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. ## Claims ### Claim 1 A decorative ornament comprising: a vertical axis wind turbine comprising a plurality of blades adapted to rotate about a centrally located vertical shaft; wherein the vertical shaft comprises a top terminal end; a light emitting device secured to and located above the shaft top terminal end and within the rotating turbine blades; an alternator coupled to the blades and adapted to produce electric power for powering the light emitting device; wherein each of the blades comprise: a leading cupped section joined to a lagging airfoil section, wherein the leading cup section is defined by a cup radius r and the lagging airfoil section is defined by an airfoil chord length CL; wherein the leading cupped section and lagging airfoil section extend vertically a distance h between terminal bottom and top ends; and, wherein the cup radius r and chord length CL both decrease towards the terminal bottom and top ends of the blade. ### Claim 2 (depends on 1) The decorative ornament of claim 1 wherein the alternator is located within the rotating turbine blades and comprises: a rotor rotatably coupled to the shaft; wherein the blades are secured to and rotatably drive the rotor about the shaft; a plurality of magnets secured to the rotor; a stator fixedly secured to the shaft; a plurality of coils of wire secured to the stator; and, when the rotor is rotably driven, the magnets travel adjacent and induce electric current in the coils of wire. ### Claim 3 (depends on 1) The decorative ornament of claim 1 wherein the vertical shaft comprises a bottom terminal end selectively attachable to a top terminal end of a ground mounting stake. ### Claim 4 (depends on 1) The decorative ornament of claim 1 further comprising a translucent enclosure located above the shaft top terminal end and within the rotating turbine blades and wherein light emitted by the light emitting device is directed within the enclosure. ### Claim 5 (depends on 1) The decorative ornament of claim 1 further comprising a translucent globe enclosure located above the shaft top terminal end and within the rotating turbine blades and wherein the light emitting device is located within the globe enclosure. ### Claim 6 (depends on 1) The decorative ornament of claim 1 further comprising an electric power storage device operatively connected to the alternator and the light emitting device. ### Claim 7 (depends on 1) The decorative ornament of claim 1 wherein the blades extend vertically between terminal bottom and top ends and the blades are secured to a rotor at a vertical midpoint between the terminal bottom and top ends. ### Claim 8 (depends on 1) The decorative ornament of claim 1 wherein the blades are secured to each other at a terminal bottom end thereof. ### Claim 9 (depends on 1) The decorative ornament of claim 1 wherein the blades are coupled to a rotor of the alternator, wherein the blades are attached to the rotor below a vertical midpoint between bottom and top terminal ends of the blades and wherein the blades are secured to each other at their bottom terminal end. ### Claim 10 (depends on 1) The decorative ornament of claim 1 wherein the cup radius r and chord length CL both decrease towards the terminal bottom and top ends of the blade starting form a vertical midpoint between the terminal bottom and top ends. ### Claim 11 (depends on 1) The decorative ornament of claim 1 wherein the airfoil section is located a radial distance Cd from the vertical axis and wherein the radial distance Cd decreases towards the terminal bottom and top ends of the blade starting form a vertical midpoint between the terminal bottom and top ends. ### Claim 12 (depends on 1) The decorative ornament of claim 1 wherein the airfoil section is located a radial distance Cd from the vertical axis and wherein the radial distance Cd decreases towards the terminal bottom and top ends of the blade. ### Claim 13 (depends on 1) The vertical axis wind turbine of claim 1 wherein the blades are formed of sheet material. ### Claim 14 (depends on 1) The vertical axis wind turbine of claim 1 wherein the alternator is selectively connectable to an electric power storage device through a load switch and further wherein, when an output of the alternator is insufficient to produce useful power, the electric power storage device is disconnected from the alternator and, after the blades and alternator gain momentum, the electric power storage device is again connected to the alternator. ### Claim 15 (depends on 1) The vertical axis wind turbine of claim 1 wherein the blades are coupled to an alternator adapted to produce electric power and the alternator is selectively connectable to a battery wherein, when the wind speed is too low to produce enough power to charge the battery, the load is disconnected from the alternator and the blades are allowed to spin freely. ### Claim 16 (depends on 2) The decorative ornament of claim 2 wherein the rotor comprises upper and lower magnet holders whereat the plurality of magnets are secured and the stator is sandwiched between the upper and lower magnet holders. ### Claim 17 (depends on 12) The vertical axis wind turbine of claim 12 wherein the leading cupped section extends between an outermost edge and an inner area, wherein the inner area is joined with the airfoil section and the outermost edge traverses along an arcuate path defined by a diameter D as the blades rotate about the vertical axis. ### Claim 18 (depends on 12) The vertical axis wind turbine of claim 12 wherein the blades are formed of sheet material. ### Claim 19 (depends on 17) The vertical axis wind turbine of claim 17 wherein r/D
