The Buckminster Fuller Challenge, a new annual design competition created to honor the late architect-inventor-ecologist who would have celebrated his 113th birthday this Saturday, has a winner.

John Todd, a Cape Cod-based scientist and environmental planner who met Bucky nearly 30 years ago, has taken home the blue ribbon for his “Comprehensive Design for a Carbon Neutral World: The Challenge of Appalachia,” an economic plan that calls for cleaning up and replanting 1.5 million acres of land from Ohio to Alabama that coal producers have strip-mined. The Buckminster Fuller Institute, a Brooklyn-based research group, sponsored the contest and announced the winner on May 1.
