Edona Energy Solutions
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.
