Description: A computer-graphic illustration of electric-powered buses equipped with retractable windmills. The bus in the foreground is shown with it's windmill retracted. The bus in the background is shown with it's windmill extended. The windmill is retracted and stored,when the bus is driven. The windmill is extended when the bus is parked,so the bus can recharge it's batteries with wind energy.
