I do like that the blades on the FFWD are shaped like an airfoil (and therefore unidirectional). I would like it even more if there were some wind tunnel data!
It sounds like the Corima blades are as well: "The profile of the rim with the 2D concept and the shape of the spokes like a drop of water (leading edge and trailing edge) make it very aerodynamic."
