My question would be that at a distance of a few feet from the ground rods you might have a reading of 5 to 25 ohms but what about all the way back to where the soiled return path ground is connected at the power co. it has to be very high. and even though the voltage is high enough the power loss accross this resistance has to be high.even at the 19,100kv that cindy stated and at .5 amps \ 5 ohms would be about 1910 or almost 2kw of lost power that the power company has to generate for nothing. no wonder we have power shortages. and also this would only be good for 39.6 amps at 240v at the secondary side of the service. the loss will be much greater at higher loads. or Im I useing the wrong formula? but what a waste, like sparky said. and bill I could guarantee that no earth worms will live under this pole! lol
