Фрагмент работы

Magnetically levitated ground transportation, or 'maglev,' is an advanced mode of surface high speed transportation whereby a vehicle gliding above a guide track is suspended, guided, and propelled by magnetic forces. Because they never touch the guide
track causing friction, maglev vehicles can be designed to travel at extremely high speeds, 500 kilometers per hour (300 miles per hour), or more!
Americans traveled 3.2 trillion passenger kilometers (2 trillion passenger miles) by car, truck, bus, and public transit, and 9.8 billion passenger kilometers (6.1 billion passenger miles) on Amtrak. As populations have grown the traditional systems have become stressed. Congestion on highways and at airports not only wastes time and fuel and increases pollution, but constrains mobility to the extent that economic growth and productivity are adversely affected.
