Hank, give it up. surrounding something with copper mesh

wouldn't you think tin foil would work?

Tin foil (actually aluminum foil) is as good of a Faraday shield as anything
until there's enough current to vaporize it. If you're talking lightning
bolts there may or may not be enough current to vaporize it, but its still
far better than nothing.

Lightning is just ESD on steroids. ESD is well known to be able to destroy
unprotected electronic equipment. Effective ESD remedies include bags made
up of plastic bags with lines of graphite-bearing ink or a microscopic
sputtered layer of aluminum on it. In either case the effective conductive
shield makes aluminum foil look very robust, indeed.

Didn't say anything at all about that part of it. Now
tell me, how much tin is in "tinfoil" you could buy today?

There is little or no tin in it, but there is plenty of aluminum. That's why
the box reads "aluminum foil" on the outside. Do much shopping?

Surrounding something with copper mesh does what, without
a path to ground?

An ungrounded conductive box is an effective Faraday shield. The charge is
on the outside and the people inside are kept safe. *Thousands of people
have had their lives saved by ungrounded conductive airplane bodies and
ungrounded conductive automobile bodies when lightening strikes the airplane
or a power line falls on a stalled car.

MY Bad! I said tin foil but that's like saying Q-tip to me. Aluminum
is probably what he used but he called it tin foil too. Us old people
ya know........
