Sydney
(AFP) - An epic 3,000-kilometre (1,860-mile) solar car race across the desert
heart of Australia designed to showcase new technology that could one day help
develop commercial vehicles got underway Sunday.
The World
Solar Challenge, first run in 1987 and last held in 2015, began in a high-tech,
futuristic flurry from Darwin's State Square.
Dutch team
Nuon is aiming to defend its title but Belgium's Punch Powertrain led the 41
cars -- powered by the sun and mostly developed by universities or corporations
-- off on the punishing journey south to Adelaide after a surprise win in
Saturday's time trial.
"We
knew our car was good but we never expected pole because there are a lot of
competitors over here, a lot of very fast looking cars," team manager
Joachin Verheyen told reporters.
The event
has become one of the world’s foremost innovation challenges with teams looking
to demonstrate designs that could one day lead to commercially available
solar-powered vehicles for passengers.
Google
co-founder Larry Page and Tesla co-founder J B Straubel are past competitors
who credit the event in influencing their careers.
The main
action will be the streamlined Challenger class -- slick, single seat
aerodynamic vehicles built for sustained endurance and total energy efficiency.
Dutch team
Nuon crossed the finish line first two years ago, taking 33.03 hours to make
the punishing trip ahead of Japan's Tokai University, the 2011 winner, in a
nail-biting climax.
Both teams
are again in the hunt this year, with cars from the United States, Australia,
Malaysia, India and South Africa among competitors up against them.
There is
also a Cruiser class which aims to showcase solar technology for mainstream
vehicles that are more practical for day-to-day use.
Entrants
come from Hong Kong, Singapore and even Iran.
"Of
course, the point of this challenge is not just to go fast, or to develop
technology that will never reach the mainstream," said event director
Chris Selwood.
"Our
founder, Hans Tholstrup, and competitors past and present, are all determined
to make sustainable, energy positive, solar electric cars and renewable
technology a reality."
Teams are
allowed to store a small amount of energy but the majority of their power has
to come from the sun and their vehicle's kinetic forces.
Crews are
allowed to drive between 8am and 5pm each day and simply set up camp wherever
their car pulls off the road at the end of the day. The first car to cross the
line in Adelaide is the winner.
There are
seven checkpoints along the route where drivers can get updates on their
standings, the weather, and do basic maintenance -- clearing any debris from
the car and adjusting tyre pressure.
