With increasing pollution and messy traffic jams, cities despite of their glittering life are losing charm as an ultimate abode for common men worldwide. In an attempt to improve city commutation, Tanzanian designer Walter Robert has developed a future taxi system named the “Renault Runner” that makes most out of renewable sources of energy to sustain the urban environment and make cities a better place to live. Featuring transparent solar panel windows to harness solar power and provide panoramic view of the surroundings, the urban taxi also saves space by conjoining to each other and forming a train. The Runner Train can connect up to three cabins with secure wireless commands. Running on multi-level hubless dynamo wheels, the Renault Runner also includes a power converter to accumulate kinetic energy as an added source of power, while intelligent LED lights make it an entirely zero-emission vehicle.
