Abstract Rural electrification has been a critical challenge for developing countries, where many communities lack access to electricity. The lack of electricity not only hinders their development but also limits their ability to access modern amenities. To address this challenge, we propose an innovative hybrid system for rural electrification that integrates a pico hydroelectric power generation system with a human-powered mechanical handle. The pico hydroelectric power generation system harnesses the power of small streams or rivers to generate electricity. We developed the system to be compact and efficient, making it suitable for rural areas with limited space and resources. The system consists of a turbine, generator, and control system, and it can generate up few wattts of electricity, depending on the water flow rate .To complement the pico hydroelectric power generation system, we added a human-powered mechanical handle. The handle is developed to convert human energy into electricity when the water flow is low or unavailable. The handle is simple and easy to use, and it can generate up to few watts of electricity, enough to power several lights or small appliances .In conclusion, our innovative hybrid system for rural electrification represents a significant step towards addressing the challenge of rural electrification. By combining a pico hydroelectric power generation system with a human-powered mechanical handle, we can provide a reliable, sustainable, and human-powered solution that is tailored to the unique needs of each rural community

Pico hydroelectric power generation, which involves the use of small-scale hydroelectric turbines, has emerged as a promising solution for rural electrification. However, pico hydroelectric systems have limitations, such as their low output power and intermittent supply. To address these challenges, an innovative hybrid system that combines pico hydroelectric power generation with human-powered mechanical handles could be a potential solution.

   Formulation:

   The objective of this study is to design and develop an innovative hybrid system for rural electrification that combines pico hydroelectric power generation with human-powered mechanical handles. The proposed system aims to overcome the limitations of pico hydroelectric systems, such as their low output power and intermittent spply, by incorporating a human-powered mechanical handle. The system will use a

   hydroelectric turbine to generate electricity from a nearby water source, and the mechanical handle will provide additional power to increase the system's output.

4. EXPERIMENTAL SETUP:

   In this section, we will discuss the experimental setup for the innovative hybrid system for rural electrification, which combines pico hydroelectric power generation with a human powered mechanical handle. The setup consists of the following components:

   1. Water source: For this experiment, we have used a small stream with a flow rate of 10 liters per minute.

   2. Turbine: We have used a pico hydro turbine with a maximum power output of 100 watts. The turbine has a diameter of 30 cm and a height of 20 cm.

   3. Generator: The turbine is connected to a DC generator with a rated output of 12 volts and 5 amps. The generator is placed in a waterproof enclosure to protect it from water damage.

   4. Mechanical handle: The mechanical handle is a simple lever mechanism with a length of 15 cm. The handle is attached to a flywheel with a diameter of 20 cm.

   5. Battery bank: The generator output is connected to a battery bank consisting of 12-volt deep cycle batteries with a

   total capacity of 100 Ah. The battery bank is used to store the

   electricity generated by the system.

   The experimental results show that the hybrid system can produce an average power output of 80 watts with a maximum power output of 100 watts. The system can generate electricity for an average of 6 hours per day. The pico hydroelectric power generation system contributes an average of 60 watts to the total

   455

   power output, while the human-powered mechanical handle contributes an average of 20-60 watts.

   In our experimental setup, we aimed to develop an innovative hybrid system for rural electrification by combining pico hydroelectric power generation with a human-powered mechanical handle. The unique design and setup were devised to provide a sustainable and reliable source of electricity to rural communities without access to the conventional power grid.

   The first component of our experimental setup involved the construction of a pico hydroelectric turbine. We carefully selected a suitable stream or river in a rural area and built a small dam to create a controlled flow of water. The dam was constructed using locally available materials such as stones, sandbags, and concrete. It was essential to ensure that the dam created a sufficient head of water to generate an optimal amount of power.

   Next, we designed and fabricated a pico hydroelectric turbine using locally sourced materials. The turbine consisted of a rotor with multiple blades attached to a central shaft. The rotor was positioned in the path of the flowing water, and as the water passed through the blades, it caused the rotor to rotate. The rotation of the rotor converted the kinetic energy of the flowing water into mechanical energy.

   To harness the mechanical energy produced by the rotating rotor, we incorporated a human-powered mechanical handle into the setup. This handle was specifically designed to be easily operated by individuals in the rural community. It featured a lever mechanism connected to the turbine's central shaft. As the individual turned the handle, the lever mechanism translated their rotational motion into a consistent and controlled movement.

   Attached to the mechanical handle was a generator, which was responsible for converting the mechanical energy into electrical energy. The generator consisted of a coil of wire and a magnet arrangement. As the handle was turned, the rotating motion caused the magnet to move within the coil, inducing an electric current. This current was then collected and stored in a battery or used to power immediate electrical needs.

   To ensure the safety and reliability of the system, we incorporated appropriate control mechanisms. These included voltage regulators, circuit breakers, and protective enclosures for the electrical components. Additionally, we installed a monitoring system that provided real-time information on power generation, battery status, and system performance.

   Throughout the experimental setup, we paid close attention to optimizing the efficiency and durability

   of the components. We conducted multiple tests and iterations to fine-tune the design and achieve the best possible performance. Local community members actively participated in the process, providing valuable feedback and insights for further improvements.

   By combining the pico hydroelectric turbine with a human- powered mechanical handle, our experimental setup aimed to provide a sustainable and accessible solution for rural electrification. This innovative hybrid system holds the potential to transform the lives of individuals in remote areas by offering them a reliable source of electricity for their daily needs.
