Hydropower Screws
Water screw conveyors have been in use for centuries. Their invention is attributed to Archimedes. However, the idea of using this Archimedean screw also as a hydropower screw to convert hydraulic energy into electrical energy did not emerge until the 1990s. More recently, hydropower screws have been used very frequently at hydropower sites and have now also attracted increasing interest from scientists and users worldwide. This is due to the machine's very good efficiency, it's simple and inexpensive design, and its fish compatibility. This book provides calculation fundamentals for hydropower screws. The author focuses on the description of the hydraulic processes and gives a design flow t...
Wasserkraftprojekte Band II
Dieses Buch fasst wichtige Veröffentlichungen zu Wasserkraftprojekten aus der Fachzeitschrift WasserWirtschaft zusammen. Dabei werden neuere Analysen zum Wasserkraftpotenzial dargestellt sowie über Entwicklungen und technische Besonderheiten berichtet. Beiträge über aktuelle Projekte runden die Zusammenstellung ab. In diesem Rahmen wird gleichfalls der Konflikt Ausbau der regenerativen Stromerzeugung und Anforderungen durch Richtlinien, Gesetze und Biodiversitätsstrategien thematisiert. Über die technischen und rechtlichen Aspekte hinaus werden auch Themen der Arbeitssicherheit, der Ökonomie und die Einbeziehung sozioökonomischer Aspekte in Wasserkraftprojekte erörtert. Mit einem Geleitwort des AGAW Vorsitzenden (Arbeitsgemeinschaft Alpine Wasserkraft) Herrn Molinari.
Archimedes in the 21st Century
This book is a collection of papers presented at the “Archimedes in the 21st Century” world conference, held at the Courant Institute of Mathematical Sciences in 2013. This conference focused on the enduring and continuing influence of Archimedes in our modern world, celebrating his centuries of influence on mathematics, science, and engineering. Archimedes planted the seeds for a myriad of seminal ideas that would grow over the ages. Each chapter surveys the growth of one or more of these seeds, and the fruit that they continue to bear to this day. The conference speakers contributing to this book are actively involved in STEM fields whose origins trace back to Archimedes, many of wh...

Stronger Than a Hundred Men
Like many apparently simple devices, the vertical water wheel has been around for so long that it is taken for granted. Yet this "picturesque artifact" was for centuries man's primary mechanical source of power and was the foundation upon which mills and other industries developed. Stronger than a Hundred Men explores the development of the vertical water wheel from its invention in ancient times through its eventual demise as a source of power during the Industrial Revolution. Spanning more than 2000 years, Terry Reynolds's account follows the progression of this labor-saving device from Asia to the Middle East, Europe, and America-covering the evolution of the water wheel itself, the development of dams and reservoirs, and the applications of water power.
