40' shipping containers seem to be the rage.  Apparently you can pick one up for $2500.  Sure enough, I saw some on ebay for $2500-$3000.  One guy on last night's show was planning on burying 3 containers for an underground bunker and to protect electrical assets from EMP.  Would make a hell of a good root cellar, too, I'd imagine.

How far underground do you have to go?  If grounded will the container act as a Faraday Cage?

[charlesoakwood]

If so, you could install a grounding system and sell 'em on ebay for 10.

The containers are all welded, andif buried should have a find ground contact.  Yes they should work as a faraday cage.

Cool.  Might have to look into this.

If burying is the plan, the roof will need reinforcing.  They are stackable because the weight on top rests on the corners, not on the top itself.

 Very true. But thankfully the width isn't a big deal and one center support in the form of wood beams or metal I beam will do nicely.Depending on how much weight were talking about in other words how deep you're planning on going.And don't forget to waterproof it.

How does a biogas plant work?





  How about this?Just food for thought.

You don't need a separate ground...

Faraday Cage: Garbage Can, Really?

How does a biogas plant work? (The video's owner prevents external embedding)

Obama keeps it up and this will be viable.

I like that Faraday cage.       
The F150, it's got the ECM and what other chips are necessary
after an EMP?  Or is it even worth the thought?

[Alphabet Soup]

I wish I knew.

My '37 will still run because all I have to do is replace the condenser - it has no electronics

 Will pulling the battery cables help protect it?

I don't believe that batteries are susceptible to EMP. Transistors and integrated circuits are. I wouldn't care to test that theory however. My '37 has a battery disconnect switch (poorman anti-theft) and I turn it on when I want to go for a ride.

 The reason I ask is because I'm not much on electronics but I would think that if no power is going in all they are is a nothing.

Container support - I would think treated wood for supports above assisted by 4x4 pilings on the side would work, and a good quality tarp for waterproofing would do the trick.

Garbage can Faraday cage - Interesting, simple, hate to have to find out the hard way if it works against EMP, but what the heck, better than nothing.

Biogas plant - OK this one looks beyond my ability.

Electronics - Don't certain components (capacitors etc) retain a small charge, and if so, wouldn't they be subject to potential damage if hit?

[Alphabet Soup]

Apparently existing current flow in an electronic component makes no difference pro or con to the susceptibility to EMP. There are reports of products containing electronic circuitry sitting on the shelf in their original packaging being fried by the induced voltage spikes. I'm still looking around but here is an interesting article on EMP: http://standeyo.com/News_Files/NBC/EMP.protection.html

Huh, then according to that link the garbage can should work for sensitive equipment.  Now all I need is a reaaly big garbage can to drive my SUV into.  Oh, the cargo container!

[charlesoakwood]

The magnetic waves can run along telephone wires or fences and they love car antennas.  If there's a crack
hole, vent, anything like that they'll run through the whole device.

Roughly put, IRRC, the EMP only lasts a millisecond that's why it doesn't bother analogue electronics
they are course and insensitive just like us.  That's right we could be standing next to our electronic car
an EMP with a zillion volts occur and it would be so short a time span that we would not feel it or
be harmed but the electronic in that car would melt.

Taurus gets zapped by EMP

[Libertas]

Poor Taurus.  RIP

I saw some of the metal trash cans at Fleet Farm this morning.  I took the day off as my SUV was in for work, the rental is a Mazda 3 so no room for trash cans!  But I'll pick up a few on the way to the lake next weekend.
