The next decade could see commuters speeding to work at about 300 miles per hour aboard magnetic levitation vehicles, according to a report by Argonne National Laboratories. But before "maglev" vehicles can become commercial successes, the report says, people need to stop thinking of them as high-speed trains. Instead, consider them low-flying aircraft. Argonne contends that maglev vehicles will be best suited to replace commuter aircraft. Plane flights under 600 miles are the least energy-efficient, and maglev "planes" should cut these fuel needs by up to 75 percent. Reportedly, the money saved by a 2,000 mile maglev network linking major cities world more than pay for its construction in 20 years. The quiet purr of levitating crafts would also be a balm for neighborhoods tormented by the roar of conventional takeoffs and landings. The technolog A. The Future of Transportation B.
