Microsoft Tests Superconducting Cables for AI Data Centers

What Happened Microsoft has begun investigating high-temperature superconductors (HTS) as a replacement for copper wiring in data center power systems, according to a recent company blog post. The initiative comes as AI data centers face an unprecedented power crunch that’s straining electrical grids worldwide. The company specifically highlighted three key advantages of HTS technology: improved energy efficiency through reduced transmission losses, increased electrical grid resiliency, and dramatically reduced space requirements for moving large amounts of power.
