Ghost Line
A ghost line is old method of sending signals through the earth. Originally, it was used for sending switched DC Morse code telegraph signals behind enemy lines because stringing telegraph lines across enemy lines was hazardous to ones health and they tended to get cut. I decided to try it with audio and it worked, I used it to send an audio signal about a mile, the signal was still robust at that distance and much greater distances are surely possible.
