The Edona turbine which uses the Drag type that does not exert
as much force in the shaft (C). The friction on the shaft is
small because it moves with the direction of the wind at low speed,
especially with the minimal resistance of the returning blades (on C').
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.
