By building solar sprint cars, a group of high school students learned “green-collar” skills such as converting engine power from solar to fuel cells on the grounds of Western Connecticut State University last summer. Hosted by nonprofit Green Light Academy, the four-week summer residential program for students in grades 10 through 12 used the university’s classrooms and computer lab, conducted experiments in the Science Building, explored the Westside Nature Preserve and enjoyed the playing fields, gymnasiums and recreational facilities. Taught by experienced professors and certified teachers, the students learned through hands-on skill-building exercises.
