Project Scope To transport bikers across the Mallets Bay cut we updated the current ferry with two electric motors in conjunction with the current gasoline engine to make use of alternative energy solutions

Our Solution

Original Problem Statement To transport bicyclists across the causeway using the most efficient, environmentally friendly, and cost effective way possible. To transport bicyclists across the causeway using the most efficient, environmentally friendly, and cost effective way possible.

Design Concepts Bridge Bridge Tunnel Tunnel Twin Outboard Biodiesel Twin Outboard Biodiesel Cable Tram Cable Tram Cable Ferry Cable Ferry

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