Airdolphin PRO / Mark-Zero
traditional Japanese handicraft techniques.
●The core rotor has three ultra-light carbon fibre blades, embossed to
dramatically reduce air flow noise.
●Programmed to automatically rotate 10 seconds per minute in low wind
conditions, to kick-start rotation.
●The robust body and power generation unit can produce power at up to 50m/s
wind speed, which is more than double speed of other existing systems.

Zephyr always believed that unless wind turbines perform far above current standards, they will never become an alternate universal power generator. Based on this concept, we created a new development scenario for a small wind turbine targeted for the global market, and asked experts for their opinions. While examining the various possibilities, we met Hikaru Matsumiya (then member of the National Institute of Advanced Industrial Science and Technology, currently a professor at Kyushu University), which eventually led to the start up of this project. The joint development venture between industry, academia, and government has united people, knowledge, and technologies at the highest level.
Experts from every field related to wind turbine development, such as hydrodynamics, electronics, materials, processing technology, and others, have gathered for this project organized by Zephyr. In developing a new model, we aimed for a product with high customer satisfaction, based on a consistent marketing philosophy -- from design, research, development, to manufacturing and sales. The numerous failures with other manufacturers' turbines we have experienced over the past eight years contributed valuable data for our research enabling us to come up with solutions for what has long been perceived by engineers as conflicting design goals. We have been able to succeed with the development of a superior wind turbine that is both safe, quiet, and inexpensive while achieving a high power generation efficiency.
