Hi Jim,
This is something that happens to every stationary capacitor I have run
across so far. People who work with really large caps (some Ham's) are
usually told to strap them down when not in use because the voltages they
produce can be rather bad.
The root cause I believe is the aether which gets "stored" in the caps
dielectric. After a while more and more units of aether get sucked in an
eventually you can form an increasing potential difference between the two
poles.
Next ALL you have to do is find a way to enhance the effect. :)
