Atlanta, Georgia [RenewableEnergyAccess.com] Clipper Windpower has announced that is has chosen Blyth, Northumberland in the United Kingdom as the site for the development of its new offshore wind turbines.

"We established the Project in support of the U.K. Government's ambitious plans to generate more than 20% of the country's electricity from renewable sources. This is both a responsible and necessary endeavor considering growing worldwide concerns over global warming and climate change."

--James Dehlsen, Chairman and CEO, Clipper Windpower

Called the Britannia Project, the $65 million development program will develop a 7.5 MW wind turbine using Clipper's technology. North England's Centre of Excellence for New and Renewable Energy will provide engineering, testing and development services in support of the project.

"We established the project in support of the U.K. Government's ambitious plans to generate more than 20% of the country's electricity from renewable sources," said James Dehlsen, chairman and CEO of Clipper. "This is both a responsible and necessary endeavor considering growing worldwide concerns over global warming and climate change."

<p>As turbines get larger, the tip speed of the blade does tend to get higher all other things being equal, even while the number of revolutions per minute is reduced. In order to get around this, the blade aerodynamic profile changes slightly to run optimally at a lower angular velocity i.e. more torque rather than more speed. I am not sure how far this process can be taken, but I know we havn't reached the technological limits yet. Of greater concern is the tendancy for blade weight to vary with the cube of length while output varies with the square.</p><p>LMglasfiber has plans to scale up turbine blades to the 80-90 meter per blade range using primarily glass fibre. This would serve 8-12 Mw turbines.</p>

there is little further info about the projected 7.5MW turbine which would be HUGE! I thought there was a limit to the size due to the speed of the blade tips approaching the speed of sound... can anyone say any more about this?

A machine with 90 meter blades would be truly huge. What would be the likely swept diameter and the height to the hub? Also, how far apart do these machines have to be, laterally and one-behind -the -other? The spacings I have observed on exisiting wind farms in Northern England seem uneceesarily large. How are they determined?
