Wave-energy

over a larger range of the wave spectrum. Incoming waves stimulates resonance at a longer coupling length. Multi-resonance Oscillating water column 22 A 600 kW Wells turbine was build up at a Norwegian island. Two severe storms destroyed these installation. 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.

Converting mechanical energy by vertical movement into electrical energy
