Re: Lightning - Damage & Detection

Perhaps the best way to deal with potential lightning strikes is to Detect them as they approach...
IF you had a Lightning Detector (also called Strike Finders in aviation - search Goodrich WX950 or StrikeFinder), you could use it to count the strikes within a certain distance.  When it meets your pre-programmed threshold, it could be used to "unplug" stuff, or ground stuff via relays etc.
I had a WX950 in my plane and it worked great!  Gave me lots of heads up and found every strike within 200 miles in calibrated distance and bearing.
See the last link to build your own!  Easy and cheap.

Sounds loosely like the a very long beverage antenna.
