Kapanadze and other FE discussion

[stivep]

Hi stivep,
Satellite as you already knew with the main component magnetron which the electron velocity is accelerated without the need for "Earth grounding" or counterpoise.

Satellites operates in microwave region of frequency range.
AM broadcasting stations operates at LF or VLF frequency range.
and dish antenna is a parabolic reflector not the quarter wave dipole

The subject of video in question was telluric current .
_{https://www.youtube.com/watch?v=A8zoEMkuqiQ}
The statement in the video was claiming involvement of the telluric current as a primary mechanism
of receiving local AM radio station  of about 2.5 kW power PRP.
Experimenter used:
1. a conductor (wire) immersed in the water from the lake.( basin, River)as an antenna connected to ham radio transceiver.
and then:
2. coil serving as an antenna connected to inner  of the  of   Rx/Tx PL 259 connector of a ham radio transceiver, while shield
(the outer part of  PL 259 was connected to the ground  immersed in the water from the lake.
_{https://www.arcantenna.com/blogs/news/uhf-pl259-so239-what-is-the-difference}
That  made a traditional vertical dipole configuration.
( look at the position- of the coil that is vertically polarized.
_{It means:
vertical piece of wire was coiled to take less of a vertical  height  like car antenna})

The  AM band is covering width  in the range of 500 kHz up to ~ 2 megahertz
_{https://www.dxing.com/amband.htm}
The video content maker,:
-failed to explain the interaction of electromagnetic wave at frequency of ~500 kHz with the telluric current  at the depth of
~1-5 m,. 
-failed to explain what role in the process of receiving signal the telluric current has there?

telluric  current phenomena – has not much to do with ground wave reception.
Local AM radio station transmitted signal  - has nothing to do with telluric current,

If there was Earth grounding involved as the requirement i would not be interested in the kapanadze device a long time ago.

at 20th floor of the building artificial ground works as well.
Think about ground and artificial ground as a balance or counterpoise
_{and as a part of antenna radiative system.

This is why I don't care who said what or how they said it. I only look at whether something is reasonable, reflects the reality of a given situation and is free of contradictions.

I agree that you don't care and that you don't know.
I agree that you have a rights to your point of view.
We are standing at a certain level of scientific achievement, and my response is based on its statements for today.
We know that mechanical waves can't exist without a medium!
Based on science we know that electromagnetic wave doesn't need any medium to travel.

This energy can be described by frequency, wavelength, or energy.
Electromagnetic waves are produced due to the timely change in the electric and magnetic fields and depending on the periodic change power is generated in the field.
- as a result of vibrations between an electric field and a magnetic field.
Electromagnetic waves do not require a medium such as air, so they can transfer energy through vacuum, or empty space.
In a vacuum, all electromagnetic waves travel at 3 × 10 8 m s − 1 – the fastest speed possible.

"Similar phenomena were noted, greatly magnified in intensity, but they were susceptible of a different and more plausible explanation. I considered this so important that in 1892 I went to Bonn, Germany, to confer with Dr. Hertz in regard to my observations. He seemed disappointed to such a degree that I re- gretted my trip and parted from him sor- rowfully. During the succeeding years I made numerous experiments with the same object, but the results were uniformly nega- tive. In 1900, however, after I had evolved a wireless transmitter which enabled me to obtain electro-magnetic activities of many millions of horse-power, I made a last des- perate attempt to prove that the disturb- ances emanating from the oscillator were ether vibrations akin to those of light, but met again with utter failure. For more than eighteen years I have been reading treat- ises, reports of scientific transactions, and articles on Hertz-wave telegraphy, to keep myself informed. but they have always im- prest me like works of fiction.
The history of science shows that theo- ries are perishable. With every new truth that is revealed we get a better under- standing of Nature and our conceptions and views are modified. Dr. Hertz did not discover a new principle...."

Why, then, does a quantum of infrared radiation heat body up when absorbed, for example, by a completely black body more than the same quantum of ultraviolet ?
The energy of the ultraviolet quantum should be many times greater.

One UV  (ultraviolet) photon has more energy than one IR  (infrared) photon.
https://www.quora.com/Radiation-Which-carries-more-energy-infrared-or-ultraviolet-How

probably the confusing factor for you is that you take big number of infrared photons
and trying to compare it with one photon of ultraviolet.
The higher is the frequency, / the shorter is the wavelength  the more energy per  period is there.
so one photon of gamma ray  has more energy per period then one ultraviolet  photon .

That explains why electromagnetic waves below the range of visible light are harmless to a human body.
Because they have very little energy per period.
However you need also to understand the intensity. _{at the given point( distance) from the radiation source (e.g antenna)}
it was clearly visible at antennas of Russian radio location systems(radars)
example:
if a soldier was fixing something in the middle of an antenna dish of Russian  "Zoska"  or "Natasha" operating at only few hundred megahertz frequency band.
and the other one accidentally switched ON the power than this soldier on the antenna was simply cooked.
but because of inverse square law if he was 10 feet away he had a very much guaranteed
survival.
Another factor is length of exposure. it can be compared with "cooking" the water where it takes time before water is boiling.
I hope it helps.
