In november 1995, the ETV - student association of EE, Delft University of Technology, The Netherlands - allready did a similar thing. It's in Dutch, but there are some pictures.
Some industrial strength inverters (AC/AC) for induction motors use an inner DC-link (at a few kilovolts). Storing something like 40 MJ (Yes, fourthy megajuoles) Now there's some energy to release..
how would they work?
Well, I woul call it a weak spot in the wall of your supposed-to-be-strong-fortress. It's not like you see the door and just need to try to find the right key. That's brute force on the frontdoor.
If an encryption algorithm is not completely 'clear', that is, it contains parts, whose design strategy/philosofy is a mistery, like the substitution boxes in DES, there is a risk it contains a backdoor.
For DES: if one could find an analytical expression, that relates the input os the s-boxes to the output... you're a winner! Then you would have found the weak spot in the wall, just push gently, and you're in.
It's nice to be in Holland: we have a graduate course on Encryption (DES, RSA etc.) It seems this is sort of an impossibillity in the US.
Use the technology as a mouse. One blink would mean a single click. Two blinks is a double click. Great!
But then again, how to perform accurate drag-n-drop?
