“EMP 101” A BASIC PRIMER & SUGGESTIONS FOR PREPAREDNESS is an interesting read. Once ALL the electricity gets turned off nationwide, most vehicles -- meaning cars, trucks and trains simply stop wherever they are -- transportation both personal and commercial stop. Don't be caught in a fly-by-wire airliner.

Food shipments stop; water pumps stop; sewage pumps stop; A/C gets warm and your furnace goes cold. Communications both commercial (radio & TV) and government (police and fire) cease. Hospitals will lose power and depending on how their back-up power is wired, they may lose that too -- not a good time to be in surgery.

I particularly appreciate the authors thoughts regarding the likelihood of an EMP "strike":
Quote:
Across six thousand years of recorded history mankind has known war. Across six thousand years humanity has tended to focus its best minds on the technology of war, to speak bluntly how to better kill our neighbors. Never has a weapon been invented that it has not ultimately been used. And ironically so many “new” weapons, when first revealed are declared to be so horrible as to render war unthinkable. And all have ultimately been used.
Time to invest in a large Faraday cage.
