Copper has powered the modern world for more than a century. Now American researchers are developing technologies that could replace it in some of the places where demand is growing fastest.
Inside future computer chips, researchers at Cornell University have demonstrated an unusual material called niobium arsenide that can outperform copper as wires become extremely small. At Pacific Northwest National Laboratory, scientists are improving copper and aluminum by adding tiny amounts of graphene. Meanwhile, AI data centers are beginning to replace more electrical connections with optical systems that move information using light.
In this documentary, we explore why copper is becoming harder to use inside advanced chips, how graphene composites could reduce the amount of copper needed in electric vehicles and power equipment, and why companies like NVIDIA, Broadcom, Corning, and Meta are investing heavily in optical connectivity for AI infrastructure.
These technologies matter because China produces roughly 44 percent of the world’s refined copper. As electric vehicles, renewable energy, power grids, and data centers drive demand higher, that refining capacity gives China an important position in the global supply chain.
America does not need to completely replace copper to change that equation. If new materials use less copper in motors, replace microscopic wires inside chips, and move more data through light instead of metal, future industries may simply need less copper than expected.
