G-Wiz electric car

One of the easiest ways to help Mother Earth is to ditch your petrol-guzzling harbinger of death in exchange for a G-Wiz. It's a fully electric car, meaning you never, ever have to fill it up with petrol. Just plug it into the mains at home or at your local garage, charge it up for eight hours, then drive to your heart's content. Or until the battery dies. Fine, it might look like a rabbit hutch on wheels, but the G-Wiz costs less than 1p per day to run.
