INTRODUCTION: Maglev = magnetic + levitation. 1 st described by Robert Goddard, American Rocket Scientist, 1909 Scientific American. Next, 1912, French engineer, modeled it, Emile Bachelet, eddy-current repulsive levititation, amount of power needed too high to run… lack of funding.
Uses magnets to float the train along the track- o No friction o Cheat gravity o Very quiet Travels very fast (up to 250 mph). Requires all new train track to be built. Can’t run on old train track, needs magnet system.

CONTD. . - Expensive to build, but cheap to run. Cost for labor and energy: Air travel = approx. \$ 14 per mile. Maglev travel = approx. \$ 04 to \$ 10 per mile. Cost to build Maglev train tracks = \$5 million per two-way mile. Cost to build new airport , anywhere from \$500 million to \$1 billion.
. The electromagnets on the underside of the train pull it up to the ferromagnetic stators on the track and levitate the train. The magnets on the side keep the train from moving from side to side. A computer changes the amount of current to
