た。Thus, an endless coil (7) using a pipe (1) having a hollow inside and a superconducting ceramics coated on the inner wall could be produced. This Tco was 45K in the experiment. However, the choice of superconducting material can improve Tco. Further, by introducing liquid hydrogen into the hollow portion, the endless coil was used to form a closed circuit with zero resistance, so that it could be used as an electric energy storage device. In this embodiment, a power loss diode is provided at the input and output portions of the electric energy so that an infinite current does not flow when charged and discharged.
