I am serious. The topic of UFER, ground rods and safety ground "systems".
Would those of us with good soil benefit from boring a 6, 8, or 10"
hole, filling it with concrete and sinking the ground rod in it? The
contact area is small, but huge compared to the rod accompanied by a low
inductance. It seems, at least in theory that the ground system could
be reduced in size (number of rods) while possibly increasing the
effectiveness of the system. A mini UFER ground system network. At
first, it sounds like a lot of effort and cost, but out in the country,
most of the equipment (Tractor mounted) is relatively common while those
in the city could put down a much more effective ground system. Compared
to the price of copper, particularly large copper , concrete is
relatively cheap. From a practical approach, it'd be beyond many of us
for a number of reasons. Availability and cost of equipment. In
addition, damage to the yard although temporary could be vetoed by a spouse
Interesting idea.. post hole augers are a pretty standard item.
I'll bet there's some literature out there about this.
