From 'The Engineer' of 11th January '10 comes this story by Siobham Wagner entitled 'Humber rides the Wave' of a demonstration of a new tidal-energy machine called 'Neptune Proteus NP1000' soon to be deployed in the Humber Estuary.
Proteus is a moored device built with a square-turbine cross section designed to work in shallow waters. It has patented flow-control shutters to maximise the area of water hitting the turbines, thus increasing torque and power output, designed to function efficiently, generating 30% more electricity per unit channel than circular turbines, generating at least 1,000MW total.
