Sure... conductors are conductors.. Al isn't as good as copper, but I
suspect that the losses from this would be negligible.

Probably not chicken wire (which is what I use as a ground plane), but more
like copper flashing. A thin sheet of copper in various widths (typically 4
inches to 12 inches). It is used in roofing for "valleys" and around
protrusions through the roof to prevent leaks. Why copper? For some uses,
it looks cool (tarnishes green, etc. looks old, which is a selling point
here in So Cal, where old is 50 years). More to the point, it is soft and
malleable, so it can conform to odd shapes, and it is solderable for

By all means ground to your well... can't get much better than an iron pipe
(full of water, no less) running down to the water table. (Unless your
well was cased with copper or silver).

Mostly not working...
Blowing up beyond all repair is when you get frustrated because it isn't
making sparks and kick it over.
