Patent ID: 12012928

Abstract:
A vertical-axis wind turbine. The vertical-axis wind turbine comprises a central rotatable hub having multiple wingspars to mount multiple airfoils, a pushrod firmly and rigidly positioned via each wingspar to convert a linear kinetic wind energy from the airfoils to the pushrods to the rotational energy of the central rotatable hub, and an axle attached to the central rotatable hub. The vertical-axis wind turbine rotates the multiple airfoils configured with two airfoils per wingspar, wherein at least two airfoils are mounted on each wingspar. The airfoils work when they are blown upon by applying fluid force to the pushrod and wingspar, one airfoil is blown and held into the maximum angle of attack to perform work to be pushed by the wind, and its opposite is blown and held into the minimum angle of attack to pull back in the wind.
