The World Solar Challenge: Designing cars for our future/

“The World Solar Challenge contest is primarily designed to find the world’s most efficient solar car and to inspire some of the brightest young people on the planet to address the imperatives of sustainable transport!”

September 12, 2016—-The World Solar Challenge (worldsolarchallenge.org) is a solar car race that takes place in Australia every two years. Teams from universities, corporations and even high schools from around the world participate to promote research on solar-powered cars. The solar car race began in 1987 and in 2015 there were 43 teams from 23 different countries entering the race. The 30th anniversary of the race will be October 8-15, 2017.

The Solar Car of the Future

Hans Tholstrup and the Solar Car

The idea for the contest came from Hans Tholstrup who was the first to navigate a solar car coast to coast across a country–Australia. In 1982 Hans Tholstrup, along with Larry Perkins, drove their solar car across Australia in 20 days. (See article, “The First solar Car to Cross a Continent”, Planet Earth Weekly, August 24, 2016.) The contestants in the World Solar Race are allowed 5kw hours of stored energy, which is about 10% of the necessary energy to make the trip across Australia, a total of 1900 miles. All other energy must come from the sun, or the kinetic energy generated from the motion of the vehicle.

The Solar Achiever

The solar car traveled 2500 miles in 20 days.

The Solar Car Race

Every two years the race starts in Darwin, Northern Territory in Australia and ends in Adelaide, South Australia. According to worldsolarchallenge.org, “Once the teams have left Darwin they must travel as far as they can until 5pm in the afternoon, where they make camp in the desert wherever they happen to be. All teams must be fully self-sufficient and for all concerned it is a great adventure – many say the adventure of a lifetime!” During the journey there are 7 mandatory check points where team managers may update themselves with the latest information on the weather and their own position in the field and perform the most basic of maintenance only, checking and maintenance of tire pressure and cleaning of debris from the vehicle.

The Solar Car Categories

There are 3 categories of solar cars. The Challenger class makes the trip in a single stage from Darwin to Adelaide. The Cruiser Class is conducted as a regularity trial and the Adventure Class is a non-competitive class which consists of cars built for previous events.

My goal, as a responsible adult, is to leave a planet that people, plants, and animals can continue to occupy comfortably. I am an educator by profession. While educating myself on Climate Change and Renewable Resources, I hope to share my knowledge and images with those that share my concern. Dr. John J. Hidore is a retired professor from the University of North Carolina at Greensboro and I am proud to call him my Uncle. His work has taken him to regions across the globe—including the Middle East, where he conducted research for a year in the Sudan. He has written many books, such as Climatology: An Atmospheric Science and Global Environmental Change.----Linn Smith
