The wind is a fickle source of power. Windspeeds are frequently too low to be of any practical use, so that windpower has generally remained a marginal resource. Since the inception of windpower around 1000 AD, technology has been deployed to obtain the most economical power from wind. The author traces its technical evolution, concentrating on the growth in understanding of wind and charting crucial developments in windmill design. The history of the windmill is focused on North Western Europe, drawing on the origins of the first horizontal windmills in Persia, Tibet and China. Industrial applications such as in textiles, papermaking and mining are examined. Gradually, windmills were improved but were finally eclipsed by steam engines in the nineteenth century due to increased levels of industrialisation. The book concludes with a look at the recent re-emergence of windpower as a viable source of power in the wake of the energy crisis.
This book is the most comprehensive empirical study to date of the social and technical aspects of milling during the ancient and medieval periods. Drawing on the latest archaeological evidence and historical studies, the book examines the chronological development and technical details of handmills, beast mills, watermills and windmills from the first millennium BCE to c. 1500. It discusses the many and varied uses to which mills were turned in the civilisations of Rome, China, Islam and Europe, and the many types of mill that existed. The book also includes comparative regional studies of the social and economic significance of milling, and tackles several important historiographical issues, such as whether technological stagnation was a characteristic of late Antiquity, whether there was an "industrial revolution" in the European Middle Ages based on waterpower, and how contemporary studies in the social shaping of technology can shed light on the study of pre-modern technology.
