context_page_description: Unconventional wind turbines are those that differ significantly from the most common types in use.
  As of 2012, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine, where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower. A second major unit type is the vertical-axis wind turbine, with blades extending upwards, supported by a rotating framework.
  Due to the large growth of the wind power industry, many wind turbine designs exist, are in development, or have been proposed. The variety of designs reflects ongoing commercial, technological, and inventive interests in harvesting wind resources more efficiently and in greater volume.
  Some unconventional designs have entered commercial use, while others have only been demonstrated or are only theoretical concepts. Unconventional designs cover a wide gamut of innovations, including different rotor types, basic functionalities, supporting structures and form-factors.
context_section_description: Proposals call for generating power from the energy in the draft created by traffic.
