The power supply will happily arc for days. I had a downed power line in my backyard... slowly sawing (arcing) its way through a large tree. When I called the utility... they said

Harry Bissell <resume lurk> I've never heard of anything close to this happening here. 'Course, I have to admit that most powerlines these days are buried - and high-tension lines are well-isolated from trees. I'll have to ask a friend of mine with high-tension line experience.
I wonder if a powerline swinging in the breeze can be modelled as a kicked pendulum?
