[QUOTE="angie1, post: 868493, member: 3886"] Maybe this? It is being used more and more: Maglev (derived from magnetic levitation), is a system of transportation that uses magnetic levitation to suspend, guide and propel vehicles from magnets rather than using mechanical methods, such as friction-reliant wheels, axles and bearings. Maglev transport is a means of flying a vehicle or object along a guideway by using magnets to create both lift and thrust, albeit only a few inches above the guideway surface. High-speed maglev vehicles are lifted off their guideway and thus move more smoothly, quietly and require less maintenance than wheeled mass transit systems – regardless of speed. This non-reliance on friction also means that acceleration and deceleration can far surpass that of existing forms of transport. The power needed for levitation is not a particularly large percentage of the overall energy consumption; most of the power used is needed to overcome air resistance (drag), as with any other high speed form of transport.
