Abstract
The power generation by sea waves is one of the important engineering problems to be realized in Japan in the near future which has depended heavily on imported fossil fuels as energy source. This study assess qualitatively the environmental effects of power generation for different systems presently proposed which are operated at three locations, namely at land, nearshore and offshore. Six systems are studied from which the moving body in chamber at nearshore area is found prospective from both the environmental effects and the conflict with other industries.
