How about the capacitors and antennas on Voyager I and II which are still
operating at the edge of the solar system?

73, Cecil, w5dxp.com

You see the Voyager I and II use their metal structure as one plate of a
capacitor connecting to earth. The space between is the dielectric,


The dielectric is in the textbooks. In real space is the rare plazma
(conductor).
" Since plasmas contain equal numbers of electrons and ions, they are
electrically neutral overall and thus electric fields play a lesser
dynamical role. Because plasmas are highly conductive, any charge imbalances
are readily neutralised."

"Norwegian explorer and physicist Kristian Birkeland may have been the first
to predict that space is filled with plasma. He wrote in 1913: "It seems to
be a natural consequence of our points of view to assume that the whole of
space is filled with electrons and flying electric ions of all kinds. We
have assumed that each stellar system in evolutions throws off electric
corpuscles into space. It does not seem unreasonable therefore to think that
the greater part of the material masses in the universe is found, not in the
solar systems or nebulae, but in "empty" space."[1]["

Just as a mental exercise, assume that the entire setup...van and
antenna, is transported to a place in space where there is negligible
capacitance to the earth.

Is it your contention that the setup would operate any differently?


# The Earth is in the space and the entire setup also.
# The both need "neutralization" like the space-vehicle:
# "Other proposed applications of large-area field emission sources[39]
# include microwave generation, space-vehicle neutralization"
# From: http://en.wikipedia.org/wiki/Field_electron_emission
#
# " Where the electrons are compacted the electrons tend to push each
other
# off. Where there
# is a deficit of electrons, electrons are attracted from other sources".
#
# In space is the Solar wind (ions and electrons).
# S*

And if the van/antenna had been constructed on another planet before being
sent into space, is the earth still required or just the other planet?


# Each piece in the space is neutralized by the rare plazma.

Thanks. Your answer confirms many of my suspicions.

(Last year, I used a 20m dipole at 30 feet, operating out of my van.
Everything floated above ground without incident and many QSOs.)

I value your opiniion.


In Marconi opinion:
http://www.nobelprize.org/nobel_priz...ni-lecture.pdf


"By "connected to earth" I do not necessarily mean an ordinary metallic
connection as used for ordinary wire telegraphs.
The earth wire may have a condenser in series with it, or it may be
connected to what is really equivalent, a capacity area placed close
to the
surface
of the ground (Fig. 4).
It is now perfectly well known that a condenser, if large enough, does
not
prevent the passage of high frequency oscillations, and therefore in
these
cases
the earth is for all practical purposes connected to the antennae."


And Wiki:
"The use of the term ground (or earth) is so common in electrical and
electronics applications that circuits in portable electronic devices
such
as cell phones and media players as well as circuits in vehicles such as
ships, aircraft, and spacecraft may be spoken of as having a "ground"
connection without any actual connection to the Earth. This is usually a
large conductor attached to one side of the power supply (such as the
"ground plane" on a printed circuit board) which serves as the common
return
path for current from many different components in the circuit." From:
http://en.wikipedia.org/wiki/Ground_(electricity)

And of course there is the real problem. If he claims antennas work by
radiating electrons, why do insulated wires work?

I am going to love this answer.

All time the electrons flow to or from the ground.


Note the statement "makes it easier for a current to flow between the
plates". That's "between the plates" and not "flow to earth".


The Earth surface works as the plate.


And so it will have delay related to the transmitted frequency. So that
part will be predictable.

But you won't have a clue as to how it works, as usual.

He's been posting the same idiotic crap to multiple groups for years now.

I don't think he is a troll, I think he really is that stupid.

If electrons permeated space, all planets would be at the same electric
potential but we know they are not. How do you explain that?

Hi
Do you have any links about the relative potential of planets ?
I have always been wondering what would my meter indicate if
connected between an earth and a moon terminals.
On the other hand electrons move quite easily in vacum this was used
in radio not so long ago.
But of course much slowly than electromagnetic waves.

Light (and radio waves) are the oscillatory flow of electrons (L. Lorenz
1869).

Glass, ice and water are insulators.
As you probably know the wires insulated with the water do not work.
It is the wave lenght dependent.

Oh, that must be why light and radio waves do not pass through glass!
