Students at the University of Karlsruhe in Germany designed and built an electric vehicle and the track that it runs on. The car can recharge using electrical conduits built into the surface of the track. It doesn't have to stop in order to recharge:
All the individual components of the car including its steering, breaks and chassis are designed by the students from high-tech materials. Apart from these, e-Quickie’s shell that plays a central role in the vehicle’s weight and aerodynamics is made from the carbon fiber to ensure the optimal mobility. The total weight of the car is 60kg, which, as per the project director, can be reduced to 40kg. The car is powered by a 2kw motor but achieves a top speed of 50 km/h. The batteries serve as a buffer, therefore they are much smaller than by electric cars, from which they draw energy exclusively.
