Tidal Energy device being developed in the UK. This video shows a tenth scale version of the device, which has been operating in Strangford Lough for the past year (June 2008 to July 2009).
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.
