EMP => PULSED PHONE DESTRUCTION!

  Hi, everybody, check this out:


 Yesterday I connected 2 capacitors, rated for 2500V, 1.1uF, in parallel 
to my 2300V, 0.5A microwave oven transformer. I connected their outputs 
to a home made spark gap that consisted of 2 very large steel bolts 
mounted on an insulated metal base. The capacitors take a fraction of a 
second to charge up and their discharge makes an almost continuous arc, 
that sounds like a 747 taking off (that thing is LOUD!!!). They'll melt 
and vaporise anything, and are as bright as an arc welder.
 Anyway, buy spacing the gap to about 2.5mm, I could get the gap to fire 
only once, when I flipped the switch. It sounded like a rifle going off. 
A LOUD, dry sound, that could be heard echoing away like thunder.
 Well, to make a long story short (I'll not go into details on how you 
can use this to turn worms into fireworks or explode water and thin 
wire), I got a call from a friend in my cordless phone. In the middle of 
the conversation I said: "Hey, Listen to this!" I put my earmuffs on, 
placed the phone 20cm from the gap (a little more than half a foot 
distance), and fired it dry. There was the loud noise. I took the 
earmuffs off and said: "So, what do you think"? There was no reply. The 
phone was permanently destroyed by electromagnetic pulses that induced 
high currents on its circuits and fried the chips.
 I must admit that it was quite a stupid experiment, and I knew the 
potential danger of EMP. But I never expected it to be THAT powerful.
 I found out that if a different phone is moved away to, say 1 or 2 
meters, it will automatically shut down when the gap is fired. At 4/5 
meters it will make static noises and the interference stops at 10 
meters or so.
 Since Tesla Coils use a circuit very similar to this one (discharging 
large capacitors trough spark gaps), they should have similar effects. I 
have never seeing any mention of this anywhere, but perhaps the 
interference produced by TCs is due to their spark gaps, not the 
secondary. I am sure at least some of it is...Perhaps shielding the 
spark gap with metal would reduce the interference produced by the Coil. 
Has anyone ever tried this???
 Give me your thoughts on that...

 Sam.

 P.S. You can use solar panels to detect EMP...
