Descriptions du produit
Revue de presse
Hands-on high-voltage experimentalists interested in electrostatic machines will love this book. Filled with design plans for building electrostatic generators and various high-voltage components, this book provides the necessary details to construct these devices. Like the first two editions, there are detailed plans describing the construction of a Wimhurst machine. This edition however, details a more simplified but larger and improved version than previously described. There is also now an entire chapter devoted to Van de Graff generators describing the principles of operation, construction, modifications for improvement, and making accessories. There are many illustrations and photos describing the construction of these generators as well as methods for making electroscopes, large capacitors, and an electrophorus. There are many tips and tricks revealed that show how to make various parts like high-voltage corona spheres, shorting rods, and terminals. Other topics include electrostatic motors, cold light, levitation, exploding wire experiments, and historical notes on unusual electric discharges. A revised bibliography and materials supplier list also made in this new edition.
Anyone with an interest in high-voltage electrostatics will find this book to be not only a "cookbook" for designing and building high-voltage generators but also an historical account of the Wimhurst and Van de Graff generators.(IEEE Electrical Installation Magazine 2003-01-15)
Présentation de l'éditeur
Covering theory and presenting electroscope and other construction projects and experiments, this handbook also includes experiments with electrohorticulture, gravitation and electricity, cold light, and electric tornadoes. Homemade Lightning is both an excellent first book for the building electrical experimenter and a superb book for accomplished experimenters who haven't spent much time with electrostatics.

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.
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.
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"
