A Physical Ceiling That Has
Constrained Humanity for a Century
For over 100 years, engineers have accepted one immutable fact: industrial copper has a thermal conductivity ceiling of 401 W/m·K. Only silver — at 429 W/m·K — exceeds it. But silver costs ~70× more per unit weight.
This constraint has forced every engineer on the planet to compensate: larger heat sinks, heavier wiring, oversized cooling systems, lower chip densities, reduced battery efficiency. The cost — in wasted energy, materials, and performance — is measured in trillions.
