Comment Shaped charges? (Score 1) 287
Hi all,
I've done some tests on old mobile phone packs and they can and do explode in flames if overcharged then shorted.
Had to use a screwdriver to initiate the reaction but its possible that overcharge-induced internal short could have been enough.
Then, the phone's battery casing acted like a shaped charge, in that the hot gases were briefly confined and burst out of one area. The force generated would be enormous (these things are used to compress plutonium in "Physics Packages") !
Lesson learned: do not do Li charging in software, its far too risky.
And they allow portable DVD players on planes? Li cells 10* the volume of mobile packs + overcharge + strategically placed drawing pin + fist = Instant incendiary device, Macgyver-style :)
Oh, and there's the favourite camera flash hooked up to battery trick, this also induces rapid disassembly with flame :)
-A (IANAT) Next stop Gitmo... LOL!
