The BBC ran a fascinating piece on their series "Ethical Man" - this is about a guy trying to minimise his carbon footprint. Having explored advances to minimise his carbon footprint in the UK, he travelled to the US (by plane!) to see how joe public in the USA is looking at ways to reduce their carbon footprint. He travelled by Greyhound Bus (from Michigan) to Detroit - to visit GM and to see GM's new carbon friendly car, The Volt. The Volt has been designed to run on electricity and unlike the hybrid, which has capacity to run on electricity and petrol, the Volt is puely an electrically power vehicle/engine. GM ought to be congratulated for taking this bold step to embrace the era of reduced carbon emmissions, I think. The presenter drove the car and said that it was like driving an ordinary fossil fuelled car - except that the acceleration was much better in the Volt. Hopefully this car will sell well.
