A few days ago I read a book about EMP attack survival along with solar storms. Both are related events that involve powerful bursts of electromagnetic energy which can affect electronics. Its not a light subject for sure, but it is one that requires study and analysis.
I listened to an informative podcast about solar storms and electromagnetic pulse (EMP) attacks today. You can listen to it by going here, which I highly recommend you do. The more you learn about both of these events, the better prepared you can become should they strike.
HT to Dr. Arthur Bradley for posting this on his blog.
