Book Description
The annual seasons and rhythms of the desert are a dance of clouds, wind, rain, and flood—water in it roles from bringer of food to destroyer of life. The critical importance of weather and climate to native desert peoples is reflected with grace and power in this personal collection of poems, the first written creative work by an individual in O'odham and a landmark in Native American literature. Poet Ofelia Zepeda centers these poems on her own experiences growing up in a Tohono O'odham family, where desert climate profoundly influenced daily life, and on her perceptions as a contemporary Tohono O'odham woman. One section of poems deals with contemporary life, personal history, and the meeting of old and new ways. Another section deals with winter and human responses to light and air. The final group of poems focuses on the nature of women, the ocean, and the way the past relationship of the O'odham with the ocean may still inform present day experience. These fine poems will give the outside reader a rich insight into the daily life of the Tohono O'odham people.

Book Description
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.

Book Description
Fundamentals of Ocean Renewable Energy: Generating Electricity from the Sea presents the basic concepts of mechanics and introduces the various technical aspects of ocean renewable energy. Contents follow a logical sequence, starting with hydrodynamics and then separately examining each conversion technology, with special focus on tidal energy, offshore wind and wave energy, as well as current and ocean thermal energy conversion (OTEC). The authors explore key topics for resource characterization and optimization, such as monitoring and measurement methods and ocean modeling. They also discuss the sustainability, planning, integration and distribution challenges for the implementation of these technologies, including co-location with other systems. Finally, case studies of ocean energy sites and devices allow for a better understanding of how ocean energy conversion works in real-world settings. This book is an invaluable resource for students at graduate and senior undergraduate level engineering (ocean, mechanical, and civil) and oceanography with prior knowledge of fluid mechanics and mechanics of materials. - Presents the fundamental physics and theory behind ocean energy systems, covering both oceanographic and engineering aspects of ocean energy - Explores the most widely adopted conversion technologies, including tidal, wave, offshore wind, ocean thermal and currents

Book Description
Also called energy scavenging, energy harvesting captures, stores, and uses "clean" energy sources by employing interfaces, storage devices, and other units. Unlike conventional electric power generation systems, renewable energy harvesting does not use fossil fuels and the generation units can be decentralized, thereby significantly reducing transmission and distribution losses. But advanced technical methods must be developed to increase the efficiency of devices in harvesting energy from environmentally friendly, "green" resources and converting them into electrical energy. Recognizing this need, Energy Harvesting: Solar, Wind, and Ocean Energy Conversion Systems describes various energy harvesting technologies, different topologies, and many types of power electronic interfaces for stand-alone utilization or grid connection of energy harvesting applications. Along with providing all the necessary concepts and theoretical background, the authors develop simulation models throughout the text to build a practical understanding of system analysis and modeling. With a focus on solar energy, the first chapter discusses the I−V characteristics of photovoltaic (PV) systems, PV models and equivalent circuits, sun tracking systems, maximum power point tracking systems, shading effects, and power electronic interfaces for grid-connected and stand-alone PV systems. It also presents sizing criteria for applications and modern solar energy applications, including residential, vehicular, naval, and space applications. The next chapter reviews different types of wind turbines and electrical machines as well as various power electronic interfaces. After explaining the energy generation technologies, optimal operation principles, and possible utilization techniques of ocean tidal energy harvesting, the book explores near- and offshore approaches for harvesting the kinetic and potential energy of ocean waves. It also describes the required absorber, turbine, and generator types, along with the power electronic interfaces for grid connection and commercialized ocean wave energy conversion applications. The final chapter deals with closed, open, and hybrid-cycle ocean thermal energy conversion systems.

Book Description
This timely volume provides a comprehensive review of current technology for all ocean energies. It opens with an analysis of ocean thermal energy conversion (OTEC), with and without the use of an intermediate fluid. The historical and economic background is reviewed, and the geographical areas in which this energy could be utilized are pinpointed. The production of hydrogen as a side product, and environmental consequences of OTEC plants are looked at. The competitiveness of OTEC with conventional sources of energy is analysed. Optimisation, current research and development potential are also examined.Separate chapters provide a detailed examination of other ocean energy sources. The possible harnessing of solar ponds, ocean currents, and power derived from salinity differences is considered. There is a fascinating study of marine winds, and the question of using the ocean tides as a source of energy is examined, focussing on a number of tidal power plant projects, including data gathered from China, Australia, Great Britain, Korea and the USSR.Wave energy extraction has excited recent interest and activity, with a number of experimental pilot plants being built in northern Europe. This topic is discussed at length in view of its greater chance of implementation. Finally, geothermal and biomass energy are considered, and an assessment of their future is given.Each chapter contains bibliographic references. The author has also distinguished between energy schemes which might be valuable in less-industrialized regions of the world, but uneconomical in the developed countries. A large number of illustrations support the text.Every effort has been made to ensure that the book is readable and accessible for the specialist as well as the non-expert. It will be of particular interest to energy economists, engineers, geologists and oceanographers, and to environmentalists and environmental engineers.

Book Description
This book assesses India’s role as a major power in the Indian Ocean. Many see the Indian Ocean as naturally falling within India’s sphere of influence but, as this book demonstrates, India has a long way to go before it could achieve regional dominance. The book outlines the development of Indian thinking on its role in the Indian Ocean and examines India’s strategic relationships in the region, including with maritime South Asia, the Indian Ocean islands, East Africa, the Middle East, Southeast Asia and Australia. The book then discusses India’s ambivalent relationship with the United States and explores its attitude towards China’s growing power in the Indian Ocean. It concludes by discussing the region’s evolving strategic order – does India have what it takes to become the leading power in the region?
