If what you say is TRUE, then the rest of us should make it our business
to KILL you and everyone who KNOWS about your device.........

You have invented a GLOBAL Disaster, as if you pull energy from the
Earths Rotational Momentum, then the Earth will obviously STOP Spinning,
and Life as we know it will CEASE. Your Device is kill us ALL, and
therefore is actually WORSE, for humanity, than GLOBAL WARMING......

Let us all start the GLOBAL Angular Momentum Crisis Insitute to deal
with this MONUMENTAL Crisis, in the making. Maybe I can even win the
Nobel Peace Prize, for this idea......

Me who wonders just how stupid humanity really is......

Some guy named Einstein won a Nobel prize for proving that. He didn't
have any idea about physics either, the prize was in chemistry.

You ****ing assholes have no idea of science.




I'm Horvath and I approve of this post.



http://en.wikipedia.org/wiki/Density_of_air

"The addition of water vapor to air (making the air humid) reduces the
density of the air, which may at first appear contrary to logic.
This occurs because the molecular mass of water (18) is less than the
molecular mass of air (around 29). For any gas, at a given temperature and
pressure, the number of molecules present is constant for a particular
volume. So when water molecules (vapor) are introduced to the air, the
number of air molecules must reduce by the same number in a given volume,
without the pressure or temperature increasing. Hence the mass per unit
volume of the gas (its density) decreases."


Good point. The water vapor changes the density of air. BUT... water
vapor is not denser than air.

Water vapor is not denser than air is correct. Air is denser.

You have compelled me to reveal the device!

The device uses the rotation of the earth through its own magnetic field to
generate electricity. Such devices fall into the class of unipolar, or as
Gaynz prefers, homopolar generators. Faradays early devices used a fixed
magnet and rotating disc. However, the magnet can rotate with the disc as
shown in this reference:

http://www.physics.umd.edu/lecdem/ou...18unipolar.pdf

The earth has been modelled as a homopolar generator in the following
references:

http://www.spacedaily.com/news/earth-magnetic-00a.html

http://www.phy6.org/earthmag/dynamos2.htm

http://www.phy6.org/earthmag/dynamos.htm

So it is obvious to those practised in the art that a vertical conductor on
the earth's surface will develop a potential between the top and bottom of
the conductor due to unipolar induction. A radio tower develops a potential
between the bottom and top. Now, if the bottom of the tower is grounded and
the top designed to extract/feed free electrons from/to the atmosphere,
current will flow through the tower. A tower, a kite with a conducting
string, sea water all work also.

"Now why hasn't this been done before?", many of you are skeptically asking.
But it has:

http://en.wikipedia.org/wiki/Oleg_D._Jefimenko

He has written a book on the subject:

http://www.amazon.com/Electrostatic-...2573363&sr=1-6

As well as many other fine books:

http://www.amazon.com/s?ie=UTF8&sear...fimenko&page=1

Unfortunately the source of the current is incorrectly assigned to
"atmospheric electricity" rather than the unipolar effects of the earth
rotating through its magnetic field. Using the correct principle one can
properly design a collector tower capable of producing many amperes of
current for as long as the earth turns through its magnetic field. I have
built such a device and it has operated without interruption for years.

Unless the landing gear retract, there is not really that much difference.

The sign of a non-pilot. The difference doesn't seem large with
non-retractible gear, but it is extremely significant to a pilot trying
to get out of a tight spot, particularly if you add ground-effect (and
especially a sod runway) into the mix. It takes *energy* to spin those
little wheels up.

Short-field takeoffs depend upon getting the wheels off the ground
asap, even if the plane's not going fast enough to sustain free flight
at first. A short bit of level flight just above the deck increases
*acceleration* dramatically.

Really? Published much about it?

Let's have a little think, shall we? The earth's magnetic flux density
has a maximum of around 0.07 mT. The linear velocity of the earth at
the equator is 40,000km / 24 hrs = 462 m/s. The absolute best you can
therefore hope to achieve with a homopolar generator is 462 m/s * 0.07
mT = 0.03 V/m.

A 20m mast will therefore give you a whopping 0.6V (maximum) to play
with.

I missed the part where this has something to do with Nordhaven, or
even boats.

More like 12 000 volts.

The earth has an electrical field of, average, 200 volts per vertical
foot. You can be well zapped by the charge on tower that is insulated
from the ground. The object sucks electrons from the air, and although
you don't get much current, the juice accumulates, like static charges
do. This has **** all to do with the earths magnetic field, which
rotates with the earth.
