> If there was a viable low cost superconductor that worked at temperatures up to 50 degrees Celcuis and atmospheric pressure, the implications would include:
It's important to note that a superconductor is a superconductor not just as a function of temperature, but also the amount of current carried, the critical current density[1], and magnetic field strength[2].
If the superconductor has a really poor critical current density, and the indicated numbers seemed to suggest so, it might not be viable for a lot of interesting applications in electronics and similar.
