The device is being designed to work in 60 meters water depth and in the fastest flow speeds, where the potential energy capture is greatest. However, as shown in this video, it is scalable to different depths and speeds.
Ocean Flow Energy Ltd were awarded a Shell Springboard Award (for the North of England and Scotland) in 2009.
