During my time in Class 7, I had the exciting opportunity to participate in a science exhibition held in Biratnagar. For this event, I developed a unique project that demonstrated how electricity could be generated from a simple cycle. The idea was to harness the mechanical energy of pedaling to produce electrical power.
Using an old mixer motor, I designed a system where the cycle could generate electricity as it was pedaled. The setup involved integrating the motor with the cycle in such a way that the motion of pedaling would drive the motor, which in turn produced electrical energy. This electricity was then used to charge the cycle's battery, making it possible for the cycle to store energy even when pedaled during the night.

The innovative nature of the project lay in its ability to repurpose old equipment—like the mixer motor—into a functional component for energy generation. By demonstrating this concept, I aimed to show how simple mechanical systems could be used to solve practical problems and make efficient use of available resources.

The project was well-received at the exhibition, and I was honored to achieve 3rd place. This recognition was a significant achievement not just for me but for the entire Morang district. The success of this project was a proud moment, showcasing the creativity and problem-solving skills of young students. It reinforced my passion for science and engineering, and motivated me to continue exploring innovative solutions and technologies.
Physics Formula for Converting Mechanical to Electrical Energy
P = V² / R
