Career and technical education is already ahead of the curve, since automotive technology, electrical technology and electronics students across the nation have been actively engaged in learning about hybrid, electric and even solar-powered cars. Students in the Environmental Technologies Club at Central High School in Phoenix, Arizona, have built a solar hydrogen vehicle and are now working on a vehicle they plan to enter into the American Hydrogen Association's Alternative Fuel Go-Cart Race. This article discusses the students' learning experiences in the Eau Claire North High School Electronics 3 program. These students and in the other career and technical education programs that are building alternative-fuel cars, are doing more than simply building a toy and racing it; they are learning technical skills, modeling teamwork, building problem-solving capabilities and exploring innovative technologies. Through hybrid car programs, career and technical education is designing and building a more efficient future. (Contains 6 photographs.)
