a voltage divider whereby the capacitor voltage is divided to 3 parts between these resistances or impedances and you may wish to use a FET with a few milliOhm ON resistance only (not the 50 milliOhm type) so that the huge current should not cause big unwanted power loss (the power loss I*I*Rds across the switch surely cannot reach the 6uH coil at all, it is a waste). Hope this helps in some way. rgds, Gyula

Anyone interested in down scaling Wardenclyffe to something that could be used in our homes?
Let's first look at the full scale system. What would have happened in Wardenclyffe? - a 3 coil Tesla transformer creates a HF HV. The primairy and the shunt capacitor determine the main frequency. - the spark gap fires at a different frequency which causes an amplitude modulation on this main frequency. - the top load of this transformer (Tesla calls it 'the free system') consists of a vacuum bulb which has a small capacity resulting in very high voltages. - this gives longitudinal electrical waves that can easily be picked up by another vacuum bulb - this type of connection has a rectifying effect. Probably only a small effect but due to the very high voltages there will be a significant net result. - because of this rectifying effect the modulated (spark gap) frequency becomes visible and can be used to bring a secondary system into resonance - everything that happens in this secondary system has no consequence for the free system (because of the difference in frequency) so we can use this energy for free - this energy is used to set an electrical charge in motion which is coming from the earth, going to the top of the tower and back again. - this causes an electrical disturbance in the earths charge which can be picked up and used anywhere on earth Extra note: There are unconfirmed (?) rumours that Tesla used a large amount of UV lights in this tower. I was thinking that if those were in some way linked to the spark gap and if they would have an effect on the amount of electricity radiated from the vacuum bulb that might strongly increase the rectifying effect. Before we start down scaling, any comments on the full scale system as I have described it here? ![]() Ernst.

I would like to believe that the schematics in those notes are complete, but of course there is always a chance that while building this tower he thought up some further improvements. Eric Dollard showed in his video that vacuum tubes (lights) radiate longitudinal electricity when subjected to RF HV. I was wondering would this effect be stronger when irradiated with UV(C)? And what if those vacuum tubes contained tin? I would like to experiment with this a bit, but at this time I do not have the necessary equipment. Does anyone know about experiments in this area? For our garage-Wardenclyffe however this is not a necessity because today we can use HV diodes to accomplish the same. Yesterday I tested my magnetically quenched, pre-heated HF spark gap. Not as beautiful as some work that I have seen here, but it worked like a (bit violent ![]() Ernst.
