Abstract
A fan assembly can be used under different indoor and outdoor environmental conditions. One or more blades can be attached to an upper bearing assembly and a lower bearing assembly around a central stem. The shape and configuration of the blades can further impart the fan assembly with a 3-dimensional appearance that responds to wind or other air flow, causing a spinning effect. The rigidity of the central stem, as well as components of the blade ensure that the fan assembly maintains the 3-dimensional shape even under high wind or air flow conditions.

A fan assembly comprising:
- a central stem comprising
- a shaft assembly with a proximal end and a distal end,
- an upper bearing assembly operably connected to the shaft assembly, and
- a lower bearing assembly operably connected to the shaft assembly and proximal to the upper bearing assembly;
- at least one blade assembly comprising
- a spine with a proximal tip operably connected to the lower bearing assembly and a distal tip operably connected to the upper bearing assembly,
- a wing having an inside edge and an outside edge, where the inside edge is operably connected to the spine,
- a wing support covering at least a portion of the outside edge of the wing, such that the at least one blade spins around the shaft assembly.
