The main thing that keeps you from pulling more energy out of the wind is that after a point the air starts to move around the blades, spilling over the tips of the blades, so a ring like that is going to help "trap" that wind, the more you can keep that high pressure air from spilling over the tips of the blades the more force the blades are going to see and the back side of the blades is going to see a lower the pressure.
but my point early on was, if we just make the turbine a little bigger we also see a big jump in power output because you are collecting more energy from a larger area and however you look at it, the generator at the hub is going to have to increase in size at some point as well.
