Is It Intuitive to Strike a Thick Blade?

The bigger the less like a knife that turbine blade is the more surface area that that force is distributed over. The shape of the blade has enabled you to maintain kind of the orthogonal component of that force, regardless of the speed of the blade which increases as you get further from the center of the turbine. We've been able to create turbine blades that have these very odd looking leading edge shapes but the resulting turbines are well over 90% efficiency. In some cases now predicted to exceed 92% or even greater efficiency.
