I stumbled onto this! Great find on my part. I’ll be sharing.

Thank you, I really appreicate that. Glad you liked it.

Two books ive read on this topic is "One Second After" by Dr William Forstchen. This is a fictional story about an EMP in the United States with certain estimates of death and chaos from "government" experts. The second is called "Lights out" by Ted Koppel. This is more of a non-fiction, interview style book about the potential grid failure. Both great books. One Second After is based in Black Mountain North Carolina. I cannot drive through that portion of Interstate 40 without thinking of the book and the chaos that would happen if we had an EMP event

I read One Second After, I thought it was an interesting read. While making this episode, I did come across an interview witg Ted Koppel discussing his book. I'll try to add that to my reading list at some point.

Welp. Time to run to the Costco and buy all the toilet paper!

[@PartisanCommsGroup]

Don't forget the frozen pizzas. During Covid I was walking through my local supermarket, and noticed there wasn't a roll of toilet paper or a frozen pizza to be found.

One of the questions that everyone seems to have about an EMP type event: What are the actual effects on electronics? What parts of the electronics go bad? How would we know what would still be usable and what would not? What actual effects would an EMP have on our lives, because what are the effects of things going bad? The physics behind an EMP are something that we can actually apply math to. The data we may have to use could be data from the high altitude A-bomb testing that the US did in the 1950s, which produces the largest EMPs that we currently know of, that could damage electronics on the ground. Many HAM radio frequencies bounce off of the atmosphere to get additional reception range. As it turns out, this same phenomenon happens when a nuclear bomb's EMP bounces off of the atmosphere, if the bomb is detonated at high altitude instead of near the ground. Note that this happens much more during the day, so this type of attack could happen during the day.

All good points. While researching for this episode, I had many of the same questions you raised. There is a lot of good reference material out there, such as previously conducted nuclear tests, etc. However, to your pont, there are still a lot of questions as to what the effect would be on some modern electronics? Some of the things I've read suggest modern electronics would be sensitive to such an event, and other material suggests that it's possible certain electronics may survive. It's an interesting subject.

@@PartisanCommsGroupOne of the experiements I ran during physics class in college (for mechanical engineering) was an experiment exploring the direction and intensity of the magnetic field in a 2-d plane, and how encasing something in a metal loop would affect things. Basically, we made a tray with lines drawn, and had tools both to measure the strength of the magnetic field, as well as the direction of it. When we put a metal loop down (think cookie cutter), the magnetic field inside this loop was completely uniform, as if the magnetic field increased but the lines that normally would have been scaled over the outside were not changed. I think this is kind of how a faraday cage works? So theoretically, if there is a faraday cage, it needs to be able to dissipate as heat any energy from changing magnetic fields without electrically failing? I think? This should mean that the magnetic field inside is uniform, even if fluctuating up and down? This is kind of difficult to understand anyway. The physics behind this are very difficult to wrap your mind around. I would be interested in seeing how these phyrics can be applied in the real world. For instance, can I just line a case with three layers of aluminum foil, then electrically connect that with the ground wire of a home electrical outlet? Having a plastic case lined with foil near an unused plug, housing some radios and basic electronics, would not be difficult or expensive.
