> Much more visually pleasing than a traditional wind turbine.
But also much larger. It's an inescapable fact that wind energy is proportional to the area captured. So these would have to be as tall and wide as turbine blades.
Except it would be a massive structure, not just a small thin blade on a pole.
And don't think they could get away with flimsy walls either - the pressure of the wind on this thing is the same as the pressure on a regular turbine.
I suspect this last point will sink this project except perhaps in zones with very light wind that can benefit from it's ability to generate with low wind speed (and low pressure, so a weaker structure).
