Energy From Oceans And Moving Water

Power from water is an excellent energy source that we are exploring more and more. Readers are presented with the benefits or harm this energy source might cause to the environment, then they are asked to make up their own minds about its viability. This informative source is a great addition to any reader’s library.

Photographs, illustrations, and text introduce readers to energy conservation and the power of water as an energy source.

Engineers’ dreams and fossil energy replacement schemes can come true. Man has been tapping the energy of the sea to provide power for his industries for centuries. Tidal energy combined with that of waves and marine winds rank among those most successfully put the work. Large scale plants are capital intensive but smaller ones, particularly built in China, have proven profitable. Since the initiation of the St Malo project in France, similar projects have gone into active service where methods have been devised to cut down on costs, new types of turbines developed and cost competitiveness considerably improved. Tidal power has enormous potential. The book reviews recent progress in extracting power from the ocean, surveys the history of tidal power harnessing and updates a prior publication by the author.

Read Along or Enhanced eBook: This new series takes young readers through the exciting and often controversial world of energy. Covering different sources of energy, the eight volumes feature fictional student narrators interviewing experts who discuss the pros and cons of each, and the science behind them. Combining facts and balance, Examining Energy provides students with a clear picture of a topic on which the daily headlines and news stories too often flash more heat than light.

This book provides comprehensive coverage of hydrokinetic energy - power derived from moving water, including wave, marine, and tidal plants. While traditional hydropower is a well-established industry, advanced water power technologies that produce electricity from moving water without the use of a dam are now emerging in the renewable energy sector. These technologies, known as hydrokinetics, generate electricity from the motion of waves, the free flow of tides, ocean currents, or inland waterways. As part of its broad effort to advance the renewable energy industry, the U.S. Department of Energy (DOE) is funding various market acceleration projects designed to address key issues associated with hydrokinetic technologies that harness renewable energy from the nation's oceans and rivers. Hydrokinetic energy conversion devices are designed to be deployed in a stream or current, capturing kinetic energy from the flow of water across or through the rotor (which may take various forms) to power a generator without impounding or diverting the flow of the water resource. Conceptually, this is similar to the way wind energy conversion devices work. Wave energy conversion devices create a system of reacting forces, in which two or more bodies move relative to each other, while at least one body interacts with the waves. The body moved by the waves is called the displacer, while the body that reacts to the displacer is called the reactor. There are many ways that such a system may be configured, including: oscillating water columns (OWC), point-absorbers, attenuators, and overtopping devices. Setting for these various technologies include natural streams, tidal estuaries, near-shore environments, offshore and ocean locations, and constructed waterways. Technologies covered include wave energy conversion devices, terminators, oscillating water columns, point absorbers, attenuators, overtopping devices, in-stream tidal flow energy conversion devices (TISECs), horizontal axis, vertical axis, axial flow machines, open center turbines, ducted turbines, turbine matrix, helical turbines, heave wave devices, heave-surge wave devices, overtopping wave devices, and more. Contents include a thorough review of the potential environmental effects of marine and hydrokinetic energy technologies.

Wave energy, together with other renewable energy resources is expected to provide a small but significant proportion of future energy requirements without adding to pollution and global warming. This practical and concise reference considers alternative application methods, explains the concepts behind wave energy conversion and investigates wave power activities across the globe. Explores the potential of using the power generated by waves as a natural energy resource Considers the power transfer systems needed to do this, and looks at the environmental impacts

This volume will prove of vital interest to those studying the use of renewable resources. Scientists, engineers, and inventors will find it a valuable review of ocean wave mechanics as well as an introduction to wave energy conversion. It presents physical and mathematical descriptions of the nine generic wave energy conversion techniques, along with their uses and performance characteristics. Author Michael E. McCormick is the Corbin A. McNeill Professor of Naval Engineering at the U.S. Naval Academy. In addition to his timely and significant coverage of possible environmental effects associated with wave energy conversion, he provides a separate treatment of several electro-mechanical energy conversion techniques. Many worked examples throughout the book will be particularly useful to readers with a limited mathematical background. Those interested in research and development will benefit from the extensive bibliography.

As a result of the energy crisis of the 1970s, the United States invested millions of dollars for research and devleopment of Ocean Thermal Energy Conversion (OTEC). This technical report gives details of a project studying the potential use of OTEC.
