From the article:
QuoteOur modeling and simulation using Maxwells equation with proper boundary conditions shows Zenneck type behavior for the excited waves and are in excellent agreement with experimental results. In conclusion, we physically realize a radically different power transfer system, based on a wave, whose existence has been fiercely debated for over a century.
Interesting, but is there any discussion or better, demonstration - of an OU effect?
https://www.youtube.com/watch?v=XOTLfnMOSqQ&feature=youtu.be&t=1003
at 7 minute mark [approx]
Wesley shows 1200 foot transmission with 20 watts input
at 16:43 mark what he refers to as "activation" which is said to interact with
energy within the planet [natural occurring Zenneck within the shuman ??
this "activation" part is where additional energy enters the system .
as of this writing , specific method to "activate" has not been shared in a "how to"
format.
but apparently all that is needed has been posted at Wesley Blog at Stefan's forum.
I believe Wesley is maintaining agreement with fellow researcher in Germany
who did the actual testing to realize the activation process and additional energy.
he is asking for permission to share the specifics.
Extracting energy from the Schumann Resonances (https://en.wikipedia.org/wiki/Schumann_resonances) is an
interesting hypothesis, but is it even practicable?
What is the energy density of the frequencies which occur
within the ELF band from 3 Hz to 60 Hz? Sufficient to
enable "harvesting" watts of power with a "receiving"
device of some sort?
Aren't the Schumann frequencies rather weak? Powered
by Lightning, the original "Spark Gap Transmitter."
The tower built in Texas is designed to operate at approx.
18 KHz which is much higher than the Schumann frequencies
but, interestingly, within the range of frequencies used to
world-wide communicate with submerged submarines in the
oceans of the Planet.
Food for thought...
If not Schumann, what else might it be?
I have heard that there is a layer of natural Zenneck waves that runs right along the surface [under our feet ?] in Telluric currents....??
in an area smaller than the space between two pinched fingers [crazy small space]
and the magnetic attribute of this "Zenneck zone" is most important for harvesting,
one thing for certain
we will be learning much more about the different energy transmitting / harvesting methods here .[good or bad]
whether true FE as in a heretofore unrealized energy source,
or is it harvesting unbeknownst from the grid or "other" ??
we shall see ??
Eric Dollard has some papers related to this phenomena that may prove useful for people researching this field.
Theory of Wireless Power:
http://ericpdollard.com/wp-content/uploads/2018/04/theory_of_wireless_power_eric_dollard.pdf
Transmission and Reception of Telluric Waves:
http://gestaltreality.com/downloads/The%20Transmission%20and%20Reception%20of%20Telluric%20Waves%20-%20N6KPH%20-%20collected%20posts.pdf
It would appear these telluric systems operate predominantly through displacement currents and impulses rather than conventionally radiated electro-magnetic waves. As the dielectric losses of the Earth are potentially lower than the resistive losses, a higher-efficiency transmission would appear to be possible.
The propagation velocity of such a system would also be difficult to determine since the Coulomb force is considered to be a scalar with no defined velocity.
a build topic on this subject is to be started at Stefans
with member [and moderator] Gotoluc hosting.
the goal being a working Zenneck "far field" transmitter [Courum 2007].
can transmit energy for thousands of miles ??
it is said that this evolved into Tariels "direct access" Zenneck interface receiver [no transmitter required].
this Zenneck interface area is said to have amounts of energy beyond explanation
or unlimited ??
this is _new news_ and a remarkable claim.
nothing but Gratitude here.
MuDped yes ELF seems a big part of this.
Reiyuki , thank you for the contributions .
Don't know if this helps but I find in my archives the following paper about Zenneck Waves.
I note that the Zenneck wave occurs at the boundary between two different materials and requires the permittivity of one of the materials to be either negative or to have an imaginary component. If the earth is that material then it requires its permittivity to be either negative (which it isn't) or to have an imaginary component which is equivalent to saying it is lossy (which it is).

Very interesting paper, Smudge - thank you!
https://youtu.be/cuf0zRYwJak Apparently viziv is already doing it? http://vizivtechnologies.com/ https://www.youtube.com/watch?v=wFiW2lqdnlM edit: Everyone was already aware of this mob :) Sorry late to convo.
Watching the video and you have to admit it's pretty darn cool that Tesla's claim was true... the present may be there's but the future is mine. Politicians and corporations have a limited lifespan but a good idea, a concept is eternal. Also strange that there is little or no mention of Nikola Tesla in the video or on the website. They do understand that Tesla perfected this system before most of them were even born don't they?... lol.
Both videos; The Texas Tower (https://www.youtube.com/watch?v=cuf0zRYwJak&feature=youtu.be) and Emerging Energy Technologies (https://www.youtube.com/watch?v=wFiW2lqdnlM),
are very informative. :)
Will the Texas Tower have success in the stated objective of
beaming power to distant locations? I am skeptical and doubtful. ???
Will the Texas Tower create an atmospheric channel of conductivity
to discharge some of the Sun Powered Atmospheric Capacitor? ???
I believe so. It may experience the same sort of power surges that
Tesla experienced with his work in Colorado. Hopefully, the Texas
Tower will have the ability to transform the Energy Surge from the
Atmospheric Capacitor into Electrical Power suitable for use by
the People. That will be a very great challenge. 8)
One of the speakers mentioned the dilemma in Germany where the
Political sector, which is heavily influenced by Corrupt Corporations,
made what seems now a wrong decision. Sadly, in America, that
Political Power of Corruption is even stronger and may put the
kerbosh on dreams of abundant, carbon free, low cost energy. >:(
The Love of Money Corrupt Corporations will be "the deciders." :(
Strangely enough I had a similar setup on my bench this spring.
Note the large fiberglass tower with the large top load as well as the second skinny tower with a torus top load. The second tower is the trigger for the first tower as well as being part of the feedback loop. However what is not seen and rarely mentioned is the extra coil(s) which helps produce a high magnitude Solition wave. In my opinion the Zenneck wave is a red herring so the Corum brothers and Viziv can distance themselves from the discovery first made by Nikola Tesla.
The upside is that Nikola Tesla already has prior art and patents to support his claims so anyone can replicate and commercialize this system. I wonder if the Corum brothers informed all their investors of this fact... I'm going to guess not. I may have to dust off some equipment and start my own company if this thing looks like it's going to take off, hmm. Personally I can't see it happening any time soon because the utilities have a trillion dollars or so invested in antiquated transmission line systems. Everyone is still throwing up more towers and more wires all over the place as we speak. It's kind of comical that there idea of "common sense" is to keep building more and more towers and wires until the whole planet is probably covered in them. Common sense?... right.
So it should be understood this is not just an ordinary Tesla coil with a feedback loop and most skilled in the art know that this will not produce the wave properties required. I have built many Tesla coils with and without feedback and they cannot produce the desired effects alone without additional components. As always one has to actually build these devices and test them and also learn to follow directions from the persons who actually invented the technology.

Why not dust the equipment off right away and see/show us whether your setup really "works"?
Why wait?
--> I give the same challenge to myself, incidentally - on a different technology I've been working on, set aside for awhile, need to get back to it pronto!
Their omission was glaring. For more watch stivep1 (Wesley ) on yt. Some good info. I've dusted off my coils Steve. My circuit has a transistor and two coils. Sometimes a resistor. I like to keep it simple :)

There seems to be no OU effect. The idea is to transmit electric power over wider distances than efficiently possible by induction. But there are always losses, like with induction.

Lucs experiment atm is to show one wire transfer of power without a return path. He has eliminated wireless capacitance by placing his generator in a faraday cage. Wesley explains a lot in the vids.
Hi guys,
As this keeps coming back, I can share my guess what "activation" process is.
First at all no closed loop circuit can produce more energy than primary energy source puts in. But this is not a case when it is mixed with open circuit which is interacting with ambient.
So, starting with small step one - when you run Tesla coil off the battery it still have sparking to the ground, right? This is where secondary power source becomes apparent and all you need is just to amplify effect. Basically this is part of "activation" process, simple as all Nature is.
Moving to step two - have Avramenko plug for charge separation on single wire and connect Tesla coil primary to it over capacitor discharge with interrupter(rotary/magnetic spark gap in Tesla days). The secondary ground connection is the second wire to the circuit. What it makes essentially is capacitor to the primary power source which separates the rest of circuit from it. But because of coils used as capacitor plates it also have inductance so with the charges discharging to the primary from Avramenko plug you will still have power output on the secondary. The beauty of that is, it is already electrostatic arrangement between air and ground and is quite straight forward when you start attracting ions from surrounding air and electrons from ground then create dipole. Which can power your loads.
P.S> this was already done back in 2010 Lithuania Experiment by me, Aidas and Wesley (as reporter) - https://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg539481/#msg539481
Good luck!
I've dusted off some old coils and circuit which is just a mje3055t and a 2.4k resistor. I'm trying to understand why I get "better" results by using an antique ac/dc power supply . Dc is actually half rectified ac. The rectifier is not familiar to me. It measures 6vdc on a dmm, uses about 80ma measured by an analogue panel meter. My normal dc power supply at 12vdc using 140ma does not produce anywhere near the plasma or field. I'd like to understand why that is the case. I can't get the same effect with modern ac stepdown transformers and a power diode.

Hmmm. There must be an explanation. ???
Old is better? ;D
Mysteries are good exercises for the brain. 8)
I'm thinking it may have to do with the way they are grounded but will have to destroy one to find out :)
A weird half rectifier. Be interested reading about this but not sure what it's called. 15ac in 12v half rectified ac out. The rectifier seems to over heat and a thermal switch throws.
Hi Jimboot,
As best I can tell from the picture the plates inside the housing appear to be a selenium rectifier. And yes they did run hot and if one overheats to the point of burning the fumes ARE toxic. They were rather inefficient and were replaced by the more modern and more efficient silicon pn junction diodes commonly used today.

Yikes! Thanks for the tip Carroll
I didn't mean to alarm you unnecessarily. The fumes are not so deadly a couple of breathes will kill you, but the fumes are considered to be bad for your heath. And the smell is so bad you won't stick around long to continue breathing the fumes. Back in the 1950's my dad repaired radios and tvs. At that time the selenium rectifiers were commonly used. I still have some of them from his old stock of parts.
My dad was an electrical engineer and he had lots of plates from those old selenium rectifiers. He use to carefully heat them with a blow torch to get to the temperature where the solder coating on the selenium melted and he could wipe it off. He then had photocells that he could use on various projects. Early solar cell arrays back in the 1950's!!

I love stories like that. The little things that will be lost to time. Given selenium rectifiers forward voltage drop, it make the perfomance even more curious. I'll swap it out for a power diode and compare the difference.

Thanks I read up about them last night. Interesting stuff.
In the 50s and 60s they were often referred to as
Selenium Dry Disk Rectifiers (http://unisourcetechnologies.com/family/Rectifiers.htm). They were very common
in military electronics back then until "field changes"
were accomplished to replace them with the new
Silicon Rectifiers in the mid 60s.
Copper Oxide rectifiers were frequently encountered
back in those years as well.
The Electrolytic Rectifier (https://chestofbooks.com/crafts/popular-mechanics/The-Boy-Mechanic-700-Things-for-Boys-to-Do/How-To-Make-An-Electrolytic-Rectifier.html) was very much used by
experimenters and Ham Radio Operators for projects
because they were easy to put together and very
inexpensive. Bulky and not too efficient but cheap.

Thanks mate now I want to make one. :)
On the very long list of things I don't understand. I've been trying different power supplies with my Zenneck coils experiment. I don't understand how this selenium rectifier is delivering results that a power diode does not. Happy to do a vid.
I'm measuring the 16VAC output of the transformer in parallel to the rectifier.
The circuit only oscillates when the rectifier is in the circuit.
The DC output on a DMM is around 8V or 16VAC on same DMM. It gets better results than by DC power supply at 12VDC . Stronger field more plasma etc.
JimBoot,
Does your Oscillator require a certain specific
minimum Input Voltage to start oscillations?
Once oscillating, are the oscillations continuous
or pulsating in sync with the DC Input pulsations?
Or, are the oscillations effectively Amplitude Modulated
by the input voltage wave-shape?
A video would be very helpful and will, no doubt,
reveal the answer to the puzzle. Possibly a
comparison of Old vs. New?
Also, could you show us the schematic diagram of
of your Oscillator?
With the dc supply it takes at least 12v for oscillations 150ma. Continuous oscillation. With half rectified ac nothing on other adapters or the the power supply above. It's only when the rectifier is part of the circuit. I see 50hz flickering when activated via the rectifier.
I'll do a vid bit later. Not sure about the amp modulation.

A comment from Tinsel

12:24 PM (4 hours ago)
to me
Ask Jim to check his wiring and his photo labels.
I don't see any difference between two shots that should show a
difference according to the labels. Also it may be the case that his
old selenium rectifier is leaky or otherwise malfing. Those things are
weird. He could probably model it in his hardware by putting a
resistor across his silicon power diode, maybe.
I'm sure it's malfunctioning. There is a difference in the images. https://youtu.be/_odJBpkGfrw?t=155 . You can see the change as I add the diode at the 2:36 mark. Thanks for taking a look TK.
Hey Jim

Your scope looks similar to mine, Rigol 1054Z?.
The thing about scopes is to understand what your actually seeing vs what you think your seeing. Now you say the output is around 16 VAC however in pic 3 with just the rectifier the Max peak to peak voltage on your scope shows 358 V. If the rectifier has a lower voltage rating then the current will flow both directions (AC) through the rectifier until it drops below the rectifier threshold voltage. What is the voltage rating of the rectifier?, did you test each rectifier leg for continuity?.
Sometimes I get lazy and just drop in an under rated diode or backwards diode/clipper and capacitor as a negative resistance to produce oscillations. In fact you can chop any circuit leg(s) and mix frequencies this way, pretty neat stuff. I have also smoked a diode with an over voltage, measured the new threshold and used it at the new lower rating elsewhere. Semiconductors can do weird unexpected things when they have been damaged.
Then when you add a power diode in the video it is in series with your scope probe so of course it will chop the AC into DC... but only to the probe not the circuit. Your circuit may still be operating on AC however your probe with the diode will show DC because you have only rectified the probe voltage.
As I said, it can be tricky and first we have to determine what it is we are actually measuring at the probe connection. Then we have to be pay attention to what the values are as well as the waveform.

Hi Chet I pointed out in the Thread 'The free energy circus' big oil and their cartels socio political miss direction applied to all major free energy forums .
The 'hands across the world '-wesleys-kapanadze - debacle is absolutely a classic example of this costly mind numbing crap .
I hunted for and exposed this Kapanadze cartel and oil company generated sewage for what it is some years ago,I revisited those posts over on energetics hoping to show you .
I found some of the pictures I posted removed,so I re linked to them. FYI here is my comment and a link to those damming pictures. and a thread I brought to a screeching halt .

Then make a note of Kapanadze - Wesley and all the other well paid tricky bastard monkeys identify them by any and all means and exclude them all from everything you consider at every possible turn in the future. certainly don't want any of these creeps near this forum.

Yep same scope . :) I did not test the rectifiers legs. I observed the 358v and atm I think it is just the scopes' inability to measure it. I have tested other modern AC step down transformers on the same channel with the same lead. The voltage measurement on the scope is as expected. My transistor would be fried at that voltage but it runs cool.
In the video the circuit was not operating as I do not want to damage my scope. In tests the scope is replaced with the circuit. I can run the circuit with the selenium rectifier in parallel, with and without power diode. That is what those waveforms are showing. The second image has no power diode and the rectifier is in parallel. The circuit oscillates. It does not with normal AC.
It looks as if some reverse voltage is getting through to create spiked waveform? The rectifier seems to add a load but I have not measured it. This is why I think it is faulty. I think I need to measure the load it adds.
JimBoot,
Has your 2.48K base bias resistor been selected as an
optimized value for a specific voltage range?
Do you think that a variable resistance in place of the
fixed 2.48K may offer enhanced versatility?
The difference the two supplies make in current drawn
by the circuit may be of some significance.

The Circuit is one of Laurent's from years ago. I can certainly swap in pot and check. Thanks.
I've been testing the rectifier with two modern AC - AC transformers and have burnt out both. I get the same effect though as using the PS original transformer.
So if the rectifier is breaking down and presumably drawing too much current from the the AC source,
1. why does it's half rectified output work so well when a power diode does not?
2. why does it work when connected to the rectifier in parallel when it doesn't have an external load?
The exciter circuit draws 100ma whether it is connected parallel or series with the rectifier measured with a DC panel meter.

It's debatable, I believe your using a 3055 which is a real workhorse and takes an absurd amount of abuse. As well a NPN or PNP transistor is basically two diodes back to back which is how we test them. So a fast transient could appear as a higher voltage across the internal "diode" and/or circuit leg because of it's resistance.

Ah, okay, if the rectifier is in parallel then I suspect it's breaking down and either clipping the AC and/or producing an inductive discharge from the transformer oscillating through the circuit. Like a variable voltage switch which only comes on/breaks down when a given voltage is exceeded.
QuoteIt looks as if some reverse voltage is getting through to create spiked waveform? The rectifier seems to add a load but I have not measured it. This is why I think it is faulty. I think I need to measure the load it adds.
An inductive discharge will reverse the voltage signs but the electron current does not reverse. The only way to really tell is to measure both the voltage and current simultaneously. I like to use a hall effect current sensor for isolation and to avoid HV spikes and ground currents through the scope... not cool. You can also use an opto-isolator/voltage divider circuit to isolate your scope from the circuit.

These posts are getting a little off topic but if you are interested in these Zenneck Wave functions there are some simple thought experiments one can do.
In my opinion it's important to concentrate on key words, ie. Quote: "The Zenneck wave, Zenneck surface wave or Sommerfeld-Zenneck surface wave is a longitudinal, inhomogeneous or non-uniform electromagnetic plane wave". So what are the key words?, longitudinal and non-uniform stand out in my opinion. It stands out in my mind because of my research in Weber Electrodynamics which Maxwell discarded in his work. There is in fact a completely different set of theory which remains obscure but is no less relevant in Weber's work.
Think of it this way Jim, we take a string 2m long attached to a wall and we give it a snap. The string takes the form of a sine wave, the wave moving back and forth, up and down in known ways. However what Weber was proposing was that we could give the string a snap, let go and the string would propel itself forward due to it's own inherent kinetic energy as a singular object not unlike a baseball. The string keeps oscillating however it is not attached to anything thus it's energy can only act in the same direction it is traveling thus it must be "longitudinal" in it's nature. Longitudinal simply means, acting in the same direction something it is travelling.
Think about that, we snap a string producing a sine wave like motion we all know ... but then we let go of the string and the energy of the string becomes an entity, a force, in and of itself because it is detached from everything else. So what is it?, in all my research there is only one definition that describes this and it is a Solition wave. As such the only real question which remains is how can we reproduce this effect in an electrical device in the real world.
I'm just not sure I understand how your textbook AC rectifier problem relates to our problem with sending megawatts of power thousands of miles without wires.

As I said if it considered OT mods should remove. Wesley stated in another thread that using a spark gap to power tower will introduce a greater range of frequencies. Before I move onto that I'm trying to understand what's happening here. I'm curious to know if either phase shift or or something with going on with the signal is worthy of further investigation. I'm a dog with a bone. I don't think it's the transients but I have no real data to support that. I appreciate you taking a look. This power supply has intrigued me for some time. Here it is from 8 years ago when it was working properly. The video is a mess and it was in a very small space. Looking back at the plasma spewing off this coil amazes me looking back now. https://www.youtube.com/watch?v=Z6T8vutgPHY
