Next Generation Underwater Turbine

Under water tidal power generation is not a new technology but it is improving day by day recently a group of engineers of oxford developed new design called Transverse Horizontal Axis Water Turbine which they think is more powerful and efficient than resent technology, according to them THAWT's ( Transverse Horizontal Axis Water Turbine ) manufacturing cost is 60% lower and has 40% lower maintenance cost.THAWT uses different technique than recent technology which has works as wind mill underwater, THAWT uses cylindrical rotors that rolls around its long axis with the flow of water. According to the engineer THAWT could produce 12 megawatts of energy which is enough for 12000 homes that recent one.

But even though with their achievement they are concerned of underwater ecology,Steph Merry, head of Renewable energy has told that in there design they have taken full consideration of climate change and the requirement of safeguarding the ecology of tidal areas.[Guardian.co.uk]
