Method and apparatus for containing and directing a flowable superconducting slurry

An apparatus for containing and directing a superconductor, comprising:

• an elongated tube;
• and
• a superconducting slurry at least partially filling the tube;
• wherein the tube is substantially flexible at room temperature;
• wherein the superconducting slurry includes superconducting particles suspended in liquid nitrogen;
• and
• wherein the superconducting particles have a Tc greater than the boiling point of liquid nitrogen.

A bulk superconductor, comprising:

• a cryogenic hose having a proximal end and a distal end;
• a superconducting slurry at least partially filling the hose, comprising:
• liquid nitrogen;
• ceramic oxide superconducting particles having a Tc in excess of the boiling point of liquid nitrogen;
• wherein the ceramic oxide particles are suspended in the liquid nitrogen;
• wherein the electrical resistance from the proximal end to the distal end is zero.

A method of transmitting electrical energy, comprising the steps of:

• a) providing a superconducting slurry having a Tc;
• b) constraining the slurry in a container;
• c) inducing electric current to flow through the slurry;
• and
• d) extracting electric current from the slurry.
