1. 1. Studies of a Vertical Axis Turbine for Marine Current Energy Conversion : Electrical system and turbine performance

   Författare :Johan Forslund; Karin Thomas; Cameron Johnstone; Uppsala universitet; []
   Nyckelord :Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : Ocean energy is a field of growing interest when it comes to renewable energy thanks to its high density of energy per unit area, and to the high predictability. Conversion of hydrokinetic energy, found in marine currents, is the utilization of the energy in free-flowing water for conversion to electric energy. LÄS MER
