• Technological Advantages
    • Utilization of wind and sun energy in one element – a unique, beautiful design
    • Uniform energy generation throughout the year (during winter time more wind, during summer time more sun)
    • Totally soundless (no sounds besides the wind) due to the spiral shape and the rotation speed does not exceed the wind speed.
    • The device is safe for people, animals and nature.
    • Uses winds from all directions, even turbulent winds (a propeller turbine has to be turned into the wind and shut down above 45 mph)
    • Works with gentle summer breezes and in violent storms
    • Rotates at the same speed as wind velocity; stays balanced with self-regulating stability
    • No oil leakages, no ice build-ups, no vulnerable rotor blades or propellers
    • Solar cell surface has a Dendrite system absorbing the sun light from all angles; producing more yield from the sun to offset the times when cells do not point toward the sun while rotating
    • Solar cells are parallel-connected producing low losses, and providing secure and reliable electrical connections
    • Solar cells are cooled by the rotation, maintaining electrical generation efficiency
    • Contact-free current flows from the rotation of the wind vanes into the generator – no gears are needed
  • Production Advantages
    • Stacked, segmented, identical sections (uniform production) are pre-formed and stacked to assemble the turbine
    • By segmenting, lower costs are achieved for tools, mounting and final assembly
    • Segmenting molds allows for adjustment of the turbine to scale the output requirements with different sizes
    • Starts charging with very low wind speeds; as low as 4 mph.
    • No shutdown is necessary during heavy storms; highest RPMs yield highest electricity output
    • Produces about 50% more electricity than traditional horizontal propeller turbines, higher yield from both low and high wind speeds and from the solar cells
  • Cost Advantages
    • Lower maintenance cost
      • The generator is contained in the base on the ground: easy maintenance, system monitoring, and replacement of all parts
    • Lower repair cost
      • No repairs or replacements at tall heights, compared to traditional turbines where propellers and generators are mounted on tall towers
    • Lower installation cost
      • Included Hydraulic up-righting of the turbine from the ground, no cranes needed
      • No operating or fuel costs as both the solar radiation and the winds are provided by Nature
    • Lower insurance cost
      • All moving system elements are on or near the ground
      • No risk of breaking propeller blades
