This is something helped a bit with getting started when I was in Peace Corps and it is a great contest that works at the grassroots level (which I honestly think is the best way to see success).  So check out this years finalist and vote for yourself!

World Challenge
 

World Challenge 2007, brought to you by BBC World and Newsweek, in association with Shell is all about rewarding individuals or groups that truly make a difference through enterprise and innovation at a grass roots level.

The winner will receive a US$20,000 award from Shell to benefit their project, while two runners-up will each receive $10,000. One representative from each of the three final projects will be flown to The Hague, The Netherlands to attend the award ceremony in December 2007.
