  1. 1. Valuing the environmental impacts of wind power : a choice experiment approach

    Författare :Kristina Ek; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Sammanfattning : There exists a political goal in Sweden to increase the use of renewable energy, and wind power seems to be a favorable choice from an environmental perspective. Although the public generally expresses a positive attitude towards wind power, specific projects often face resistance from the local population. LÄS MER

  2. 2. Sea Level Compensation System for Wave Energy Converters

    Författare :Valeria Castellucci; Rafael Waters; Ronan Costello; Uppsala universitet; []
    Nyckelord :Ocean energy; Tides; Linear generator; Point absorber; Offshore experiment; Hydro-mechanic modeling; Power absorption; Control system; Communication system; Measurement system; Lysekil research site; Wave Hub.;

    Sammanfattning : The wave energy converter developed at Uppsala University consists of a linear generator at the seabed driven by the motion of a buoy on the water surface. The energy absorbed by the generator is negatively affected by variations of the mean sea level caused by tides, changes in barometric pressure, strong winds, and storm surges. LÄS MER

  3. 3. Swash Processes and Dune Erosion: Emphasis on Vessel-Generated Waves

    Författare :Li Erikson; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marklära; kartografi; klimatologi; Civil engineering; hydraulic engineering; geomorfologi; Fysisk geografi; climatology; cartography; pedology; geomorphology; Naturvetenskap; Physical geography; Natural science; swash; erosion; vessel-generated waves; dunes; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastline changes as a result of exposure to vessel-generated waves has become a topic of increased research.

  4. 4. Experimental results from the Lysekil Wave Power Research Site

    Författare :Olle Svensson; Mats Leijon; Jörgen Blennow; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; Lysekil; Marine Substation; Offshore measurement; strain gauge; lateral force; Invlination and azimuth angles; Wave energy converter; Temperature measurements; Inverter; Energy; Control sustem; CompactRIO; Vågkraft; Mätteknik; Styrsystem; Lysekil; Engineering Science; Teknisk fysik;

    Sammanfattning : This thesis presents how experimental results, from wave power research performed offshore at the Lysekil research site, were obtained. The data were used to verify theoretical models as well as evaluate the feasibility of wave power as a future sustainable energy source. LÄS MER

  5. 5. Experimental Measurement of Lateral Force in a Submerged Single Heaving Buoy Wave Energy Converter

    Författare :Andrej Savin; Mats Leijon; Magnus Karlberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy converter; Tight mooring system; Offshore measurement; Strain gauge; Estimation of stress; Lateral force; Inclination angle; Snatch load; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The search for new solutions for the generation of energy is becoming more and more important for our future. Big arguments and disagreements on e.g. the questions of gas transport or the dependence on energy supplied by other countries raise demands on the development of new forms of alternative energy resources.
