The reality of protecting all electronic equipment against EMP from a nuclear explosion over our shores is becoming imminent. We now live in perilous times.

The information to follow on building "Faraday cages" is timely indeed. A single atmospheric nuclear detonation releases enough electromagnetic pulse (EMP) to equal 100,000 volts per square centimeter on the ground. A single detonation 200 to 400 miles over the center of the continental United States would fry every unprotected computer chip from coast to coast, and from the middle of Canada to the middle of Mexico. And we are now into Solar Cycle 23, with solar flares common and expected to continue until the first of next year. CME's are capable of extreme damage to modern computerized equipment! Sure, we have our windup BayGen radio's and spare lap top computers, but unless electronic equipment is protected from an electromagnetic pulse, they will be fried!

When Einstein and the others first refined and purified uranium, they took time off and studied its properties. That is when they discovered the "rays" that were harmful, as well as the phase transformations. In the course of their work, one of the scientists discovered that simply covering an object with a grounded copper mesh would stop virtually all electromagnetic radiation, whether proton or neutron. Obviously, they had to protect their monitoring equipment! Thus was born the "Faraday cage."

The copper mesh, like 1 inch chicken wire, worked well in large uses, like covering buildings, and it is still in use today: FEMA headquarters buildings are dome-shaped earth-bermed structures, and under the earth is a copper mesh that extends out from the base and is secured by grounding rods.

As an Electro Magnetic Pulse (EMP) travels to earth, whether from a Coronal Mass Ejection (CME) or a nuclear detonation in the atmosphere, it hits and runs along electrical power lines as well, building up voltage and amperage, which is what happened during the last solar storm a dozen years ago, blowing out transformers and leaving 6 million people in eastern Canada without power for weeks.

To prevent that problem, if you have a hard-wired generator, the wiring from the generator to the house should run in conduit that is grounded. The generator itself can have the frame grounded for added insurance, but that ground wire MUST be insulated and run to a different ground rod well away from the ground rod for building and conduit!

With radio's and smaller appliances, a Faraday cage can be built by using two cardboard boxes: one should fit tightly inside the other, and the item to be covered should itself fit reasonably well inside the smaller box. That is about the most work involved--finding the right size boxes! The outer box is then covered with aluminum foil or Mylar, as from a cheap "space blanket." A grounding wire is then taped to the foil. I then cover the foil with black 6 mil plastic, taped securely in place, to protect the foil from ripping. At the end of the ground wire I attach a cheap small alligator clip from Radio Shack. The item to be protected is placed inside the inner box, which acts as insulation from the outer box, and any EMP hitting the foil and is bled away by the ground wire.

Some medium sized electrical equipment can also easily fit into boxes covered with foil for EMP protection. My laptop computer, for example, fits easily into a Faraday box made from a box that held reams of paper: the entire lid is removable, allowing easy access to the laptop in its case, but is safely stored when not in use.

For larger items which cannot be boxed, such as living room TV sets, etc, I tape a Mylar space blanket to a piece of 6 mil black plastic sheet, using double-sticky tape every foot or so to make sure the Mylar stays in place (it is slippery). I leave a 2 inch edge of black plastic showing all around the space blanket, and while taping down the edges I put on a short lead of ground wire. When it appears that EMP or CME's are on the way, the blanket can be draped over the appliance, the alligator clip attached to a small, unobtrusive ground wire behind the cabinet, and any electromagnetic radiation will be diverted to the ground wire. Very cheap, simple, and once done, items can be "draped" for protection very quickly indeed. And the plastic blankets fold up neatly for storage, ready for use when needed.

The time to build Faraday cages or blankets is NOW, as when they are actually needed it will be far too late. Each box should be labeled on the ends and the top for the exact appliance they were built for, to eliminate any confusion when they must be protected in a hurry. Any electrical appliances not in use should be stored in the Faraday cage, where they will be kept clean, neat, in a known location, and protected against any sudden EMP surge.

Congressional Testimony
"...the de facto national policy of nakedness to all of our potentially EMP-armed enemies takes on ever more the character of national scale masochism. It is perverse, irrational, and assuredly not necessary or foreordained."- Dr. Lowell Wood, Lawrence Livermore Labs
What is EMP? According to the Institute for Telecommunications Sciences, Electromagnetic Pulse is:
"1. The electromagnetic radiation from a nuclear explosion caused by Compton-recoil electrons and photoelectrons from photons scattered in the materials of the nuclear device or in a surrounding medium. The resulting electric and magnetic fields may couple with electrical/electronic systems to produce damaging current and voltage surges. May also be caused by non-nuclear means;
2. A broadband, high-intensity, short-duration burst of electromagnetic energy. Note: In the case of a nuclear detonation, the electromagnetic pulse consists of a continuous frequency spectrum. Most of the energy is distributed throughout the lower frequencies between 3 Hz and 30 kHz."
In plain language, it is an electromagnetic "shock wave" that is released from nuclear detonations that can seriously damage any electrical components in its path. EMP can travel either through air or through conductive pathways such as electrical or phone lines. It can affect electronic equipment regardless of whether the equipment is switched on or off.
The goal of this site is to help you protect your communications and computing gear from EMP, as well as provide an understanding of the threats to and vulnerabilities of our electronics-based society.

Letter from LDL.net Reader - Preparation and Outlook

We have lost some members of our group because of their love of this World system. Yet several remain steadfast and determined to leave all behind to follow the Ruach Ha Kodesh wherever He leads.

We have been busy selling property and possessions, and reducing our worldly obligations. Father has been teaching us for the past few months about several necessary life skills, growing organic crops, building sandbag houses, Solar cooking and electric, wind power, distilling water and fuel for heating, cooking, lighting and transportation. Our desire is to live without the worlds services as much as possible so that we are not dependent upon them, but rather on our Heavenly Fathers provision and blessings.

We had plans of starting a community in Mexico, but our hearts long for His promised land. Since several of our members are from Hispanic decent we have our sights on the Negev, especially in the light of Obadiah 20 and the terrain, climate and environment is very much like Yuma. Father's will be done. We will be happy, thrilled and ecstatic when we find someplace to put our roots down.

When people ask, "Do you want to go to Israel?" I often respond by saying, "Not if I have to leave." We are not going as tourists, vacationers or sightseers. We are going with one way tickets. We realize that actually living in Israel is perhaps not possible, but living anywhere nearby Aqaba, Jordon may be the closest we can be at this time. But we do want to be wise and count the cost.

Messiah said, "Whoever does not carry his own cross and come after Me cannot be My disciple. For which one of you, when he wants to build a tower, does not first sit down and calculate the cost to see if he has enough to complete it? Otherwise, when he has laid a foundation and is not able to finish, all who observe it begin to ridicule him, saying, 'This man began to build and was not able to finish.' Luke 14:27-30

We are attempting to make some contacts in the region and would appreciate any assistance you can offer. It would be helpful to be in contact with other believers who are self-sufficient, organic farmers who would like a small group to be a blessing to. We have taken your advice and have begun to study the modern countries of Israel and Jordon. If you would put us in contact with the Messianic community in the area of Jordan and /or Israel we would appreciate it very much.
I have a question regarding your references of Ezekiel 38-39. Are you of the understanding that the incident concerning Gog and Magog happens at this time and not at the end of the thousand years? Revelation 20:7, 8 When the thousand years are completed, Satan will be released from his prison, and will come out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together for the war; the number of them is like the sand of the seashore.

Many blessings to you and all those who help and bless you in your affairs.

Yuma, Arizona

Put to the Test!

I'm going to take this opportunity to say to our readers that Yedidah does not host this web site or http://www.laydownlife.net/. She is a personal friend of mine in which I find her writings informative and inspired.

I have received several emails concerning the accuracy and validity of her information. And others just simply disagreeing with her beliefs. On the other hand, I have received many more letters thanking her for her writings and praising the Father for inspiring her to write.

We should always put every matter posed to the test. It is healthy spiritually to always question what we read, listen to and receive. We should never receive anything without a second witness and having not matched it up to the Father's word.

It is never healthy to rebuke someone in anger or for the sake of correcting someone when we, ourselves, are in the wrong spirit. It is also unhealthy to just simply receive anyone's writings as factual and thinking that it is of the Father. Again, put to the test and wait for the Father's answer to speak to you.

Please watch out for those who have a "controlling" spirit. We all need to be personally responsible for ourselves. Clues to someone possibly having a controlling spirit are those who:

1. Say they only want to protect the flock.
2. Tries to speak for the flock.
3. Rebukes another in anger.
4. Has difficulty in showing forgiveness.
5. Lacks humility.
6. Becomes protective of a flock in an unhealthy manner.
7. I hate to say this, but one who receives tithes and offerings is often suspect to protecting that income and not looking to the Father to provide.
8. One who generally does not administer Mt. 18:15 in going to a brother.
9. One who has difficulty in allowing the flock make decisions for itself, rather than the individual making decisions for the flock.
10. One who proves himself unworthy of not leaving the 99 to go after the lost sheep.

If you have any comments or recommendations, please share.

Shalom

Blog for LayDownLife.net

LDL.net has made the decision to add this blog to the website for the sake of sharing discussion and questions. We're very adamant about the gift we're given among believers in which iron to sharpens iron.

I will be adding letters from the past in which questions have been asked. We have had many ask just who we are and what we believe. And although that is a valid question, we should always be concerned about personal responsibility and not be swayed into believing something that our Father does not put upon us himself.
