Dutch car wins solar power race. Is technology that far behind?

A Dutch car overtakes a competitor going 81 miles per hour through the blazing Australian outback, then at 56 m.p.h., finishing the 1,800 mile race first 鈥� all without using a gallon of gas.
The solar car race in Australia on Thursday, which a vehicle from Delft University won for the second consecutive time, displays the upper limits of solar power, and researchers are challenged to develop a working car that could lead to a consumer model.
The main rule of the World Solar Challenge, a race for about 50 cars occurring every two years since 1987, is that for power, the BBC reported. Cars may store only 5 kilowatts of energy 鈥� by contrast, a single light bulb on for 10 hours a day uses , according to Forbes. Each car must take the rest of its power from the sun or from the motion of the car itself.
The Australian outback provides plenty of sun, although even that .
"(Distilled water) is used to spray over solar arrays at control stops to keep the temperature down (and consequently: to maximize the output)," Michael Van Baal, the winning team's spokesman, wrote on the Nuon Solar Team blog. "Finding demi-water in October is pretty hopeless, as all top teams need it, so you better stock up early."
The distilled water is better than tap water, which leaves a layer of salt on the solar panels as it evaporates.
"The past decade has been a remarkable time for the solar industry. Last year up to a third of all new generation capacity in the US was solar," Francis O鈥橲ullivan, director of research and analysis at MIT鈥檚 Energy Initiative, told 海角大神. "However, continued rapid growth in solar is not an inevitability."
Solar power technology, such as Tesla's idea of has potential. But it is not ready for use, Bloomberg reported.
"Despite the Tesla announcement, we鈥檙e not there yet," said Richard Schmalensee, chairman of an MIT Future of Solar Energy study, according to 海角大神. "We鈥檙e not close to being there yet."
Working with solar power continues to require a full measure of flexibility. The World Solar Challenge started Sunday in Darwin, Australia, and ended Thursday in Adelaide, the BBC reported.
Temperatures reached 111 degrees Fahrenheit, and the racers did not want to use an ounce of their sun-produced energy on air-conditioning. The drivers exercised and trained in heat rooms beforehand to prepare. But during the race itself, their best ally was water, UPI News reported. The Delft University team even put a hole in the car itself to the drivers generated under the blazing sun.
