This was a duplicate post as it did not seem to post when submitted, thus tried again, which is the next post.

It seems that the earth does act like a semi-conductor, at times.

Electron drift is normally defined relative to the conductivity of a specific material.

An excess of electrons is the subject of my post of 04/10/2004 09:35 PM and the general subject of this
thread. The geophysics model of the earth-astmosphere interface suggests the existence of excess
free electrons but I have found no studies (measurements) that confirm this phenomena.

[FrankM]

I should not have used the term "existence of excess free electrons" in the previous post. What the
geophysics model suggests is that geological and atmospheric events cause a "concentration of free
electrons" or a "concentration of positive charge carriers" at specific sub-surface locations for the
duration of an event. These "concentrations" should alter the apparent earth conductivity and should
be measureable.

The normal clear air (ambient) "concentration of free electrons" at the near earth surface would be that
which is induced by the normally positive ionosphere. Geologic and atmospheric events can alter the
"ambient" level of free electrons, thus changing conductivity.

I'm searching for references needed ascitations in a researchstudy,that clearly state that the surface of the earth has a negative charge. Some people refer to it asa slight negative charge.Guidance please.
Thanks,
Kay

You can start with the definitions maintained at the TexasA&M site.

<a target=_blank class=ftalternatingbarlinklarge href="http://www.met.tamu.edu/personnel/faculty/orville/Glossary.htm">http://www.met.tamu.edu/personnel/fa...e/Glossary.htm
</a>

The terms air--earth conduction current and air--earth current state that the earth is negative
relative to the ionosphere. Using the various descriptive terms associated with these definitions and others
in the glossary in a search-engine should help identify further references.

The TAMU site is primarily dealing with meteorology, but many of the definitions are shared with atmospheric
physics.

Sorry about the ads, Frank. I am simply trying out something on request from the ad agency. The problem is I have no idea what they look like since they obviously only show to people who are in the US. Could someone please send me a screen dump of what it looks like? It is not my intention to piss people off so if this is offensive it will be removed.

Only 5 words on each page should be marked, according to the agency.

The Edit process is now functioning normally.

The report cited below indicates that the conductivity of rock changes as a function of pressure, but the
conductivity is not the result of free electrons but due to positive holes (p-holes) released from the
crystalline structure. This indicates that within the earth there are slow but constant pressure changes
that can contribute to changing earth conductivity. The sudden pressure changes during an earthquake
cause extreme changes in conductivity.

The earth currents generated during the Chi Chi earthquake are estimated to have been from 10^6 to
10^ 8 amps.

Note the battery effect, but don't expect to hook up a wire to get a source of electricity.

I do not belief this is going to be the permanent location for the report, FF_iSTEP_2004.pdf, so
save it for your own reference.
