SOLAR CAR.

This strange car doesn't use petrol.. it uses the sun!
The car took part in the World solar Challenge 2009, Australia.
32 solar cars from 17 countries drove from the north to the south
of Australia - a distance of 3,021 KM- using only the sun's
energy. The challenge was to show that solar cars really work.
So perhaps one day, we will all have solar cars!
