Description
Excerpt from Lightning Conductors and Lightning Guards: A Treatise on the Protection of Buildings, of Telegraph Instruments and Submarine Cables, and of Electric Installations Generally From Damage by Atmospheric Discharges
This book is the outcome of a couple of lectures which in 1881 I was asked by Sir Trueman Wood, Secretary to the Society of Arts, to deliver in memory of the late Dr. Robert Mann, an enthusiastic advocate of lightning rods in South Africa and elsewhere, and they are published with the sanction and approval of the Society.
Experiments made by me shortly before the lectures showed me that several of the current ideas on the subject were unfounded and incorrect; mainly because the momentum of an electric current and the energy of an electrostatic charge had both been more or less overlooked by those who had treated the subject. The application of the known fact of electrokinetic momentum revolutionized the treatment of certain phenomena. The old drainpipe idea of conveying electricity gently from cloud to earth was thus proved fallacious, and the problem of protection became at the same time more complex and more interesting.
An idea at one time got abroad that my experiments proved existing lightning conductors to be useless or dangerous; this is an entire misrepresentation. Almost any conductor is probably better than none, but few or no conductors are absolute and complete safeguards.
