Theworld ’s big steer turbineis off the seashore of Scotland . building start in 2012 , with small-arm foregather in the winter of 2013 . Now the image is churning out enough top executive to provide 4,800 place .
The turbine is liberal enough that it make gumption to useelephantsas the basic unit of weight . ( Plus , I ’m bored of pounds , kilograms , and scads . ) Each blade is 83.5 m long , stretching the duration of over a dozen elephant behind - to - torso but weigh in at only three elephants to each one . The nacelle — the piece that houses all the generating constituent — weighs as much as 92 elephants . The whole construction stretch 196 metre above the ocean , the height of 50 to 65 elephant stacked on top of each other ( not accounting for strange postures as they try out balance on each other ’s backs ) .
The super - sized composition meant that all stage of construction and shipping were ridiculous . The blade cap was carefully shipped via barge in very , very calm H2O :
Watching the brand get transported is the part that completely spellbind me . build in Denmark , they had towind their way over field and hill , and even a teentsy bit of ocean , before reaching the installation location in Scotland .
ring it an offshore turbine is a turn of a technicality — the turbine standsbarely 50 meters off the sea-coast . The7MW image turbinereached operational content deep last year , and will bunk for five years as they measure if it lives up to expectations .
As alway , “ large , ” “ cock-a-hoop , ” and all those other superlative depends on exactly what you ’re measuring . The prototype in Scotland has the longest blades of any operational wind turbine , but it ’s beat out for big businessman by an8MW being tested in Osterild , Denmark , and a whole herd of 7.5MW Enercon E126 turbines .
Just how big are these monster turbines compared to the more distinctive 2 to 3 MW turbine that populate wind bailiwick ? An mean 2.5 MW turbine ’s full stretch , the diameter across the entire brass , is littler than the length of a exclusive blade of Scottland ’s 7 MW paradigm .

An earliest variant of this clause , and the preview - schoolbook that bulge up when the article is shared , express that the wind turbine can power 28,000 homes . That was a relict from an early draught dealing with idealized calculation of detrition - free surfaces , steady perfect winds , and other theme that do n’t function in world . While the turbine should produce a stupendous 7 MW , the trial period is measure if the prototype survive up to calculate expectation of enough power for 4,800 home .
