[00:01.61]How many races have you taken park in?
[00:03.66]Let me think. Six.
[00:06.31]We've won two of them!
[00:08.08]Where do these races take place?
[00:10.19]Well, the one I like best crosses
[00:11.76]the whole of Australia
[00:13.67]from northwest to southeast.
[00:15.83]It's about 4,5000 km¹ long!
[00:18.40]Wow! How long does that take?
[00:21.14]These days the fastest cars
[00:22.54]can do it in six days.
[00:24.26]And what have you been doing recently?
[00:26.81]I've been building a new car with a team
[00:28.96]from Queensland University.
[00:31.00]We've done a lot of work on it,
[00:32.39]but we haven't finished yet.
[00:34.10]And you've been writing a book about solar cars
[00:37.15]Well, so far I've only written
[00:38.80]the first few chapters!
[00:40.65]I want people to have a good impression
[00:43.05]of solar cars.
[00:44.16]But a lot of people think that solar cars
[00:46.34]are too slow or not very reliable².
[00:49.19]How can you persuade them
[00:50.49]of the advantates of solar cars?
[00:53.64]Solar cars are getting better all the time.
[00:56.33]They have reached speeds of nearly 80 k.p.h.
[00:59.78]In tests, one car we built has averaged
[01:02.33]over 40 k.p.h.,even in cloudy weather.
[01:05.81]You've been working hard-well,
[01:08.25]good luck in ther race!  Thanks a lot.
