Electricity from Wave and Tide: An Introduction to Marine Energy


Electricity from Wave and Tide: An Introduction to Marine Energy Cover


Synopses & Reviews

Publisher Comments:

A concise yet technically authoritative overview of modern marine energy devices with the goal of sustainable electricity generation

With 165 full-colour illustrations and photographs of devices at an advanced stage, the book provides inspiring case studies of today’s most promising marine energy devices and developments, including full-scale grid-connected prototypes tested in sea conditions. It also covers the European Marine Energy Centre (EMEC) in Orkney, Scotland, where many of the devices are assessed. 

Topics discussed:

  • global resources – drawing energy from the world’s waves and tides
  • history of wave and tidal stream systems
  • theoretical background to modern developments
  • conversion of marine energy into grid electricity
  • modern wave energy converters and tidal stream energy converters 

This book is aimed at a wide readership including professionals, policy makers and employees in the energy sector needing an introduction to marine energy. Its descriptive style and technical level will also appeal to students of renewable energy, and the growing number of people who wish to understand how marine devices can contribute to carbon-free electricity generation in the 21st century.

About the Author

Dr Paul A. Lynn, Consultant, UK

Paul Lynn was Founding Managing Editor of the successful and highly prestigious Wiley journal, Progress in Photovoltaics,from 1993 until 2006. He was formally Assistant Lecturer at Imperial College London and Lecturer and Reader in Electrical and Electronic Engineering at the University of Bristol from 1969 until 1984.

As a retired academic, Paul Lynn’s continued interest in renewable energy includes designing and building solar-powered boats. He designed and constructed the catamaran that completed the first ever solar-powered voyage along the non-Tidal Thames in 2003. He was awarded 1st and 2nd prizes in the Sustainable Transport section at the Royal Bath & West show in 2008 for two more recent solar catamarans.

Paul Lynn has written six technical books to date and is author of over 50 technical papers and articles.
