Making a Faraday Cage is actually a lot easier than it looks. In simple terms, a Faraday Cage is simply a metal box, filled with insulating material to protect the contents. What are the contents being protected against? The contents are being protected against a generated high voltage/current electrical charge called an EMP, or Electro-Magnetic Pulse delivered via a nuclear blast. This pulse, while seemingly harmless, can actually fry electrical devices that operate with solid state circuitry, which today includes everything from a kids radio controlled toy car to that jet flying overhead on its way to who knows where.

Everything with any kind of computer chip, diode, capacitor or any other component is susceptible to this danger, and that is why we must take it seriously today. According to the website 33 Minutes, there are over twenty nations with nuclear capabilities, and any one of them could very easily use their technology to attack a foreign nation to disrupt that nations electrical systems. In short, one big bang could push a nation back into the pre electric age, or the 1800’s.

Delivering such a catastrophic blow would be difficult because of the altitude needed to achieve for this damage over nationwide regions, but it could be done. And really, the attacker wouldn’t necessarily need to cover such a broad area to inflict serious damages. Generally, this is because the EMP generated by a detonated warhead far above the earth would only be effective within a line of sight, and would need to be close enough that the charge would not dissipate prior to contacting any electrical utilities or devices. For instance, if a hostile nation were to launch a missile from a freighter a hundred miles off the coast of California, and detonate it at an altitude of 200 miles, it would not directly affect the entire US.

Such a blast would, however, decimate the entirety of the west coast, and the damage to the infrastructure would extend inland possibly as far as the Mississippi River. Commercial power would cease to exist. The ports and air traffic would come to a cataclysmic standstill. No freight or people would be able to move. Shipments of goods would sit right where they were at the time of attack as there would be no way to unload them from incoming freighters, and there would be no way to run the tractors that would haul the containers. And that’s just for starters.

The resulting domino like failure of the victim nations infrastructure would effectively cripple that nation, and it may take years to recover from the blow. We seem to forget at times that all things are connected in this world, and especially more so now that we have come to rely upon outsiders via the internet and the electrical distribution grids and telecommunications. therefore, it is imperative that we provide for a way to protect our valuable equipment from this threat. There are few ways to accomplish this, however, without expending a government sized budget upon the process. There are ways to build rooms and entire buildings with such a threat in mind, but who amongst us possesses that kind of free capitol?

The answer for most of us is to build a simple metal box to act as a shield against EMPs. If you have some metal working skills, you can make your own box, but any solid metal box will do the same trick. The main thing you want to remember is that the surfaces where the lid and the box itself meet need to be 100% in contact with each other, with no spaces for electrical current to leak through. Early tests were made with mesh screening that were successful, and adequate protection from a light charge could be made from such a box, but a solid metal box, such as an ammo can, tool box, or storage tins would be far better. And these types of boxes would provide better physical protection as well.

While it is difficult to keep your everyday gadgets and components in such a box due to the inconvenience, these boxes can be made to hold backup gadgetry and components as well. You can even use a steel garbage can, provided it has no holes or rust spots to weaken the walls or bottom of the can. If you do use a garbage can, remember that the lids usually don’t close that tight. To correct that situation you’ll need to place a flexible metal collar around the top of the can before placing the lid onto it. Steel window screening will do the job just fine. If the surfaces of the container you will be using are painted, take some sandpaper and remove the paint to assure a metal to metal contact all the way around the lid.

There are some preparations we can make that will make surviving such a disaster a little easier:
Obtain a supply of spare parts for radios and automobile computerized ignitions. Everybody has an automobile, and all newer cars contain tones of solid state devices. If you can afford it, pick up some of the bare necessity parts that you can replace in your car to get it running again. The same goes for any radios that you may have, such as a short wave or multi band radio receiver and transmitters, etc.

Always keep electronic components disconnected from their power source when not in use. The EMP will use wiring as an antenna and travel down those wires into your equipment.
Keep an inexpensive CB and/or short wave radio and other sensitive equipment in a faraday cage when not in use. Protect your generators from an EMP by placing several layers of chicken wire fencing under and around the generator. Keep all cords inside the wire cage.

The fact that we may well be attacked in this manner in the relatively near future suggests many things that most people would rather not hear about, but these things must be addressed. As our reputation and power wanes around the world we will become more and more vulnerable to harm. Only by keeping to our preparedness plans will we be able to survive the coming times. Plan and practice what you learn here and from other information sources. It also my help to start getting involved in local politics, if you haven’t already. Get your local politicians to see the sense of a community disaster plan. Get them to see the value of becoming prepared, and get them to see that emergency preparedness is a vital element of a communities survival prospects.
