Some years back I buried a 30 metre (60-feet) auminium wire one spade
depth in my back garden. Wire was 1.5 mm in diameter. Soil
resistivity about 100 ohm-metres. To scientists that's 10
milli-Siemens. The near end of the wire came up in the shack. That's
under my kitchen sink. It's still there. Open-circuit at the far end.

Reg, was that 30 meters and 90 feet or 60 feet and 20 meters? Just for us
mathematically challenged.
