On the subject of scale; check out the Van de Graff generator at the Boston
Science Museum sometime.  It's about three stories high, with balls that are
quite large in diameter.  It can generate quite a few mega-volts of "static"
electricity.  The staff there calls it lighting simulator, and I'd have to
agree with them!  If you go, the winter is the best time because the drier
air allows a larger charge to be built up before the resulting discharge;
i.e. bigger booms.

In case you are wondering why anybody would want to build such a thing, it
was build in the early part of the centruy (20's or 30's I think) as part
of experements on splitting atoms.  Of course today we have much better
ways to split atoms, and this very large generator has become a show and
tell piece for the Boston Science Museum.  Oh yea, the entire generator is
in a Faraday cage so that the audience is safe.
