| Quote: | Inside Ireland - 24/11/09
Queen’s University Belfast has launched the world’s largest working hydroelectric wave energy in the Orkney Islands in Scoltand.
Operated by private firm Aquamarine Power and known as the Oyster, it is currently the world’s only hydroelectric wave energy device producing power.

Is that a set of christmas-tree lights hanging from it? Are they in fact closet HouseBlingazz on Orkney??
Interestingly enough they also had the UK's first ever wind turbine...in the 1940s. I saw it at AllEnergy expo a couple of years ago. The blades were made out of "natural carbon fibre" (wood  )

Got the wrong picture there Aurora. That's a tidal flow turbine not a wave energy devise. Wave energy devises work by either bending as the waves go past, as in the Pelamis, or by using the differing height of the water column to pressurise air or a liquid, as I think this one must.
The turbine shown in the picture uses the flow of the water current to turn the turbine as a wind turbine uses the flow of air.
