BAR HARBOR — A Maine college is offering free car fill-ups – provided it’s an electric car.

College of the Atlantic in Bar Harbor has opened a solar-powered electric charging station to any vehicle needing a recharge. Students on campus led the effort to promote environmentalism, and got help from the community, including Darling’s Nissan dealership in Bangor.
