America's New Invention Could Replace Copper Forever

For more than a century, copper has powered homes, vehicles, power grids, telecom networks, and AI data centers. But a new wave of American materials research could challenge copper's dominance. This documentary-style explainer looks at aluminum-graphene conductors, graphene batteries, niobium arsenide nanowires, tantalum nitride heat transfer, carbon nanotube fibers, fiber optics, and light-based AI data center connections that may reshape the future of electricity.
