However, the E-112 is indeed rather big - it was the first built of the 5-MW class, intended mainly for off-shore farms. Currently, this class has two other (also German) entrants: the Multibrid M-5000 and the REpower 5M, both rated at exactly 5 MW. Industry leader Vestas is also developing such a machine, the V120, for 4.5 MW.
Actually, these numbers wouldn't look that dramatic if one remembers that single 3-4 MW test units were built in the eighties and early nineties in Germany, the USA and Sweden. However, those had many serious problems - for example Germany's GROVIAN was heavily damaged by a storm. But for example the first E-112 (which I pictured) runs without major problems for three and a half years now. *Lunatic*, n. One whose delusions are out of fashion.
