Revolutionary Tidal Fence Generator

Revolutionary tidal fence generator being developed in the UK, which doesn't harm marine life.
Peter Dixon, Kepler’s chairman, told Reuters news agency: “If we can build up to, say, 10km worth, which is a very extended fence, you’re looking at power outputs of five or six hundred megawatts. And just to visualise that, it’s like one small nuclear reactor’s worth of electricity being generated from the tides in the Bristol Channel.”
