Abstract: 

The Kobold is a hydraulic vertical axis turbine with free oscillating blades, patented in 1998 by the Italian company Ponte di Archimede International S.p.A. The architecture of the Kobold turbine was inspired by the Voith-Schneider marine propellers. Its main characteristics are:

  • Rotation direction independent of current direction.
  • High starting torque, thus self starting.
  • Flexible layout: floating or base-mounted.
  • High efficiency.
  • Reliable, sturdy and simple.
  • Self adjusting blades.
  • No moving mechanisms.
