Special Features 2
Innovation for Low Noise
The Airdolphin comes with the "Silent Disrupter Blade". This new blade has a number of thin grooves on its surface, which significantly reduces air flow noise. Our designers were inspired by the wings of owls that enables it to fly silently and unnoticed while approaching its prey.

Power-Assist Function
When there is no wind, the Airdolphin uses previously generated power to rotate for 10 seconds per minute.
This will enable the rotor to start up at a mere 1.5m/s wind, reaching the cut-in point more efficiently. At the same time, the function prevents freezing in cold weather.
Power Generator
 |
A power generator weighing 7.5kg and a maximum 4.5kW power output is used for the Airdolphin, realizing increased power generation and strong regenerating brake performance. The most powerful neodymium iron boron magnet called "NEOMAX" is used. |

Data Communication System
The Zephyr Communication System allows you to connect the Airdolphin to the internet. You can also install an optional GPS receiver to the turbine for confirming each unit's location.
Unique Design - Winner of the Good Design Award 2005
|
Our original body-design with sleek lines and functional beauty was inspired by wild creatures of nature. Airdolphin's form represents harmony with the environment as well as the strong presence of the unit itself. As the name implies, our turbine looks alive, eager and ready to catch the wind. |

Lifecycle Assessment
|
The CO2 emission during Airdolphin's production is roughly 180kg. It only takes 4 to 5 months to offset this amount through power generation by the wind turbine (avg. wind speed 4.5m/s, based on 0.425kg - CO2/kwh). Beyond this offsetting point, the amount of generated power becomes the amount of reduced CO2; thus contributing to the global environment (from Tokyo University Hirao laboratory's research data). |
