Claims18
A spinning device, comprising:
- a wind blade assembly including a generally hollow body supporting a plurality of blades;
- a rod configured to support the wind blade assembly;
- and
- a magnetic levitation assembly configured to support the rod,
- wherein the hollow body comprises an upper wall and a side wall extending downwards from the upper wall and defining a hollow enclosure between a bottom surface of the upper wall and an inner surface of the side wall,
- wherein the rod is coupled to a center of the upper wall to provide a rotational axis for the wind blade assembly,
- wherein the plurality of blades are coupled to an outer surface of the side wall and are configured to cause the hollow body to spin via a torquing force applied to the blades,
- wherein the magnetic levitation assembly comprises an upper magnet coupled to the rod below the upper wall,
- wherein the magnetic levitation assembly further comprises a lower magnet positioned below the upper magnet in repelling polarity to the upper magnet, the magnetic levitation assembly being configured to levitate the rod and wind blade assembly via a repelling force between the upper magnet and the lower magnet.
