Of the five different levitation technologies, two are likely to be applicable to low-speed operation. One system using controlled dc electromagnets to suspend large weights such as passenger carrying vehicles has become progessively more feasible technically, owing to advances in solid-state electronics. It is largely through these that a 1 t 4-passenger vehicle operating on a 30 m track has been built in the Applied Science Laboratories of the University of Sussex and has been demonstrated publicly. The operating experience of this vehicle has shown clearly that the controlled electromagnetic suspension is capable of providing a transport system that possesses passenger-attraction potential. This is meant to be a system that provides a frequent and thus highly reliable operation; for city-center or urban application it must be noiseless, and, if it is fully automatic and operating on segregated tracks, the guideway structure must be visually nonintrusive. Although the principal aim of eliminating physical contact is not so much to save energy as to obtain very high reliability, it is worth noting that a vehicle carrying eight passengers at 30 mile/h and using controlled dc electromagnets for suspension is likely to require less power than that wasted in the transmission unit of a car.
