This reminded me of the family farm. My grandparents used to fill old tires with cement and stick heavy metal poles in the center to use as fence posts in the barnyard. Problem was that even with an old porcelain insulator on one they still could give you quite a shock if you touched one when it was damp out. Electric cow fenders hurt... a lot. (I may have been sorta knocked out once by one on accident...)
Anyway, very cool idea!
