I live a main road in the country. Sitting reading quietly in my house at night I often wish I had a very small EMP generator. First you hear (or more accurately feel) the thump thump thump of the base from a car which is maybe a couple of hundred metres away. This gets louder and louder until the car passes (interesting demo of the Doppler affect) and then gradually fades. What it's like inside the car is anyone's guess, but I wouldnt give much for the driver's hearing in a few years time. One press of my EMP button and silence, apart from "WTF?" from the driver! I could also use it on motorbike electrics on summer Sunday afternoons when the local organ donors are having an organised ride, and take about 20 minutes for all several hundred of them to pass.
Rant over - I feel better now!
Sorry for the thread drift.
