American Zephyr - Empowering the Wind to Energize the World

Zephyr's dream is to transform ever-changing winds into clean electric energy, and to make this power available at any location in the world. So we launched Project Z — the most ambitious small wind turbine technology project in Japanese history — combining research and know-how of leading experts in government, academia, and industry.

Project Z spent six years in developing the Airdolphin — a next-generation, lightweight wind turbine that can instantly adapt to changing wind conditions.

Through extensive testing in windy sites around the world, Airdolphin has proven tough, efficient, and reliable. It instantly responds to the vagaries of wind, while delivering over 170 kWh per month at average wind speeds of 6 m/s (13.4 mph).
