In conjunction with a national program known as "FreeWays to Fuel" ( freewaystofuel.org), researchers at N.C. State University are working to grow canola and sunflower crops along the wasted edges of highways and other marginal areas.
The national program, which began in Utah and has spread across the United States, originally used municipal zones to plant crops for biofuels. Utah's first harvests are now being used to power Department of Transportation vehicles in Salt Lake County.
