An improved vertical axis wind turbine for generating electric power which includes blades that provide improved performance per unit of surface area. The blades are adapted to rotate about a vertical axis and are shaped having a leading cupped section joined to a lagging airfoil section. The leading cup section is defined by a cup radius r and the lagging airfoil section is defined by an airfoil chord length C.sub.L. The leading cupped section and lagging airfoil section extend vertically a distance h between terminal bottom and top ends. The cup radius r and chord length C.sub.L both decrease towards the terminal bottom and top ends of the blade. Also, the airfoil section is located a radial distance C.sub.d from the vertical axis and the radial distance C.sub.d decreases towards the terminal bottom and top ends of the blade.

A decorative ornament powered by a vertical axis wind turbine. The turbine includes blades that rotate about a centrally located vertical shaft. An LED illuminated globe is centrally located within the rotating blades and is secured atop the shaft. An alternator is located below the globe and is coupled to the rotating blades. The blades are shaped having a leading cupped section joined to a lagging airfoil section. The leading cup section is defined by a cup radius r and the lagging airfoil section is defined by an airfoil chord length CL. The cup radius r and chord length CL both decrease towards the terminal bottom and top ends of the blade. Also, the airfoil section is located a radial distance Cd from the vertical axis and the radial distance Cd decreases towards the terminal bottom and top ends of the blade.

The invention is a generator that will recharge its internal storage from as low as a five mile-per-hour wind without typical speed multiplying methods such as gears and pulleys. The invention creates alternating currents from rotating magnets by aligning the polarity of each magnet face in the same direction and wiring opposing sets of coils in series as a single phase. These series-connected sets are wired out-of-phase with each other to produce alternating currents. When mounted in a breezy location, the invention will silently provide reliable and consistent energy to power its internal devices.
