Abstract
Abstract A flywheel-driven vehicle is powered by an electric motor. The rotation of the flywheel is initiated and maintained by an electric motor, wherein the electric motor is powered alternatively by a plurality of batteries (or sets of batteries). A charger assembly is connected to the plurality of batteries. In operation, one battery at a time powers the electric motor while, simultaneously, the other battery(s) is/are being recharged.
