MARBLE FALLS — Drivers along U.S. 281 in Burnet County might have noticed something odd July 21.
They weren’t spaceships — or boats on wheels.
Instead, the unique vehicles were solar-powered cars participating in the American Solar Challenge.
The race covers seven states in eight days and includes 23 teams from universities in the United States, Canada, Puerto Rico and Iran. The teams started July 21 in Austin and will finish in Minneapolis on July 28.
Each car is capable of reaching speeds well above any speed limit; however, rules limit the top speed during the race to 65 mph. Team members ride in vehicles that lead and follow the solar car during the race.
Teams race from 9 a.m. to 6 p.m. each day to their next checkpoint. The quickest elapsed time for the stages determines the winner.
