Superconductors allow electricity to be conducted with little to no resistance. One use of super conductors that is especially interesting to me is that in certain areas of Japan and Germany they have experimental magnetic levitation trains. These trains can travel at higher speeds, are more efficient, and are environmentally friendly. These trains use superconducting magnets to lift them above the rails and almost eliminate friction. This makes me wonder about the potential to tie this technology into cars, which would be beneficial but would require a lot of work, just a thought that popped into my head while reading about this.
Other uses of superconductors are they have been used experimentally to speed up connections between computer chips, superconducting coils are used in MRI machines, and some high energy practical accelerators.
