The 30th annual World Solar Challenge is currently underway in Australia.

High school and university students from all over the world including America, Japan, Germany and Switzerland have built solar-powered cars to race each other across the country’s remote outback.

The 3,000km route from Darwin in the Nothern Territory to Adelaide in South Australia takes participants around four to five days, at just over the halfway mark, Nuna9, the car from the Dutch Nuon Solar Team, at the head of the pack.

Here’s a map of the route from the top to the bottom of the country, which would take a car 33 hours to drive.

Poor weather conditions (ie cloud cover) this year have reduced the energy produced by the solar panels powering the cars, so all teams are facing a tough slog.

Here are some photos of the race as it tracks through the Australian outback.
