Increasing any vertical axis wind turbines efficiency

A vertical axis wind turbine with a shield comprising:

• a. a center pole with a bearing at a top of a center pole and a supporting base at a bottom which the center pole stand on, the center pole and the supporting base does not rotate,
• b. on the top of the center pole is a blades section and on a bottom is the generator section of the wind turbine,
• c. in front of the wind turbine blade section, a shield which is symmetric on a horizontal axis, which when viewing the wind turbine system from the top, is placed, wherein the shield height is equal to or more than a blades height, in a way that the shield covers ¾ of the front of the wind turbine blade section from the wind except the blade open facing the wind,
• d. the horizontal axis is horizontal spaced from the cent pole, horizontal axis comprising a horizontal pole that connects the shield with the center pole,
• e. a distance between the horizontal pole and the center pole is equal to ¼ the diameter of the blade section of the wind turbine or ½ of a distance between the center of a blade of a blade section and the center of the center pole,
• f. the shield is coupled to vertical poles and a horizontal poles at a top of the shield, the horizontal pole is indirectly coupled to a the very top bearing via another rod to make up for the offset distance between the center pole and the horizontal poles,
• g. the shield is also coupled to vertical and horizontal poles at the bottom, the bottom horizontal pole is also indirectly coupled to a bearing on the center pole which is below the generator via a rod to making up for the offset distance between the bottom horizontal pole of the shield and the center pole,
