We designed and built a human-powered demonstration system to teach students and the public about electricity generation through interactive outreach events. The project aimed to combine physical activity with hands-on learning by allowing participants to ride a stationary bike to generate electricity that directly powers a slot car on a modified track.
We tested multiple components to ensure compatibility, reliability, and safety throughout the design process. The final system integrates a bike-mounted generator, power control electronics, and a modified slot-car track that operated entirely on rider-generated power. We added an LCD display to provide real-time feedback on power output and system status, helping users visualize the relationship between their pedaling effort and electrical energy production.
The system performed successfully during outreach events, where participants observed immediate cause-and-effect relationships between pedaling speed and car velocity. This direct feedback effectively illustrated fundamental concepts including energy conversion, electricity generation, and mechanical-to-electrical power transfer. We prioritized accessible materials and intuitive operation to minimize intimidation factors for diverse audiences.
The project achieved its educational objectives by delivering an engaging, experiential learning platform that demonstrated practical engineering principles. User responses indicate increased interest in engineering and technology following interaction with the system. The demonstration proved effective across age groups, showing that engineering education can be made accessible and exciting through tangible, interactive experiences that connect physical effort to measurable electrical outcomes.
