This is no ordinary challenge, and this is no ordinary car.

From 21 to 28 October, 2007, follow Team Ethanol as we journey 3,500 km (2,200 miles) from Darwin to Adelaide through the Australian outback in the Panasonic World Solar Challenge .

This is the 20^th anniversary of the event in Australia and it will be huge, with entrants and news teams flying in from all over the world.

We are in the Greenfleet division driving a Saab BioPower car that runs on 85% ethanol made from sugarcane.

Traveling through one of the harshest climates in the world, we'll be exposed to sand storms, crocodiles, scorpions, bunyips, sabre toothed wombats, scarce beer supplies and other dangers. But, at the end of each day there will always be good friends and a few cold ones waiting.

Follow Team Ethanol on our exciting journey.
