I tried to try that. My plan was to use the house water pipes as a ground and a buried electrode as the active element. I went to the back of the property and dug a huge hole, filled it with aluminum foil and salt and several ground stakes. I waited a few days for it to settle and was ready to give it a try with a 48 watt audio amplifier but it was not to be. Turns out that my electrode was placed in an easement and the stars aligned such that a trencher ripped through my electrode while doing the install on a new gas distribution line just days after my installation. The workers probably thought they had plowed through a trash dump!
I never got a chance to try it for real. If I recall this method was used by hams during WW2 when on the air transmission was banned.
I also experimented with part 15 fuses for pyrotechnics, homemade and store bought. Things such as this would probably result in the young experimenter washing police cars these days. Back then, no one cared…it was part of growing up.
