Good enough for ground rods but my work at NASA, Goddard, shows even with the conductive salt poured into the hollow rods, it wasn't that great, seeing 4 and 5 volt digital pulses directly read off half inch thick ground plates around the walls of the lab showed that pretty clearly.

The resistance they measure is 10 to 1000 ohms/meter. That is NOT a great conductor and any technology using Earth ground to propagate electrical power would have to take that into careful consideration.
For one thing, suppose you put two ground rods one meter apart and measure say 100 ohms you will be heating up the ground if you try to conduct much energy through that medium.
If it is 100 ohms at one meter apart it would be 1000 ohms at ten meters apart, not a great way to transmit power. And that is only a few meters, a kilometer would clock in at that rate to 100,000 ohms.
But OF COURSE you know much better than any scientist.
