Wasn't Power Great?

My mom just sent me, two days ago, a clip from a book that talked all about ElectroMagnetic Pulses.  EMPs were used in, I believe, Oceans 11 and the Matrix.  The idea is that they send out a signal that neutralizes all electrons- so all electricity goes dead and all motors that require electricity (your car, for instance) go dead, and all batteries go dead.  Many of these exist as tactical weapons and cost a mere $100K.  Any number of countries could detonate several EMPs around the USA and send us into a tailspin in no time.  Imagine: in 5 days, all our food (and our ability to heat it, largely) is gone.  Computers- dead.  No transportation (all airplanes in the air would also go dead and crash).  That's... um... an unsettling picture.

So is this article that just came out today about presumed Russian or Chinese spies that have infiltrated the U.S. power grid and embedded software that could be activated later to dismantle our infrastructure.  All right!
