Retrofit Bicycle-Powered Athena Workstation for Sustainable Laptop Charging

This project explores the retrofit of an exercise bike to create a Bicycle-Powered Athena Workstation, harnessing energy generated by pedaling. A cyclist produces an average of 75 watts at a continuous rate of 63 RPM, which is geared up by a factor of eight to drive a flywheel and generator setup. The generated power charges a 12V battery, which is adapted for use with a laptop via a 12V cigarette lighter adapter. The laptop typically consumes 19.5V at an average of 30 watts, making this a sustainable solution for portable power on-the-go.
