Lightning Protection System
Google lightning protection - look for pictures. You'll see lightning hitting buildings. One site said the Empire State Building gets hit 100 times per year. No damage because of LPS.
Look around - the fire house on Buena Vista and the buildings in LSL, the airport, municipal buildings, skyscrapers, they all have lightning protection systems. Would they do this if it didn't work?
I indtalled one in my house as a relatively cheap form of insurance against a lightning hit. Will I ever know it worked? I hope not, but it's there now.
Oh, one other thought - even an all electric house can be struck by lightning. It may not have the same potential for catastophe as one with flex gas lines in the attic, but it can be damaged nonetheless. Maybe it won't burn down, but a large hole in the roof can't be something you'll enjoy dealing with.
Remember, we live in what some consider to be the lightning capital of the world, just having all electric won't stop the lightning.
