Abstract

An apparatus is provided for intended use in agitating a fluid under cryogenic conditions. In one embodiment, the apparatus includes a fluid-agitating element for placement in contact with the fluid. The fluid-agitating element includes a superconductor, and a motive device is provided for causing the fluid-agitating element to agitate the fluid. In the case where fluid pumping is the desired outcome, an associated vessel may be provided including an inlet for receiving the fluid and an outlet for discharging the fluid as a result of the action of the fluid- agitating element. Related methods are also described, as is an impeller for use in connection with fluids under cryogenic conditions.
