ChargeCycle: Charging AA Batteries with Pedal Power

Our group's project is from the freshmen IntroSem, The Art and Science of Engineering Design, taught by Professor Andrea Goldsmith and Dr. My Le. Our goal is to provide clean, green energy to communities without electricity or a consistent source of light. Today, over 1.2 billion people (20% of the world's population) are still without access to electricity worldwide, almost all of who live in developing countries.  ChargeCycle will attempt to provide for this need using bicycles and pedal power. Although products currently exist and provide electricity by harnessing the rotational motion of the wheel, our group has recognized some flaws in these designs and has attempted to provide a product that provides a more efficient and effective method. Our product will harness the energy generated by a bicycle rider to charge AA batteries or power a USB port. The design will be elegant, compact and effective, providing the user a method for charging AA batteries or any other device using a USB port.
