This topic has aroused my curiosity. As a grounding device, why would a solid rod be better than a hollow
pipe, except for the current carrying capabilitY?

I would expect that a driven, solid rod would be in more intimate contact
with the earth while a water drilled pipe would have lots of surface air
gaps, at least initially.

After some period of time the gaps would fill in in most dirt and I
wouldn't expect there to be any difference.
