III. Vertical Axis Drag Turbines (Savonius S-Type / Cup Rotor)

Driven by the differential aerodynamic drag between concave and convex surfaces. Delivers immense starting torque (rotates with a gentle blow), but tip speed ratio is strictly limited ($\lambda < 1$). Overall aerodynamic efficiency ($C_p \approx 0.12$) is lower, making it ideal for micro-power sensors and light poles.
