Vertical wind turbine

A vertical axis wind turbine apparatus, comprising:

• a fixed turbine axis;
• a plurality of carousal shafts operatively connected to the fixed turbine axis;
• a plurality of carousal plates attached to the plurality of carousal shafts;
• a plurality of turbine blades pivotally attached to the plurality of carousal plates, the plurality of turbine blades comprising:
• one or more first turbine blades to receive wind and one or more second turbine blades that are not exposed to wind, wherein one or more first turbine blades are exposed to a maximum area by stretching away from the fixed turbine axis, and the one or more second turbine blades get folded inside toward the fixed turbine axis;
• an offset shaft assembly configured at a middle part of the fixed turbine axis, wherein the offset shaft assembly comprising:
• a plurality of offset timing shafts suspended to the plurality of carousal shafts, wherein the offset timing shafts is offset from the center of the plurality of carousal plates and floats freely from the respective suspended carousal shaft in order to reduce the aerodynamic drag;
• and
• a plurality of counterweights form a junction between the top carousal shaft and the bottom carousal shaft;
• and
• a plurality of timing and restricting shafts emerge from the offset timing shaft to connect with the plurality of turbine blades, in order to execute the operations of stretching away and folding inside.
