Construction
This offshore wind farm cost more than £300m and was built in depths of up to 18 metres (59 ft) of water, in less than two years. The foundations used are monopiles of 4.7m diameter installed by drive penetration using a hydraulic hammer. The foundations were driven to depth of around 22m below the seabed before a transition piece was installed on top of the pile and secured in place using a grouted bond. The wind turbine and its supporting tower was then installed onto a flange attached onto the transition piece and secured by bolts. The blades were made in Denmark from balsa wood and fibreglass.
As of January 2009, Britain is the world's leading generator of offshore wind power, followed by Denmark.

“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
—T.S. (Thomas Stearns)
