| Abstract: | Using single-domain high temperature superconducting bulk,a demonstration apparatus of superconducting flywheel energy storage for opening laboratory or classroom teaching was realized.The apparatus accelerated a flywheel to a very high speed and the rotation energy of the flywheel was conserved due to the very low friction of the magnetic suspension bearings.By electromagnetic induction,the rotation energy could be transformed into electric energy to drive LED for a long time. |
