A Renaissance man if ever there was one, Saul Griffith is a recipient of a MacArthur Foundation grant, and a renowned inventor, entrepreneur, and environmental activist. He has founded several start-ups that explore outside-the-box solutions to environmental problems. Onya Cycles, one of his current ventures, offers a healthy and low-impact solution for short-range commuting and urban transportation. Saul's unique approaches to problem-solving, and his many impressive inventions, have made him extremely influential in the green and maker communities. In early fall 2010, he was a guest on The Colbert Report.
