Interesting. I've seen utility companies in my area install new wood poles 
that had a coil of heavy copper wire stapled to the bottom of the pole 
before it was installed in the hole. The wire then ran up the pole a bit so 
that it was above ground level when the pole was installed. Don't know what, 
or how it was connected after that.

Yup.

Although I can't find it anymore, I swear I saw a diagram in a code book
that called for the 20 feet of copper wire to have a few wraps around
the rebar in the trench before the pour.  Probably that was just to make
sure that the wire didn't get displaced (pushed to the bottom of the
trench) during the pour, but just in case I added some bronze pipe
clamps along the run to affix the wire to the rebar.
