The world already runs on superconductors.

Every scanner is a superconducting magnet. More than 30,000 are installed.

A superconducting gantry brought a heavy-ion treatment room from 600 tonnes down to under 300.

The magnet that resolves a protein structure runs at a few kelvin.

SQUIDs read the magnetic field of brain activity through the skull.

In the ground under Shanghai, Essen and Long Island. Rare because of the cold.

Goes normal in a millisecond and swallows a short circuit.

A 3.6 MW superconducting rotor ran on a Danish turbine for 650 hours.

Current parked in a loop and handed back in milliseconds.

Most of the largest processors are superconducting circuits, held near absolute zero.

Superconducting nanowires count single photons for quantum links and lidar.

Switching at a fraction of the energy of silicon. Demonstrated for decades, never volume-made.

Sensors that measure one photon by the heat it leaves behind.

Japan's superconducting maglev reached 603 km/h on a test track.

A megawatt motor light enough to fly needs a cryostat that survives a wing.

A 36.5 MW superconducting motor was built and tested for naval use.

1,232 superconducting dipoles bend the beam around 27 km at CERN.

Twenty tesla, and the reason a compact tokamak is credible at all.

High-gradient magnets pull iron out of clay at industrial rates.

Heats a metal billet far more efficiently than a copper coil.
