very highly recommended
Synopsis
The full title of Gurstelle's book is: Adventures from the Technology Underground: Catapults, Pulsejets, Rail Guns, Flamethrowers, Tesla Coils, Air Cannons, and the Garage Warriors Who Love Them. That pretty much explains what it's about. We're talking about regular people who like to make or invent some interesting devices. After living with a design engineer for many, many years, I have an understanding about the fascination certain people may have in building some of these things in their garage (and he may or may not have built a few of these devices over the years, but I'm not telling.)
Chapters included are: High Powered Rockets, The Technology of Burning Man, Tesla Coils, High-Voltage Discharge Machines, Hurling Machines, Air Guns, Flamethrowers, Electrostatic Machines, Rail and Coil Guns, and Robots. The book includes separate sections with more technological detail on particular devices. Gurstelle suggests that you can read the sections if you are interested in more technical detail, but a casual reader can skip them. The sections are interesting, easy to understand (at least they were for this amateur), and include illustrations.
Synopsis
The technology underground is a thriving, humming, and often literally scintillating subculture of amateur inventors and scientific envelope-pushers who dream up, design, and build machines that whoosh, rumble, fly—and occasionally hurl pumpkins across enormous distances. In the process they astonish us with what is possible when human imagination and ingenuity meet nature’s forces and materials. William Gurstelle spent two years exploring the most fascinating outposts of this world of wonders: meeting and talking to the men and women who care far more for the laws of physics than they do for mundane matters like government regulations and their own personal safety.My Thoughts:

You need to know that this book is an introduction to the various catapults, aircannons, flamethrowers, etc., not a detailed set of schematics on how to build your own and what materials you'll need. There are notes and a further reading section if you really need to explore making your own "Punkin Chunk" air cannon or a personal Tesla coil. (Really, if you are expecting detailed instructions in a 224 page book that covers a wide range of projects, then you need to rethink that position.)
Gurstelle had five conditions that had to be met for inclusion in the book. Projects had to be founded upon physical science, the inventors had to have amateur standing, there are elements of danger involved, every project is high energy, the projects are recognized by others (pg 11-13).
With shows like Junkyard Wars, BattleBots, and Monster Garage, the whole idea of building something fantastic out of, well, junk or parts, is a concept many people can understand. Be forewarned, however, that this is not a book for the young scientist in your family - well, it might be with the exception of a certain section on, shall we say, "male enhancement," that might not be considered appropriate.
Very Highly Recommended - and I really want to see the quarter shrinking device. Really.

Quotes:
The people profiled here do what they do largely without regard to economics, profit, government regulation, corporate or academic practices, or even good taste. Most laws (except for those of physics), regulations, and building codes are skirted or ignored. pg. 9
This book is about the art and science of making catapults, pulsejets, flamethrowers, Tesla coils, high-voltage electrostatic machines, high-powered amateur rockets, air cannons, rail guns, fighting robots, magneformers, and more. It is as much about the people who make them as it is about the culture that engenders their creation. pg. 10
This book explores the making of all sorts of dodgy machines, from high-voltage, high-powered electrical apparatus to vegetable shooting plastic cannons. All of them can be dangerous. And here is a final word of advice for those who, after reading this book, may be considering making their own flamethrower: don't. pg. 20
Rocketeers both need and love wide-open spaces—the wider the better. Amateur rocket builders, especially those who specialize in building the largest and most powerful rockets, want only a couple of things: a lot of flat, open, unpopulated land in which to recover their rockets after flight, and clear, sunny skies. This makes places such as Texas, Kansas, and the Canadian prairie provinces ideal spots for LDRS gatherings. pg. 23-24
What rocket makers care about most is the physics quantity called "total impulse." Total impulse is the product of the force acting on a rocket (the thrust) multiplied by the amount of time the thrust is applied. Expressed mathematically, it is: Total Impulse = Average Thrust ´ Burn Time An engine that applies a lot of thrust, for a long period of time, is a high-performance engine. To a rocket engine maker, the goal is lots and lots of impulse. pg 28
This piece of equipment shrinks U.S. legal tender - Washington quarters - literally instantly, and powerfully. pg. 96
The World Championship Punkin Chunk is a key stop on any tour of Technology Underground festivals. It brings together some of the most massive, powerful, noisy, and entertaining technology in the world. pg. 107
As the gun holder steels herself for the expected recoil, you unscrew the cap to the combustion chamber and charge the gun with a two-and-a-half-second burst of Right Guard antiperspirant, which is mostly an aerosol mixture of butane and propane. pg. 141

Wow - very interesting...male enhancement?
Just a thought....
Did they mention anything akin to OCD, savant-ism, autism or lack or social skills with any of these folks?
Sometimes the negative side to high intelligence.
Shellie, many of the people he mentioned seemed very sociable, but then it was all in the context of them building these devices and showing them to other enthusiasts with similar interests. No mention of OCD, Savants, or autism that I recall, although an autistic person who is highly functional and doing something in their area of interest wouldn't necessarily seem odd around a bunch of other enthusiasts. On the other hand, several of the people mentioned were definitely not a part of mainstream society.
thanks Lori - very interesting indeed.
The links between high intelligence and creativity to those disorders as well as mental illness for the later completely fascinates me.
