Faraday cage won't buy you anything, because the lightning's EMP is
magnetic and goes right thru it. Better to use fiber optics on as many
of the incoming signal lines as possible.
Why a generator? Why not the batteries in a UPS??
Speaking of insurance. If you read the fine print on those surge
suppressors, you'll see that you will have a harder time collecting
their insurance than you will winning the lottery. :-(

PUNCTUATION - Apostrophe
Incorrect uses: (i) the apostrophe must not be used with a plural
where there is no possessive sense, as in ~tea's are served here~;
(ii) there is no such word as ~her's, our's, their's, your's~.
Confusions: it's = it is or it has (not 'belonging to it'); correct
uses are ~it's here~ (= it is here); ~it's gone~ (= it has gone);
but ~the dog wagged its tail~ (no apostrophe).
