Thirteen Dartmouth College (NH) students and recent graduates are touring the country on an old Greyhound bus converted to run on waste vegetable oil. The Big Green Bus is scheduled to visit 31 states in 11 weeks, spreading the messages of sustainability and environmentalism. “Our focus is two-fold: to discover the environmental success stories of individuals, small businesses and corporations and to share these stories with the communities we visit across the country,” said Laura Coyle, one of the students on the bus. “With every mile, we are building momentum for environmental enthusiasm and innovation.” The bus boasts a series of eco-friendly features, including solar panels, deep cycle batteries and inverter, a bamboo floor, grease filters, and recycled computer cases. You can follow the progress of the Big Green Bus on Twitter; according to the online schedule, the crew should be in Princeton (NJ) today. Link to full story in Wicked Local Marblehead.
