A new technology is going to ripe, one that could transform our daily lives, help to form new industries, even remove world economic powers from their present positions. Unlike the wave of industrialization that began in the West and spread later to the rest of the world, the new developments are taking place in research labs all over the globe—and Asians are in the forefront. Physicists are creating a new class of materials that display an amazing property unforeseen even two years ago—superconductivity (超导体技术).

Used today only in specialized equipment, super conductors have the potential to radically change most of the electrical and electronic appliances found in the home, making them smaller, more powerful and efficient. They could free our cities of pollution by replacing petrol and diesel (柴油) vehicles with electric cars, and cut the cost of electricity. The new materials do something that even the best of conductors such as copper and silver cannot—they do away with all electrical resistance. The significances for energy storage are great.

The technology is in its early stage, still accessible to countries that decide to invest brains and money. For 75 years it had remained little more than a scientific curiosity with limited practical use because the phenomenon occurred only at extremely low temperatures. It was first observed in 1911 by a Dutch scientist named Heike Kamerlingh Onnes, who cooled mercury (水银) to temperatures below -269℃ with liquid helium (氦). Then in January last year, two IBM scientists, K. Alex Muller and J. George Bednorz, found a metal oxide ceramic (氧化陶瓷) that superconducted at -243℃. Their report went largely unnoticed until last December, when it was confirmed at a scientific meeting in Boston. Today Japan, India, China and other Asian countries all have their share of experts who spend their days and nights in labs, acting as midwives (助产士) to a new technology.
