if i will use barnoulli's principle which says that fluid flows from higher to lower pressure area

so in case of wind mill if we be able to give a shape in front of the blades so that wind can flow from higher to lower pressure then speed will automatically increase and hence the efficency this shape will be like dome type above the blades or few stages in front of the blades

this method is used a lot in the ancient arctecture mostly in the rooms where the ceiling was not flat but was like in dome shape this gives a better wind in the rooms than the outer environment please give commments over this idea
