Studio 360 saves the planet. On the 40th anniversary of Earth Day, we explore design solutions for a changing environment. Kurt Andersen visits a solar-powered subway station in Coney Island and talks to an engineer making biofuel from bacteria. And meet the creative thinkers behind a hand-cranked street generator, the adobe house of the future, carbon-neutral rock shows, and the Eco Art movement.

Special thanks this week to producer Sarah Lilley. Funding for our series on Creativity and Science is provided by the Sloan Foundation.
