CERN levels up with new superconducting karts (home.cern)

CERN is testing superconducting “karts” designed to move staff and equipment through the 27-km underground Large Hadron Collider tunnel during Long Shutdown 3, when the accelerator will be upgraded to the High-Luminosity LHC. The karts use dozens of superconducting engines that levitate the vehicle via the Meissner effect once cooled, and early tests have shown speed improvements. CERN is also discussing potential societal applications, including links to European startup Quantum Mushroom for aerospace and anti-gravity concepts.
