EMP And The Modern Computer-Controlled Car, by Oldgeezer

There seem to be a million different opinions on what will happen to computer-controlled cars, trucks, and vehicles of all kinds after an EMP attack. Maybe my experience will help expand your knowledge base. My First-Hand Knowledge I have spent many an hour reading about EMP, watching numerous videos about its effect on civilization, and had some real doubts about some of the claims. While none of us have experienced a true EMP attack, I now have first-hand knowledge of what we may experience when/if an attack occurs. In 2015, a highway patrol car in our state was struck by …




Letter Re: EMP Computer Question

Guys, What laptop would you recommend for storing in an EMP proof environment, to be used after an event to retrieve electronic files such as Survivalblog/Mother Earth News archives? There are so many options, and choosing the wrong one could be frustrating to say the least. I have hard copies of some essential books, but there are just too many helpful things in electronic format to ignore if it would be possible to retrieve. Thanks for all you do! – P.H. HJL Replies: If the device is to be stored in an EMP resistant container, there are no special considerations …




Letter: EMP Proofing a 1988 F250 Diesel

JWR, In the book “How to Survive the End of the World as We Know It” a device for $20 is mentioned. Where can I get it? – H.P. JWR’s Comment: Go to your local Ford dealership’s parts department. Ask them for a spare “glow plug controller” for your truck (model and year.). If they have one on hand, ask them to see it. If they ask an exorbitant price, then look for the same part at you local car and truck wrecking yard.




Top Six Common Questions Concerning An EMP, by Old Bobbert

Maybe you, like many, have questions about an EMP. As a friendly, and hopefully a pleasing feature, this article is being edited as it is being typed so as to be read as though it were a friendly two-person, social conversation. The Sit-Rep Situation That Initiated Research The sit-rep situation would necessarily be two good friends talking about a recent article concerned about a potential EMP situation caused by a strong ego-driven leader of a small Asian nation with an attitude and an ego to match. We will call our two friends Bob and Ray. Actually Bob (Old Bobbert ), …




Letter: EMP Foil Wrap

Good morning, Hugh and James, I’ve posed questions before RE: EMP protection, and now I have one or two more. Survival blog had a recent series of posts about how to EMP-proof steel ammo cans; I found them enlightening. but they sparked some questions. A Faraday Cage The purpose of a Faraday cage is to completely enclose the item one wishes to protect with a conductive material. This will not permit passage of electromagnetic energy of certain wavelengths. The usual approach to Faraday cages is to exclude all wavelengths of electromagnetic energy. Different electronic components may also be susceptible to …




Letter Re: Does EMP Affect Solar Panel Systems?

EMP Solar Panel Good day sir. The talk of EMP has greatly increased recently for many reasons you are well aware of. What would happen to either grid tied or non grid tied solar systems in this instance? What would happen to generators as well? – R.C. HJL’s Comment: Two of our Writing Contest sponsors, Portable Solar LLC and Quantum Harvest, LLC, both specialize in EMP hardened systems. You should check their sites out and also the videos that they have on YouTube. We have several other advertisers that sell Solar equipment and it would be worth your time to …




Letter Re: EMP Protection Measures

Hugh and James: I’m missing something regarding EMP protection measures, and I could use some help. I have researched EMP, how it’s created, and the common frequencies of EMP. I’ve looked into its relative intensity based on creation mode, altitude (in the case of nuclear devices), and the extended effects attributed to conductive networks. I understand what a Faraday cage is and how it works. And I’ve read numerous articles, lots of forum comments, endless opinions, a quantity of engineering documents, and several much learned evaluations on protecting against EMP. The Problem So here’s where I keep running aground: Protecting …




Letter Re: EMP Telltale

Hugh, Whenever the power goes out wherever I am, the first thing I do is see if my battery-operated watch is still working. I suspect one of these times, the screen will be blank or just chaos. – Sid, too near Niagara Falls HJL Comments: As technology advances, the gate sizes grow smaller making such electronics more susceptible, but at the same time manufacturers recognize that they are more susceptible to static electricity as well. As a result, manufacturers almost always include some basic protection in the on-board circuits. Add to that the concept that the amount of energy absorbed …




Letter Re: Using EMP-Hardened HF Ham Radio

Hugh, I strongly recommend against using any Heathkit rig for an emergency radio. There was one solid state Heathkit but it was a rebadged, factory assembled Yaesu. All others were built by an individual, whose attention to detail you most likely have no idea about. They are known in the hobby as “GRIEF kits” for a GOOD reason. They fail – early, and often. They have too many disadvantages for the emergency backup purpose. Besides all the ones mentioned by the original author: They have high (LETHAL) voltages inside. They require 120V AC power. They have no cooling fan on …




Using EMP-Hardened HF Ham Radio to Send/Receive E-Mail During Nationwide Outage- Part 1, by PrepperDoc

There are multiple possible scenarios that may result in a regional an/or national combined loss of Internet connectivity and cell/telephone service, during which you would probably wish to maintain communications to loved ones and others. EMP may destroy routers, cell towers, and power sources; solar coronal mass ejection (CME) may remove power from all communications systems; cyber warfare may have similar outcomes. Travel in some of these circumstances will be difficult, or dangerous to impossible. Ham radio VHF/UHF repeaters may go down, due to power outages or EMP. Direct, point to point simplex VHF Ham radio will still work (even …




Letter Re: Shielding Electronics From EMP

HJL, Another point on electromagnetic pulse (EMP) and Faraday cages is even something simple can be protective. There are 30 Gallon galvanized steel trash cans with lids (made in the USA!) available at my local farm and ranch store for $22. This makes for affordable and easy storage, and you can wrap things in common aluminum foil. Or even something like a steel cabinet or vault, but generally try to avoid gaps or spaces. It doesn’t have to be zero signal, but reduce the field strength enough to prevent damage. Vehicles have some protection for many years. In the early …




Two Letters Re: EMP Effect and Pacemakers

James: While case-by-case circumstances can effect the practicality of many alternatives, there are external pacing and monitoring options. The Zoll Company for example has just released a type of vest, worn similar to a brassiere with a fanny pack (battery pack). This device consistently performs cardiac monitoring and when a shockable rhythm presents itself the device does just that. More archaic methods would involve adhesive defibrillation or subcutaneous pacing patches and a cardiac monitor, while the monitors can be significantly expensive, older models are available at online auction sites. Both the aforementioned devices can be recharged, and more importantly, stored …




Letter: EMP Effect and Pacemakers

Hugh, I have an implanted cardiac device (a pacemaker and defibrillator) and, after reading the letter about possible effects of electromagnetic pulse (EMP) on batteries, became curious as to how an EMP or maybe a strong solar flare could affect my device. I searched SurvivalBlog’s archives and saw that such an event could possibly damage the implanted cardiadefibrillator (ICD). Is there any firm evidence as to what may actually happen to an ICD or similar device in the human body and anything that can be done to counter the effects? It seems it will be a bleak future for the …




Letter Re: EMP Question

Hugh, I’ve asked Matt Bracken this question, and he didn’t know. I’ve read all of your EMP-related data, but none of them answer the question of whether batteries, particularly the small D, C, AAA, AA types need to be shielded to protect them from EMP. All authors make much of electronics in devices but never mention separate stores of batteries or the dangers of batteries stored in electronic devices like radios, sights, et cetera. Your advice would be greatly appreciated. – S.D. Hugh Responds: There is much FUD in the online world (and in books) about EMP. Some of it …




Surviving EMP: Suburban Circle Garden- Part 2, by Northwest Native Elder

Step 3: Buy the best of plants for surviving I have listed the vegetables below that I have planted and that have proven successful for me. Also, I have ordered the following plants from 1-5 with #1 needing the most sun and #5 needing the least sun. They will all benefit from the most sunlight they can get, but tomatoes need full sun and heat. It is a short list but an important one. These are the plants that you, as an inexperienced gardener, will have the best chance at growing, storing, and surviving on. You may have to supplement …
