With this volume in the STEM Road Map Curriculum Series, you can! Hydropower Efficiency outlines a journey that will steer your students toward authentic problem solving while grounding them in integrated STEM disciplines. Like the other volumes in the series, this book is designed to meet the growing need to infuse real-world learning into K–12 classrooms.This interdisciplinary, four-lesson module uses project- and problem-based learning to help students create a highly efficient dam that has a minimal impact on the environment. Students will explore the use of natural resources to provide energy needs, specifically hydropower, while exploring the workings of watermills, wind turbines, and generators to help build an understanding of the effects of dams. In creating their dam, they will learn about the various types of alternative hydropower sources, including wave and tidal power, and track the progress of electrification in the U.S. on a timeline; alongside researching the positive and negative consequences of hydropower.To support this goal, students will do the following: Use the engineering design process (EDP) to create a design for a dam, wind turbine, and water wheel Compare and contrast renewable power sources Evaluate power sources for efficiency Identify positive and negative consequences of human modifications of the environment Identify and describe how several sources of renewable energy are used across the U.S. Use mapping skills to determine where natural resources are being accessed for energy usage Effectively utilize shapes, materials, and measurements to create a model of a hydropower system The STEM Road Map Curriculum Series is anchored in the Next Generation Science Standards, the Common Core State Standards, and the Framework for 21st Century Learning. In-depth and flexible, Hydropower Efficiency can be used as a whole unit or in part to meet the needs of districts, schools, and teachers who are charting a course toward an integrated STEM approach.

Hydropower Screws: Calculation and Optimal Design of Archimedean Screws
by Dirk Michael NuernbergkWater 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 that can be used to design hydropower screws. The hydraulic behavior, dimensions, speed, efficiency, forces acting on the screw such as sag or lift, as well as the arrangement of the gearbox and the choice of generator are discussed. The theoretical equations, some of which are newly derived, are applied using examples. Finally, a design flow is given that can be used to easily adapt an optimally designed hydropower screw to a location. New findings presented in various scientific publications have been incorporated into the translation of the second German edition. In addition, experiments were carried out at different locations, which led to a better understanding of the available data basis. This has allowed the theoretical predictions of this book to be confirmed experimentally. In addition, the author has investigated a number of faulty installations and has been involved in the design of successful working waterpower plants equipped with hydropower screws.
