Cheering for Kevin Costner

Why do we not have more X prizes? Recently it has been proposed that drug development be funded this way. How about an x prize to the city that diverts the most trash, or the school system that gets the best achievement, or the police force that has the lowest crime rate per dollar?  Kevin Costner’s centrifuge is in the finals running for the latest X prize for oil clean up systems, good luck to the water world star.
