New Tidal-Energy Testbed Launched In Devon

JaJ_D writes " According to the Beeb, Lynmonth in North Devon (in the south west of the UK) have just launched a new tidal energy generating system. The system is different to others by having the rotor blades fully under water and turning at about 20 rpm (so no harm to the fish). Each '...single 11 metre-long rotor blade will be capable of producing 300 kilowatts of electricity and will be a test-bed for further tidal turbines' Clean, relatively cheap and very little damage to the environment either by discharges or damage to the views. I wonder how many more will be made."
