The Evolution: Electric Vehicles and the End of Oil Addiction By Cory Donahue A PROJECT Submitted to Oregon State University University Honors College In Partial Fulfillment of The Requirements for the Degree of Honors Baccalaureate of Science in Mechanical Engineering Presented March 04, 2010 Commencement June 2010 AN ABSTRACT OF THE THESIS OF Cory Donahue for the degree of Honors Baccalaureate of Science in Mechanical Engineering presented on March 04, 2010. Title: The Evolution: Electric Vehicles and the End of Oil Addiction . Abstract Approved by Mentor: ______________________________ Robert Paasch The world is currently using an unsustainable system of meeting its transportation needs with oil. This system is taking a toll on the world environment and on global politics. The physical availability of oil is the system’s most immediate problem and will most likely bring about a transition away from oil dependency. As a solution, the world should replace oil with electricity by replacing cars that use gasoline with cars that use electricity from a battery. Other alternatives, namely ethanol and hydrogen, present a step down from petroleum in terms of sustainability. While electric cars present challenges that can be addressed, their improvements over gas cars justify a very optimistic outlook for the future of transportation. The transition to electric cars has started to occur and will accelerate in the immediate future.

Thank you, Professor Michael Lerner. The advanced car battery class was very relevant to this project. The class paper conveniently made its way into this book. Thank you. Professor Robert Paasch. The space to work independently got me dreaming, and the deadlines got me writing. It was a perfect combination. Thank you, future Dr. David Jensen. You make the perfect “nicer cop” in the “good cop / nicer cop” routine. Thank you, mom, for offering to slap the agent that said I wouldn’t be able to get a book published.
