The grueling, 630-mile road race where the only fuel is sunlight

On July 19th, dozens of teams of high school students will begin a five-day, 630-mile road race from Fort Worth to Fort Stockton in Texas. But this is not your typical contest. The students design and build the cars themselves, using off-the-shelf parts and 3D printed materials. The winner is the team that accumulates the most driven miles. And the only fuel they can use to power their Frankenstein-looking vehicles comes from that mass of incandescent gas that hangs in our sky: the Sun.
