Hi.
I was wondering about a self destruct system for a car that would be used to transport sensitive documents or items that could cause serious problems if they fall into the wrong hands. Sort of like the ability to scuttle a ship when it's being taken over and there's no hope.
Would the following work? You have a console on the dashboard with a keyed activation system and a timer that can be set to some length of time to permit abandoning the car before it blows. When the timer reaches zero, all the safeties on the engine are disabled and then the mechanism revs and revs and revs and revs the engine far past normal safe limits until it blows it's top. The timer could also be activated by remote, and when active would emit a shrill 100 dB alarm whine.
Not that I'm going to build this rigged-up car or anything, but I'm curious if this would work. I think I saw a self destructing car in a movie once, and then I got interested in the idea.
