1970 Firebird gets prepped for Stone Soup Project raffle

Detroit classic-rock station 94.7 WCSX started this year's Stone Soup Project for charity last month, and things with the 1970 Pontiac Firebird are going swimmingly. When finished, the car will be raffled off for HolyCross Children's Services, a charity dedicated to providing social services to kids in Michigan. Last year, the Stone Soup Project took on a classic 1969 Mustang Boss.

“Where is the sustainable vehicle design?”

The notion of a 'new paradigm in car design' was a theme running through talks by five panelists at London's Royal College of Art last week, who debated "Seriously now, where is the sustainable vehicle design?" Despite disparate backgrounds, there was broad agreement that a truly sustainable form of personal transportation is unlikely to come from an established automotive firm any time soon. Panelist Rob Holdway of Giraffe Innovation was most vocal in his approach to the subject, saying "Frankly, I think the car is unacceptable - we hear a lot about the sustainable car, but I don't think there is such a thing as a sustainable car". The audience - made up mainly of RCA students - also heard from Nico Sergent of Riversimple about how the company's seven-point business model, and its open source strategy, incentivized the company to build a truly sustainable car and mobility package that the current auto model simply doesn't allow.
