EWT’s advanced interlocking S-shaped multi-blade design harnesses greater amounts of the wind’s kinetic energy than traditional Savonius designs for conversion to mechanical energy.


The S-shaped design concentrates the wind energy at the inner vortex of the blades whilst the outer shape of the blade reduces trailing edge drag.


The interlocking design of the blades eliminates the need for central shaft providing the following advantages:
Light weight
Increased rigidity and strength
Direct drive low rpm generator
