Somewhat more seriously, I've been reading about nantennas for solar
power. With 85% theoretical efficiency, it sure looks promising.

http://www.inl.gov/pdfs/nantenna.pdf
Maybe there's a place for RF engineers in alternative energy. All I
need to do is build a 3,000GHz antenna farm and find a diode that
works at that frequency.


The principle of nantenas is the same as the crystal radio.
The size of the antenna must be below 1/2 WL.

For RF each diode is O.K.

The question is if the electrons flow into the ground.

Do you know the answer?

Not quite.

Nope.

Babble.

The question is if you can tie your own shoes.

Do you know the answer?


Yes, most all of us know the answers.

It is only you that is totally lost in babbling nonsense.

Please read the PDF I included. The length of the dipole can be any
multiple of 1/2 wavelength. It can also be a loop antenna. What's
critical is the spacing between the antenna and the underlying ground
plane, which form a resonant cavity at optical frequencies.

For RF each diode is O.K.


Please read the Wikipedia article:
The large loss in power is a result of the junction
capacitance (also known as parasitic capacitance) found
in p-n junction diodes and Schottky diodes, which can
only operate effectively at frequencies less than 5 THz.[3]
The ideal wavelengths of 0.4-1.6 um correspond to
frequencies of approximately 190-750 THz, which is much
larger than the capabilities of typical diodes. etc...
This isn't going to work with ordinary diodes.

The question is if the electrons flow into the ground.


Nope. The question is whether there are any electrons involved. There
are none.

Do you know the answer?


Yes... I know everything. If you unable to form a suitable opinion, I
would be happy to supply one for you.

Everyone constantly repeating that there are no electrons falling to
the ground or spewn into the air doesn't seem to have much of an
effect on you. You are also apparently incapable of answering my
question (multiple times). I see no indication that you have read,
much less understand, any of the references and explanations supplied
for your benefit. You are therefore hopeless and a waste of time.

RF = radio frequency.

Nope. The question is whether there are any electrons involved. There

"The simplest crystal radio receiver, employing an antenna and a
demodulating diode (rectifier), is actually a rectenna - although it
discards the DC component before sending the signal to the earphones. People
living near strong radio transmitters would occasionally discover that with
a long receiving antenna, they could get enough electric power to light a
light bulb"

Where the DC component is discard?
What is the DC component made of?

Do you know the answer?

"The electrical grid, which is normally three-phase AC, can be severely
disrupted by the presence of a large DC bias. This is caused by strong solar
flares hitting the Earth's atmosphere,(Even pipelines, such as the mostly
above-groundAlaska Pipeline, are prone to this, and must be tied to
electrical ground".

Now you are only one. Two days ago Jimp wrote:
"It has been explained to you several times that any electron emmission
from the ends of an antenna is an abnormal situation, is NOT required
for antenna operation, and is an independant phenomena of normal antenna
operation."

So we have done the first step: "electrons falling to the ground or spewn
into the air" are the abnormal situations".

The next step will be "L. Lorenz is right".

The electrical grid has nothing to do with antennas and the structures
being discussed are usually miles long in size.

There are no antennas miles long in size.

No, we do not.

Even in a solar flare there are no "electrons falling to the ground or
spewn into the air".

Solar flare effects at ground level are magnetic effects.

The next step should be to get you into a mental hospital.

Thanks. There's an all too common misconception that the engergetic
charged particles produced by solar flares, solar storms, solar wind,
CME's, etc somehow land on the power lines, which then appears as a DC
voltage on the lines. That's not how it works at ground level. This
explains it better than I could:
http://en.wikipedia.org/wiki/Geomagnetically_induced_current


I can almost guarantee our babbling Polish idiot believes that solar
produced particles make it through the atmosphere, which they do not.

All that energetic crap from space winds up being trapped by the air in the
upper atmosphere, ionizing the air from about 85 km to 600 km in altitude,
which is why the ionosphere exists.


It occurs to me I should probably define the term "energetic crap from
space".

What is meant is any particle or EMR with sufficient energy to knock an
electron off of an atom.

For EMR, that starts in the UV region, which is the primary source for the
ionosphere under normal conditions.

During solar flares, there are LOTS of high energy particles being ejected
by the Sun of sufficient energy which add to the mix.

For an off topic amusement:

I did a search for our babbling Polish friend and the first thing I found
was a message posted to a Polish medical list where he claims all cancer
is a fungus and should be treated with Epsom salts.

It appears his idiocy is boundless.
