No worries, a lot of people search about EMP every day. Smaller EMP devices were (are?) commonly used to rob poker/slot/vending machines. I have no idea of the truth behind this, but there are homemade devices being sold online, sometimes disguised as "research" devices with photos showing how they can turn on a CCFL lamp from distance, while others blatantly declare their purpose.
