With appropriate inductances added, that is the schematic
for a superconductor.  Which is why significant AC current
in a superconductor can cause it to heat up, and in some
cases quench (go non-superconducting) and even explode.

Most practical high current superconductors are imbedded
in a copper matrix for just this reason - it lowers the
resistance and increases the thermal capacity.  Many of
the fruit loops claiming to discover new high-temperature
superconductors in their garage don't understand stuff
like this (and many other things as well).

BTW, "Resistance is Futile" is also the corporate motto
for the RFID company "Alien Technologies" of Morgan Hill,
CA (http://www.alientechnology.com/).  When I visited,
their headquarters had Star Trek doors and the original
(according to the plaque) Robbie the Robot (from "Lost in
Space" and "Forbidden Planet") in the lobby.  Too much
startup funding?
