C-Power StingRAY
The floats and spar independently react to the shape of the passing ocean wave. Each float is directly coupled by a drive shaft to its own rotary generator. The two generators are located inside the nacelle near the top of the vertical spars. As each float rotates, so does the generator, which creates electricity.
