Definitions

  • the present invention is directed to wind power systems and in particular to vertical axis wind systems.
  • VAWS Vertical axis wind systems
  • HAWS horizontal axis wind systems
  • One advantage is that the VAWS can harness wind from any direction without having to reorient to such direction such as is required with the HAWS.
  • Another advantage of VAWS is that the blades may be constructed to a much larger scale than HAWS due to the vertical axis orientation. The vertical axis orientation also results in reduced centrifugal stresses on the blade structure. Due to their vertical orientation VAWS also lend themselves to work at higher elevations clear of any obstructions where the wind speeds are higher.
  • the present invention is directed to an improved VAWS and components for such systems.
