Two Germans, Stefan Simmerer and TV host Dirk Gion, managed to break three world records in a wind-powered car in Australia recently, taking the 'Wind Explorer' on an epic 18-day journey across the country covering over 4800km, powered by wind alone.

The car, called the Wind Explorer, uses an electric motor that is powered only by wind. At night time in between driving stints, the pair set up a large wind turbine that generates power all night. Then, during the day, if power is running low or if there's plenty of wind around, the co-driver whips out his kite to assist vehicle motivation.

In the process of the completely emission-free drive, the pair set three new world records: the first to cross the county in a wind-powered car, the record for travelling the longest distance in a wind-powered car in a 36-hour period, and the record for covering the most distance overall in a wind-powered car.

Take a look at the videos below for a bit of an insight as to how the wind turbine and kite system works.
