Superconductors Invade The Wireless World

Your article "Superconductors run into resistance" (Science & Technology, Apr. 12) was incomplete and far too pessimistic.

Illinois Superconductor is developing in partnership with AT&T and Ameritech Mobile Services, among others, with partial financial support from the U.S. Commerce Dept.'s Advanced Technology Program, new products based on high-temperature superconductors that would greatly improve the quality and capacity of wireless systems such as cellular telephones.

The picture you published showed me holding a prototype of a superconducting cellular-telephone product, but it was not identified as such in the caption.
