Japanese solar cars race across Australia on enough power for a hair dryer
Futuristic solar-powered cars have just finished a 3,000-kilometer race across the rugged desert of Australia's Outback in the ultimate endurance competition. Running on enough power for a hair dryer, the fastest reached speeds as high as 130 kilometers per hour and completed the trek in just four-and-a-half days. This was…
The Osaka team said the general approach to designing an energy efficient solar car is that emphasis was placed on improving aerodynamic performance and reducing vehicle weight in order to complete the BWSC. Four leading teams, including Brunel, used an innovation that led to the competition being called “the battle of the fins.” A sharklike fin can be extended up from behind the canopy and turned like a sail to capture crosswinds to propel and stabilize the car. Solar racing has served as a test bed for the batteries, controls systems and lightweight materials now commonly used in production electric vehicles.
