Vertical axis wind turbines are an intriguing technology that most people still know little about. The turbines we are accustomed to use blades to turn a horizontal axis (which is often housed in the little cupola on the top of the turbine's tall stem).

About a year ago I saw an article about a company from New Mexico who had developed a helix wind turbine which had solar panels in the helix, doubling the efficiency of the turbine.
Sorry I don't have further details or a link.
