EM car disabler
talk
NPR's Robert Siegel talks with David Giri, president of the company ProTech,
about a device that could effectively end car chases by zapping car microprocessors
with a quick jolt of energy. Audio

This has a wierd familiarity. Once while tyring to place an article with
Ed Sander's "Cattle Report" in late 70s I looked into use of EM zappers
to disable electrical systems- in those day the whole electrical system was
target. Seemed as though the Air Force had funded some research along those
lines. We asked Dan Romanchik what he thought about this EM microprocesor disabler
story. Skeptical was Dan. Says Dan: Well, I'd have to see this to believe it.
The principle is simple enough, but the engineering is quite a bit more complicated.
For example, as they alluded to in the piece, the antenna a police car would
have to carry would have to be fairly big and directional, or else it will "zap"
not only the target car, but many other cars along the way. Both cars are moving
too, so that will have an effect on just how much electromagnetic energy gets
coupled into the target car. Finally, the good doctor pooh-poohed the question
about whether or not the target car would careen out of control, but I think
that might be a real possibility. I'm just a born skeptic, though."
