"WebLift type wind turbines can experience TSR as high as 6. This is possible because the natural wind is vector summed with the wind opposing the forward velocity of the airfoil. This combined velocity is known as the relative wind. HOW TURBINES WORK The wind imposes two driving forces on the blades of a turbine; lift and drag. " - Darrieus wind turbine working principle
