Solar powered car racers set off in Australian challenge
BARROW CREEK, Australia - More than 40 racing teams from two dozen countries left Darwin on Sunday to race across Australia to the southern city of Adelaide in the 2015 Bridgestone World Solar Challenge.
The 3,000 kilometer (1,864 mile) trek is one of the most prestigious solar car races. The biannual event first began in 1987 and is based on the original notion that a 1000 watt car would complete the trip from Darwin to Adelaide in 50 hours.
