If you need to spark creativity -- is the best approach to offer a prize? The US government is one backer of such challenge-based research. It recently unveiled Challenge.gov, a director of government-sponsored research contests. Prizes are available for everything from developing better laundry techniques for use in space, to designing more effective public health campaigns. We'll talk about encouraging ingenuity through contests and prizes -- and we'll also hear from the winner of the Progressive Automotive X Prize, a major prize awarded this week for advances in car efficiency.
