A rotor system for a fluid-flow turbine comprising a hub mounted on a shaft, a plurality of rotor blades, and a tension wheel, the tension wheel comprising a rim structure mounted to the hub by a plurality of spokes. Each rotor blade is attached to the rim structure of the tension wheel. The lost energy in the area of the rotor circumscribed by the tension wheel rim structure is captured by applying airfoils, such as blades or sails, to the spokes of the tension wheel and/or an inner section of the rotor blades.
