Applied Superconductivity Research - University of Cambridge B.A.Glowacki Market and material projections: (a) Price/performance of NbTi, Bi2223 and YBCO conductors versus years; (b) Projections of the LTS and HTS market which is sheared between electronics, power, industrial processing, medical care and transportation estimation conducted at International Superconductivity Industry Summit, Yamanashi 1996, numbers corrected according to data in early 2003 (solid lines). Corrected projection conducted at Cambridge University in Military use of expensive Coated Conductors is different from civilian market. Development of YBCO coated conductor is a technology driver, not a Cu or Fe replacement. 1. LTS & HTS market prediction
