Turbine Blade

thingiverse

Blades that harness wind power efficiently rely heavily on their precise curvature, which helps them slice through air like a hot knife through butter and maximizes the kinetic energy they capture. When winds of varying velocities hit these blades at multiple points, engineers optimize each part to guarantee that it spins freely without experiencing too much drag, enabling smooth rotation as intended by the original designers who envisioned such structures generating electrical power long ago
