I am not worried about terrorism and power lines (how many poles lost to terrorists = 0)
I am worried about storm/weather damage = thousands of poles knocked down each year
millions lost to economic impact of power outages each year
let us address the real danger before the imaginary |
No I agree that terrorists dont attack power lines, but they are not currently good targets. An anarchist wanting to disrupt society could do so if he knocked out the infrastructure that is in the solar plan for America or whatever it was called. It will never happen because we will never allow our energy security to be dependent on a bunch of select power lines.

I know that there are techniques to find breaks without digging up the line, but you still have to walk the length with your instrumentation dont you?
