Air Dolphin

  • In Japan, the biggest difficulty in introducing wind generation is the high generating cost due to low utilization, caused by the greater disturbance in the atmosphere, as compared with Europian nations and U.S. where it is well prevailed.

  • Airdolphin is capable of generating power under conditions ranging from light breeze to gale-force winds.

  • Low Mass: Airdolphin Mark-Zero is only about 17.5kg. This is only 20% of the weight per generated watt of large wind turbines. The light weight also allows the unit to be installed in a wide variety of places, such as placing it on top of your building.

  • Newly designed rotor: Ultra low mass blades, reinforced by a carbon fiber skin of for superior rigidy. This technology allows the turbine to capture wind effectively and respond flexibly to changing condition.

  • Biomimicry: Airdolphin comes with the "silent disrupter blade". This new blade has ability to reduced air flow noise. Designer of Airdolphin were inspired by the wings of owls that fly almost silently and unnoticed while approaching to its prey.

  • Generating power even in hurricane conditions is something that up until now has been considered too dangerous. Airdolphin achieves the seemingly contradictory goals of being both a as well high power as a safer and more durable turbine. (Non-stop power generation between 2.5m/s and 50m/s wind speed)

  • Extensive tests have shown that Airdolphin actually generates more power in variable wind conditions, even when the average wind speed is small. This revolutionary finding suggests that Airdolphin can actually be more cost-effective than large wind turbines.

  • Airdolphin could contribute substantially to the development of the industry by showing the way to new possibilities in worldwide small wind turbine generation. Airdolphin generates 100-120kWh per month for an average wind speed of 6m/s, resulting in an effective annual CO2 reduction of 800Kg / or more.

  • Question and Answers:

    Q. "What is the price?"

    A. "The price is now 500,000 yen, roughly US$4,000. It is still expensive, but as we go into mass production we hope to lower the price soon."

    Q. "What percent of honsehold's electricity need can one Airdolphin provide?"

    A. "In Japan, an average family needs 300 kWh per month. Airdolphin can produce 100 kWh per month with the wind of 5-6m/s, so we can say that 3 Airdolphins would be enough to provide all electricity for one household."

    Q. "What is your future plan?"

    A. "As a unique solution in the field of small-scale wind power production, we will pursue the creation of mini wind farms and micro grids linking independent power supplies for off-grid regions."

  • Food for thoughts: How is wind energy progressing in your region? Do you think that the technology development happening in Japan would be also meaningful in your region?"
