In Japan, "Natural energy" is expected to play a part in improvement of the self-sufficiency of energy supply. Micro hydropower has great potential water power. Micro hydropower is mostly in "run-of-river", without dam or water storage. It is one of the most environmentally benign technologies and is useful for local independent power supply. However, the cost performance is the principal obstacle to familiarize micro hydropower widely. In this study, for price-reduction of micro hydropower, I made stator vane which was made of PVC board and pipe and a propeller of outboard motors was applied to a turbine blade. The turbine blade was improved to achieve high efficiency and increased output, the micro hydropower performance was examined by experimental study. As a result, the best performance was obtained as the output of 1.503kW.
