Substantial prizes like the ten million dollars X Prize have been br spurring progress since the 1920s when Charles Lindbergh stepped up to br the twenty-five thousand dollar purse he went on to claim. Virtually br any innovation that will benefit humanity is up for an X Prize - from br sequencing the human genome, to skimming surface oil, to mobile br medical diagnosis (sponsored by Qualcomm) to early detection of br tuberculosis (sponsored by Bill and Melinda Gates). These purses are br incentivizing teams to solve problems for the greater good and each br effort will produce ten times the amount of the prize itself in br spending for research and development.
