Further technologies to convert wave energy
Oyster systems
A kind of a flap is teathered in intermediate water (~ 10 meter in depth) and is
connected via a subsea pipeline to an onshore hydroelectricity generating plant. A
315 kW oyster system operates in Scotland since 2009. The plan is to build up a
2.3 MW system with three linked systems. The deployment started in 2011.

Power buoys
Power buoys are a modular system with good economies of scale. Converting
mechanical energy by vertical movement into electrical energy. A small module
with low maintanance costs. Livetime is expected to be thirty years and more.
The movement of power buoys caused by waves looks like the movement of
valves in a motor block.
