Did you really think I was being serious :|
Jokes are only funny when they make sense. There's no such thing as a jerk store.
One thing I've always wanted to do was put iron bars in front of my window then electrically isolate odd bars from the even bars and tie both of them to some power source. The bars would be like this:
+ - + - + - + - + -
Touching an odd bar and an even bar at the same time would knock you on your ass.
To make sure it's effective, it would be jacked up to 480V by running it through a transformer. It would be protected from short circuit current by putting a strong inductor in series with it, similar to how a fluorescent light works. Having an inductor limit it to 0.25 amps would prevent it from starting a fire or tripping the breaker, but at the same time 0.25 amps is more than enough to kill a robber or a dog or that annoying kid that lives next door.
If you can figure out how to make such a system work for a car, my hat goes off to you :biggrin:
