Steve ... be careful of your knowledge.
The study I based my comments upon used solid stainless, in both rod and plate form, in Southern Nevada and Southern California. In this study, even after only five years, very little was left of the electrodes.
As I mentioned, there's a lot that is not yet known. I suspect we'll find that there is no such thing as a 'good everywhere, all the time' material.
I also suspect that a lot of what we "know" about ground rods, etc., is based more upon 'logic' than actual experimentation ..... not to mention outdated theories and assumptions.
