The deceptively simple task of making a mechanism which would turn forever has fascinated many famous men and physicists throughout the centuries. In fact, the basic tenets of engineering grew from the failures of these perpetual motion machine designers. This work offers an illustrated overview of perpetual motion machines and their inventors.

About the Author
Arthur W.J.G. Ord-Hume is a qualified mechanical engineer who, after leaving the Royal Air Force, designed civil and military jets. A postwar pioneer of private flying, he later designed and produced small planes. He has written widely on aircraft instruction and received many international awards.

Make a machine which gives out more work than the energy you put into it, and you have perpetual motion. The basic tenets of engineering grew from the failures of perpetual motion. The deceptively simple task of making a mechanism which would turn forever fascinated many an inventor and, perhaps surprisingly to us today, a number of famous men and physicists applied themselves to the task.

Affectionate Look at the Pursuit of an Impossible Dream
By A Customer
Mr. Ord-Hume, an engineer himself, wrote this book after being entreated to aid with a television show on the subject of Perpetual Motion in Britain; he had already kept a file on perpetual motion machines as a curiosity he kept running into while studying the history of machines, and evidently was inspired by these two separate things to write an entire book on the subject. His book reads as more than a history of individual inventions and their creators than an engineering treatise, which puts not only the machines but the whole pursuit of perpetual motion into perspective; originally conceived as a way to simply save work, then as the holy grail of early engineering, and finally as a way for con men to bilk investors out of their money, the author catalogues the efforts of very interesting and often brilliant men. He explains how the machines were supposed to work, why they won't, and even occasionally gets inside the head of the inventors. He never makes fun of them however, and even credits them with inadvertantly furthering science and physics by building ever-more complex machines that won't work due to various physical principles that are discovered. Many brilliant men who could have been famous contributors to science wasted their lives and fortunes (and occasionally their sanity) pursuing the idea of free energy, no to avail. There was one exception...a clockmaker named Cox who built a perpetual clock powered by a barometer. But is it true perpetual motion? You decide.
My only quibble with the book is that his qauint style of writing does become more than a bit convoluted at times in trying to make his point, and that he does not go into enough detail at times explaining why a machine does not work, apparently assuming (and probably correctly) that the reader will not be able to follow the physics involved. However, the book is very entertaining and thought-provoking to anyone interested in mechanics. Some of the concepts are truly brilliant, especially considering how long ago they were conceived; except for the annoying fact that they wouldn't work. No matter how big a skeptic, the reader will probably find himself (or herself) doodling their very own machine on a piece of paper...and convincing themselves it could work. An esoteric and highly entertaining work for mechanics enthusiasts.

An impressively documented history of the discovery and utilization of perpetual motion machines
By Midwest Book Review
Perpetual Motion: The History Of An Obsession by Arthur W.J.G. Ord-Hume is an impressively documented history of the discovery and utilization of perpetual motion machines. As for most scientists and inventors, perpetual motion had become the potential discovery that would enable the generation of a much greater technology, for some it had become an obsession, and still today there may remain a number of mysterious processes in which perpetual motion seems without explanation. Discover the most intriguing history of perpetual motion in Perpetual Motion which is very highly recommended to all readers especially to those students of general sciences and aspiring mechanics and invention, as well as non-specialist general readers with an interest in alternative science.

Entertaining and informative
By Jim Davis
I was impressed by author Ord-Hume's aviation titles and discovered he had a website. The author's interests extend way beyond aviation and include the subject of the present book. Although dating from the 1970s a later printing was still available. The book appears not to have been brought up to date; the only new addition being a new preface by the author.
The book is very well organized and thought out. He begins with the bare basics. Perpetual motion is a concept that defies easy definition but the author does a commendable job dividing perpetual motion machines into those that violate the first law of thermodynamics and those that violate the second law of thermodynamics. His explanation of the second law is somewhat weak; it is probably because of his attempt at simplification which goes too far.
Then we are treated to a fairly chronological feast of various perpetual motion machines that have reared their heads over the years. The illustrations are from the relevant periods and aid the reader immensely in following the text. In the few cases where a machine is not illustrated it can be a challenge to visualize it based solely on description. It is fascinating that there were trends in perpetual motion machines as the centuries passed, self-contained mills, overbalancing wheels, electromagnetism, etc.
The author also spends several chapters describing machines that actually succeeded in producing very long running (centuries) motion. Barometric self winding clocks, ever-ringing bells, and radium powered devices are a few. The author also writes a somewhat confused chapter on nuclear energy and its relevance to the subject. Today he could have added material on the many solar powered devices that mimic perpetual motion. He also includes a chapter on various perpetual lamps that have been reported over the ages.
The author contends, barring outright frauds, that the quest for perpetual motion was by no means wasted effort and that much positive good came of it. He regrets that perpetual motion seekers seem to be a dying breed and attributes this to a decline in values in modern society. I think he misses the boat here. In the decades following this book there have been many overtly fraudulent but also many honest but misguided attempts to discover a "free energy" or "over unity" device. The name "perpetual motion" has fallen from use but the lure and those that chase after it are still very much with us.
Highly recommended. It's interesting that the publisher is noted more for its occult, conspiracy, and psuedoscientific titles if the catalog of titles on the final few pages of this book is anything to go by. They are to be congratulated all the more so then for bringing this sane and sober title back into print.
