This open-topped beauty is the Wind Explorer, a German-made electric car that's just driven across Australia. And it only used around $13 of electricity on its 18-day trip.
It's powered by two methods—a motor running on an internal battery that can be charged by the mains supply or a portable wind turbine, or, er, dragged along by kites. The turbine is a 20-foot-high telescopic bamboo mast that can be deployed in half an hour. Not particularly convenient for the daily commute, but a nice bit of thinking about how we might survive once the planet's oil's all been guzzled. [Wind Explorer via Like Cool]
