MICHAEL HOLAHAN-Paul Knox Middle School students, from left, Benjamin Formby, 12, and Ellie Fuller, 11, put some finishing touches on their future city, called Sea Glass City, during the annual South Carolina Future City competition at USC Aiken Saturday afternoon January 21, 2012. The competition challenges middle school teams to create a future city model based on the theme Fuel Your Future: Imagine New Ways to Meet Our Energy Needs and Maintain a Healthy Planet. The objective was for the teams to design a method of providing electricity for a future city using an energy source that does not deplete natural resources and has limited impact on the environment.
