It is difficult for developing countries to introduce renewable energies such as wind and solar as actively as developed countries to reduce the carbon dioxide exhaust. Therefore, it is necessary to design wind turbine based on the appropriate technology concept for the developing country. The appropriate technology means; 1. low-cost, 2. simple design, 3. easy to construct using local materials, 4. possible to maintain and repair by local people. The authors experimented systematically in the wind tunnel using the model wind turbine with the bended-plate type Hades which could be easily introduced to developing countries based on the design concept of appropriate technology.
