Building a single windmill prototype like that and sticking it alone in the ocean (with a 10 kilometer power cable) is bound to be lot more expensive per MW than building a whole farm of them. The original article also does not specify how much of that money went into development and how much went to actually building the turbine. The cost should come down quite significantly if that thing actually works as advertized and they start building them by dozens.

The fact he's suing in the first place shows he simply doesn't understand the principles behind Wikipedia, so it's faily impossible for him to realize that.
