This is the first comprehensive history of the steam engine in fifty years. It follows the development of reciprocating steam engines, from their earliest forms to the beginning of the twentieth century when they were replaced by steam turbines.
Anglo-American theoreticians have to a large extent dominated the formulation and study of modern naval strategy in Western countries. This Anglo-American dominance has resulted in a focus on how the superior power should exploit its superiority in order to realize its strategic objectives. The present study differs from other books on naval strategy by analysing a military strategy for the inferior power instead. Along with Tirpitz’s “risk theory”, The Jeune École is the most significant maritime strategy dealing with the dilemmas facing the weaker navy. This French body of naval thought is distinguished from other strategies of the weak by its elaborate prescriptions for the offensive use of naval forces. This book represents an unprecedented study of The Jeune École based on hitherto unexploited and unpublished primary sources from the Service Historique de la Marine.
Some 20 years after writing The Technological Society, Jacques Ellul realized how the totalistic dimensions of our modern technological milieu required an additional treatment of the topic. Writing amidst the rise of books in the 1970s on pollution, over-population, and environmental degradation, Ellul found it necessary, once again, to write about the global presence of technology and its far-reaching effects. The Technological System represents a new stage in Ellul’s research. Previously he studied technological society as such; in this book he approaches the topic from a systems perspective wherein he identifies the characteristics of technological phenomena and technological progress in light of system theory. This leads to an entirely new approach to what constitutes the most important event of our society which has decisive bearing on the future of our world. Ellul’s analysis touches on all aspects of modern life, not just those of a scientific or technological order. In the end, readers are compelled to formulate their own opinions and make their own decisions regarding the way a technique-based value system affects every level of human life.
How do we assess energy efficiency? The methodology proposed in this book links the efficiency at the system level to the data - flows and established knowledge - found at the process level. This analysis determines the dependence of the system efficiency on physical characteristics of its processes. Unless this is done, these characteristics may be sources of large errors, by factors of one hundred or more. The suggested methodology saves time of analysis and gives a realistic assessment of the remaining uncertainties. Complete energy systems cannot dissipate more energy than they extract, directly or indirectly. Historic exploitation of underground coal could not run a steam engine for operations which require more coal than it can lift. Can the agro-ethanol industry operate without external energies, (ie: is it more than self-reliant)?
