Integrating sustainability and economic efficiency in renewable power: A Dual-Source Pico Hydro–Steam Turbine Design

The purpose of this research is to design and fabricate a Pico Hydro-Steam Turbine that combines steam and rain-catching technologies for power generation, addressing identified issues and implementing modifications to enhance efficiency. The research used an experimental-developmental approach, involving the concept development, testing, and prototyping phases. It was revealed that in the water phase, the turbine requires a flow rate above 0.0000574 m³/s to produce electricity, and in the steam phase, it begins to spin when the pressure exceeds 42.8 PSI. Measured efficiencies reached 94.164% in the water phase and 81.549% in the steam phase at the highest water flow rate and pressure, indicating that the turbine could operate at even higher efficiency. It was also observed that the increased flow rate and pressure enhance turbine performance. Statistical analysis of Trial 1 showed significant differences in the independent variables water flow rate and pressure flow with values of 0.011 and 0.023, respectively, both below the 0.05 significance level. This confirms that these independent variables have an impact on the turbine's performance. The findings are informative for energy companies, utility providers, homeowners, and future researchers, offering insights into optimal operational thresholds. The study recommends the use of rainwater in the water phase, steam powered by solar energy in the steam phase, incorporating control elements, and adding battery storage. This research confirms that integrating water and steam technologies within the Pico Hydro-Steam Turbine for electricity generation is efficient and has the potential for further improvement.
