A new superconducting electrical transmission line for the High-Luminosity Large Hadron Collider uses new materials, a new cooling system and unprecedented technologies. 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. Find out more: https://home.cern/news/news/accelerators/successful-tests-cooler-way-transport-electricity | C
