tidal power

ok my rival i stated that i have no prove that it the seagen turbine doesn't help the enviorment but i have stated that yes it does the seagen turbine doesn't pollute and tis safe for thee sea life also you can't get your sources from wiki becuase the informatioin isn't right also The installation of SeaGen in Strangford Lough will be carried out by A2SEA A/S of Denmark, one of Europe's leading offshore installation contractors. The SeaGen 1.2MW commercial demonstrator has been developed on the basis of results obtained from SeaFlow, the world's first full-size tidal turbine installed by Marine Current Turbines off Lynmouth Devon in 2003. It has taken the subsequent four years for Marine Current Turbines to design and build SeaGen and secure the necessary environmental and planning consents. SeaGen is a commercial demonstration project with permission to operate in Strangford Lough for a period of up to 5 years. It is intended as the prototype for commercial applications of the technology that will follow. Martin Wright, Managing Director of Marine Current Turbines said: "SeaGen's installation is a very significant milestone for both Marine Current Turbines and the emerging marine energy sector. Following from our previous experience with SeaFlow, our 300kW experimental test system installed in 2003 off the north Devon coast we are confident that SeaGen will show that tidal energy can be truly competitive with other forms of power generation. Decentralized tidal current energy is fundamentally predictable and sustainable. It is also environmentally benign." Commenting on the future prospects for tidal current energy, Martin Wright added: "We will build on the success of SeaGen to develop a commercial tidal farm, of up to 10MW in UK waters, within the next three years. With the right funding and regulatory framework, we believe we can realistically achieve up to 500MW of tidal capacity by 2015 based on this new SeaGen technology." Recognizing the special marine environment of Strangford Lough, MCT has undertaken a comprehensive environmental monitoring programme. This program is already active and is managed by Royal Haskoning, a leading environmental consultancy, working in partnership with Queen's University Belfast and the St Andrews University Sea Mammals Research Unit. The program is overseen by an independent body, chaired by David Erwin, a former Chief Executive of the Ulster Wildlife Trust. The A2SEA jack-up barge, "JUMPING JACK", is planning to mobilize from Belfast's Harland & Wolf shipyard, where SeaGen is already complete and waiting, to Strangford Lough on August 20th. It is expected that the drilling of a single pile into the seabed and the installation of the twin-turbine device will take 14 days, with commissioning and power generation to the local grid shortly afterwards. Martin Huss, Sales & Marketing Director of A2SEA said: "We are delighted to be working with MCT on this important and challenging project and hope it is the start of a long and rewarding relationship as tidal technology enters the market place in the UK." The blades are designed for bi-directional flow, so that they turn regardless of which way the tide is rushing. They'll spin 10 to 20 times per minute. The company says this is slow enough to allow fish and other sea creatures to get out of the way if they're swimming on through. But it certainly doesn't sound like anything a diver would want to approach. This Seagen installation may be just the first step. As part of another project, the company is also hoping to install a farm of underwater turbines off Wales that would be capable of powering thousands of homes. my sorces are from popsci.com and also alternative-energy-news.com
