    Abstract : Different wave power technologies are in development around the world in different stages of prototype testing. So far only a few devices have been deployed offshore at full scale for extended periods of time. Little data is published about how these different devices perform. READ MORE

  5. 5. Electric Energy Conversion Systems Wave Energy and Hydropower

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karin Thorburn; Uppsala universitet.; [2006]
    Keywords : Engineering physics; Ocean wave power; renewable energy; linear generator; farm simulation; Teknisk fysik;

    Abstract : Electric energy conversion is an important issue in today's society as our daily lives largely depend on the supplies of energy. Two energy sources are studied for conversion in the present thesis, ocean waves and hydropower. The work focuses on the generator and the transmission of its output to the electric grid. READ MORE
