  3. 3. Wave Power for Desalination

    Författare :Jennifer Leijon; Cecilia Boström; Irina Temiz; Jens Engström; Deborah Greaves; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : This doctoral dissertation is concerned with the complex dynamics of knowledge in the South Korean film and TV industry and Swedish filmmaking from a spatiotemporal perspective. The film and TV industries are highly dependent on knowledge and innovation. LÄS MER

  5. 5. Cooling Strategies for Wave Power Conversion Systems

    Författare :Antoine Baudoin; Cecilia Boström; Anne Blavette; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; power conversion system; thermal management; power elctronics; passive cooling; natural convection.;

    Sammanfattning : The Division for Electricity of Uppsala University is developing a wave power concept. The energy of the ocean waves is harvested with wave energy converters, consisting of one buoy and one linear generator. The units are connected in a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. LÄS MER
