Why not only a few large turbines to one large generator?as physics and engineering has proven in many tests beforehand. it is far more efficient to have fewer mechanical parts (being that mechanical parts have a terrable efficiency) the cost per kilowatt actually would rise with the number of parts inbetween the actual blades and the generator itself. (not to mention the increase complexity and maintenence for every extra mechanical part) the reason that the generators are housed in the Nacell at the top of the turbines is to allow the mechanical losses to be at the absolute minimum. efficiency of electricity at a high voltage is a lot better than a mechanical part could ever reach. to a magnitude of up to 70% better.
