Daiwa House Industry Central Laboratory

Compact Wind Power Generator

We contribute to the prevention of global warming through our development of the wind powered generator that creates electricity from wind.

Background and Purpose of Development

• 1. Prevention of global warming
• Wind power generation, which transforms the wind's energy into electrical energy, contributes to preventing global warming, as it does not emit CO2 while generating power.
• 2. Utilization of unused energy
• The clean and inexhaustible energy, wind, found anywhere on earth, is effectively utilized.

Contents of Development and Results

Joint Development Organization

Daiwa House Industry: Wind turbine design technology / Control technology / Technical guidance

Joint development partners: Development of component equipment / mass production design / production

Kazenagasukujira, which literally translates into "the whale that lets the wind flow": 10kW Wind Power Generator
Joint Development partner: Nikko Company (production of china, residential environment equipment, and ceramics)

Sales collaborator: Nikko Company, Daiwa Energy Co., Ltd.

It can generate power efficiently even at low wind speed, since the wind turbine rotates at a wind speed of 2.5m/s, and captures the wind direction accurately with its wind vane.

Eco Gyro
Joint development partner: Inaba Electric Work Co., Ltd. (produces lighting fixtures and power controllers)

Sales collaborators: Inaba Electric Work Co., Ltd., and Daiwa Energy Co., Ltd.

By combining the Gyro Mill (dynamic lift type) and paddle wind turbine (drag type.) it effectively uses the wind and solar rays, and rotates by accurately capturing the wind from various directions, By combining the wind turbine and solar generator panel, it can generate energy stably.

The photograph is of Eco Gyro, which operates on a dynamic lift type and drag type hybrid system.

Hybrid Chimney
Joint development partner: Inaba Electric Work Co., Ltd. (production of lighting fixtures and electric controllers)

Sales collaborators: Inaba Electric Work Co., Ltd. and Daiwa Energy Co., Ltd.

The world's first domestic wind powered generator developed for integrating homes with wind turbines.
Attention has been paid to aesthetics by combining the drag type Savonius wind turbine and solar energy generator. The generated energy is used mainly for the 24-hr ventilation system and outdoor lights.
