1 APEGGA Presentation Nov. 3, 2005 Solar Cars – Whats The Point? Presented By: Colby Bell Project/Mechanical Manager

2 APEGGA Presentation Nov. 3, 2005 Our Reason for Being: ExperienceEducateExcite

3 APEGGA Presentation Nov. 3, 2005 Experience Compete and represent the University of Calgary at world renowned solar vehicle races Collaboration between multiple disciplines and the community in order to achieve a monumental goal - build a solar car!

4 APEGGA Presentation Nov. 3, 2005 Educate Take advantage of the opportunity to learn skills beyond the scope of the classroom Teach the concept of renewable energy to students in a practical way

5 APEGGA Presentation Nov. 3, 2005 Excite! Showcase Calgary technology and innovation, increasing attention to energy and lifestyle alternatives Succeed at proving, once again, that Calgary is a great host for a major event

6 APEGGA Presentation Nov. 3, 2005 North American Solar Car Challenge July 2005 / 2007 Austin to Calgary ~4000km First Rookie team to ever finish the race 13 th Place overall Learned how to run a race The Rayces

7 APEGGA Presentation Nov. 3, 2005 Darwin to Adelaide No Speed Limit Through The Outback A chance for Western Canada to be recognized for our educational excellence World Solar Challenge September 2005 / 2007 The Rayces

8 APEGGA Presentation Nov. 3, 2005 World Champions Production Class 10 th place overall Learned how to win World Solar Challenge September 2005 / 2007 The Rayces

9 APEGGA Presentation Nov. 3, 2005 How Did We Achieve Our Goals? 1) Formed a team of incredible people 2) Designed and built a winning car 3) Formulated an effective racing strategy 4) Forged partnerships with community champions 5) Shared our experience through educational endeavours and other events

10 APEGGA Presentation Nov. 3, 2005 The Team Over 100 students:

11 APEGGA Presentation Nov. 3, 2005 Solar powered vehicles Utilize solar power as a source of power for moving the vehicle (generally photovoltaic cells) Utilize solar power as a source of power for moving the vehicle (generally photovoltaic cells) Must be designed to be extremely energy efficient due to limited power availability Must be designed to be extremely energy efficient due to limited power availability Onboard energy storage used as a buffer Onboard energy storage used as a buffer –e.g. flywheels, batteries, etc.

12 APEGGA Presentation Nov. 3, 2005 Solar Car Design Rules Car must be no larger than 1.8m wide, 5m long, and 1.6m high Car must be no larger than 1.8m wide, 5m long, and 1.6m high Solar cells determine Class Solar cells determine Class Battery weight is limited depending on battery technology Battery weight is limited depending on battery technology
