If electric cars are really going to compete with the gas-guzzling kind, we're going to need new infrastructure — mainly charging stations so people can juice up when they're on a road trip. And if you have to dot the country with new charging structures, doesn't it make sense to make them awesome-looking?
The "solar forest," a concept from designer Neville Mars, does that while also being extra-efficient. The solar "trees" don't just look great — they also move around to maximize sun exposure, plus they keep the cars below shaded and cool.
