Dave,
As far as this subject is concerned about Tesla coils, I
think it is very important. For example, just by examining the
vary nature of how a capacitor works may leed to a very high Q energy
transfer system. Thus, we may obtain those high quantum efficiency's
we all dream of in a Tesla coil.
Second, you are correct in stating that absolutly everything
conducts electrons to some varying degree. And electrons do travel
along the borders (otherwise known the surface) of certain substances.
And in fact, electrons travel much faster along the surface of a
substance than trough it. The reasons for this are simple, the atoms
deep within a substance are pretty much engaged in the proccess of
bonding, ionic or valence. This tends to occupy the electron clouds
surrounding these atoms. But the atoms on the surface of a substance
are exposed to other possibilities. Like, receiving another electron
and becoming negatively charged or losing an electron and becoming
positively charged.
I think just the general understanding of how this proccess
works is essentail to how a capacitor works. And possibly, maybe a
better design for a Tesla coil could be developed.
