I do find that very interesting indeed.
In my profession, to "save" the guy anchors in guyed communication towers, "sacrificial" devices are placed in the ground next to the guy anchors. This is called a "cathodic protection system". The sacrificial anode pulls the decaying properties to itself and away from the guy anchor.

I know, sounds off the wall, but that is kind of how I relate to what you are saying. So how is it the copper is sacrificed? Is it high amounts of heat?
