I've seen electrical charges before for cars, but this is in fact the best example I've ever seen, simple, functional, clean... and without the typical "green" slogan which I am bored of it... No green icons, or sentences, or color (although there is a Eco in the name...). They have thought about it, and you can appreciate this fact just by looking to the final product. The video doesn't tell much that you couldn't guess by yourself but it's ok to get some interesting picks.
