1.   American Superconductor drew technology from many sources, acquiring dozens of patents and licenses that finally enabled the company to produce a superconducting material suitable for a power line.

2.   Since returning to China, he has enjoyed lucrative benefits, several promotions, and the opportunity to market the new superconducting materials he is developing.

3.   Superconducting materials are brittle ceramics, difficult to form and nearly impossible to use.

4.   Five months after Japanese researchers stumbled upon a promising superconducting material, scientists on two continents have manipulated the material in ways that foreshadow its practical uses.

5.   Superconducting materials would dramatically reduce power losses.

6.   Unlike other superconducting materials, the material developed at Los Alamos continues to carry a large amount of current through the coils.
