Don't bother, the business will be over by then. But knock up? Did you read of the windmill that lost its top recently off Samsø? Siemens and the windmill owners are arguing about who is to fish the bloody thing out of the water. And have you heard about Horn Reef? Apparently some 90 windmills have to have their tops taken ashore for repair because the wings are loose. Are you still into modelling aerodynamics?
