musstag said:The home next door to me has a older type high powered transmission line running alongside of a chain link fence. If you open the gate and slowly close the gate and watch as the latch again touches the post, you can see a spark. I told this to the Electrical supervisor, He said thats common, that he has seen a long roll of fencing strung out parallel to a regular power line that a farmer used to power a lite bulb for his barn from that roll of wire.
This is not even charge, it's caused by induction.

An electrical charge can travel through the air, and a signal travels through the air, and Both can be detected.
Eh? Are you suggesting that because birds travel through the air, and can be detected, that birds are therefore signals? Again,

So for you to say that an electrical charge and a signal is not at all the same, is false. Ignore the facts? Whose facts? What you think to be Fact may simply not be true.
Art's experiment detects static charge. Static charge is, errr, static... it envelopes the object and does not vary or propagate, therefore it is not a signal*. Much the same way that a static magnetic field envelops a magnet, but does not vary or propagate, and is therefore not a signal**.
You guys might want to think about picking up an introductory book on physics. This stuff is pretty basic.

* A signal is a varying "something" that conveys information.
** However, an AC magnetic field and an AC electric field can comprise a signal.
