Jeanna,
Thankyou for that explination, TA.

@tishatang,
I have been looking for this for a couple of days. I posted it earlier but it always makes me smile. I think you will enjoy it too.

I believe this is the origin of the term "tank circuit".

From a lecture by N Tesla, delivered at Franklin Institute to a group of electrical engineers.

....by comparing the electrical
process with its mechanical analogue. The process may be illus-
trated in this manner.

Imagine a tank with a wide opening at
the bottom, which is kept closed by spring pressure, but so that
it snaps off suddenly when the liquid in the tank has reached a
certain height. Let the fluid be supplied to the tank by means
of a pipe feeding at a certain rate. When the critical height of
the liquid is reached, the spring gives way and the bottom of the
tank drops out. Instantly the liquid falls through the wide open-
ing, and the spring, reasserting itself, closes the bottom again.
The tank is now filled, and after a certain time interval the same
process is repeated. It is clear, that if the pipe feeds the fluid
quicker than the bottom outlet is capable of letting it pass
through, the bottom will remain off. and the tank will still overflow.
If the rates of supply are exactly equal, then the bottom lid will
remain partially open and no vibration of the same" and of the
liquid column will generally occur, though it might, if started by
some means. But if the inlet pipe does not feed the fluid fast
enough for the outlet, then there will be always vibration.
Again, in such case, each time the bottom flaps up or down, the
spring and the liquid column, if the pliability of the spring and
the inertia of the moving parts are properly chosen, will perform
independent vibrations. In this analogue the fluid may be lik-
ened to electricity or electrical energy, the tank to the condenser,
the spring to the dielectric, and the pipe to the conductor through
which electricity is supplied to the condenser. To make this
analogy quite complete it is necessary to make the assumption,
that the bottom, each time it gives way, is knocked violently
against a non-elastic stop, this impact involving some loss of en-
ergy ; and that, besides, some dissipation of energy results due to
frictional losses.
In the preceding analogue the liquid is supposed to be under a steady pressure....

It is so excellent, don't you agree?

I don't see your drawing on this thread of the motor idea.  Check your PM.  this site is having problems.  This past week the line item list of posts from today and a few days earlier is missing.  All I can do is click on unread posts and it list a few by block, not line item.  I am missing posts I believe.  Sometimes I can't access this site at all?  As a backup, I have belonged to energeticforum for some time.   See here:

Jeanna has recently joined.  Sometimes I explain things a little differently there than here depending on the questions asked.  Check it out.

I haven't read the quote before by Tesla.  It is very good.  I believe he is trying to explain resonant circuits.  Also what happens when you slam the door shut.  Electricity has inertia.  When hit hard, energy has to go somewhere.  When I first learned about electricity, the instructor used water and a pipe analogy.  The higher the tank of water, the higher the voltage potential.  The bigger the pipe diameter, the more current can flow.  Total energy (watts)  equals the amount of gallons of water can flow given the pressure and the size of the pipe.

I have been posting on the energeticforum in the earth battery topic for about a year.  Not as active as this forum by any means, but, good information to be sure.

I have had no problems with OU forum as of late, but, that does not mean others are not.

I have a problem with a bad ISP connection.  Sometimes it slows to less than dialup.  Plus everything here has to go thru the China FW.  It may depend on the country you are in and the servers getting the data there.  Others are complaining , so I am not alone.

I can't get youtube, metacafe, or even scribd.  Speaking of scribd, go here:

Search for the book called THE BOY ELECTRICIAN  by Alfred P. Morgan written 1913.  Give give you an idea of life back then.  And, some of the things Stubblefield would maybe have as far back as 1880.  Download and enjoy if you like to make things.  It is a DIY book.  Make coils, condensers Even a tesla coil.  Telephones and things like in NS time.  Unfortunately, no chapter on ground antennas. Highly recommend this book in your library.
