Written by two well-known and respected engineers, this exciting new volume is the most up-to-date and comprehensive text on power generation from waves and water currents available today to engineers, scientists, and students, also covering the latest advances in wind power generation.

As the world turns further and further away from fossil fuel energy sources, unconventional and renewable sources of energy, such as power generation from water sources and wind energy, are becoming more and more important. Hydropower has been around for decades, but this book suggests new methods that are more cost-effective and less intrusive to the environment for creating power sources from rivers, the tides, and other sources of water. Written by two experts in the field, it also covers wind energy and how it can be more efficiently harnessed.

This groundbreaking new volume deals with modern problems of using wind energy, namely, jet currents in the atmosphere and the energy of water flows of rivers, ocean and sea currents, including those caused by tides. Wind and water-based energy sources form an essential part of the renewable energy solution. The engineering measures discussed in this book prove, for example, that by reducing the rate of dissipation of atmospheric surface low-level currents by only one percent, it is possible to provide all of humanity with energy at rates twice the per capita consumption of the wealthiest countries. Whether for the veteran engineer or the engineering student, this book is a must-have for any library.

Wave, Wind and Current Power Generation:Is one of the first books available on wave and current power generation containing information for engineers to use for solving day-to-day problemsAssists engineers in rapidly analyzing problems and finding effective design methods and select mechanical specificationsProvides methods and proven fundamentals of process design for practical applicationHelps achieve optimum operations and process conditions and shows how to translate design fundamentals into mechanical equipment specificationsCovers not just wave and current power generation, but also has a section on wind power generation and a comprehensive overview of renewable energy in the world today

Victor M. Lyatkher, PhD, is a professor, engineer, and inventor. He was educated in Moscow and Leningrad and has developed and patented numerous processes and machines. These deal mainly with renewable energy sources such as tidal power, water turbines, and vertical axis wind turbines. He developed a new method to forecast long-term variations in the Caspian Sea level and designed a new kind of low head turbine. Mr. Lyatkher has worked for over 35 years in the wind and hydro-power industry. He has received several prizes and awards for his accomplishments, including the Prize of the Council of Ministers of the USSR, the Award of the Indian Society of Earthquake Technology, and five medals of the All-Union USSR Exhibition, gold, silver and bronze. He has published numerous books in English, Russian, and German, and he has over 80 patents to his credit. In addition, he invented the helical turbine, patented in the USSR in 1983 and has authored over 200 technical articles.

Ziaur Rahman is an inventor and an entrepreneur, recognized for his work in the fields of engineering, computer science and information technology. Though he is more known for his achievements in biometric software, one of Ziaurs areas of interest is turbine technology. Since 2015 Rahman has been working with Victor Lyatkher on orthogonal turbines, developing and improving their prototypes. He is also an owner of various patents in the field of turbine design. He graduated with First Class Honors in Electrical and Electronics Engineering from the Bangladesh University of Engineering and Technology. Ziaur holds an MBA degree from the University of Chicago Booth School of Business.
