 Initial studies showed that transmission voltages could be reduced to less than 300 Volts, mitigating arcing effects.Superconductor complications included cryogenic cooling systems with armor to protect against micrometeoroid impact and specialized connectors at segment, switch and power converter interfaces.It was shown that the tremendous magnetic repulsion force (on the order of 3.5 MT/meter radially at 1 Megamp) could be used for deployment and to present an extremely rigid structure.
