Sweepers keep our pavements, paths and roads clean. For this purpose they are equipped with a powertrain for moving the vehicle, a blower for sucking up the dirt and debris and brushes for cleaning the ground. Researchers have now designed an electric hybrid sweeper. Compared to a conventional diesel-powered road sweeper, the electric hybrid sweeper driven by natural gas consumes less than half as much energy during the standard cycle for sweeping vehicles.
