In 2030 the traffic system in cities is going to be dominated by bicycles. After a successful energy revolution the energy is no longer derived from fossil sources but generated by the sun. A part of the traffic system is a rickshaw, powered by an electric motor. For this, it does not have to be charged at a station regularly. It is charged just by solar energy. Photoelectric cells are included into the roof of the rickshaw, which generate hydrogen be the power of the sun. The hydrogen is stored and can be converted into electrical energy if it is necessary. A battery is not needed.
