New Paradigm of Wind Power

Unleashing Limitless Renewable Energy

through Simple and Innovative Design

Generating clean energy

using our innovative wind turbine

Our patented guide track design

maximizes wind to power conversion
Maximum Efficiency

with Minimum Resistance

Maximum power output at nominal wind speed

enough for daily power consumption

Maximum Use of V - V0 Wind

Close to zero wind resistance

to the returning blade.

Maximum Use of Torque

The farther the blade is from the central axis,

the greater the torque


Comparison of minimum wind speed
to generate power (cut-in speed)
between Conventional and Edona Turbine


Average wind speed in New York City

Central Park 1984 - 2018


The external surface areas of buildings increase the wind collection area

for Edona turbines installed on buildings which can potentially convert

wind into power proportional to the cube of the wind velocity.

This advantage along with near zero resistance of Edona turbines can lower

the cut-in speed to as low as 1 m/sec and makes it possible to generate power

continuously even in cities with low average wind speed.

Average Wind Speed in Other Cities
Comparison of maximum wind speed
to operate safely (cut-out speed)
between Conventional and Edona Turbine

Edona Turbine's sails spin at a lower speed than the wind speed and

its multi-axis support design allows safe operation of the turbine

at high speed with minimum noise level.

Conventional wind turbines have a cut-out speed of 25 m/s

and their power generation reaches ceiling at 14 m/s of wind speed known

as 'rated output'. Edona Turbines can potentially generate power

up to 30 m/s of cut-out speed theoretically without 'rated output' limit.

Wind Power

on Commercial and Residential Buildings

with Minimum Noise

Edona Building Integrated Turbine can be attached to buildings

horizontally or vertically without pole support

taking advantage of wind tunnel effect

to generate sustainable power to buildings

while minimizing vibration of buildings during high wind condition



Buildings naturally increase the wind collection area for Edona Turbines

thereby increasing the effective wind speed for Edona Turbine

more than 3 times the actual wind speed which makes it possible for

continuous self-sufficient power generation for the entire building

without interruption even in cities with low average wind speed.

Flexible Design without Pole Support

Edona Turbines are flexible and scalable. 

Sizes and dimensions can be flexible. 

Multiple units can be stacked on top of each other

without pole or tower support.

Source of Stability

Unlike conventional turbines that have central axis of blade rotation,

Edona Turbines do not have central axis

which can be the biggest source of stability problem.

Edona Turbine's structural design is comparable to aircraft in motion.

If an aircraft is tied down to a fixed point on the ground,

wind can damage its structure. However, if the aircraft is in motion,

wind or turbulence will not damage its structural integrity.


Simple and Robust Design

by Multi-Axis Support

Minimum Friction at Each of the Contact Points

Each axis of the blade can withstand extremely high wind

at Natural Wind Environment and produce power

up to Edona Turbine's theretical cut-out speed of 30 m/s

Easy Installation

and Low-Maintenance

Edona Turbine's simple design lends itself

to minimum installation and maintenance cost.

Maintenance could be just as easy as replacing the modules
