While searching for info on electrical charge distribution at the earth's surface, I identified an application that uses the earth as a near perfect conductor.
When One Wire Is Enough (html)
Single Wire Earth Returns (1.534 MB pdf)
It is a working application that can't be disputed, but I cannot find a geophysics source that identifies the theory for the near perfect conduction. The pdf article notes that the engineers used 0.05 ohms/km at 50 Hz for the design model. All of my reference sources indicate that earth resistance is quite high. Am I missing something, as it seems the earth conduction is different from earth resistance?
Any sources for the earth conduction theory?
