In the bustling port city of Padang, Indonesia, a innovative solution to harnessing wind energy is taking shape, offering a beacon of hope for sustainable energy solutions in regions with low to medium wind speeds. Rizki Muhamad Amsor, a dedicated researcher from the Department of Mechanical Engineering at Andalas University, Padang, has been leading a groundbreaking study to tap into the power of wind, specifically for the benefit of local fishermen. His work, recently published in ‘Metal: Jurnal Sistem Mekanik dan Termal’ (Metal: Journal of Mechanical and Thermal Systems), delves into the potential of Vertical Axis Wind Turbines (VASV) of the Savonius type, a design well-suited for areas with lower wind speeds.
Amsor’s research focuses on a two-stage Savonius turbine made from lightweight aluminum. Each rotor boasts a diameter of 50 cm and a height of 80 cm, designed to maximize efficiency in the variable wind conditions of Padang. The study meticulously measures key parameters such as wind speed, rotor rotational speed, turbine force, and the electrical output in terms of voltage and current from the generator. The findings are promising: the turbine achieved a maximum wind speed of 5.9 m/s, a peak turbine rotation of 225.8 rpm, and a notable power output of 2 watts, with the highest power coefficient (Cp) at 4.7%. This translates to a capture of 160.2 watts of wind power, a significant achievement for a region with modest wind resources.
“Our goal was to create a sustainable energy solution that could directly benefit the local fishing community,” Amsor explains. “By providing a reliable source of electricity, we can enhance the safety and efficiency of their operations, ultimately improving their livelihoods.”
The implications of this research extend far beyond the shores of Padang. In regions where traditional wind turbines are less effective due to lower wind speeds, the Savonius design offers a viable alternative. This could revolutionize the way we think about wind energy, making it accessible to a broader range of communities and industries. The commercial impact is substantial; as more regions adopt similar technologies, the energy sector could see a shift towards decentralized, renewable power sources.
Amsor’s work is a testament to the potential of innovative engineering solutions in addressing real-world problems. By focusing on a specific community’s needs, the research not only advances the field of wind energy but also paves the way for future developments in sustainable energy technologies. As Amsor puts it, “This is just the beginning. With further refinement and scaling, we can make a significant difference in how we power our world.”
The study, published in ‘Metal: Jurnal Sistem Mekanik dan Termal’ (Metal: Journal of Mechanical and Thermal Systems), underscores the importance of local innovation in driving global change. As we continue to explore renewable energy sources, the lessons learned from Padang could inspire similar initiatives worldwide, shaping a more sustainable and equitable energy future.
