Portable Power Generator: This compact, cupholder-sized generator uses solar strips to power an RC motor, which in turn drives a series of pancake alternators and a cooling fan. The alternators charge and sustain the primary battery, enabling ongoing use. The system supports both USB device charging and AA/AAA battery recharging.
Design Review: Proposed improvements include removing the RC motor, swapping the positions of the primary battery and pancake alternators, and adding a manual high-speed hand crank inset into the bottom cap.
