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. |
