Here's an interesting design for a filling station. Posted on ecofriend.org, this solar panel filling station will be able to charge anything from your car to your MP3 player. They already have a prototype in the works and it was said it could charge 8 cars in one go.
"Designed by Michael Scherer from Brixen, the E-Move Charging Station is equipped with eight mono-crystalline photovoltaic modules, which collectively supply 1.76KWp of solar power
The article doesn't mention how the power is transferred to the car, but I think it'd be cool if it did it through ambient radio wave power. It most likely doesn't though...
