And what about the amount of material required for this huge thin sheet accumulation? It may perhaps serve as a work-of-art, but watch out for the forces on this monstrous apparatus if the control mechanism fails to turn it into the wind.
It is not easy for non polluting wind energy to penetrate the political egg heads, let alone the competitive energy market where it has to push aside traditional power technologies. And the task is not made any easier by a utility promoting such an incredible "radical design" solution. It is far more likely that such a project will damage the reputation of wind energy conversion.
P.S. I am a disciple of the legendary Professor Dr. Ulrich Hütter, the late Pope of wind energy.
