A WAVE POWER UNIT, A BUOY, USE OF A WAVE POWER UNIT AND A METHOD FOR PRODUCING ELECTRIC ENERGY

摘要

A wave power unit including a buoy, adapted to float on a water surface (2), and a electric generator is connected to the buoy through connection means (4, 12, 13). The buoy when floating on a water surface (2) and when seen in a direction perpendicular to the water surface has the shape of a closed loop enclosing a inner opening substantially free of elements related to the wave power unit.
