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.

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.

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

The waves that animate the surface of the oceans represent a deposit of renewable energy that for the most part is still unexploited today. This is not for lack of effort, as for more than two hundred years inventors, researchers and engineers have struggled to develop processes and systems to recover the energy of the waves. While all of these efforts have failed to converge towards a satisfactory technological solution, the result is a rich scientific and technical literature as well as extensive and varied feedback from experience. For the uninitiated, this abundance is an obstacle. In order to facilitate familiarization with the subject, we propose in this work a summary of the state of knowledge on the potential of wave energy as well as on the processes and technologies of its recovery (wave energy converters). In particular, we focus on the problem of positioning wave energy in the electricity market, the development of wave energy conversion technologies from a historical perspective, and finally the energy performance of the devices. This work is aimed at students, researchers, developers, industry professionals and decision makers who wish to acquire a global perspective and the necessary tools to understand the field. Reviews the state of knowledge and developments on wave energy recovery Presents the history of wave energy recovery Classifies the various systems for recovering this type of energy

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