This project evaluated the gains in terms of efficiency, flexibility and robustness of an electro-mechanical PTO system which transforms the bi-directional movement into a uni-directional rotation that can easily be fed to a generator.
View DetailsThis programme is for the research and development of Power Take Off (PTO) technology, a fundamental component of a wave energy converter. The key task of the PTO is to transform the motion from the prime mover, as it reacts with itself or a fixed reaction point, and convert it into a smooth electrical output ready for delivery to the grid.
