Objective

o Create a solar powered, human-driven, boat that meets and exceeds the requirements of the Solar Splash collegiate competition in June 2017.

o Develop a method of recreational transportation that is pollution-free that can be used in our state, country, and world.

o Showcase solar-electric technology and power transference in a unique manner.

3

What is a Solar Powered Boat? o In a Solar Powered Boat, available sunlight is converted

to electricity by solar cells, temporarily stored in batteries, and used to drive a propeller through an electric motor.

4

Solar Powered Boat using Electrically Chargeable Motor

Advantages* Disadvantages*o Greater energy

efficiencyo Greater power to

weight ratioo Less noise, no

exhaust o Fewer maintenance

requirements

o Limits in battery technology

o Higher Cost

* Compared with an Internal Combustion Motor of similar power outputhttp://www.alternative-energy-news.info/technology/solar-power/

Competition

o Solar Splash is the World Championship of intercollegiate Solar/Electric boating.

o The goal is to design and build a solar, single seat, electric boat and compete in series of events.

o Blends Mechanical, Electrical and Computer Engineering disciplines.

o Date: June 14 – 18, 2017.

o Location: Eastwood Lake, Dayton, OH.

Network and visit Potential Donors to obtain funding for project.

Buy used material and build rather than buy to reduce expenses.

Consult with Industry/Faculty Advisor to obtain optimum design format.

Re-do design, obtain lighter materials and reduce amount of materials..

Adjust design to meet competition requirements

Work with CET students to correct issues
