What do you think about the Superconductor Electricity Pipeline proposed by American Superconductor for carrying renewable generated electricity?

The proposal combines underground pipeline construction techniques with high capacity superconductor cables and multi-terminal DC-AC power electronic converters?

The result is a cost competitive high-capacity, long-haul electric transmission “pipeline” that has a low impact on the environment compared to overhead lines.
