Micro Hydro Generator Turbine

This study developed a micro-hydro generator turbine utilizing water flowing into a single inflow pipe which makes the turbine rotate continuously within a specific water pressure. The device is intended to be connected to the household's main water pipeline to generate energy and convert it into electricity that can operate small devices during emergency power outages. It comprises a turbine, generator, step-down voltage, charger module, rechargeable battery, and dc-dc boost module. From the tests conducted, the device generated an average voltage, current, and power of 4.99 V, 0.48 A, 2.40 W at 35 psi, and 4.36 V, 0.35 A, 1.54 W at 20 psi. The power efficiencies of the device at 35 psi and 20 psi were 23.97% and 15.44%, respectively. The percent charge of the built-in battery increases by 1% after an average of 9 minutes and 14.6 minutes for high and low pressure, respectively. The results showed that the device generated enough energy to supply small devices rated 5 volts like smartphones, power banks, portable lamps, and portable fans.
