    I don't pretend to really understand the physics of this.

    In theory, could this be used to make a conductor, short of being a superconductor, with much less electrical resistance at room temperature than copper? If so, could this be used instead of superconductors in a supergrid to work around the problem of superconductor needing cooling? Just an idea.

    It might be one of those discoveries that only works at 10 degrees K maybe so you would need a cryo pump to actually use it. My cryo pumps takes a couple of kilowatts to run so if that is the case you are up against a big cliff there.

    There was no mention of even a direction to go to get this effect up to room temperature. That was my concern when I read that piece.
