7th World Solar Challenge Underway 151
downundarob writes "At around 200310182230 UTC the World Solar Challenge will leave the start line. Entrants will traverse more than 3,000km of the Australian continent from tropical Darwin to balmy Adelaide, in cars powered by nothing more than the sun.
One of the unique propositions of the World Solar Challenge is that it is run in one stage. Once competitors have left Darwin at 8am on the first day, they are on their own. Apart from compulsory stops at the seven checkpoints, each team endeavours to travel as far as it can each day, but must make camp by 5pm each evening."

Volkswagon Phaeton [vwvortex.com]
$60k-$100k is currently out of most of our price ranges, however it does exist.
A further possibility for controlling the atmosphere in the Phaeton is offered by the sliding sunroof. It may be had in both glass and solar versions as an option. The sunroof is operated via a preselector in the roof-mounted console. The solar sunroof is the biggest of its kind on the market. The 28 integrated solar cells provide 24 Watts of energy, which is also used to power the electric fan when the vehicle is at a standstill. In the summer this reduces the interior temperature by up to 20 degrees. Unpleasant air currents and loud wind noise when the roof is open are prevented by a speed-sensitive, electronically-controlled wind deflector.
