High-Voltage Fences For Zapping Would-Be Copper Thieves
coondoggie writes "It may be a gimmick or the ultimate answer, but a California city this week okay-ed a draft ordinance that would let businesses install 7,000-volt electric fences to protect sites from rampant copper thieves. As reported by the Sacramento CBS station, the reaction from one business owner to the ordinance says it all: 'It'll be a little fun to watch one of these guys get electrocuted holding my fence trying to rob me.'"
They tested pissing on an electric subway rail and that failed. They then tried the electric fence and it did work. Perhaps you should have watch the WHOLE episode before commenting here.
The busted the third rail, but found electric fence plausible. http://en.wikipedia.org/wiki/MythBusters_(2004_season)#Peeing_on_the_Third_Rail
