Final GoalFinal Goal

• Upon completion of the project our team will Upon completion of the project our team will have designed, tested, and built an have designed, tested, and built an alternative energy system consisting of a alternative energy system consisting of a windmill, a battery bank, and two electric windmill, a battery bank, and two electric motors operating in parallel with the existing motors operating in parallel with the existing gasoline outboard. The system will be easily gasoline outboard. The system will be easily upgradeable, allowing for the integration of upgradeable, allowing for the integration of more alternative energy sources as funds or more alternative energy sources as funds or future development permit.future development permit.
