The global climate for the development of waves with potential useful energy together with some data examples is also defined. Fundamentals of wave energy conversion and systems are outlined. This report categorizes both by sketches and description, various methods that have been suggested and in most cases implemented. The text is categorized into the operating location relative to the shore. In some cases certain systems fall into more than one category.
Power take-off systems are an important part of any wave energy conversion system.
It is in this area of consideration that work is being conducted to increase the efficiency and the reliability of wave energy conversion systems. The economics of wave power are also discussed. There are theoretical methods of predicting the economics and also some test data results. However, it is obvious at this stage of this unique technology that, while it is certain that benefits will be derived from its use, the economics of systems cannot be fully defined until further practical operation has taken place. The possible impacts on the environment are also covered.
