Fuel economy is hardly the most popular subject among teenagers, but itâ€™s a passion for 17-year-old Jonny Cohen, whoâ€™s found a way to save schools money and reduce greenhouse gas emissions by increasing school bus fuel efficiency.
The idea popped into his head on a walk home from school when he was 12. The then-seventh-grader was taking summer classes on aerodynamics at Northwestern University, and it dawned on him there must be a way to streamline the bulky, boxy shape of school buses.
â€œI like to see things that are efficient. Things that are inefficient use more energy and are polluting,â€ said Jonny, who lives in Highland Park, Illinois. â€œI also understood that reducing carbon emissions from a school bus could reduce global warming.â€
With the help of friends and his sister Azza Cohen, a more formal effort took shape in 2008. They called it the Greenshields Project.
