- <p> Sometime within the next year, an eerily quiet, 280-ton
- lime-green ship will leave the docks at Mitsubishi Heavy
- Industries' shipyard in Kobe, Japan, for the first time. Though
- it will never speed faster than a leisurely 8 knots or carry
- more than 10 passengers, the Yamato No. 1's maiden voyage will
- be as unique as the first time Robert Fulton steamed up the
- Hudson River. Christened last week with a bottle of sake, the
- Yamato is the world's first vessel to propel itself through the
- water using the power of magnetism.
- </p>
- <p> Japanese government and industry are bringing to ocean
- travel the same technology they have used in the development
- of magnetically levitated trains. The Yamato, named for a World
- War II battleship, is powered by superconductive electromagnets
- that have been cooled down to an energy-efficient -425.47
- degrees F. The magnets shoot electrified seawater through a set
- of jetlike thruster tubes, thus greatly reducing the noise and
- vibration associated with the traditional rotating propeller.
- But before this system can be applied commercially, the size
- of the magnets, which now limits the vessel's speed and cargo
- space, will have to be reduced.
