Garden Shed EMP weapons
I remember many years ago my mate tekkie Jim, electronics genius and slight pyromaniac (cleared the weeds in my front garden using a plant mister, paraffin and a zippo), mentioning about EMP generation by suddenly collapsing a sphere of generated plasma.
At the time he had calculated that the device would fit in the boot area of a Ford Sierra estate (can't remember if you had to lower the rear seats or not)
The weapon would work over an area of about 40 meters sq..
His concept was diesel Ford Sierra estate, weapon in boot, racing Porsche 911's at traffic lights.
Get both parties revving engines, wait for amber light, trigger the device. All electrics die horribly ( including Porsche engine electrics and as a bonus the Porsche drivers digital watch ), diesel Sierra putts away from lights leaving Porsche driver with a big bill and the fact that he was beaten away from a set of lights by a diesel Sierra estate.
I had my doubts but when I saw Jim create a smoke screen using a tweaked stage smoke generator that completely covered 3 blocks of Victorian housing in Bradford in less than six seconds (the Royal Navy would have been seriously impressed), well what can I say....
