Superconducting Karts Transform CERN's Underground Research Highways

CERN has engineered superconducting karts to replace bicycles in the 27-km Large Hadron Collider tunnel, dramatically improving infrastructure efficiency during the High-Luminosity LHC upgrade. The technology demonstrates how fundamental research facilities drive innovation with direct applications in aerospace and next-generation transportation systems. This cross-disciplinary project—inspired by collaboration with onsite schoolchildren—exemplifies how scientific research institutions can simultaneously advance cutting-edge engineering and nurture future scientific talent.
