This only can work because the long, thin coil will support slowly-moving electromagnetic waves,
and the electron-sea within the metal of this coil behaves as if it's become compressible...
The EM fields are transverse. And the only thing which acts like a "longitudinal" wave is the density of free electrons in the wire.}

That is what makes slow wave the group velocity
You can  write in YouTube  word "group velocity" to find easier  to understand material.

Wesley's contribution as an insightful deep thinking investigator has brought up very important points to take to the bench, his many lab experiments should be applauded.
Typical social engineering trying to get people to toss out the baby with the bathwater.  One must consider the source of derision, as there is an intended outcome.

Another possible challenge to the Corrum bros is the Robert T Hart patents for antenna design claiming mag field perturbation without EM radiation.  Claims are different workings similar at the surface boundary.  US20070013595A1  When tuning is correct reactance cancels EM component.

"The first objective of this article is to explain what surface plasmons and surface plasmon polaritons are. The term surface plasmons (SPs) was first coined in the middle of the 20th century to study the response of thin metal foils at petahertz frequencies when subjected to fast electron bombardment. SPs are coherent electron oscillations that exist at the interface between two materials where the real part of the permittivity changes sign across the interface. When an SP couples with a photon, the resulting hybrid excitation is called a surface plasmon polariton (SPP). SP refers to the charge oscillations alone, while SPP refers to the entire excitation of the charge oscillations and the electromagnetic (EM) wave. Under the right conditions, the photon can excite a longitudinal wave of electrons in the metal. The second objective is to describe the evolution of these concepts over the years and illustrate their relation to a surface wave and not to a Zenneck wave. Both Zenneck and surface waves are transverse magnetic (TM) waves. The surface waves thus cannot be excited by transverse EM (TEM) waves but rather by an electron beam that can be effectively generated by a source of electrons or a quasiparticle such as an evanescent wave, which can tunnel through the medium and thus excite the electrons. This electron wave produces its own EM wave, and this plasmonic wave is confined to a very small region near the interface. Hence, SPP is a surface wave with a longitudinal field component that propagates at the interface between a metal and a dielectric at petahertz when the conditions are right and can propagate along the metal-dielectric interface at a wavelength that is shorter than that of incident light until its energy is lost either via absorption in the conductivity of the metal or through radiation in free space. The longitudinal surface wave of an SPP is sometimes wrongly associated with a Zenneck wave. A Zenneck wave is produced at the zero of the reflection coefficient of a plane incident TM wave (at the Brewster angle of incidence) on an air-dielectric interface, whereas surface waves are produced when the TM reflection coefficient is infinite. Both the Zenneck wave and the surface wave are TM waves and are nonradiating, as they have, in general, exponentially decaying fields with distance. For the Zenneck wave, the evanescent transverse field components do not change appreciably with frequency (because the phenomenon of Brewster angle is independent of frequency), whereas for a surface wave, with an increase of the frequency the wave is more closely coupled to the surface. This property makes it possible to distinguish between these two evanescent waves. SPP is generally coupled with Raman scattering and not with Rayleigh scattering. These points are illustrated in the remainder of the article. Hence, surface plasmons/polaritrons are surface waves that are the solution of Maxwell's equations unless perhaps there is a resonant Raman scattering, which is equivalent to exciting the structure with an incident frequency corresponding to the electronic absorption bands, as illustrated in "A Survey of the Various Natures of Light Scattering"

I notice a lot of misinformation here and there.

A Zenneck surface wave is a planar electromagnetic wave that propagates at the boundary interface between two media with different dielectric constants. Instead of extending in 3D, it extends in 2D, with rapid attenuation when moving away perpendicular to the surface.
There is nothing new about this, it is always an electromagnetic wave with its electric field perpendicular to the surface and its magnetic field parallel to the surface.

It has been used since the beginning of the 20th century for long and medium wave radio transmissions. A hectometric frequency band has even been reserved for exclusive maritime use, due to the excellence of this type of propagation on the sea surface.
As always in radio where the signal weakens in 1/r², surface wave or not, it is therefore impossible to use these waves to transmit energy.

Tesla's transmission device has nothing to do with Zenneck's waves, because of the very low frequencies it used, which meant that the transmitter and receiver remained in the same near field, unlike the LW and MW radio waves. This was precisely the interest of the device, since the strong coupling obtained in this way made the transfer between transmitter and receiver much more efficient.
With very low frequencies, therefore very long wavelengths, it became possible to envision long distances while remaining in the near field. But it means forgetting that the efficiency of such a system depends on the size of the radiating elements, relative to the wavelength. If the Schumann frequencies were to be used efficiently, towers would have to be built whose height would represent at least 10% of the earth's radius!
Sorry for the believers in Tesla as God, but on long-distance energy transmission, Tesla screwed up, he was a much better engineer and inventor than a physicist.

hi F6FLT,

I think you have misinterpreted Tesla's method of transmission like the rest of the 99% typical crowd whom prefer to believe in Marconi whom applied "electromagnetic waves" for long distance radio communication.
Isn't that what we were taught.
But words like Zenneck's waves or maybe surface waves was not used during that era but that is not the point.

After Wesley have presented his

Zenneck[/color][/font][/size]

demonstration.

The first video i can directly associate/recall is Eric Dollard-Tesla's Longitudinal Electricity.
Before you start commenting on anything.
Please watch Eric dollard full video or start from 34minute into video as provided.

From the above video it's easy for me to understand which type of dielectric containing a particular noble gas can be used to enhance transmitting range better than what Wesley likely have used for the recent zenneck video which is already considered a successfully replicated demo model.   

I do admit one thing-surface wave even if fully understood can't be used for interstellar communication.

Gabriel Kron said his network analyzer for the navy worked without the power source after it was started from battery. He said negative resistors exist and open circuits using them is the answer.

Trying to hunt down his paper where he said this, but it seems every archive has the other papers and not his...

The Tensor is the Tensor society's paper and this paper is from 1963-64

He also said that in systems theory it is customary to replace negative resistance with a capacitor and positive with a inductor. Then he said that if the system appears to have a negative resistance in it, it behaves like there is one. So no "actual" component is necessary, if the system thinks there is one.

Also interesting that only reference to Kron's paper is in Bearden's page and the reference to that paper says "unknown". Everybody else references Bearden. Took me a while to track down which paper Bearden was referring to
