Tesla's Magnifying Transmitter "Replications"

[MonsieurM]

Farmhand, thank you for the Tesla link ...you always provide some awesome links

congrats on the baby goats

One species, the inland taipan (Oxyuranus microlepidotus), which is endemic to Australia, has the most toxic venom of any terrestrial snake species worldwide.

damn , you live dangerously...

ps: Farmhand, when you look at the drawings in the book you see copper coils, I see a copper made emf....

[dR-Green]

Thanks for the help Farmhand Congrats on the goats Interesting analogy hehe. The funny thing is it makes sense, it's a fact of nature. But then there's division and multiplication at the same time, both interacting to produce the end result of what looks like you have more than you started with in our "medium scale" world. But a cell divides itself, it doesn't "multiply".

Do you have a HV diode on the output of the ignition coil ? The diode is important. If you use two ignition coils they'll both need diode's on the HV output.

No I don't. I put together 13 1N4007 in series after you mentioned it, but the results were not good. I have 40 UF5408 on the way which are faster so I'll see what those are like when they come.

Thanks for the diagram. I've assumed that the negative side of the primary and secondary of the ignition coil are tied together, so I connect the negative of the ignition coil to earth. Maybe this is affecting things come to think of it because from the SEC experiments I've learned that above the transistor is basically the "positive" side of the circuit, and it didn't like to be earthed, the output was smaller. I get no output at all if I don't connect the negative of the ignition coil to earth though (probably relates back to the having problems using capacitors on the secondary, in that it wouldn't do anything except make a noise).

I also have my spark gap on the "positive" side, opposite to yours in the diagram, maybe this has something to do with poor output with the diodes?

I started off with 680pF capacitance, tried 2 in parallel for 1360pF, and then tried them in series. Results got better with them in series, so I added another 500pF in series, I dunno if that made it better or worse, but I've left it there for now anyway. That's all the caps I can use on the transmitter side because I only have the same amount again to go on the receiver. But I think you're right, it looks like smaller capacitance is better. There was a significant difference between 680pf and 2 in series for 340pF. I need to compare again with the other 500pF in series to see the difference.

From the video you posted it sounds like the spark gap is sparking at the same frequency at 1:00 as it is at 1:07. But at 1:00 there are more harmonics to the sound. 1:07 is a cleaner single tone if you will.

I'll post a couple of videos shortly. I forgot to film a couple of the things I wanted to show so I'll have to make another video now. But I tested the receiver for the first time with the ignition coils last night and came up with this:

Tesla Flat Spiral Coils Transmitter And Receiver One Wire/"Wireless" Power Transmission - YouTube

12v 21 LED array on the output. The CFL connected on the inside of the receiver seems to make it easier to tune the spark gap and in fact the output gets better, so I left it there for making the demo. The meter is showing about 400mA input, transmitter and receiver connected with 250g spool of 20 SWG wire between them.

First successful test that yields ANY output from the receiver since I made the coils

[Farmhand]

Hi dR, Power out, good stuff. If you added more terminal capacitance you might need more primary capacitance. But you will work it out for sure. I used a microwave oven diode, which is rated to only 4000 v I think. From what I can guess the spark gap will determin the voltage through the diode. Big gap more voltage.

I went with the spark gap on the negative side of the coil because thats what I'm used to doing with mosfets, and that's how Don Smith shows it with the NST and diode's with spark gap. One way the coil is tied to negative then pulsed the other way the coil is tied to positive but it's open ended anyway so I'm not sure it make's a difference I tried it on the positive and it seemed the same to me.

Some of those "near objects" might affect the coils, which is kind of an advantage to the helical design because less bench area is needed and the termination can be up away from the "near objects" a bit more. It seems to affect the transmitter more than the receiver for me. It's difficult for me to make the benchspace to keep clear around the bottom. It almost seems I am limited by the interaction between the terminal field and the bench/ objects sucking power directly from the toroid terminal field.

I quoted this from the other thread. I think the bolded part will happen no matter what and Tesla outlined the uses for the Electromagnetic field created. Which for all intents and purposes cannot be avoided. Creating a field around the terminal does not ensure huge losses I don't think. But things in the field can steal energy or use it if they can. Not sure how it would be possible to charge an open capacitor with 1000's of volts without creating some kind of field around it.

WORLD SYSTEM OF WIRELESS TRANSMISSION OF ENERGY
by Nikola Tesla

One of the most important uses of wireless energy will be undoubtedly for the propulsion of flying machines to which power can be readily supplied without ground connection, for although the flow of the currents is confined to the earth an electro magnetic field is created in the atmosphere surrounding it. If conductors or circuits accurately attuned and properly positioned are carried by the plane, energy is drawn into these circuits much the same as a fluid will pass through a hole created in the container. With an industrial plant of great capacity sufficient power can be derived in this manner to propel any kind of aerial machine. This I have always considered as the best and permanent solution of the problems of flight. No fuel of any kind will be required as the propulsion will be accomplished by light electric motors operated at great speed.

You may be right below here too. Harmonics are good though apparently. For us.

From the video you posted it sounds like the spark gap is sparking at the same frequency at 1:00 as it is at 1:07. But at 1:00 there are more harmonics to the sound. 1:07 is a cleaner single tone if you will.

Yeah I know the animals are not OU but they gather in energy from the environment and make it availiable for me to use for free. But not when they are joined together. It all a numbers game really. I was just joking for an excuse to show my baby goats. Though one of them has weak back legs so it may not survive. It's getting stronger but still weak. Like counting my chickens before they hatch. Them's the breaks.

Cheers

Ok, the videos are done. In this one I've put the circuit diagrams of the thing I'm testing. It starts with a conventional closed loop, then I use earth instead of the inside of the spiral coil secondary. The filament also lights when the "current" has to pass through the fluorescent tube, or a chamber of gas, in series. I'm assuming that's not "supposed" to happen

Tesla Longitudinal Electricity Open Loop Circuits Experiment - YouTube

And here I don't even use earth. The other end of the incandescent is first connected to an open ended coil of wire and then a fluorescent tube.

Tesla Longitudinal Electricity One Wire Filament Bulb Test - YouTube

Very low power obviously, but I think this pretty much proves that the principle works

Some of those "near objects" might affect the coils, which is kind of an advantage to the helical design because less bench area is needed and the termination can be up away from the "near objects" a bit more. It seems to affect the transmitter more than the receiver for me. It's difficult for me to make the benchspace to keep clear around the bottom. It almost seems I am limited by the interaction between the terminal field and the bench/ objects sucking power directly from the toroid terminal field.

I quoted this from the other thread. I think the bolded part will happen no matter what and Tesla outlined the uses for the Electromagnetic field created. Which for all intents and purposes cannot be avoided. Creating a field around the terminal does not ensure huge losses I don't think. But things in the field can steal energy or use it if they can. Not sure how it would be possible to charge an open capacitor with 1000's of volts without creating some kind of field around it.

Yes the setting isn't ideal I agree, but it's the best I can do for now. I'm not too happy with my ignition coil/555 power supply setup yet either so I'm not too concerned with objects affecting things for the moment. Most of them are pretty much static and don't move around so whatever effect it had before should remain the same the next time (And hopefully not give me different results each time).

I've been wondering about how the planes and cars and what not were supposed to have energy delivered if the earth was the one wire connection. Things stealing the energy makes sense. What are you referring to with the open capacitor? The only thing I've seen of that sort is Eric Dollard charging a capacitor from light or radiant energy being emitted from an incandescent vacuum bulb.

I hope the little goat gets stronger btw

[Farmhand]

Good job dR, I like the progress you're making, I'll make comments as I watch the video's then I won't get mixed up or forget to ask the questions I want to ask.

First off what type of ground are you using ? Looks like the ground works Ok,
I can't see a problem with connecting the Earth like that, should be OK, but if you do try the spark gap on the negative of the coil make the earth circuit-side I think.

The filament definately lights up better the second way but the light is a bit purple indicating some plasma so quite high voltage which is evident when it will still light the filament through the fluro - gas tube. You can transmitt through a plasma tube if you're voltage is high enough I guess, Eric shows that I think. And the fluro is lighting up good too. I notice the filament lights better with the cfl on the termination than the neon, so that means something. Remember with the cfl on the termination there is energy being radiated in the form of light, which is ok if thats what you want, I do it too, for the light . I do understand you're trying stuff out, I think with ball terminations it'll be spectacular.

Looks like you did very well with the matching of the wire in the primary secondary. It will work very well when you sort out the 555 and stuff the way you want it. I see no reason why that won't transmitt energy to the other coil very well. Enyo Cool.

I'm not surprised to see it work into a coil rather than the ground, I think as long as there is something to work into as a ground and a small capacitance on the inner terminal as a termination you'll get results.

I think that setup will work very well to transmitt energy from one coil to the other with a termination on the inner end of each coil and both outer ends joined by a ground connection be it a wire with an added resistance or otherwise as the ground connection between the two, and taking from the "C" coil (output coil) of the receiver but, using a spark gap you will then have spark gap voltage AC at the receiver output coil to deal with.

Good job. things are lighting up all which ways so thats good.

To answer you're question about the open capacitor, the Termination on the inner end of the secondary is the open capacitor, if you noticed there are some who would say there should be no field or anything at the Termination (terminal capacitance), but of course there will be. There will also be some losses there, the amount depending on the size, shape and quality of the terminal sphere or toroid and the voltage used in relation to those things.

For eg, if I use a very small ball the energy will leak at only a low voltage as compared to a big one but if the ball is too big and has too much capacitance the voltage will be lower for the same amount of energy, as will the frequency, and power density I think is related to frequency. Higher frequency means the same size system can deliver more power in the same time frame.. The higher the voltage the bigger the field around the termination (terminal) so more chance of energy being intercepted or lost or stolen. But conversely the bigger the field the easier it is to tap and use. It's not Sacrilege to use the field as some would say, it's very usefull. But for transmissions we would want the termination or terminal to be optimum. Which depends on the system I guess.

Cheers

P.S. I'm fairly certain, and my experiments tell me that if we try to transmitt energy through the ground to a distance using too high of a frequency the losses will be huge and negate any advantage to the higher frequency or even not work at all much. So still it is my belief that to successfully transmitt over a distance through the actual Earth without wire's, lower frequencies requiring fairly large coils will be needed. And a harmonic of the Earths frequency is desireable. I think. As suggested by lamare.

A system transmitting power using 21 000 Hz can deliver 350 times more energy than the same size system using 60 Hz. And with no wire's to pay for we can see how this would save us all an enormous amount of money and resources if it worked well and replaced the exsisting system.

Warning Small rant :
But do our governments want to save money and resources. No because to save money for us means less taxes because we would need less money. It would also stiffle economic growth which governments don't want. But economies cannot grow forever. Thats why they collapse them so they can grow again. It's all so wastefull and serves only the rich. If the outcome of implementing the system does not suit them they will not even entertain the idea of investigating or testing it. Which is wrong. I don't hear of any real testing of these systems. And I don't understand why. Except that it is not allowed or wanted, not that it doesn't work.

End rant.

[Farmhand]

Oh and speaking of the field, it occurs to me if there is a field extending out 1 meter from my toroid terminal the toroid terminal should be at least more than 1 meter from the ground or other grounded objects even non or poorly conductive ones. If not the ground or objects which the field reaches would probably drain energy directly from the field. I noticed when i raised my toroid terminal up a few inches the possible voltage of the terminal rose which I could see by the scope. which of course would make the field bigger, I guess.

The thing is that the terminal being one side of the open capacitor and the earth the other the distance between the two will affect the capacitance of the terminal (closer to the ground = more capacitance but less voltage to beakdown or leak) the terminal capacitance will change most because it won't affect the ground (Earth) much, and if it were right next to the ground like 6 inch's this would not be good. I think some way of adjusting the Termination height will be very usefull.

All very complicated I know but after some experimentation it get's easier to manipulate. And things reveal themselves in patterns. I can't give specifices in numbers. But I think others could. If given the input data. And my definitions are likely off.

Cheers

[Farmhand]

This is what I don't understand.

We use the one wire Earth return system of electrical transmission.
Basically this setup, Nikola's way. This is the patent for the tranformer. He patented this transformer in 1897. Over 100 years ago.
I think the single wire Earth return method was discovered earlier by someone else.

However.

We didn't go to what Nikola says is a better system. Wireless. Earth transmission. Patented year 1900.

Or even to what Nikola said is the best system he invented, the pinnicle of power and signal transmission. Patented 1914 during The Great War. WW1

I can see that it would indeed need to be a world system, as if one were built in one country and tuned to the vibrations of the Earth then people in other countries could tune into that too with a receiver, as it would be availiable world wide. I don't see how it could be prevented.

However this will always be it's blessing or it's downfall. Unfortunately. No one wants to generate all the power when anybody can tap it anywhere in the world and use it. Energy still needs to be put in the system for it to work. It would never be free totally. Tesla states that the power of a waterfall could be made availiable anywhere on the planet. This does not mean it is a system for harvesting free energy but because of it's vibration in harmony with the planet it would receive and tap some vibrational energy from the globe, reinforcing resonance. But it would need to be tuned for this.

Having said all that, the basic system for our power transmission is very old and must be outdated by now surely.

Cheers

[dR-Green]

Hi all. I just made an interesting discovery Upon Farmhand's suggestion I replaced the CFL with the two toilet cistern floats that I've covered with aluminium tape and used them as terminals. Results on the desk were slightly better, but just as difficult to tune, or keep a constant brightness to the LEDs on the receiver output. So, since someone mentioned it earlier in this thread, I thought I'd increase the distance slightly. Nothing much, just as far as the wires will reach and whatever space there is left on my bed. I've moved them from about 40cm apart to 220cm distance. I was extremely pleased to find that the LEDs were a lot brighter, and they were producing a constant light. I'm so excited I had to post about it lol I'll reply to your points shortly Farmhand

[Farmhand]

Excelent, Considering the relatively small amount of power you're using you have good results already. One thing i came to realise is that this type of setup and method with resonant coils is very usefull especially for light. So decided I would just plod along and try not to miss anything that might be important. I hope to learn some of the math and stuff sooner or later. I don't think it's wise for me to rely on online calculators for ever.

Since I am not good with numbers I like to see results and file it all in my head. When I get something good happening I try to maximise it but watch for the side effects. And use time to observe the setup over long time periods. Nothing much changes with time except the source battery voltage go's down. Unfortunately.

One problem with batteries as a source is the changing voltage, it's not so bad for resonance but it does have a small effect on the voltage out. One thing I worked out to keep the voltage down usefully is to use a cap pulser to float a battery from the receiver, it can charge a 7 aH in reasonable time but struggles to raise the voltage of a car battery thats drained but it will float charged ones at over 14 volts or whatever I set the pulser power to below that. This keeps the output loaded a bit so the LED's don't get too much voltage, I think 50 volts is too much for 6 x 5 mm LED's and a 1 K resistor.

I've got 65 ohms resistance between the coils now and about 3.5 meters. I ordered 100 meters of coax. to try for 100 meters transmission, but I want to improve my Toroid terminals first. I'm going to order some of those LED lights like you have too if I can because I want a few different lights to try.
Hopefully if I use a voltage doubler on the input I will be able to light Fluro Tubes from the receiver with wires.

Trying to get those core doco's to watch but I had trouble with my connection, i'll get them tonight.

I also need to setup a Plate 'P' radiant energy collector far enough from the coils to only get a bit of energy so I can try to work out the best way to use them, with Tesla coil nearby at least it is garanteed to work so I have somewhere to work from to improve how I do it and I can work inside. People are interested in the radiant energy collectors, me especially so I should try a few things like coated plate and uncoated plate, cap sizes.

Cheers

[Farmhand]

Hi all, I thought I would share this now incase anyone was considering making Toroid terminals for Tesla coils. I finally made it to the pool store and bought what they call "pool pole's" they only cost about $4.00 each and are flexable but hold thier cross section circular shape fairly well when bent quite tightly, these one's are 65 mm diameter and each one is 1.5 meters long so a fairly big toroid could be made with one or a few small ones. The ends should glue together OK with some kind of adhesive. I think from one of these, some conductive tape and some aluminium discs a reasonable toroid terminal will form.

My only concern is the slightly rough surface which shouldn't be a problem as long as the conductive tape tape sticks.

My baby goat made a good recovery, his leg was bending both ways at the ankle, I bandaged it up so it was bent the correct way and a few days later it seems normal. Must of gotten dislocated or something.

Here at 1:10 mins you can see his left leg bending the wrong way.

Meaning of Magnify

Hi all, I've been lurking through some other forums, and I have come to the conclusion that there are a lot of people who seem to think that to magnify something, that something is somehow actually made bigger when of course this is not the case.

Magnification - Wikipedia, the free encyclopedia

Does a magnifying glass actually make an ant bigger when you look at it ? The answer of course is. No.

Now you may ask how can Tesla make the claim he does in the passage below.



Uploaded with ImageShack.us

The answer is simple. Time. Tesla increased the voltage of the terminals by charging them to high potential "before" begining full power transmission. However the amount of energy taken from the receiver would need to remain less than the amount of energy input to the transmitter once the transmission begins, or the voltage at the top terminals would drop. Halting the magnification. The energy is magnified not increased there is a difference. The magnifying glass focuses the energy to increase it's effectiveness. Light. It does not somehow gather light that does not enter the magnifying lens. Also note he says "Low frequency". That is important.

And I am also almost certain that Tesla did not use a spark gap in his magnifying transmitter. So the magnification he speaks of had "nothing" to do with a spark gap. Read below the blow replaced the arc.


Uploaded with ImageShack.us


The current through the primary coil is magnified in his primary circuit by the use of charging inductors and capacitors. The field collapse of the inductors is stored in the primary capacitor for the next cycle and added to the current from the source during the next cycle. Thus magnifying the current and increasing it's effectiveness.

Here it is explained. Test from here. Page 11 Nikola Tesla on his work with ... - Google Books


Uploaded with ImageShack.us

He uses the words magnify, magnification and magnifying all in the one paragraph and he is talking about the effect of the primary capacitor.

So why the mystery I wonder.

So I hope this helps people to understand that to magnify something does not actually increase that something, although some people do use the words wrongly in my opinion to try to make it seem like majic. There is no majic. And no energy is created from nothing, ever. Most of us know this to be true of course.

There is the possibility of the reinforcing of resonance by the Earths vibration of course. But I for one will not say it is fact unless I can prove it. I am usually carefull to add the words "I think" when I say things, but sometimes I forget. However very few things can be said to be undeniable fact. In my opinion we all only have opinions. We only observe, we do not make things be by saying it is so. Energy from outside any system can be harnessed into a system, but this is not important to the principal of how The Magnifying Transmitter works, it is just a bonus if tuned for and realised.

Please if people are actually interested they should do thier own research and do not skim. Read it till you understand. Then go back later and read again you may understand better. I did.

All the text capture's are from Nikola Tesla on his work with alternating currents.

Nikola Tesla on his work with ... - Google Books

Oh and the energy is transmitted through the ground not the air. As described in the passage below. If done Tesla's way. But if you build a magnifying transmitter and own it you can use it any way you wish too. Even to make big sparks. How it is used does not change what it is. ie. A rifle can be used for a club, but it is still a rifle.

Cheers all.

P.S. Soon i will give my opinion on a possible role lightning could play. And propose a possible experiment to test it in a rudimentary way. I'll make drawings (sketches).

[dR-Green]

And four days later he's the one on the left in this picture. Left leg seems to be working ok now. Fixed him up.

Excellent news I couldn't see the video though. I took a little longer to get back than I expected sorry, so I'll reply to the earlier one first, and there's other things I've found since which I'd like to add in between, so we'll see how this goes

First off what type of ground are you using ?

I have it plugged in to the nearest mains socket for the moment.

To add to that, which might make more sense after I've explained the whole thing, I don't think that a 1K resistor on the output accurately simulates the earth

I thought it would be pretty cool to be able to go downstairs and plug into another mains socket and use that as the one wire/earth connection, but no such luck. I can get it to work off the same 4 to 1 adapter, but it won't do it from the socket across the room.

It's not so much a matter of the earth absorbing the energy or whatever, because I can earth the transmitter secondary and still get an output, but it depends where I connect the receiver. If it's directly to the same earth connection then the receiver works. If I have a fluorescent between the coils then the earth just absorbs all the energy and the receiver doesn't work. So I don't think a 1K resistor between the coils is quite a fair test in terms of its intended purpose. Transmitting through the earth seems to be much more difficult. Not that I've tried that test exactly, just that it seems that the earth is more easily absorbing all the energy so I expect getting an output to be much harder than connecting a 1K resistor.

The filament definately lights up better the second way but the light is a bit purple indicating some plasma so quite high voltage which is evident when it will still light the filament through the fluro - gas tube. You can transmitt through a plasma tube if you're voltage is high enough I guess, Eric shows that I think. And the fluro is lighting up good too.

There's no plasma I'm afraid That's just my 10+ year old webcam which isn't amazing quality in the best of conditions, it doesn't like dark at all. I'll try and get better pictures of it that does a better job of showing the real colour/brightness.

The most interesting thing I thought, and why I keep doing it in the videos but haven't explained, is that the brightness of the filament doesn't change when I add the fluorescent. Given the circumstances, that the bulb isn't even connected in a closed loop, I'd expect lighting a fluorescent from a connection before the bulb would certainly make the bulb dimmer if not go off altogether. But it doesn't affect it at all.

but, using a spark gap you will then have spark gap voltage AC at the receiver output coil to deal with.

I don't really know what's going on there. I agree there should be what you say, but at the moment there's certainly no spark gap voltage there. I can get small sparks when I short it, but nothing spark gappish.

To answer you're question about the open capacitor, the Termination on the inner end of the secondary is the open capacitor, if you noticed there are some who would say there should be no field or anything at the Termination (terminal capacitance), but of course there will be. There will also be some losses there, the amount depending on the size, shape and quality of the terminal sphere or toroid and the voltage used in relation to those things.

Ah, thanks

I'm fairly certain, and my experiments tell me that if we try to transmitt energy through the ground to a distance using too high of a frequency the losses will be huge and negate any advantage to the higher frequency or even not work at all much. So still it is my belief that to successfully transmitt over a distance through the actual Earth without wire's, lower frequencies requiring fairly large coils will be needed. And a harmonic of the Earths frequency is desireable. I think. As suggested by lamare.

This might have something to do with the earlier point. I would also think that to tune it to the earth it would have to be pretty low frequency and big coils. I also never understood how if you tune your coil to quarter wavelength of the source you're tapping into, how could you possibly do that with light frequencies. The coil would have to be a speck

Warning Small rant

Don't get me started on those subjects

Oh and speaking of the field, it occurs to me if there is a field extending out 1 meter from my toroid terminal the toroid terminal should be at least more than 1 meter from the ground or other grounded objects even non or poorly conductive ones.

Excellent point.

However this will always be it's blessing or it's downfall. Unfortunately. No one wants to generate all the power when anybody can tap it anywhere in the world and use it.

But it would need to be tuned for this.

I agree. In reality it's a blessing, but given the current state of "national" consciousness, it's a downfall. If you're in competition because of this "country" concept then you have to keep the divisions and "independence" (by stealing foreign resources). So while a huge solar panel array in a vast desert where no one can live so wouldn't make the slightest bit of difference to the government or population of that country could solve all the energy problems of the world, it would also solve all the political problems of the world. IE make it irrelevant and get rid of it, and then the politicians would be out of a job, so they have to allow/create some problems so they look to their employer (the public) that they have something to fix and they're actually doing some work.

Now you got me started

[dR-Green]

Excelent, Considering the relatively small amount of power you're using you have good results already.

And use time to observe the setup over long time periods. Nothing much changes with time except the source battery voltage go's down. Unfortunately.

The one thing that puts me off doing something is the possibility/fact that I literally have to make it in order to find out the answer. I have plans for bigger spiral coils, and I also want to try cone shaped coils. But what size wire to use, what diameter windings, how to measure/weigh bigger amounts of wire to match the primary and secondary etc. The only solution I have is to build it and see how it turns out. Like with the spiral coils, I found, through winding wire onto the entire base, that that gauge wire was too long to fit and had to weigh thicker wire. So I need something more efficient I think I think the fact that the spiral coils are so closely matched is mostly pure fluke. 2 turn primary and 23.5 turn secondary, I couldn't have got it that close if I had tried. That's based on my suspicion that maybe 22.5 turns could be even more interesting But then the copper weight wouldn't be matched with the current measurements of everything.

One thing I worked out to keep the voltage down usefully is to use a cap pulser to float a battery from the receiver, it can charge a 7 aH in reasonable time but struggles to raise the voltage of a car battery thats drained but it will float charged ones at over 14 volts or whatever I set the pulser power to below that. This keeps the output loaded a bit so the LED's don't get too much voltage, I think 50 volts is too much for 6 x 5 mm LED's and a 1 K resistor.

This relates back to the earlier post as well, but I think, or it looks like, the output limits itself to the load I put on it. I haven't tried 1 LED on the output to see if it fries or not, but string LEDs which are from dismantled solar garden lights (single AA battery powered) work fine, with or without a resistance between the coils. I can't get a 12v motor to work on the receiver end yet. But then I guess the output is also AC and I haven't tried it with a diode. A rectifier seemed to cancel all effects and I got no output at all. [edit] Maybe it's also current related because I'm not really using much on the input. Come to think of it the motor alone probably uses as much if not more power than I'm using in total.

The LEDs don't seem to care for polarity (connected directly across the receiver "secondary" and caps). I can connect them in parallel or series, it makes no difference to the light output. I have yet to try anode to anode or cathode to cathode in series specifically to see if what one thinks should happen, will happen.

I ordered 100 meters of coax. to try for 100 meters transmission, but I want to improve my Toroid terminals first.

That would be good to see I tried a bit longer distance, I think I'll post that in a separate reply so I can also describe a bit of what's going on and what I didn't film.

I also need to setup a Plate 'P' radiant energy collector far enough from the coils to only get a bit of energy so I can try to work out the best way to use them, with Tesla coil nearby at least it is garanteed to work so I have somewhere to work from to improve how I do it and I can work inside. People are interested in the radiant energy collectors, me especially

Is that the quarter wavelength tuning thing I mentioned earlier?

My only concern is the slightly rough surface which shouldn't be a problem as long as the conductive tape tape sticks.

To stick my pipe insulation I wrapped two turns of strong duct tape around the outside to keep the ring shape, then wrap the whole thing up with the same tape. Then I covered all that with the flimsy aluminium tape so it had a smooth and somewhat harder surface to stick to.

This is the latest experiment I filmed. 2.2 metre distance first, then 6.7 metres.

Also not filmed is an approx 10 metre "transmission" through walls and floors. My room is at the top rear left of the house, and I took the receiver downstairs to the lower front right room, and it worked. Didn't spend too much time on it though because I had to run up and down the stairs adjusting things. I just saw that it worked and was satisfied with the result.

The "wireless" field that can put some light into an 8W fluorescent (though the wattage doesn't make much difference here because I'm not referring to fully lighting it) extends out maybe 2 inches at most, maybe a bit less than that. So I've seen enough to believe that the energy isn't technically or directly being transmitted through the air. Through removing the terminal on either side stops it all from working.
