Your home microwave is a great faraday cage, as long as you don't turn it in by mistake and nuke what you're saving inside.
Non working microwaves are very cheap (actually so are most working ones) and are a great place to store electronic components.

Q. don't you have to put the cord into the ground to act as ..?? ground wire?? right words?

In my understanding the cage acts like a medium for the charge or pulse to flow around whatever is inside. If the pulse has an electrical charge.. IE lightening or similar then yes grounding would help. If you have a solid metal box with no gaps it acts much like a pelican case would in a wet environment. It keeps the pulse out. So long as what you are protecting doesn't have metal to metal contact with the box it will be fine. I have a 20mm ammo can with the rubber seal removed and replaced with braided steel wool. I also have a 36" battery cable with a clamp on it to attach to a water pipe. Redundant but.. what the heck..LOL.

The same thing I told compatible2012, which he went off on a tangent about.

That Dude is always going off on someone or something, even when they agree with him/her..

Not knowing anything about this subject, I did some internet surfing and came across an interesting posting by somebody on a different website saying the following:

"CME's by themselves will not cause electrical problems with ordinary household technologies. Its not like an EMP. The earth's magnetosphere is your Faraday cage and its darn effective. Long antennas and electronics that come close to the same frequency as the electric discharge that a CME causes when it strikes the magnetosphere are usually the ones that are affected. This could be transmission lines, satellites, HAARP sensors, certain cell trees or microwave stations.

However..... if the magnetosphere suddenly shrinks (like when the magnetic polarity of the earth suddenly shifts or disappears) then you need to be under 2 meters of earth."

This information was from: http://2012forum.com/forum/viewtopic.php?f=40&t=21727

Not being a scientist myself, not sure if there is any truth behind this but hopefully somebody here is up-to-date on this and can shed some light for those folks like myself.

Its not so much the CME as much as the polarity that causes the damage. a northern polarity can do some damage, but it is the southern polarity that can do major damage. Check my article on CME vs. Transformers, its also on Google, (I don’t know who posted it but it wasn’t me). The intensity will determine if it is an inconvenience or an ELE (extinction-level event) (see movie “Knowing”). Also follow the link below to watch a Discovery Channel “Perfect Disaster - Solar Storm” , it a 5 part series that was seen on TV 2010.

Ranger,
the board is set to index so the web crawlers and search engines, call blogs, forums etc looking for material. Yours is linked back to here as far as I know.

There are ways to make hidden, non searchable areas in the forum, the indexing rules must be changed for those sections, password access only etc.
