The rotor subsystem represents one of the major cost drivers in conventional wind energy systems. Despite the fact that the two vortex extraction systems evaluated have the potential for substantially reducing rotor costs, these cost savings are more than offset by the additional costs required for the augmentation devices. Based on a preliminary analysis of the presently envisioned conceptual designs of the Tornado Wind Energy System and the Vortex Augmentor System, it does not appear that either system could achieve economic parity with conventional horizontal axis wind systems even if all of the technical uncertainties surrounding these innovative concepts are favorably resolved.
