This paper reports about recent our trial of engineering design education through development of a micro wind power generator system and its contest by collaboration between the technical colleges and the university of technology. Micro wind power generator seems to include many points for design, such as fluid dynamics, structure and strength, mechanical processing, material, shape design, electric system, and safety design. Students attended the contest had presentation of their systems and actually conducted power-generation performance test using fan system and electric load. The results showed the promising educational effect for design educations and communications between attendances.
