More blades means less area for wind to get through and more friction from the blades moving through the wind. I don't have the equation on hand, but if you optimize for efficiency, it comes out at 3 blades. You see two sometimes because it's much more simple to balance. Four blades are just less efficient than three. I dunno about the second, but the reason why wind turbines have three blades has to do with the amount of area taken up by the blades.

Why don't use 4 blades instead of 3? 2. Why do you choose to loose power by rectifying AC power to DC for batteries and transferring it back to DC? Des anyone run wind power straight to their utility meter to run it backwards? If so how do you do it? Joe Washington pilothouse1@comcast.net I have2 questions for all the wind generator guys.
