A enclosed vertical axis fluid rotor used as a wind turbine of two designs having multiple sails that are concave on the inside and convex on the outer side which allows omni-directional wind or other fluids to engage sails to create optimum fluid momentum. These are sectional segmentation of each rotor that can be stacked upon one another at locating lug points to be attached to each rotor to keep radial alignment precise during assembly. The preferred embodiment would be of composite materials or plastics that can be molded to a given design of three or more stages. The advantage of this turbine is using the fluids to their optimum efficiency. These designs have low starting speed, low precession, and low drag. One design has a central axis that turns with bearings with the rotor and the other design is a central static (non-turning) axis shaft that allows the turbine to turn on bearings.
