| Summary: | The energy demand kept increasing, in line with the increment of world population. The price of fossil fuel is kept rocketing. Renewable energy is the alternative that had been approached to make sure the sustainability of the energy. The example of sustainable energies is rain, solar, tides, wind, biomass, and hydro. In general, the climate in Malaysia is characterized as high rainfall throughout the year. The collection of rain water can be used to generate an electricity under the concept of rain water harvesting (RWH) system. The purpose of this study is to vary the overlap ratio, ß (0.15 and 0.3) of the Savonius blades in the proposed RWH system. From the analysis, it is shown that for the Double-Stage Savonius blade rotors, higher electricity can be generated when ß is increased. From the finding, it is found that the Double-Stage Savonius blade rotor of 0.15 ß produces power output of 0.12 Watt while 0.3 ß produces 0.13 W, respectively. |
