To reduce the dependance of today’s mobility needs on fossil fuels, it is not enough to just change the energy source. As an example, the cruising range of today’s e-cars is sufficient for commuting, but still too small for traveling longer distances.
Enter Christian Foerg http://redir.ec/foerg , a young designer from Munich who just finished his diploma thesis at FH Munich with his “Speedway” electromobility concept. It is based on an electric vehicle which is supported by an external linear motor embedded beneath the pavement of conventional highways. While the electric vehicle runs on battery power in towns and in the countryside, on the autobahn it is driven by a drifting magnetic field. The concept already is used in passenger carriers on airports (JFK’s Airtrain), in subways (Tokyo’s Toei Oedo line), and in Shanghai’s Transrapid train.
Foerg’s feasibility study calculates costs of 8.5 million Euros per highway kilometer to convert existing highways. This is in line with the costs of building or rebuilding conventional highways, ranging from 6 to 12 million Euros per kilometer. In Foerg’s concept, the highway still can be used by conventional cars and the system can be implemented step by step.
