its an idea tho...
Yes it is .. I replied to the wrong answer. Sry
Well .. I've noticed that if you can generate enough voltage to produce a spark and get that spark to discharge in a reflektor that interfears quite heavily with television and sattelites .. especially the digital signals.
I suggest a sparkcoil from a car, a battery, a sparkgap and a lid to a wok.
