Hello Monkeys. EMPs are one of those prepper topics that has a lot of misinformation and fear mongering. So we dug in to learn about the science, threat profiles, how a pulse would actually affect things, and if there's anything you can practically do to prepare. We spent 95 hours on research and expert interviews, including with leaders who've recently testified before Congress and whose work is part of FEMA's (and the DOE's, DOD's, etc.) risk modeling. What we learned: Prepper guide to EMP attacks The primary researchers are around if you have any questions or feedback? Some highlights: Nukes and solar events are the culprits. Sci-fi EMP ray guns aren't really a thing. Only major nations have the ability to get a nuke-based EMP high enough over the country to do meaningful damage (plus then we're in nuclear war anyway). There are two forms: high frequency, that hurts small wires in portable electronics, and low frequency, that hurts long wires like those buried underground in our power grid. Nukes put out both forms, while solar storms only affect us with the low-frequency type. The power industry has been downplaying the threat by ignoring data (or even intentionally using bad data), similar to the tobacco / sugar / oil / etc industries. Politicians and the military complex have been overplaying the threat to get more budget / justify war. The science around the topic is pretty bare. We need a lot more work and action. There isn't much you can do to prepare for an EMP beyond what you'd normally do to prep for grid failures and major war. Faraday cages do work, but they're often built wrong, even in professional settings. e.g. all the seams have to be welded shut, otherwise waves can sneak through, even where the paint coating on the metal touches (thus creating a gap / preventing the metal from actually touching). There isn't enough evidence to support that all of your modern cars would shut down. It's possible, but unlikely outside of the near area of a nuke blast.
