The invention relates to vehicles for transporting persons and/or goods, which vehicles travel on roads or alternatively on rails and at least partially use electrical energy using electric motors as drive units, wherein the electrical energy used is predominantly or substantially produced within the vehicle by converting kinetic energy, in particular components of the kinetic energy that are caused on the vehicle bodywork as gravitation effects and components of the kinetic energy from curve centrifugal forces and acceleration motions of the vehicle body, the vertical dynamic acceleration motions of the wheels and wheel suspensions, and other components, wherein the electrical energy generated in such away is temporarily stored in chemical energy stores (batteries) and/or other suitable storage media, for example, high-power capacitors or flywheel stores, until the electricity is used in the vehicle drive motors and/or other loads.
