Reading List: Adventures from the Technology Underground
- Gurstelle, William. Adventures from the Technology Underground. New York: Clarkson Potter, 2006. ISBN 1-4000-5082-0.
- This thoroughly delightful book invites the reader into a subculture of adults who devote their free time, disposable income, and considerable brainpower to defying Mr. Wizard's sage injunction, “Don't try this yourself at home”. The author begins with a handy litmus test to decide whether you're a candidate for the Technology Underground. If you think flying cars are a silly gag from The Jetsons, you don't make the cut. If, on the other hand, you not only think flying cars are perfectly reasonable but can barely comprehend why there isn't already one, ideally with orbital capability, in your own garage right now—it's the bleepin' twenty-first century, fervent snakes—then you “get it” and will have no difficulty understanding what motivates folks to build high powered rockets, giant Tesla coils, flamethrowers, hypersonic rail guns, hundred foot long pumpkin-firing cannons, and trebuchets (if you really want to make your car fly, it's just the ticket, but the operative word is “fly”, not “land”). In a world where basement tinkering and “that looks about right” amateur engineering has been largely supplanted by virtual and vicarious experiences mediated by computers, there remains the visceral attraction of heavy metal, high voltage, volatile chemicals, high velocities, and things that go bang, whoosh, zap, splat, and occasionally kaboom. A technical section explains the theory and operation of the principal engine of entertainment in each chapter. The author does not shrink from using equations where useful to clarify design trade-offs; flying car fans aren't going to be intimidated by the occasional resonant transformer equation! The principles of operation of the various machines are illustrated by line drawings, but there isn't a single photo in the book, which is a real shame. Three story tall diesel-powered centrifugal pumpkin hurling machines, a four story 130 kW Tesla coil, and a calliope with a voice consisting of seventeen pulsejets are something one would like to see as well as read about, however artfully described.
