(Before It's News)

Weptos, a Danish wave energy startup and the developer of floating Wave Energy Converters (WEC), has opened a new research and development center in Fredericia, Denmark.

Opened in August 2012, the new production facility is Weptos’ new center for the development and design of its first commercial wave energy plants.

“Anchored to the seabed, the Weptos system is built up of a number (~20) of asymmetric rotors that move independently, the rotors are connected to a single axle, which drives a generator. The many rotors using the same axle, makes the generator rotating movement uninterrupted. Under normal operating conditions the rate of axle turn is about 20 to 40 rpm. A possible generator solution could therefore be existing technology from commonly used wind turbines. The span of the system is flexible so that the capacity is optimized at all conditions; in a calm sea the span is wide, in high seas the span is narrowed — this also reduces the stress of the structure.”
