h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

If copyright allows, can you give some more detail, e.g. the internal content of the wheels. I have seen a diagram somewhere of how the electricity goes thorugh the wheels and plugs, is it possible to include it? Thanks

Unfortunately, the site rules don't allow graphics to be displayed, and if I pinched someone elses it would definitely be counted as a copyright theft... However, if you really wanted to know more, get hold of a copy of the book I mention at the end of the article, it's heavy going in places but has all the information you'd ever need on the workings of the machine itself
