The book has great info, but read a lot more then this before implementing. Dangers exist with Hi Pressure, DC voltages. Science can be fun but a fully charged 1 quart Lyden Jar, or a 2 liter plastic soda bottle Lyden Jar will knock you down. It can be lethal. Read, then read again, don't experiment alone and make sure everyone can do CPR(having number for EMTS is good too). When they tell you make your own lightening, remember the dangers of lightening. Other then that, there are process' that are downright dangerous just to make, (electrophorus). The finished product is safe enough(maybe), but the process of manufacture is tricky and dangerous.

Other then that 5 stars, great, you will develope respect for that "Humble" foot dragging on the rug static snap you give the dog on his nose. You will understand why they ground your car at toll booths, before you hand the person at the booth.

Finally this book IS NOT for children. High Schooler Seniors maybe. BUT WITH SUPERVISION, CLOSE SUPERVISION, a Lab setting is preferential, with fire extinguishers, First Aiders and people who can tell if you are about to reach X-Ray Potentials.

There is an old saying to the effect: If you steal from one, it is plagiarism. If you steal from many, it is research.

On that basis, this is a well-researched book.

Without actually counting pages, my impression is that roughly a third of the book consists of facsimile reproductions of 100-150 year old news releases, advertisements, and journal reports. Most of the illustrations and pictures are of similar age.

The author does go into loving detail with regards to the construction of his machines -- essentially a copy of a Wimshurst with a modern drive system (dual axle-mounted motors vs one motor/crank driving a straight and a crossed belt).

The chapter on theory is only 5 pages long, and 3.5 of those are facsimile reproductions. I'm also surprised the author managed to get any output from his version of Kelvin's water drop generator -- his illustration shows the drops formed inches above the induction rings. A working device needs the drops to break loose from the water source just at the point of induction. In order for the drop to retain the charge as it falls into the collector it has to have the "repelled" charge pass from one-side, which means a continuous circuit from nozzle through source to other nozzle.

If deciding between this book, and A. D. Moore's "Electrostatics" (which was finally reprinted in 1997, 30 years after the original release), I recommend one consider "Electrostatics"

There's a lot of material floating around the web and bookstores that deals with Tesla and related topics. However, when it comes to good old fashion electro-statics, there is no where near the same volume of information. In fact, I've found four books pretty much cover the field -- at least for my money. Something to consider when contemplating a purchase of books on niche subjects such as electrostatics, books tend to go out of print rather fast. The print runs are small, and often the author or publisher will not reprint. This means, get the book while you can. It might be oop and only available on the secondary collectors market later.

Homemade Lightning (R.A. Ford) -- If you are interested in putting together an electrostatic device, this is the book for you. Lots of how-to with pictures and explanation. I think as a first book this is your best bet. And as a book for creating running examples, this is your best bet. However, I don't believe I would want to have just one book on the subject. The other three books mentioned below add their own dimension to the subject and are (in my opinion) worth the few dollars needed to create a mini-library on the subject.

Electrostatic Experiments (G.W. Francis) -- The subtitle for this book is "An encyclopedia of early electrostatic experiments, demonstrations, devices, and apparatus." The book lives up to its name. A great book for an overview of the field. I know it sounds a little silly, but the nice bright white paper and crisp illustrations are a real boon to this book. The font is well chosen and the leading is easy to read. In this book you will find reference to odd-ball experiments that other books just don't get around to talking about. For example, Eggs illuminated. (p.200) and Illumination of oranges (p.201). If you are looking for demonstrations or ideas for creating new displays for lecture or theater, this book has plenty of inspiration.

Electrostatics (A.D. Moore) -- A nice home experiments how-to book. The book is a little chatty in parts. I liked this. The author speaks with a direct, sitting across the table, style.

Static Electricity (J.H. Pepper) -- This material is extracted fom Cyclopaedic Science Simplified 1889. I use this for historical reasons and to poke around in. The book since it was written in 1889 assumes a fair degree of background by the reader. Great pictures and some nice explanations of how things work. You just need to be able to penetrate the older text.

This is an area of science that seems neglected, hidden in the back room of the "mad scientist". however, this book details both traditional and moderns means of obtaining, using, measuring & studying aspects of static electricity, including history. Several projects containing relatively common materials compliment the theory. The author is very open minded about science in general, although sometimes to the extreme. All in all, a very informative, even enjoyable read for anyone interested in high voltage electrostatics.

This is a must buy book for the electrical experimenter and science/physics educator. Very well written with unusual and unexpected material. Beautifully illustrated. Great plans for Wimshurst machine to make 14 inch sparks! Kinetic gravity and countergravitation experiments/information and more!

This book was and still is an indespensible guide to me and anyone else intereseted in starting out in electrostatics. It gives a wonderful overview of the principles involved, and take the reader on a thourough tour of how to go about building both sectorless-Wimhurst and Van de Graaff generators. A must have for electrostatic enthusists

This book is eye opening in that it awakens you to the fact that many traditional explanations of electricity do not explain all of the properties of electricity. A wonderful reference work. The illustrations are old, perhaps because the research seemed to stop around the 1930's. His chapter 6 on "Theories of generator operation" is excellent. His statement that "It is fair to say that there are as many theories as there are inventors of original generator designs." inspirers you to learn about all of the other designs. The book is packed with extensive references and I have recently acquired many of them. Although his references concerning Nikola Tesla are not pronounced, at least he mentions him in chapter 21 "Some philosophical conclusions and insights". Final answer: If I lose the book, I'll buy another!

I'm well into it now, so I've gotta finish, but damn! This thing is neither cheap nor easy to build.

At a casual glance, the instructions look fairly straight forward, but once you've got your materials (a shopping list at the beginning would be super helpful) you realize that the drawings leave some things to be desired (like, in many cases, dimensions)...if the drawing you're looking for is there at all. With a little head-scratching though you can sort it all out.

I've spent somewhere between $250 and $300 on the materials alone. You can buy a Wimhurst kit from Edmund Scientific for $120 but, y'know... its not as cool as making your own...

Tool-wise, its good to either have, or know somebody who has a drill press, lathe, router and various saws and sanders. I don't mind 'cause I'm a tool junkie- I needed a (good-ish) excuse to buy a lathe- but start factoring that in to your overall cost...

All that said though, the plans for the dirod in A.D. Moore's book don't look any clearer.

If you want to build your own spark machine, its probably good to understand the principle behind the machines and just start going at it. The drawings and diagrams in the book are good for setting you off in the right direction if nothing else... after all: the first people to develop these machines started off with nothing more than an idea- you get to start with some reasonably good drawings and a knowledge that if you stick close to the plans you'll get something that works.

Homemade lightening is only really valuable for it's in depth explanation of the authors own devices. There is also a lack of explanation of electrical theory in this book which the author probably justifies by saying that it doesn't have a strong basis anyways. Since throughout the later chapters he lividly explains how current theories have huge holes in them. The latter half of the book works outside of everything you've ever learned about physics, which was something of a disappointment. Some solid explanation of electrostatic principles with updated graphics would have been much more satisfying then the chronology of weirdness presented at the end. The total effect of first, not explaining electrostatic principles, and then providing highly technical and unsolved problems to the reader, leaves the reading either, in awe of R.A. Ford, or simply confused. A.D. Moore's Electrostatics is better for understanding electrostatics and for not having odd theories thrown at you. Another thing, Ford keeps saying how you should `visualize' the electric field to understand it, yet he only has one diagram of fields, and that's of gravity.
