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.
Design Concepts
•
•
•
•
•
Bridge
Tunnel
Twin Outboard Biodiesel
Cable Tram
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.
