The Google search engine needs to "learn" the "best" places to go.  I am
not sure it is the best way to go for the archives.  It is very difficult
to teach it anything when one is randomly trying to find something...  It
works better for Google since everyone knows where they are going on the
big web, but does not seem to be very effective for the archives....  I
have years of posts in text format...  Maybe there is a better "system" to
apply to it...  If anyone has any ideas they can write me off list.  Chip
runs the pupman site, but maybe if we can come up with something better he
could change it.

Terry needs to work on insuring posts are "pertinent" more ;-))

Gravity and magnetic fields do not affect the coil in the way you mention.
We actually put "energy" into the secondary.  Current can't flow into the
ground without changing the voltage of the top terminal.  If current goes
out, it must also come in somewhere.  I am at a bit of a loss to explain
this through typed words.  It takes a lot of arm waving and diagrams.  A
tough question...  Maybe someone else can do better than me...

I used to search the text files for "keywords" that I knew were rather
specific to a topic, but I had already read them before.  Microsoft notepad
or any word processor that can deal with like 20Meg files can do that.  But
maybe there is a far better but still simple way to do it.  I am not a
programmer or search engine expert, but if someone has ideas, I have about
100++ Meg of files ;-))  Maybe it could all be burnt onto a CD or something.

The files are at:

http://hot-streamer-dot-com/TeslaCoils/Archives/

But probably best if I put them on CD and send them to anyone who wants to
play with them.  Chip has tons too...  Could be just a single giant text
file that a good search tool that does "and, or, not" could sift reasonably
quickly...  About 40,000 posts since mid 1999...  Chip has them back to
like 95...  It would be nice it they were all categorized and edited, but
that would be a horrific task!!  A program could do some logic like find
posts that are original (no "re:" in the subject) and then find the first
three replies.  Assuming if it had an answer, the "good" answer was given
quickly...  If you could then put the subjects in order and eliminate the
obvious ones (like "carp gap" :o)), you could probably get down to some
fundamental core posts and answers.  Best to search in reverse order since
some of the old 95, 96, 97... posts are pretty out of date...  Of course,
the possibilities and time one could spend on things like this is infinite
unless someone already has the method figured out...  Getting it onto a web
site also requires "skill"...

A lot of people have "started" these things, but it really is a BIG task...
 Just like writing that new Tesla book "sounds" easy, I am sure DC Cox and
John Couture could tell us how much effort it really takes!  I always got
overwhelmed at the "table of contents" stage ;-))

Getting multiple answers that are the same just goes with the territory.
Most people will answer right away and then find that some one said that 5
posts latter.  Just the way it is.  The Tesla list is a VERY busy mailing
list...  It is rather remarkable so many people put up with so many posts.
But it pretty much just seeks it's natural level...

Cheers,

	Terry
