surge protector/ power strip, heres a link for ya, but thy can be found at any retailer, link
Well lightning damage is usually caused by static electricity in the air. I myself happen to use a surge protector and my computer was still damaged beyond repair in a nearby lightning storm. Also if the mains happens to experience a direct lightning strike, a surge protector will most likely explode, along with several other mains powered appliences, including your computer, but don't worry about this as it is unusual.
-damage by static electricity? you mean EMI? your going to have to explain more. because i doubt thats making any sence.
-appliences or anythin wont actualy explode. nothing will proly happen except if there damaged thy wont turn on.
-what are u talking about the mains? if the main power lines outside the house get hit, thats not any different then lightning entering the circuit from anyother way. If at all id imajine that would be better, because the main lines prolly have better protection gainst lightning then any other circuit.
-if the circuit breaker doesnt stop it, i dont see why a surge protector wouldnt do anything but help.
-id also imagine that if the lightning hits a line, its not heading strait for your computer or any other applience. its heading directly for ground, but the power spike in the line from it getting hit is what damages some appliences.
