Do You Believe in EMPs?

“Do you believe in EMPs?” questioned an older woman in one of my classes this weekend. Until she asked me this question, I suppose I never considered whether or not an EMP was to be “believed in” or not. None of my readers will be shocked to hear that I responded “Of course I believe in EMPs.” My follow-up question to her should have been “What’s not to believe?”

In a previous article I cover the logistics of an Electromagnetic Pulse. But I want to remind you that an EMP is the most economical approach for any enemy country to use against our nation. The EMP technology does exist in the Soviet Union, China, and North Korea. Because it exists in these other nations, that also means it could easily be “for sale” to even more ardent “haters” of the U.S. such as Venezuela or any number of Muslim enemies. Given that our nation is so reliant on electricity for all of the our money circulation, shipments of food and medications, water treatment, and healthcare, an EMP would be the perfect way to debilitate our nation—without the mess and expense that would be necessary with other forms of attack.

If an EMP is used on our nation, it would only take 3 EMP launches above the atmosphere to crumble our entire nation. Parts of Canada and Mexico would likely be affected as well. With an EMP strike there would be no need for an enemy to plan and prepare with all of the expense of shipping large armies and weapons over here. Besides, wouldn’t our detection systems see them coming from a long ways off? Additionally, there would be no need for the enemy army to bear the expense of caring for the sick and wounded. They would simply allow time to take care of that “problem” for them instead. Within 4 to 6 months the weak will have all died from a lack of medical care. (Just think about how many of Americans are dependent on gadgets and technology to keep us alive.) Afterwards, the enemy attacker could easily sweep in and no amount of communication would be available to provide any warnings. They would then have easy access to all of our nations assets along with a strong workforce. Easy peasy, right?

It is due to this awareness that I strongly suggest that if you are going to prepare and protect any electronic devices from the effect of an EMP (via a Faraday Cage) that you focus primarily on communication devices first and foremost. Communication and our hardened resolve will be critical in surviving any enemy attack. Communication enables planning, protection, and strategy. The lack thereof only enables a “sitting duck” scenario. I hear too often of individuals thinking that they will need to protect their cell phones, internet access, and televisions. Excuse me while I laugh at such ignorance and naïveté. If you’re one of those people, think about this for a second. Cell phones, televisions, and computers are only viable communication aids when the originating core network is functional.

While he was a teenager in a small town in the middle of nowhere, Utah, my father-in-law operated a radio station from his bedroom closet. (He actually had a few listeners and he went on to be a great voice of radio many years later.) As I recall this story I’m reminded that having the ability to broadcast a radio signal doesn’t take much effort, equipment or expertise. So I would recommend that you put such skills in your Mental Preparedness category and get it checked off your list. Being able to hear broadcasts of the truth to counteract the broadcasts of brainwashing was critical to the survivors of every major war fought throughout the last 70 years of history. It’s something you can plan and prepare for now.

Now, take heart and fear not. To be clear, based on my scriptural knowledge and belief I do not believe that another kingdom or principality will ever hold this nation physically. But I DO believe that there will be many who try to conquer the U.S. on a more vicious level and an EMP would be the most likely tool. Whether or not an enemy is able to fully execute their plan, they would still be able to do an unfathomable amount of damage in their attempts—such as with an EMP. But the same scriptures which give us this ultimate peaceful assurance also tell us of our “chariots and horses” being “cut down.” (Just imagine an ancient prophet trying to describe our automobiles and other transportation methods hundreds and hundreds of years ago. I’m sure that horses and chariots were about the best they could come up with.) On that note, :) tomorrow I’ll address a bit more of the most likely time an EMP would be launched. Stay tuned.

EMP 101: Part IV—Faraday Cages

Faraday Cages

By Kellene Bishop

We’ve established that an EMP incident will fry all electronics.  This occurs whether or not they are plugged in or turned on. This also affects automobiles, batteries, computers, medical equipment, etc.  Needless to say, in such an instance, life as we know it will change dramatically.   Even more distressing is the fact that the strike of an EMP is not likely to give any warning. You don’t see it. You don’t feel it. You are simply left with the sudden consequences and whatever preparedness you have on hand.  So, other than your preparedness supplies, your new best friend may be a Faraday cage. In fact, with the knowledge of the protection that a Faraday cage can provide you, you may be able to enjoy nearly as comfortable a lifestyle as you did prior to any electromagnetic pulse.

While being mentally prepared to live in the Stone Age may be helpful, it’s not necessary. Aren’t you glad?

First of all, allow me to dispel some myths about Faraday cages—and boy, howdy, there are a LOT of them.

  • Whether or not your electronics are plugged in, how long of an antenna you’ve got on something, what voltage it is, or whether or not they operate with batteries—all non-protected electronics will be affected by an EMP. 
  • Batteries will be affected, usually in the form of “shorting” as well.
  • Electronic phone systems will also be damaged. 
  • Surge protectors are useless in the event of an EMP exposure. 
  • Just because your car has rubber tires, it will not be impervious to the effects of an EMP.  Rubber containers are insufficient protection against an EMP.
  • And oh yeah—yes, your Faraday cages DO need to be grounded.  If it’s NOT grounded, then the Faraday cage merely becomes a reflector or an amplifier.
  • Yes, a microwave can act as a Faraday cage, but why in the world would you want to use it for that?  That’s just silly when you can make one simply.
  • Faraday cages do not have to be solid, thus the name “cage” instead of the oft misused term—“box.”  In fact, many of them that you can build yourself or will see on the internet will resemble a bird cage or a very finely meshed chicken coop wire.

  • Also, contrary to what you may see on the internet, a sheet of foil on a box will not protect you.  It’s not thick enough to withstand the pulse. However, you CAN protect your items if they are buried a couple of feet underground in every direction (up and sideways.)
  • Last, but not least, a car is NOT a Faraday cage sufficient to withstand an EMP incident. It has some similar components, yes.  Most cars made today consist of fiberglass and disjointed parts, not a continuous metal material.  In addition to that, they are on tires.  Tires on a car do NOT serve as grounding.  Folks are simply getting an EMP strike confused with a lightening strike.  Now, IF you had an old fashioned car that was made of metal, that had its tires removed, that was also attached to an Iron or copper pole and that was ALSO on dirt—not  gravel—then  yes, you may have a car that doubles as a Faraday cage. (Kind of like the old clunker my dad has out in his “back forty.”  
  • The cages do not have to be solid, but they do have to be constructed continuously without gaps between the protective material.

There. Now that we’ve discredited 90% of the internet information out there, let’s continue.

Faraday cages are named after Michael Faraday who invented them in 1836. They block out external electrostatic fields and electromagnetic radiation.  One mistake many people make when it comes to an EMP is to compare it to a lighting bolt.  The effects of an EMP and a direct lightening bolt are very similar, but they are not at all similar in terms of their visibility, and affect on the body. An EMP is more like a radio wave, not a visible bolt of light or electric current.   

It’s the substrate layers of the diodes and transistors that make them susceptible to a magnetic pulse attack. Electronics are made up of diodes and transistors and substrate layers. A computer, car, television, and cell phones are made up of tons of transistors. When hit with a powerful magnetic pulse, the substrate layers are destroyed. However, early 1960’s and before electronics did not use substrate layers. They used vacuum tubes.  This is why older electronics are less susceptible to damage. This is why a human or animal body will not be affected.  Yes, our bodies consist of an electric volt. But understand there’s a difference between electricity and electronics. 

I just want to reiterate this again.  It’s important that any Faraday cage that you plan to use is grounded.  It has to be grounded in order to disperse the energy. 

What you should know though is that a Faraday cage is not fool proof.  The higher the frequency of the magnetic pulse, the faster it is. This is what causes the burn out.  The cages must be grounded, continuously connecting, and the openings of them cannot be too large. Chicken coop wire would work, but only if you double or even triple layered it as the opening are too large. For a reference of opening size, look at the front of your microwave door.  It’s a small mesh.  Just a like a snake can slither its way through the right sized hole, so can an electronic wave.

You can have an instant Faraday cage with a galvanized trash can or a large stock pot like they use in restaurants. (Be sure to clamp the lid down. Remember—continuous connection is key. Since Faraday cages are not fool proof, depending on the strength of the pulse, I would recommend burying such containers 2 feet under the ground, storing survival electrical and battery items. (Including batteries). 

An easy way to make a Faraday cage would be to acquire some 2 x 4 brass mesh sheets. (Mythbusters on the Discovery Channel did a couple of experiments using this successfully.)  Make a box frame with the 2 x 4′s and staple the brass mesh to the outside. Create a securely attached/connected access entry within the frame. Solder a ground wire to one of the corners and ground the cage.  Scrap metal and mesh wires can easily be obtained in junk yards, on E-bay, the clay modeling section of a craft store, or at your local hardware or  “farm and feed” store.  The important aspect of this to remember though is that mesh or sheet metal only shields magnetic fields if the frequency is up in the RF range. To properly stop the wave, you need some iron, steel, or some slabs of thick copper.  Most electronics are useful in the VHF/UHF/SHF range today and will need more substantial protection.  Remember when you’re browsing the internet.  Protecting against sparks is not the same as protecting against a strong magnetic pulse.  

You can make your “cage” as small or as large as you’d like.  It wouldn’t be out of the question to continuously line a basement storage room or hole in the ground with copper mesh wire and a grounding rod.

Bottom line, with an appropriately constructed Faraday cage, you can likely protect that which is inside from the electromagnetic attack of an EMP incident or solar flare, thus preserving the function of all that is contained therein.   Here is a very simple example of how Faraday cages work.  (DO NOT try this at home, please)

Note that the Peeps are put into a mesh bowl and covered with a mesh cover. They are then put in the microwave.  The one Peep that wasn’t put in the microwave met his untimely death, while the others were still intact.

For a little bit of a science lesson on the workings of a Faraday cage, check out this YouTube link. The science professor is EXCELLENT.  Note though that he does say that a car is a Faraday cage, however, I want to reiterate that it is NOT sufficient to extinguish the effects of an EMP attack.

Be selective in what you protect. It makes no sense to protect a cell phone, for example, as the cell towers will be useless.  If it were me, I would protect radios, communication devices (such as a HAM radio), batteries and all of their respective tools, thumb drives loaded with all of my vital information, and a laptop.  Keep in mind that a Faraday cage should be your LAST concern in terms of protecting every electronic that you enjoy presently.  It’s not like if you preserve your television you’re going to have any “juice” to plug it into.  Don’t focus on a Faraday cage and its time, effort, and expense at the risk of neglecting food, water, and medical supplies. It would be better for you to read up on solar power, wind and steam energy instead.

EMP 101: Part II—The Aftermath

The Aftermath

By Kellene Bishop

Yesterday we discussed the reality of an EMP attack on the U.S. and today we will bring the aftermath of an EMP attack a bit closer so that we can mentally go through the various ramifications.  If you mentally prepare, even little by little, you will be significantly better off.

The Aftermath Reality #1: Since an EMP essentially fries anything electric, this means most automobiles post-1970 will be useless.  This may explain why my husband’s dream car as of late is a 1967 Ford Bronco. :) As early as 1970, key components of automobiles were made with electrical parts.  You’re well aware that some models today brag about being completely electrical.  This will be problem with an EMP.  If you’re driving your beautiful Cooper car when an EMP strikes, you won’t feel the road rattle.  You won’t hear a noise.  Your automobile will simply stop dead in its tracks.  Be prepared mentally for alternative transportation.  For me that’s “hoofing it” so I have a couple pairs of good shoes in storage, and made sure that my bikes have several tire repair kits to go with them.  You may also want to consider having a “li’l red wagon” or something that you can easily push and pull with supplies or your passengers therein.  This is not to say that you will have to flee where you are when an EMP hits, but as the aftermath becomes a way of life, you will have to travel at some point even if it’s just a mile or so.  Personally, I will want to be able to travel so that I can check on other individuals and deliver any aid I may be able to.

The Aftermath Reality #2: The most vital services that will be destroyed in an EMP attack are communications.  Telephones, radio, walkie-talkies, etc.  Can you imagine what life will be like in the aftermath without these luxuries?  And to think we mock individuals who don’t have texting abilities nowadays. :) This is yet another reason why you will want to make sure your walking shoes or your bike are ready for use—delivering messages.  

While your challenge will be wide scale, without proper communication you’ll feel like you’re on you very own little planet.  One of the recommendations I make to prepare for the aftermath is to take the time to get your HAM radio license, appropriate equipment, and THEN be sure that it’s kept out of range of an EMP strike.  This can be accomplished in different ways, but the most popular is a Faraday cage.

You can easily create a Faraday cage which will protect most electronics from an EMP attack.  We’ll talk more about Faraday cages later in this series.  (Sorry, I haven’t found a contractor yet who can do this to my whole house.)  You can actually obtain a Faraday cage from a business that’s going under that has been using one for their server room.  I’ve even found decent sized Faraday cages on E-bay.  Then again you can also use materials of your own for such storage with aluminum foil, mesh copper or brass sheeting, a cheap “space blanket” made of Mylar, or even an oversized stock pot!  There are Faraday blankets available as well.

The Aftermath Reality #3: The banking industry will be destroyed with one pulse.  No ATMs, folks.  You will be unable to buy any goods without cash.  (We’ll see how long human nature allows such civil transactions to take place before burglary and looting commences.)  You will be unable to fill your car with gasoline, even if it is an older model.  Gas pumps are operated electronically nowadays.  Your home security system will be useless.  You won’t be able to rely on the television and video games to entertain your children.  And you’ll have to be sure to have an alternative way to cook your meals—as well as the knowledge necessary to cook in such a manner.  There will be no refrigeration.  So either keep your freezer and refrigerator closed for as long as possible, or start canning meats and such and eating the foods in the freezer first.

The Aftermath Reality #4: Lastly, consider the medical implications of an EMP attack.  Obtaining medications that we are accustomed to using will be virtually impossible.  Those individuals who rely on medical technology to survive in their homes will be at the highest risk in the aftermath of an EMP attack.  Unlike our food supply which relies on a three day delivery cycle, our medical supplies largely rely on a one day delivery cycle.  So what can you do to prepare?  First make sure you have as many medical supplies on hand that you can obtain such as pain relievers, cough and cold remedies, anti-bacterial creams, hydrogen peroxide, rubbing alcohol, cotton balls, heat packs, essential oils, and your own medications.  (Just so you know, since I use coupons, I get the majority of these items really cheap or for free!)

Next, do all you can do now to get as healthy as possible without medication.  When I started out this year I had a stark moment of realization.  I looked at my nightstand and saw 7 prescription bottles.  I knew that such reliance would hinder me dramatically if we were to encounter a true emergency, so I made the goal to get healthy so that I could eliminate all of them.  It’s been 6 months and I’ve eliminated all but one of them by focusing on the use of high quality nutritional products.  I may not be able to store a year’s worth of medications properly, but I CAN store a year’s worth of nutritional products that help me replace the chemical alternatives. 

To recap, prepare your mind and your body for the aftermath of an EMP attack, and you won’t end up being the star of your own Armageddon story.
