European Organization for Nuclear Research known as CERN developed the first 60-metre-long power transmission line made with magnesium diboride (MgB2) superconductor. It can transport electricity at a much higher current densities than ordinary cables without any loss. The line operates in Helium gas (He) up to 25 K (-248 degree Celsius) as the cooling system so reach its superconducting state.
Like a metal python, the huge pipe snaking through a CERN high-tech hall is actually a new electrical transmission line. This superconducting line is the first of its kind and allows vast quantities of electrical current to be transported within a pipe of a relatively small diameter. Similar pipes could well be used in towns in the future.
