This might sound very stupid but I am concerned, and this question also extends to my computer. What is in danger in the case of an EMP blast?

I have heard of switches that would cut all power in the case of a charge as big as an EMP. Does this mean it only affects things that are plugged in? I thought EMP blasts meant bye bye car...

I would really appreciate anybody's knowledge on this! Thanks guys.



PS: More about the iPod situation. I love music. I need it. I plan to build a Hand crank Generator that could of course be used to charge an iPod. (and later I plan to build something connected to a bike so I could actually get more than 5 minutes worth of powering anything <img src="/images/graemlins/tongue.gif" alt="" /> )
