Vergleicht man das Leben, das Denken und die Schriften der alten Römer oder Griechen mit dem heutigen Leben, wird man keine wesentlichen Unterschiede in der Klarheit der Gedanken oder der Eloquenz der Erzählweise feststellen können. Vergleicht man jedoch die Technologien der alten Römer mit den heute bekannten Technologien, erkennt man, dass auf dem technischen Gebiet gewaltige Fortschritte geschaffen wurden. Entscheidende technische Fortschritte sind immer mit berühmten Erfindern und Wissenschaftlern verbunden. Diese prägen ihre Zeit und das Leben der nachfolgenden Generationen. Auf wichtigen technischen Durchbrüchen werden oft industrielle Imperien errichtet.Dieses Buch zeigt die technischen Aufgaben, denen sich die Erfinder gegenüber sahen, ihre Erfindungen und was aus diesen Erfindungen entstand. Das Buch soll Faszination für Technik vermitteln und zur wirtschaftlichen Realisierung eigener Erfindungen ermuntern, die zumeist durch das Anmelden der Erfindung zum Patent beginnt.

This book, drawing on fresh scholarship, investigates electrification in new places and across different time periods. While much of our understanding of electrification as a historical process is based on the seminal work done by Thomas P. Hughes in Networks of Power (1983), the scholars in this volume expand and revise Hughes¿ systems approach to suggest that electrification is a heterogeneous and contingent process. Moreover, the contributors suggest that the conquest of the world by electricity remains incomplete despite more than a century elapsing. Above all, though, this book provides context for thinking about what lies ahead as humans continue their conquest of the earth through electricity. As we become increasingly dependent on electricity to power our lights, heat and cool our homes, turn the wheels of industry, and keep our information systems humming, so we are ever more vulnerable when the grid runs into trouble.Chapter "Surveying the Landscape: The Oil Industry and Alternative Energy in the 1970s" is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
