I wonder if disposable cameras will be sold at airports soon, fairly handy
capacitor in there.

A better way is to use a couple of old-style iron core transformers.  Hook
them up to your laptop battery in reverse, i.e. a 240v to 6v transformer
will also convert 6v to 240v.  Wire up a couple in series, and you have a
handy cattle prod.  You'll need an oscillator, a DPDT relay can work here.
The output won't be pretty under a scope, but still be capable of warding
off "people who didn't like your face".

The bulk of these are a bit hard to crack open while sitting in your seat,
but that's easy circumvented.
