5. 3. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator

   Author : Oskar Danielsson; Mats Leijon; Göran Engdahl; Uppsala universitet; []
   Keywords : Engineering physics; Finite element method; linear synchronous generator; longitudinal end effect; permanent magnet; point absorber; offshore testing; wave power; Teknisk fysik;

   Abstract : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. READ MORE

6. 4. Wave Power for Desalination

   Author : Jennifer Leijon; Cecilia Boström; Irina Temiz; Jens Engström; Deborah Greaves; Uppsala universitet; []
   Keywords : Wave power; desalination; freshwater; engineering education; linear generator; wave energy converter; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Abstract : This doctoral thesis presents work related to wave powered desalination. Wave power for desalination could be an interesting alternative for islands or coastal regions facing freshwater shortage, and several systems have been proposed in literature. However, desalination is a process which demands a lot of energy. READ MORE
