The challenge attracted thousands of bright, innovative visions, which the judges have now narrowed down to the best of the best. Four of them will win $25,000 each, and one of those, the People's Choice, will be determined by audience votes.

People from all over the world have shared their ideas at CHASING GENIUS since the contest opened in June—students and teachers, researchers and retirees, science geeks and free thinkers. Among the finalists, there are solutions for cleaner water, smarter food production, and preventing diseases. In scope, the concepts range from connecting whole communities to reinventing items small enough to put in our pockets. But one thing they all have in common is notion that one seemingly simple idea can have huge impacts.

Spouts of Hope While spending a summer in Uganda teaching school, Kathy Ku experienced first-hand one of the biggest problems facing Ugandan families today - access to clean drinking water. Teaming up with a fellow Harvard student, she devised a solution.

As submissions flowed in, they sparked lively discussions, drawing questions about how the proposals work and generating new thoughts about how they could be made even better. Some commenters pointed to others' ideas (or their own) that might be of interest. It was clear that all of us have something to contribute when it comes to making the planet more sustainable, improving global health, and feeding 9 billion people.

Now it's time to select a winner, and your opinion counts. To vote, visit the finalists page on CHASING GENIUS and pick your favorite. Voters can each weigh in once a day until September 15.
