TECHNOLOGY
The Power Of Magnetism
</hdr>
<body>
<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.
