Wave Country Notes
Wave energy activities in Finland have been mainly undertaken in universities, with a few exceptions, e.g.:
This company has developed the WaveRoller. This consists of a vertical buoyant flap hinged along its bottom edge to a structure on the sea bottom. The flap moves back and forth in the waves, operating a piston pump on the sea bed. This can be used directly to operate a hydraulic motor and generator rated at 13 kW or the output of several flaps can be fed into a common hydraulic circuit to power a central generating system, which can be mounted on the shore. The device has been tested at small scale and at 1/3rd scale in the European Marine Energy Centre (EMEC) in Orkney, Scotland (www.aw-energy.com).
