This handout from the World Solar Challenge shows the Solar Team Twente vehicle "RED Shift" of Netherland in action near Coober Pedy on the fourth day of racing. The World Solar Challenge, an epic 3,000-kilometer (1,860-mile) solar car race across outback Australia, has become one of the world’s foremost innovation challenges with teams looking to demonstrate designs that could one day lead to solar-powered cars for consumers that can carry passengers.
