The analysis of an existing superconducting power transmission cable design indicated that economic benefits in the area of refrigeration can be derived from the substitution of Nb$sub 3$Ge superconductor for the presently planned Nb$sub 3$Sn. However, the cost of Nb$sub 3$Ge must be comparable to that of Nb$sub 3$Sn, which is achievable when preparing Nb$sub 3$Ge by the chemical vapor deposition. Alternatively, technical benefits can be obtained. The most essential and prerequisite requirement is that the Nb$sub 3$Ge critical current density be improved significantly over the present state-of-the art. Other properties of Nb$sub 3$Ge are generally suitable for the transmission line application and/or require only moderate improvements. (auth
