The conventional Lift type turbines spin faster than wind speed
and they generate frictions in the multiple contact points.
However, Edona's turbine that uses Drag type that does not exert
as much force in the shaft (C) as the Lift type.
Friction on Shaft C is small as it moves with the wind direction
at low speed not requiring a high quality bearing parts.
The structure of Edona turbine is designed in such a way that
movement of the parts does not put undue stress to each
It does not require special parts and the number
of parts required is
significantly less than conventional turbines.
Edona turbine is ideal in a metropolis setting
