What do you mean by this? Are you claiming that "if one amp were injected into the grid, the resulting voltage would be infinite"? That can only happen if the distance is infinite, and is really as much an objection to the concept of "infinite" as anything else. For a finite separation between the two significant nodes, the voltage must be finite. Or, are you instead saying that the proposed method yields infinite voltages for a finite separation? If so, I must confess that I did not observe it doing any such thing, and I'd like some explanation about how you get that result. Or did you really mean something else?
