the world solar challenge in australia brings together wacky racers from across the world - solar powered car air freshener

No harsh tires, no roaring engine, absolutely no bikini
Girls in clothes-Welcome to the Solar World
Racing power.
About 40 cars are 1,864 miles in Australia (3,000km)
Race by the light of the sun. The space-
The age machine participating in the event was designed by a team of students from 23 countries and can be driven at speeds up to 100mph.
I took part in this year's World Solar Challenge on Darwin's starting line, and thousands gathered in state square to wave to the team.
Instead of going around the runway, competitors are traveling along the notorious dangerous Stewart Highway, which takes them south through Alice Springs through the center of Australia and ends in Adelaide four days later.
Along the way, the driver encountered stray cattle and kangaroos, sandstorm is very common, hundreds of miles apart from the town.
No phone reception.
There is no air conditioning in the car to reduce the weight, so dehydration is a serious problem.
However, as Chris Selwood, director of activity, explains, the biggest problem is the huge "road train"-more
Trailer trucks across the interior.
The average body height of solar cars is around 140 kg, he said.
There are 82 wheels on the road train, weighing 140 tons.
This game is not only about speed, but also about endurance, while making sure your driver is mentally prepared.
Cars in the World Solar Challenge, which has been running since 1987, have become more complex and increasingly competitive.
Some teams spend more than £ 1 million on the latest technology.
Selwood says many teams are in touch with technology companies that use competitions to test equipment, as well as automakers such as GM and Ford.
A team has planes.
The other is to use solar cells that are usually found on space satellites.
"One of the biggest sources of spending is the University of Michigan, which arrived with a 15-meter stand truck and a team of military precision training.
A team from Saudi Arabia spent two years building their car, which was destroyed when it was transported by truck to Darwin.
A car at the University of Cambridge in the UK was forced to quit after it was turned over twice during the test.
Driver Alan Jamison said: "The team was frustrated because we spent two years preparing for the game.
Our car is much narrower than most, and we end up with stability issues that could be fixed if we had more time.
"Most cars at elite Challenger level look like tea plates on wheels, carrying only one person.
The rule allows solar panels connected to a bunch of battery packs to measure up to 6 m².
However, the fleet will extend the regulations to the limit, and each vehicle must undergo a rigorous review before it is allowed to participate.
Selwood said it was one of the challenges the team faced in designing the car.
One of the most unusual cars is Stella, a four
Two-seat vehicle with cruiser level entry.
Designed by students in Eindhoven, the Netherlands, it claims to be the world's first solar family car.
Spokesman Charlotte van den huvell said: "Most cars are not actually used in the real world.
Stella has passed the road approval rules in the Netherlands.
Still, no car looks like it was made in a comfortable situation and takes time to reach cruising speed.
The drivers faced an ongoing crosswind battle and sat in their own sweat pool for hours in a row.
Still, Selwood thinks the prestige of winning is worth it.
The team likes to challenge the limits, he said.
There's no reason why we can't all open solar energy-
Power cars one day.
