[00:08.80]Solar Car Racing

[00:11.84]Solar racers have been coming to Australia

[00:14.08]for years for the World Solar Car Challenge.

[00:17.38]We interviewed Marie Logan from Brisbane.

[00:20.65]Well, the first question I have for you

[00:22.85]is simple. What is a solar car?

[00:26.25]Solar cars are cars that use the sun's energy

[00:29.19]for power.That means they don't use petrol,

[00:31.40]gas or any other fuel,just the sunlight.

[00:34.80]And why are people interested in solar cars?

[00:38.17]Well, people have been worried about pollution

[00:40.61]caused by fuels like petrol andgas

[00:42.99]for a long time now.

[00:44.79]Solar cars are clean and safe

[00:46.47]so there is a lot of interest in them.

[00:48.37]You've been designing solar racing cars

[00:50.73]for a long time.

[00:52.34]When did you start?

[00:53.88]Well, I've been interested in cars

[00:55.82]since kindergarten.

[00:57.56]When I was at university,

[00:58.86]I started designing my car.

[01:01.05]I've designed five or six different cars so far

[01:04.00]And I've been taking part in races

[01:06.10]for about four years.
