A step in the right direction, certainly, but "The superconductor has
one serious limitation, however: it survives only under extremely high
pressures, approaching those at the centre of Earth, meaning that it
will not have any immediate practical applications."

Run a power cable through the centre of the earth so we can buy solar
power from Australia when it is dark here?
