Maximum Efficiency with Minimum Resistance |

 |

 |
||||||
Maximum power output at nominal wind speed enough for daily power consumption |

Savonius type Edona Turbine |
||||||
Close to zero wind resistance to the returning blade. |
||||||
Maximum Use of Torque |
||||||
 |
||||||
Savonius type Edona Turbine |
||||||
The farther the blade is from the central axis, the greater the torque |
||||||
Comparison of minimum wind speed |

||||||
 |
||||||
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. |
||||||
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 |
||||||
 |
||||||
 |
||||||
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 |
