SustainableJeroen writes "On October 6th, the 2013 World Solar Challenge will start. This year, 43 teams (more than ever before) from 24 countries around the world will compete in this biannual 3000 km road event, which runs from Darwin to Adelaide. In both 2009 and 2011, Tokai University (Japan), Nuon Solar Team (the Netherlands) and University of Michigan Solar Car Team (USA) finished in first, second and third position, respectively. Who will win this year? We'll know for sure on October 13th, the end of the event. Team details (photos, car specifications, links to websites) can be found here."
