Abstract: A turbine assembly is provided assembly having rotor defines a plurality of recesses disposed about an axis of rotation (Ar). Each of the recesses having a wide end and a narrow end. The recesses are disposed in the alternating orientations such that the wide ends and the narrow ends of the adjacent recesses are proximate to one another to minimize wake turbulence, thereby optimizing efficiency.

Abstract: A wheel assembly is provided that includes a body coupled to the central hub to rotate about the axis of rotation. The body forms an alternating pattern circumscribed about the central hub at constant radial distance from the axis of rotation. The body defines a median circle centered on and transverse to the axis of rotation. The alternating pattern of the body is evenly distributed across the median circle, resulting in an effective width greater than the width of the body. On hard surfaces, the wheel assembly provides a broad track while maintaining a relatively thin contact area, as result providing reduced friction than a traditional wheel. On soft surfaces, the wheel assembly provides substantial traction.
