The BBC has a short video overview of the Sexy Green Car Show at the Eden Project, Cornwall, UK.
They don't go in depth about much of anything, but it gives you an idea of what the show looks like and what some of the cars shown there are. We can see a few electric and hybrid vehicles, but flex-fuel cars are also numerous. You can see a list of all the cars here. If you are in the area and want to see for yourself, the show is open from May 23 to May 31. More details here. The BBC video is here.
