A Civilization advance.
When an electric current passes through any material, some part of that current is lost to resistance. A material with little resistance to the flow of electricity is called a conductor, and these materials are useful for building electric devices. Many conductors, when cooled to temperatures near absolute zero, lose all resistance to current. A material with no resistance to the flow of electricity is a superconductor. Recent developments hint that some unusual materials may be superconductive even at room temperatures.
