      There's an excellent solution to this guy's problem.  I have some
misgivings about posting it, but since there are other ways to make various
sorts of destructive devices, I've decided to do so.

      The highest power-to-weight ratio in batteries is found in the Polaroid
PolaPulse (TM) battery.  This is a flat object about the size of a playing 
card and about 2mm thick.  One is inside every Polaroid film pack.  These 
units are designed to deliver about 10-20 amps, as I recall, for a second
or so at a time, and provide the energy to drive the motor that forces the film 
through the developing rollers.  You can buy the batteries from Polaroid in
a somewhat more convenient form than one obtains by dismantling a film
cartridge, and Polaroid sells a developer's kit for these units.
