Edona, new paradigm of wind turbine
Minimum Friction
at Each of the Contact Points
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.
Minimum Requirement of Parts

The structure of Edona turbine is designed in such a way that
movement of the parts does not put undue stress to each component.
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
where buildings are in close proximity to one another.
Edona turbine units installed on top and/or side of the buildings
do not need to turn to face the wind.
They can take advantage of direct wind and crosswind(P= ½ ℓAVᶟ)
and winds enhanced around the building to generate
while absorbing vibration of the building
caused by high wind to stabilize the buildings.
