A method and a wave-power aggregate to extract energy from wave motion in a fluid and the use of a wave-power aggregate

摘要

The wave-power aggregate (10) has container (14) which is provided in fluid (12) and equipped with inflow (16) and outflow (18). The container is provided with extension in extension direction between inflow and outflow. The container is provided with first and second portions (20,22). The first and second portions are configured to arrange in first and second positions when under the influence of wave motion. The first and second positions are corresponding to different potential energy.
