“Although solar power has been used in less spectacular ways, this was the first trans-continental crossing in a vehicle deriving its energy from the sun.”

August 24, 2016—-“Maybe one day we’ll all be driving around in solar-powered cars. And, if that happens, the names of Hans Tholstrup and Larry Perkins will have a place in history. Without men like these, this would be a duller place. The spirit of adventure is not yet dead.”—Melbourne Herald News
The Quiet Achiever
In Australia in 1982, Perth and Tholstrup, wanting to popularize solar, built the first solar-manned car to cross a continent. With an attitude of, “There’s nothing that can’t be done,” they built the solar vehicle for about $50,000. The car, known as the Quiet Achiever, was designed in only 8 months. It was piloted by Perkins and Tholstrup who only stopped along the route at night to camp. In less than 20 days, the solar powered car made its trek from Perth to Sydney, traveling 2,500 miles from coast to coast across Australia.
Using Only the Sun’s Power
The body of the solar car was made of fiberglass and the frame of steel tubing. It had a 1 kilowatt photovoltaic power system mounted on the roof that allowed it to travel approximately 14 miles per hour. Using only the sun for power, the two 12 volt batteries stored enough power to give the car about 90 minutes of energy without the sun. But on this trip there was enough sun to keep the car fully charged at all times. The solar car met with very few problems and was periodically monitored to assure that only solar power was being used.
The Melbourne Age newspaper stated at the time, “The journey of Hans Tholstrup and Larry Perkins from Perth to Sydney in The Quiet Achiever will go down as one of the pioneering feats in history. Although solar power has been used in less spectacular ways, this was the first trans-continental crossing in a vehicle deriving its energy from the sun. It constitutes the fastest chapter in man’s learning how to co-operate with powers beyond his own–the sun!”
